How Long Does a Candle Last? Burn Time by Size, Wax, and Wick Count
Jul
Candle Basics
How long does a candle last? Burn time ranges from a few hours for a tea light to well over a hundred for a large single-wick jar, and size, wick count, and wax type all move the number.
Key takeaways
How long a candle lasts depends mostly on size and wick count. A single tea light burns about 4 to 6 hours, a 7 oz jar around 35 to 45 hours, and a 22 oz single-wick jar roughly 110 to 150 hours. Expect about 5 to 9 hours of burn time per ounce of wax.
- By size: a tea light lasts about 4 to 6 hours, a 22 oz single-wick jar about 110 to 150 hours.[6]
- By wick count: more wicks burn a jar faster, so a 3-wick 18 oz can finish in 30 to 50 hours.[6]
- Rule of thumb: roughly 5 to 9 hours of burn time per ounce of wax.[6]
- Longest life: trim the wick, cap sessions near 4 hours, and stop at the last half inch of wax.[2]
How long does a candle last once you light it? Burn time is not one number: it is a range set mostly by wax volume and wick count. A tea light might glow for 4 to 6 hours, while a 22 oz single-wick jar can run 110 to 150 hours.[6] This guide covers burn time when the candle is lit, which is a different question from wax life under a warmer, where the wax is melted but never consumed. For that second topic, see our guide to whether candle warmers make candles last longer.
The honest answer starts with a chart, then explains the mechanics. Wick count, wax type, first-burn habits, and wick trimming all push the total up or down. To keep this focused, we cover lit burn time only, and link out for how long wax melts last and for warmer questions.
01How Long Does a Candle Last by Size?
Size is the biggest driver of burn time: more wax means more fuel. Tea lights and votives last single-digit hours, while large jars reach the triple digits. The chart below collects typical figures for common sizes. These are not proprietary to any one brand: burn time follows the candle-industry method of measuring hours per ounce of wax,[1] which for most candles lands near 5 to 9 hours per ounce.[6]
Typical figures, about 5–9 hours of burn per ounce of wax; multi-wick (rust) burns a jar faster. Sources: BottleStore, The Flaming Candle (retrieved 2026-07-15).
| Candle size (oz) | Wick count | Typical burn time (hours) | Source |
|---|---|---|---|
| Tea light | 1 | 4 to 6 | [6] |
| Votive or sampler | 1 | Up to 15 | [6] |
| 1.3 (mini) | 1 | 7 to 10 | [6] |
| 4.3 (small) | 1 | 20 to 30 | [6] |
| 7 (regular) | 1 | 35 to 45 | [6] |
| 14.5 (medium jar) | 1 | 65 to 75 | [6] |
| 14.5 (multi-wick) | 3 | 25 to 45 | [6] |
| 18 (tumbler) | 3 | 30 to 50 | [6] |
| 20 (large jar) | 1 | 60 to 90 | [6] |
| 22 (large jar) | 1 | 110 to 150 | [6] |
| 22 (tumbler) | 2 | 75 to 110 | [6] |
Read the ranges, not the midpoints. A 14.5 oz single-wick jar is rated 65 to 75 hours, yet a 14.5 oz three-wick jar of similar wax is often rated only 25 to 45 hours.[6] Same wax weight, very different totals, because the wick count changes how fast the wax is consumed. Drafts, wick trimming, and burn habits then shift each real result inside or below its printed range.
02Hours Per Ounce: A Rough Rule of Thumb
If your candle is not on the chart, estimate from its weight. A common industry rule of thumb is about 7 to 9 hours per ounce for small candles and 5 to 7 hours per ounce for larger ones, which puts a 12 oz jar near 60 to 84 hours.[6] These are planning numbers, not guarantees.
The per-ounce figure quietly assumes a single wick and careful burning. Single-wick jars typically run about 5 to 7 hours per ounce, while three-wick versions drop to roughly 2 to 3 hours per ounce.[6] Similar wax, very different totals: the gap is almost all wick count and burn discipline.
03What Is the 3 Hour Rule for Candles?
The 3 hour rule is a safety habit: do not burn a candle for more than about 3 to 4 hours in one session. The National Candle Association puts the ceiling at about four hours: extinguish, let the candle cool for a couple of hours, trim the wick, and only then relight.[3] Burning past that point lets the wick mushroom, the flame grow, and the glass overheat.
The first burn matters just as much as the ceiling. A widely repeated guideline is to burn about 1 hour for every 1 inch of container diameter, long enough for the top layer to melt from wall to wall.[4] Stop too soon and the wax forms a memory ring that makes the candle tunnel down the middle on later burns, wasting wax and cutting usable life. A 3 inch wide jar therefore wants about a 3 hour first session.
04How Long Do Scented Candles Last Once Lit?
How long do scented candles last once lit? The wax and the fragrance run on two different clocks. The wax burns on the chart’s schedule, but scent often fades earlier, because fragrance oils evaporate from the melt pool faster than the wax disappears. Many people notice a weaker throw in the final third of a jar while plenty of wax remains.
This is where lit burn time ends and a different question begins. Sitting unlit on a warmer, the wax melts but never burns as fuel, so it can release scent long after it would have burned away. That is a wax-life question, not a burn-time one, and we handle it in the guide on whether candle warmers make candles last longer. Here we stay with the lit flame.
05Do More Wicks Mean a Shorter Candle Life?
Yes, more wicks almost always shorten total burn time for a given wax weight. Each extra flame consumes wax faster, so a multi-wick candle trades longevity for a bigger melt pool and a stronger opening throw. That is why a 22 oz single-wick jar is rated 110 to 150 hours, while a 22 oz twin-wick tumbler of similar wax drops to 75 to 110 hours.[6]
The three-wick penalty is steeper. An 18 oz three-wick tumbler is rated just 30 to 50 hours, close to a plain 7 oz single-wick jar despite holding far more wax.[6] Multi-wick candles are not defective; they are tuned to fill a room quickly. If maximum hours matter more to you than instant throw, a single wick usually wins.
Single wick
- Melts a smaller, calmer pool
- Consumes wax slowly for maximum hours
- Best for long, quiet burns
- Softer opening scent throw
Multiple wicks
- Fills a room fast with strong throw
- Consumes wax more quickly
- Fewer total hours per ounce
- Best only when speed beats longevity
06Does Wax Type Change Burn Time?
Wax type matters, but less than size or wick count, and its effect is often overstated. The common industry claim is that soy wax burns slower and cooler than paraffin, so a soy candle of the same size may last somewhat longer. We treat that as a general, directional statement rather than a fixed percentage, because there is no rigorous, apples-to-apples public figure for the difference.
Formula details swamp the wax family. Fragrance load, additives, wick size, and jar shape can move burn time more than the base wax does. Beeswax is dense and long-burning, paraffin formulates well for strong throw, and soy sits between, yet a well-made paraffin candle can outlast a poorly made soy one. Judge the specific candle, not the wax label.
07Why Nominal and Real Burn Times Differ
Printed burn times are laboratory-style estimates, and your real total is often shorter. Manufacturers measure under steady, draft-free conditions with a freshly trimmed wick. Votives and tea lights show the gap most clearly: a tea light is sold as a 4 to 6 hour candle and a votive as up to 15 hours, yet both often finish sooner in a breezy room or near a vent.[6]
Three habits reclaim the printed range. Trim the wick to about a quarter inch before each burn, keep the flame away from drafts, and let a full melt pool of about a quarter to half inch depth form on the first session.[5] The National Candle Association also advises stopping when about a half inch of wax remains, both for safety and because the last sliver rarely burns cleanly.[2] Skip these and even a generous rating underdelivers.
08How to Make a Candle Last Longer
Getting the most hours out of a candle is mostly about the first burn and steady maintenance. The single highest-value habit is a proper first burn: let the melt pool reach the edge so the candle never starts tunneling. After that, trim, cap your session length, and stop before the base overheats.
Burn a full first pool
Let the top melt from wall to wall on burn one, about 1 hour per inch of diameter, forming a pool near a quarter to half inch deep.[4]
Trim before every burn
Cut the wick to about a quarter inch to control flame size and soot.[2]
Cap each session near 4 hours
Extinguish, let it cool, and retrim before relighting.[3]
Stop at the last half inch
Retire the candle when about a half inch of wax is left.[2]
None of this defeats the two clocks: fragrance eventually thins while wax remains. Some people then move the leftover jar onto a warmer, which melts wax without burning it. If you are weighing a flame against flame-free warmth, our candle warmer versus candle comparison lays out the trade-offs, and safe spacing still applies: keep any lit candle at least 12 inches from anything flammable and 3 inches from the next candle.[2]

A short look at how size and wick count decide the hours, and how a warmer lamp sidesteps the four-hour session cap by melting the wax gently from above with no flame.
Frequently asked questions
These answers keep physical burn time separate from fragrance life and from wax life under a warmer. Size and wick count drive the hours; habits and conditions decide whether you reach them.
The visible FAQ and the FAQPage schema are rendered from one registry, so search systems receive the same wording that readers see.
What is the 3 hour rule for candles?
It is a safety habit of limiting each burn to roughly three to four hours, with most brands treating four hours as the ceiling. Longer sessions let the wick mushroom, the flame climb, and the container overheat. After you reach the limit, put the candle out, let it cool, trim the wick, and relight only when you are ready for another controlled session.
How long should a candle last per ounce of wax?
As a planning estimate, expect about 7 to 9 hours per ounce for small candles and 5 to 7 hours per ounce for larger ones. A 12 oz jar therefore lands near 60 to 84 hours. Multi-wick candles fall well below that, because each extra flame consumes wax faster, so treat per-ounce math as a single-wick guideline.
How long does a candle last indoors before the scent fades?
The scent usually fades before the wax runs out. Many candles smell strongest through the first half to two thirds of the jar, then throw more weakly even with plenty of wax left. Room size, ventilation, and how strong the fragrance was to begin with all shift the point where you stop noticing it, so there is no single indoor number.
Do bigger candles always burn longer?
Usually, but not always. More wax means more fuel, so a bigger candle tends to outlast a small one of the same style. Wick count can flip the result: a large three-wick candle may finish faster than a smaller single-wick jar, because three flames burn wax much more quickly. Compare wax weight and wick count together, not size alone.
How long do birthday candles last?
A standard thin birthday candle burns for only about 10 to 15 minutes — long enough to carry a cake to the table and sing, not long enough to leave alone. Taller numeral and long-burning party candles are usually rated closer to 30 minutes. They are the one format the hours-per-ounce rule does not fit: each holds barely a gram of wax and burns unshielded, so it disappears far faster per ounce than a jar candle. Never leave them lit unattended around children.
Can you make a candle last longer without burning it?
Yes. A candle warmer melts the wax with gentle heat instead of a flame, so the wax is not consumed and can release fragrance longer than burning would allow. That is a wax-life benefit rather than extra burn time. It also removes the open flame, though warmers still get hot and should be used according to their instructions.

Sources and evidence limits
Burn-time figures follow the candle-industry hours-per-ounce method and typical published ranges, not one brand’s catalog. Safety limits come from the National Candle Association. We use candle-supply and maker guidance only for first-burn and session habits, not as independent lab data. Birthday-candle timings are the one figure on this page taken from a printed package specification rather than the hours-per-ounce method: in a UK wholesale listing from Dawn Direct checked in August 2026, Belgian candle maker Spaas’s 6 mm by 60 mm combi birthday candle is rated at about 12 minutes of burn time, and printed times shift with candle diameter and wax type, which is why we give a range instead of a single number.
URLs were checked on July 15, 2026. Printed burn times are estimates measured under controlled conditions, so real results vary with wick trimming, drafts, and burn habits. We found no rigorous public figure for the exact burn-time difference between soy and paraffin wax, so we describe that difference only in general terms.
