The short answer: A quality soy or coconut soy candle burns approximately 6–8 hours per ounce of wax. An 8 oz candle lasts 45–55 hours. A 10 oz candle lasts 55–65 hours. Burn time varies significantly by wax type, wick size, and how well you care for the candle.
Candle Burn Time by Size, Quick Reference Table
| Candle Size | Wax Type | Estimated Burn Time |
|---|---|---|
| 4 oz | Coconut soy | 25–35 hours |
| 6 oz | Coconut soy | 35–45 hours |
| 8 oz | Coconut soy | 45–55 hours |
| 10 oz | Coconut soy | 55–65 hours |
| 12 oz | Coconut soy | 65–80 hours |
| 4 oz | Paraffin | 20–25 hours |
| 8 oz | Paraffin | 30–40 hours |
| 8 oz | Pure soy | 40–50 hours |
| 8 oz | Beeswax | 50–60 hours |
| Taper candle (10 inch) | Paraffin | 8–10 hours |
| Tealight | Paraffin or soy | 3–5 hours |
| Votive (2 oz) | Soy | 10–15 hours |
Note: These are estimates. Actual burn time depends on wick size, fragrance load, room temperature, and how you burn the candle.
How Long Should You Burn a Candle in One Session?
Never burn a candle for more than 4 hours at a time. After 4 hours:
- The wick begins to “mushroom” (the carbon tip enlarges), causing soot and uneven burning
- The jar heats up enough to become a burn risk
- Fragrance throw often weakens past the 4-hour mark anyway
The ideal burn session: 2–4 hours. This is long enough for the melt pool to fully form and the fragrance to fill a room, but short enough to protect the wick and wax quality.
After extinguishing, let the candle cool completely (at least 2 hours) before relighting.
Burn Time by Wax Type: Why It Matters
The wax your candle is made from has the single biggest impact on how long it lasts.
| Wax Type | Burn Rate | Scent Throw | Notes |
|---|---|---|---|
| Coconut soy blend | Slowest | Excellent | Premium burn; best fragrance retention |
| Pure soy | Slow | Good | Clean burn; widely available |
| Beeswax | Slow | Mild (natural honey scent) | Longest burn per oz; limited fragrance options |
| Paraffin | Fast | Strong cold throw, weaker hot | Most common; shorter life |
| Coconut apricot | Slow | Very good | Creamy texture; excellent for jar candles |
Coconut soy candles, like all Gist of Light candles, burn slower and longer than paraffin because the wax has a lower melt point. The fragrance releases gradually and consistently, meaning you get the full scent experience throughout the burn rather than a strong opening followed by a flat finish.
What Shortens a Candle’s Life? (And How to Avoid It)
1. Skipping the first burn rule
The most common reason candles die early is tunnelling, when the wax burns down the centre without melting to the edges. This happens when the first burn is cut short.
On the very first burn, let your candle burn until the entire surface has melted edge-to-edge. For an 8 oz candle, this takes approximately 2–3 hours. Soy and coconut soy wax have a “burn memory”; the wax will only ever melt as far as it did on the first burn.

2. Not trimming the wick
An untrimmed wick burns hotter and faster, consuming wax more quickly and producing soot. Trim to ¼ inch (6mm) before every single burn. This one habit alone can add 15–20% to your candle’s total burn life.
3. Burning in a draught
Air movement, from a fan, an open window, or an air vent, causes the flame to flicker and burn unevenly. This wastes wax on one side of the jar and shortens burn time. Always burn candles away from direct airflow.
4. Burning past the ¼ inch wax mark
When ¼ inch of wax remains in the jar, stop burning. The jar heats up dangerously when there’s not enough wax to absorb heat, and the fragrance has typically been exhausted by this point anyway.
How Long Should Specific Candle Sizes Last (Real-World Use)?
Assuming 3-hour burn sessions, 4–5 times per week:
| Candle Size | Burn Time | Sessions | Real-World Duration |
|---|---|---|---|
| 8 oz coconut soy | 45–55 hours | ~17 sessions | 3–4 weeks |
| 10 oz coconut soy | 55–65 hours | ~20 sessions | 4–5 weeks |
| 12 oz coconut soy | 65–80 hours | ~25 sessions | 5–6 weeks |
If you burn more casually, once or twice a week, an 8 oz candle can easily last 2–3 months.
How long does a wax burn last vs. how long does the scent last?
These are two different questions. A candle can still have wax remaining after the fragrance has faded. This happens when:
- The fragrance load was low (cheap candles often use less fragrance oil to cut costs)
- The wick was too large, burning through the fragrance oil too quickly
- The candle was burned in very long sessions without breaks
With high-quality coconut soy candles using a proper fragrance load (typically 8–10% by weight), the scent should last through the candle’s full burn life.
At Gist of Light, every candle is tested for scent throw from the first hour to the final burn before a fragrance is approved for production.
Do Candles Expire? Shelf Life Before You Ever Light Them
Here’s the part most burn-time guides skip: candles have two lifespans. Burn time is one. The other is shelf life, how long a candle keeps its fragrance while sitting unlit in a cupboard.
Candles don’t “go bad” the way food does. As long as there’s wax and a wick, an old candle will still light. But fragrance oils slowly evaporate, even through a sealed lid, and the scent throw weakens over time.
| Candle Type | Best Used Within | Notes |
|---|---|---|
| Scented (coconut soy / soy) | 12–18 months | Fragrance strongest in the first year |
| Scented (paraffin) | 1–2 years | Holds scent slightly longer, burns dirtier |
| Unscented | Indefinite | Emergency-kit staple for a reason |
Storage makes the difference. Keep unlit candles in a cool, dark, dry place with the lid on. Heat and sunlight speed up fragrance evaporation and can fade the wax colour; a windowsill is the worst place to store a candle you’re saving.
And yes, you can burn a 10-year-old candle safely. It just probably won’t smell like much.
Burn Time by Candle Type
| Candle Type | Typical Burn Time |
|---|---|
| Tea light | 3–5 hours |
| Votive | 10–15 hours |
| Taper | 8–12 hours (roughly 1 inch per hour) |
| 8 oz jar (coconut soy) | 45–55 hours |
| Large jar / pillar | 50–150 hours |
| Wax melt (per cube) | 6–10 hours in a warmer |
The 3–4 Hour Rule
Whatever the size, don’t burn a candle for more than about 4 hours at a time. Past that point, the wick “mushroom” forms a carbon ball on the tip, the flame grows unstable, and the candle starts consuming wax faster while producing soot. Extinguish, cool, trim, relight. Your total burn hours go up, not down.
Frequently Asked Questions
How long do soy candles burn compared to paraffin?
Soy candles typically burn 30–50% longer than paraffin candles of the same size. An 8 oz paraffin candle might last 30–40 hours; a soy or coconut soy equivalent lasts 45–55 hours.
How long should I burn a candle the first time?
Until the melt pool reaches the full edges of the jar, which typically takes 2–3 hours for an 8 oz candle. Never cut the first burn short.
How long can you leave a candle burning safely?
Maximum 4 hours in a single session. After 4 hours, extinguish, let cool completely, trim the wick, and relight.
How long does a taper candle burn?
A standard 10-inch taper candle burns for approximately 8–10 hours, at roughly 1 inch per hour.
Why does my candle not last as long as it says on the label?
Usually because of tunnelling (first burn was too short), an untrimmed wick (burning too hot), or burning in a draught. Follow the care guide above, and you’ll reach or exceed the stated burn time.
