# How Long Do Candles Last? Burn Time, Shelf Life and What Affects Both Source: https://candlemakingnest.com/blog/how-long-do-candles-last Published: 2026-10-28 Publisher: Candle Making Nest How long a candle lasts has two answers: how many hours it burns, and how long it stays good on a shelf. Burn time depends mainly on the amount of wax, the wick size, the wax type and how you burn it. Shelf life depends on storage, because heat, light and air change the scent and appearance over time. Labels usually give an estimated burn time, but real results vary. This article explains the factors, how to get more hours from a candle and how to store candles so they stay in good condition. ## Burn time on the label and in real life Burn time on a label is normally an estimate based on the weight of the wax and the testing the maker did. It is often a continuous burn in a draft-free room, which differs from how most people use candles. Real-world burn time depends on how often you light the candle and for how long each time. As a loose guide, a candle with more wax lasts longer, but the same weight can burn faster or slower depending on the wick. If you make your own candles, you can measure burn time yourself by weighing the candle before and after each burn session. ## What affects how fast a candle burns The wick is the biggest factor. A large wick draws more wax and burns faster, while a small wick burns slowly but may tunnel. The wax type matters too. Harder waxes with higher melt points generally burn more slowly than soft waxes. Fragrance load, dye and additives also play a role. Drafts, room temperature and the container affect the burn. A candle placed in a draft flickers, burns unevenly and may use wax faster. A wide jar burns more wax per hour than a narrow one with the same wick.

A long wick produces a larger flame, soot and faster consumption. Let the melt pool reach the edge of the container on the first burn, which usually takes a couple of hours, so the candle does not tunnel and waste wax. Avoid burning a candle for very long sessions. Many makers suggest stopping after a few hours, letting the candle cool and trimming before relighting. Keep it away from drafts, and do not burn the last half inch of wax, as the glass can overheat.

Fragrance oils fade over time, wax can develop a dusty bloom or frosting and colors can shift when exposed to light. Suppliers often suggest using candles within a year or two for the best scent, though this varies by wax and fragrance. There is no universal expiry date. Smell and look at a candle before burning it. If the scent is weak, the wax has discolored or the surface has changed, it can still be burned in many cases, though the experience may be less pleasant. ## How to store candles Keep candles in a cool, dry place away from direct sunlight and heat sources. Lids protect against dust and help hold scent. Avoid storing candles in attics or cars where temperatures can swing, since high heat can soften the wax or cause it to leak or sweat. Store candles upright, avoid stacking heavy items on them and wrap taper candles flat to prevent bending. For stock you plan to sell, record the date of pouring and keep some for future test burns.

Divide grams lost by minutes to get a burn rate, then use that to estimate how long a full candle should last. Repeat on a few candles, since individual results vary. A consistent rate is a good sign that the wick suits the wax and vessel. A rate that changes a lot between sessions suggests drafts, wick length differences or a recipe that needs adjusting.

These changes are mostly cosmetic. A white bloom on a soy candle is known as frosting and does not affect how it burns, though it can look unappealing. If you see mold-like spots, a rancid smell or a damaged wick, discard the candle. Otherwise, a trim of the wick and a short test burn will show whether it still performs as expected.

Tealights and votives burn for a shorter, fixed period. Wax melts are not burned at all but warmed, and their scent lasts for a number of hours that depends on the warmer and the fragrance. Comparing hours across types is difficult, because candle sizes, wicks and waxes differ. Use label estimates as a rough guide only, and compare candles of the same type when deciding which lasts longer for your needs. If you sell candles, avoid promising a specific number of hours unless you have measured it. Say 'up to' and describe how you tested.

Place them on a heat-safe surface and extinguish them if the flame becomes very large or the container gets extremely hot. If you notice unusual smoke, cracks in the glass or a flame that will not settle, put the candle out safely and stop using it. ## Related buying guides - https://candlemakingnest.com/best/best-candle-testing-supplies - https://candlemakingnest.com/best/best-wick-trimmers - https://candlemakingnest.com/best/best-jar-lids - https://candlemakingnest.com/best/best-candle-care-cards
