🕯️ Burn Time Calculator
Enter your candle's wax weight and type to estimate how many hours it will burn — handy for pricing, product listings, and setting customer expectations.
🧮 Estimate Burn Hours
What is a Burn Time Calculator?
It turns a candle's wax weight into an estimated number of burn hours using a typical burn rate for its format. Container and pillar candles burn at roughly 7 hours per ounce; smaller votives and tealights nearer 8, since they burn a little more slowly relative to their size.
Use it to describe a product accurately, compare candle sizes, and plan how long a batch of gifts or stock will last. Real-world burn time depends on the wick, fragrance, and burning habits, so publish it as an estimate.
❓ Frequently Asked Questions
How long will my candle burn?
Burn time scales with how much wax the candle holds. A common maker's estimate is roughly 7 hours per ounce of wax for container and pillar candles, and about 8 hours per ounce for smaller votives and tealights. Enter your wax weight and candle type for a quick total.
What affects a candle's actual burn time?
Wick size, fragrance load, wax blend, and — most of all — how the candle is burned. Long unbroken burns, drafts, and an untrimmed wick all change the rate, so treat the estimate as a planning figure rather than a promise.
How can I make my candle last longer?
Trim the wick to about 1/4 inch before every burn, let a full melt pool form on the first burn to prevent tunnelling, keep candles out of drafts, and avoid marathon sessions — burning in blocks of a few hours preserves the wax and the wick.
How long should each burn session be?
Keep sessions to around 4 hours at most. Longer burns overheat the container and the wick, cause carbon build-up and mushrooming, and shorten the candle's overall life. Always extinguish before leaving and never leave a burning candle unattended.
