One of the most common questions candle lovers ask is: how long do soy candles burn? Whether you’re investing in a luxury jar candle or picking up a small gift set, burn time matters. After all, no one wants their favourite fragrance to disappear too quickly.
The good news? Soy candles are well known for their impressive burn time — often lasting significantly longer than traditional paraffin alternatives.
Why Soy Candles Burn Longer
Soy wax is made from hydrogenated soybean oil, which gives it a naturally lower melting point than paraffin wax. This lower melting temperature means soy candles burn cooler and slower.
A slower burn equals:
- More hours of fragrance
- Better value for money
- A more even melt pool
- Less wasted wax
Because soy wax liquefies gradually, it doesn’t “race through” the candle. Instead, it releases fragrance steadily and consistently, allowing you to enjoy the scent for longer.
Average Soy Candle Burn Times
Burn time depends largely on the size of the candle and the number of wicks used. While every brand differs slightly, here’s a general guide:
- Mini (70–100g): 15–25 hours
- Standard (180–220g): 35–45 hours
- Large (300g+): 50–70+ hours
- Twin Wick Candles: Often around 40–60 hours depending on size
The quality of the wax blend, wick type, and fragrance load also influence performance. High-quality soy candles with well-balanced formulations typically outperform cheaper alternatives.
What Affects Burn Time?
Even the best soy candle won’t reach its full potential without proper care. Here are the key factors that impact how long your candle lasts:
1. Wick Maintenance
Trim the wick to around 5mm before each burn. A wick that’s too long creates a larger flame, which burns wax faster and can produce soot.
2. First Burn Matters
Allow the candle to melt all the way to the edges during its first use. This prevents “tunnelling,” where wax builds up around the sides and shortens the candle’s overall life.
3. Burn Duration
Aim to burn your candle for 2–4 hours at a time. Burning for only short periods can cause uneven melting, while excessively long burns may overheat the wax.
4. Environment
Drafts, fans, and open windows can cause uneven flames and faster burning. Keep candles in a stable, still environment for the best results.
Soy vs Paraffin: The Burn Time Difference
Compared to paraffin candles of the same size, soy candles generally last longer. Paraffin burns hotter and faster, which can mean a stronger initial scent throw but fewer total hours overall.
Soy candles, by contrast, offer a steady and prolonged fragrance experience. While they may cost slightly more upfront, their extended burn time often makes them the better long-term value.
The Bottom Line
So, how long do soy candles burn? On average, longer than you might expect — and longer than many traditional candles.
Thanks to their cooler, slower burn, soy candles provide extended fragrance, better efficiency, and a more enjoyable overall experience. With proper care, you can maximise every hour and make the most of your investment.
If you love candles that last beautifully through cosy evenings and special occasions alike, soy wax is a choice that truly goes the distance.
