Undersized and oversized wicks fail in opposite directions, and a handful of symptoms sit at both ends of the range. This page separates them column by column, gives you the discriminating test for the ambiguous ones, and reduces the whole diagnosis to one number you can take with a clock.

Quick answers — read this first
How do I know if my wick is too small? The melt pool stops short of the glass and stays short, the candle tunnels, the flame is low, the wick sinks into liquid wax and the scent is faint. The confirming number: the pool has still not reached the wall after four hours.How do I know if my wick is too large? The pool reaches the wall in under two hours and keeps deepening, the flame is tall or restless, the tip carbonises into a mushroom, the glass sooties, the jar is uncomfortable to hold and the candle is finished far sooner than the wax weight suggests.
Which symptoms mean nothing on their own? A flame going out and soot both occur at each end of the range. So does weak throw. Each needs a discriminating test, and all three are set out in the ambiguous middle.
What should I do before buying a different wick? Time one burn. Most makers re-wick when they should have measured first, and about a third of "wick problems" turn out to be a short first burn, a draught, a fragrance load at the ceiling or the wrong wax grade.
The short answer
Too small: pool stalls short of the wall, tunnelling, small flame, wick drowning, weak throw. Over four hours to a full pool.
Too large: pool at the wall in under two hours, deep pool, tall or flickering flame, mushrooming, soot, hot jar, top notes burnt off, short burn life.
Both ends: a flame going out, soot in some conditions, and weak throw. Use the discriminating tests, not the symptom.
In this guide
Wick size is a spectrum, not a pass or fail. The failures at the two ends are opposites, which is what makes them diagnosable: a candle cannot be simultaneously tunnelling and running a pool that is too deep. Where a symptom does appear at both ends — a flame going out, soot — the discriminating tests are in the section below the table.

Straight answer
How do you tell whether a candle wick is too small or too large?
Light the candle, note the time, and watch two things: how long the melt pool takes to reach the glass, and what the flame does while it gets there. If the pool has not reached the wall in four hours, the wick is too small, and you will also see tunnelling, a low flame, a wick sinking into wax and weak throw. If the pool reaches the wall in under two hours and then keeps deepening, the wick is too large, and you will also see a tall or restless flame, mushrooming, soot on the glass, a jar too hot to hold and a candle that burns out early with its top notes scorched off. Two to three hours to a full pool is the target band. Three symptoms sit at both ends and prove nothing by themselves — a flame that keeps going out, soot, and weak scent — so each gets its own discriminating test below. Before you order a different wick, confirm the fault is the wick at all: a short first burn, a draught, a fragrance load at the wax ceiling and the wrong wax grade all imitate wick faults, and re-wicking will not fix any of them. Test wicks start at ₹5.90 each.
One line: time the burn to a full melt pool — under two hours means the wick is too large, over four means it is too small, and everything else on this page is confirmation.
A three-wick test spread costs less than one wasted production batch. Eco Candle Wicks Thin (C1) at ₹59 for 10, Cotton Braided Wicks at ₹120 for 10 and Eco Candle Wicks Thick (C2) at ₹188.80 for 20 give you three steps across the range for ₹367.80.

The two-column diagnosis
An undersized wick and an oversized wick do not give you a worse and a better candle. They give you two different broken candles, breaking in opposite directions.
This is the table the rest of the page exists to support. Read down one column at a time. If four or more lines in one column describe your candle, you have your answer — go to the three-jar protocol and test one size up or one size down. If you are collecting a line from each column, you are probably not looking at a wick fault at all, and the last section is the one you want.
Symptom set by direction · same wax, same jar, same fragrance load
Wick too small in the left column, wick too large in the right
| Wick too small — under-wicked | Wick too large — over-wicked |
|---|---|
| Melt pool. Stops short of the glass and stays short, burn after burn. A ring of unmelted wax survives every time | Melt pool. Reaches the glass well inside two hours, then goes on deepening for the rest of the burn |
| Time to full pool. Over four hours, or never | Time to full pool. Under two hours, often under ninety minutes |
| Pool depth. A thin film, often under 5 mm, sitting in a well | Pool depth. Well past 13 mm, sloshing when the jar is moved |
| Wax waste. Tunnelling. A hard wall clings to the glass and never burns — 20–40% of what the customer paid for | Wax waste. None left, but it goes fast — finished long before the burn hours on your label |
| Flame. Small and low, barely clearing the wax, dimming as the pool fills in around it | Flame. Tall, restless, leaning and flaring; never settles even in still air |
| Wick. Sinks into the pool and drowns. Blotting it buys you twenty minutes | Wick. Tip carbonises into a mushroom head that sheds carbon and worsens as it grows |
| Glass. Clean, but with an obvious wax wall and a tunnel down the centre | Glass. Grey to black soot above the flame, spreading down the sides |
| Jar temperature. Cool to lukewarm after two hours. Comfortable to hold all day | Jar temperature. Too hot to pick up bare-handed within an hour or two |
| Scent. Faint. The fragrance is in the wax but there is almost no surface to release it from | Scent. Loud for ten minutes, then flat and slightly burnt — top notes cooked off |
| Complaint. "It doesn't smell of anything", "there's loads of wax left" | Complaint. "It's smoking", "the jar got too hot", "it finished really quickly" |
Two lines are worth more than the rest combined, because they are the only ones you can put a number on without equipment: time to full melt pool and pool depth. Everything else is a judgement, and judgements drift — two makers will disagree about whether a flame is "tall", and neither will disagree about a clock. That is why the measurement section reduces the diagnosis to a stopwatch reading, and why the sibling guides on each symptom — no full melt pool, mushrooming, drowning — come back to the same measurement.
One symptom is not a diagnosis
Any single line above can be produced by something other than the wick. A tall flame appears in a draught, soot appears at a high fragrance load, a shallow pool appears when the burn was cut short. Four lines from one column is a diagnosis; one line is a hypothesis. Count before you order.The ambiguous middle — symptoms that appear at both ends
Most troubleshooting tables quietly leave out the symptoms that refuse to sort themselves. There are three, they are among the most commonly reported faults in candle making, and pretending each belongs to one column is how makers buy the wrong wick twice.
Ambiguous symptom 1 — the flame keeps going out. Too small: the wick cannot burn wax as fast as it draws it, liquid wax rises over the base of the flame and it drowns. It dies early — inside the first two hours, with a narrow pool that never reached the glass and a wick tip visibly submerged. Too large: the same candle can die late, once an over-fast pool is deep enough to swamp a wick that has burned down into it, or once a heavy mushroom head chokes the flame off its fuel. The discriminating test: look at the pool the moment it dies. Narrow, shallow, short of the wall, died in hour one or two — too small. Wide, reached the wall quickly, over 13 mm deep, carbon ball on the tip — too large. Full mechanism in why does my candle wick keep going out and why is my candle wick drowning in wax.
Ambiguous symptom 2 — soot. Too large is the usual cause and it looks like it: soot is continuous from about twenty minutes onward, the flame is tall and above 40 mm, the deposit builds evenly round the glass and the jar is hot. Too small soots differently — intermittent, in puffs, thrown off a mushroom head or a partially drowned wick shedding unburnt carbon rather than a hot oversized flame. That flame is small and smoky, not tall and smoky, and the glass stays comparatively clean between puffs. The discriminating test: trim to 5 mm, relight in a closed room with no fan and no open window, and read flame height at twenty minutes. Tall, steady, sooting continuously — too large. Small, low, smoking in bursts — too small, or a fuel the wick cannot cope with. Trim with a wick trimmer at ₹295, or the alternative listing at ₹177.
Ambiguous symptom 3 — weak scent throw. The one that costs makers the most, because the instinct is to add fragrance oil and it is wrong in both directions. Too small: the pool is the surface fragrance evaporates from, and a pool reaching only 45 mm across in a 70 mm jar releases from 15.9 cm² instead of 38.5 cm² — about 41% of the surface, so about 41% of the release. Too large: the pool overheats, the top and heart notes flash off in the first fifteen minutes, and what is left for three hours is the flat base plus a burnt edge. The discriminating test: smell the room at 30 minutes and again at 120. Weak at both with a small pool — too small. Strong at 30 and duller, slightly scorched at 120 with a deep pool and a hot jar — too large.
The honest caveat on mushrooming. It leans heavily towards over-wicking and belongs in the right-hand column, but it is not exclusive to it: a correctly sized wick still mushrooms when asked to burn more than wax — a load at the wax maker's stated ceiling, or heavy dye, gives the flame material it cannot fully combust. The discriminating test is a control jar: plain, undyed, unfragranced wax, same wick, same container. Clean control and a mushroom in the production candle means the formula is the variable. Mushroom in both means the wick is too large. This is covered in detail in why does my candle wick mushroom.
The CSI principle
A symptom that appears at both ends of a range carries no information until you pair it with a measurement.
"My wick keeps going out, so it must be too small" is the most expensive assumption in this cluster, because the fix for an over-wicked candle that drowns late is the exact opposite of the fix for an under-wicked one that drowns early. Pair the symptom with time-to-full-pool and pool depth and the ambiguity disappears.
The single measurement that resolves most cases
Time to full melt pool. That is the whole test: light the candle at a known time in a closed room and record when liquid wax first touches the glass all the way round. It needs no instrument at all, and it separates the two columns above more reliably than any flame observation.
The verdict scale · one burn, one number
What the clock tells you
| Time to full pool | Verdict | What to do |
|---|---|---|
| Under 2 hours | Over-wicked | Step down one size and re-test. The soot, the mushroom and the hot jar should go with it |
| 2 to 3 hours | Correct | Nothing. Lock the wick into the recipe, record it, and stop changing it |
| 3 to 4 hours | Borderline | Acceptable in a wide jar, marginal in a narrow one. Re-test before deciding |
| Over 4 hours, or never | Under-wicked | Step up one size. Do not rescue it by burning longer — four hours is where a single burn ends |
The four-hour figure is not arbitrary. Standard candle care guidance is to end a single burn at around four hours, so a candle that cannot open its pool inside that window will never open it in normal use. From burn two onward it builds a memory ring, and the tunnel is then permanent — the mechanism behind candle tunnelling. The other end is equally practical: a pool that opens in ninety minutes has three more hours of the same burn in which to do nothing but deepen and overheat. The full timing guide is here.
The reason one wick behaves differently in two jars that look similar is that pool area grows with the square of the diameter. Area is πr², so a jar 10 mm wider is not 10 mm harder to wick — it is a proportionally much larger surface for one flame to hold molten. That is why a wick validated in one container has to be validated again in the next.
Full melt pool area by internal jar diameter · A = πr²
Why 10 mm of extra diameter is never a small change
| Internal diameter | Radius | Full pool area | More surface than the row above |
|---|---|---|---|
| 45 mm | 2.25 cm | 15.9 cm² | — |
| 50 mm | 2.50 cm | 19.6 cm² | +23% |
| 55 mm | 2.75 cm | 23.8 cm² | +21% |
| 60 mm | 3.00 cm | 28.3 cm² | +19% |
| 65 mm | 3.25 cm | 33.2 cm² | +17% |
| 70 mm | 3.50 cm | 38.5 cm² | +16% |
| 75 mm | 3.75 cm | 44.2 cm² | +15% |
| 80 mm | 4.00 cm | 50.3 cm² | +14% |
| 90 mm | 4.50 cm | 63.6 cm² | +26% |
Set against the partial-pool arithmetic, the scent complaint explains itself. In a 70 mm jar the full pool is 38.5 cm²; a pool stalling at 50 mm across is 19.6 cm², or 51%, and at 45 mm it is 15.9 cm², or 41%. The customer is not getting slightly less throw — they are getting less than half the releasing surface the candle was designed to have, and no amount of extra fragrance oil buys that surface back. The wick buys it, and the wick costs ₹5.90. Diameter-by-diameter starting points are in the wick guide by diameter.
You cannot see a wick that is 15% too small. You can see a clock that says four hours.

The three-jar test protocol
One jar tells you whether the candle in front of you works. Three jars burned side by side tell you which wick to buy for the next five hundred, because wax, fragrance, pour temperature, cure and room are held constant — so the only thing that can explain the difference is the wick.
1
Pour three identical jars, wicked one step apartSame wax, same oil at the same load, same pour temperature, and three of the same jar from one pack so the internal diameter is genuinely identical. The only variable is the wick: one below your current size, your current size, one above. Centre each with a wick centering device at ₹118 for 5 or a bamboo wick holder at ₹118 for a set of 5 — an off-centre wick fakes an under-wicked result on one side of the jar.
2
Cure them together, then test them togetherCure all three in one carton at the same room temperature for the same number of days. A wick tested at 48 hours against one tested at day 14 is not a comparison. Write the pour date on each base.
3
Trim every wick to 5 mm and light all three at onceSame room, door closed, no fan, no air conditioning across the bench, no open window. Note the clock time. A draught on one jar and not the others invalidates the whole test, and it is the commonest way makers convince themselves a good wick is bad.
4
Record at 30, 60, 120, 180 and 240 minutesAt each checkpoint write down the eight fields in the record sheet below, on paper, at the bench — not from memory afterwards. The 120-minute reading decides most tests; the 240-minute reading is where you stop, because four hours is the end of a single burn.
5
Judge jar temperature with the back of your handA surface thermometer on glass is unreliable, so use your hand: hold the back of it flat against the jar at the pool line for three seconds. Comfortably warm is correct. If you have to take your hand away, the wick is too large for that container — record "too hot to hold" and move on.
6
Repeat the winner over three consecutive burnsBurn one is not proof. A wick that opens a clean pool in 2 hours 20 minutes on burn one and mushrooms heavily on burn three has failed. Only after three burns do you write it into the recipe and order the pack size you need. Then leave it alone.

| Pool depth | Millimetres against the inside of the glass at the deepest point | 6–13 mm at the four-hour mark |
| Flame height | Millimetres from the wax surface to the flame tip, in still air | Roughly 25–40 mm and visibly steady |
| Mushrooming | None / slight / heavy, and whether carbon drops into the pool | None to slight after four hours |
| Soot | None / intermittent / continuous, and where on the glass it sits | None, with glass still clear above the flame |
| Jar temperature by hand | Cool / warm / hot / cannot hold — back of the hand, three seconds | Warm and holdable throughout |
| Verdict | Under-wicked / correct / over-wicked, plus the line that decided it | Backed by the clock reading, not by an impression |
Two purchases that make the sheet worth filling in
A candle making weighing scale at ₹354 and a pen thermometer at ₹354 are what stop the three jars differing in anything but the wick. Without them fill weight and pour temperature drift between jars and it is no longer a wick comparison. ₹708 once, against ₹367.80 of wicks spent repeatedly on tests that prove nothing.The CSI wick range with live pricing, laid out so the three-step spread is easy to order in one go.

Cotton · two sizes · the default test pair
Eco Candle Wicks — Thin (C1) and Thick (C2)
One product, two sizes, so you get a real step up and a real step down without changing wick type. Thin C1 is the cheapest wick per piece in the catalogue at ₹5.90, at every pack size from 10 to 1,000. The Thick (C2) 10-wick pack is out of stock on the pull date; the 20-pack is the smallest Thick option buyable.

Cotton braided · the third step
Cotton Braided Wicks Ready Made
Ready-tabbed cotton braid, and the third point in a spread when Thin reads under-wicked and Thick reads over-wicked in the same container — the gap where most makers give up and settle for the less bad of two wrong answers. At ₹12.00 per wick it costs less than one ruined 200 g pour. Pack pricing is flat, so the 10-pack costs the same per wick as the 1,000-pack; there is no reason to over-order before the test is done.

Wooden · a different flame entirely
Performance Wooden Wicks (Imported)
Worth knowing about, but do not reach for these to fix a cotton sizing problem. A wooden wick burns a wide, low, flat flame instead of a tall round one, so most visual cues in the two-column table change meaning — flame height in particular is not comparable, and you re-run the whole protocol from scratch. This is a product decision, not a troubleshooting step, and at ₹59.00 per wick in the smallest pack it is the most expensive one in the range.
| Pack | Price | Per wick | Saving |
|---|---|---|---|
| Pack of 10 | ₹590.00 | ₹59.00 | — |

What is not a wick problem
The commercially convenient advice on this page would be "buy more wicks". We sell the wicks. Most makers who think they have a wick problem should have started a clock instead.
Four faults imitate a wick fault closely, and not one of them improves when you change the wick. Rule all four out before you order a different size. It takes one evening and costs nothing.
Rule these out first
Looks like a wick fault · is not a wick fault
| Actual cause | What it imitates | How to tell, and where to go next |
|---|---|---|
| A short first burn | Under-wicking — tunnelling, a pool that never reaches the wall | Wax has a memory: end burn one before the pool reaches the glass and every later burn follows that smaller ring, whatever the wick. Ask whether burn one ran the full two to four hours, then read is my candle tunnelling because the wick is too small |
| A draught | Over-wicking — a tall, flickering flame, soot, an uneven pool | Soot and melt sit on one side. Close the door, switch off the fan, move away from the window and relight; a flame that settles within ten minutes clears the wick |
| Fragrance load at or over the wax's stated ceiling | Both ends — drowning, soot and mushrooming on a correct wick | Burn an unscented, undyed control jar with the same wick and container. Clean control plus dirty production candle means the formula is the variable |
| The wrong wax grade for the vessel | Under-wicking — a slow, shallow, reluctant pool | Pillar wax is formulated to hold its shape out of a mould, not to pool. Confirm you are using a container wax, then see tunnelling troubleshooting: wax, wick, jar or formula |
On the fragrance point, the ceiling is set by the wax manufacturer and it is not one number for all soy: Luxury Soy Wax Chunks are rated up to 13% and Luxury Soy Wax CSI 464 flakes up to 10%. Those are wax formulation limits — how much oil that wax will hold in solution — not regulatory limits. Oil that will not stay in solution gets drawn up the wick, and a wick asked to burn oil rather than wax will drown, mushroom and smoke whatever size it is. Work to the figure for the wax you actually bought, from the Candle Wax collection.
Argued against our own interest, plainly. A three-wick spread costs ₹367.80 and we would be glad to sell it to you. But if the real fault is a first burn blown out after forty-five minutes, that ₹367.80 buys three jars that all tunnel and the same wrong conclusion twice. Time one burn before you buy anything. The measurement is free, and most makers who arrive convinced their wick is wrong find their process is wrong instead. The candle that needs re-wicking will still need it tomorrow.
One last case belongs here rather than in either column: a jar simply too wide for a single wick. Past roughly 80 mm of internal diameter — 50.3 cm² of pool — one cotton wick will only reach the glass by running hot enough to soot it and overheat the container. That is a double-wick container, not an under-wicked candle waiting for a bigger wick, and stepping the size up is how makers end up over-wicked and still tunnelling at the edges at once — the one combination the two-column table cannot explain. Check internal diameter before you blame the wick; the Containers collection lists 80 products.
Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. On a page about wick sizing the commercially convenient advice would be to buy a spread of every size and test them all. Instead the first instruction here is to start a clock, which costs nothing and sells nothing, because a maker who re-wicks a candle whose real fault was a forty-five minute first burn has spent money and learned the wrong lesson — and will spend it again next month.
Every price, pack size and stock note on this page is taken from live CSI stock on 10 September 2026 and links to the product page, where current pricing and specification always take precedence. Where a variant is out of stock on that date — the Eco Candle Wicks Thick (C2) 10-wick pack — it is flagged rather than quietly listed. The melt-pool areas are plain geometry, calculated as πr² from nominal internal jar diameters, and they hold for any supplier's jars, not just ours.
The timing bands, the flame-height range and the pool-depth range are working thresholds from standard container-candle practice, not laboratory measurements, and they are stated as thresholds you verify on your own bench with your own wax.

Frequently asked questions
How can I tell if my candle wick is too small or too large?
Time how long the melt pool takes to reach the glass all the way round. Under two hours means the wick is too large; over four hours means it is too small; two to three hours is correct. Confirm with the symptom columns: a too-small wick gives a stalled pool, tunnelling, a low flame, a drowning wick and weak throw, while a too-large wick gives a deep pool, a tall or flickering flame, mushrooming, soot, a hot jar and a short burn life. Four lines from one column is a diagnosis.
My candle wick keeps going out — is the wick too small or too large?
It can be either, which is why the symptom alone is useless. Look at the pool at the moment the flame dies. Narrow pool that never reached the glass, shallow, died within the first two hours — the wick is too small and it is drowning in wax it cannot burn. Wide pool that reached the glass quickly, more than 13 mm deep, with a carbon ball on the tip — the wick is too large and it has either been swamped by an over-deep pool or choked by its own mushroom. Both cases are worked through in why does my candle wick keep going out.
Does soot always mean the wick is too big?
No. Continuous soot from a tall, steady flame with a hot jar does mean over-wicking. But intermittent, puffing soot from a small flame usually means the opposite — a partially drowned wick or a mushroom head shedding unburnt carbon — and soot also appears with a correctly sized wick when the fragrance load is at the wax maker's stated ceiling or the dye is heavy. Trim to 5 mm, relight in a closed room, and check flame height at twenty minutes. Then burn an unscented control jar with the same wick to separate the formula from the wick.
How long should a candle take to reach a full melt pool?
Two to three hours is the target for a single-wick container candle. Three to four hours is borderline and acceptable in a wide jar. Beyond four hours the candle will never open its pool in normal use, because four hours is where a single burn should end — it will build a memory ring and tunnel instead. The full timing guide is here, and why isn't my candle creating a full melt pool covers the causes.
Why does the same wick work in one jar and not another?
Because pool area grows with the square of the radius. A 60 mm jar has a full pool of about 28.3 cm² and a 70 mm jar about 38.5 cm² — 36% more surface for the same flame to keep molten, from what looks like a small change in diameter. Any wick has to be re-validated in every container you pour into, and a wax change counts as a new test too. Diameter-by-diameter starting points are in the wick guide by diameter.
What does a three-jar wick test cost at CSI?
₹367.80 for the wicks: Eco Candle Wicks Thin (C1) at ₹59.00 for 10 and Thick (C2) at ₹188.80 for 20, plus Cotton Braided Wicks at ₹120.00 for 10. Add a pack of five identical White Matte Glass Jars at ₹354.00 and a Wick Centering Device pack of 5 at ₹118.00 and the whole rig is ₹839.80. Time one burn first — if the fault turns out to be a short first burn or a draught, none of that is needed.

Non-price figures: Melt-pool areas are calculated as A = πr² from nominal internal diameters and are geometry, not measurements: 45 mm = 15.9 cm², 50 mm = 19.6 cm², 55 mm = 23.8 cm², 60 mm = 28.3 cm², 65 mm = 33.2 cm², 70 mm = 38.5 cm², 75 mm = 44.2 cm², 80 mm = 50.3 cm², 90 mm = 63.6 cm². Time-to-full-pool bands (under 2 hours over-wicked, 2–3 hours target, over 4 hours under-wicked), pool depth of 6–13 mm, flame height of roughly 25–40 mm and the four-hour maximum single burn are standard container-candle working thresholds, not laboratory results — verify them on your own bench. Fragrance load ceilings of up to 13% for Luxury Soy Wax Chunks and up to 10% for Luxury Soy Wax CSI 464 are the wax manufacturers' stated formulation maximums, not regulatory limits.
