How long should a candle burn? Candle burn time is one of the most important things to consider when choosing a luxury candle — and it varies significantly depending on five key factors. Understanding them helps you get the most from every Thompson Ferrier candle you own.
1. Wax Type
The type of wax used in a candle greatly impacts its burn time. The most common types include paraffin, soy, beeswax, and coconut wax. Natural waxes like soy, beeswax, and coconut wax generally burn more slowly than paraffin wax, resulting in a longer burn time. Soy candles tend to burn 30–50% longer than paraffin candles, while beeswax candles can burn even longer. However, paraffin wax diffuses fragrance more efficiently — which is why it remains the preferred wax for high-performance luxury candles.
2. Wick Material and Size
The wick is the heart of any candle, and its material and size significantly influence burn time. Cotton wicks are the most common and are known for their clean, consistent burn. Wooden wicks produce a soothing crackling sound and are often used in luxury candles. The size of the wick matters equally — a larger wick consumes more wax and can shorten the overall burn time. Trimming the wick to ¼ inch before every burn is the single most effective way to extend candle life and maintain a clean flame.
3. Candle Size and Shape
Larger candles with more wax will burn longer, while smaller candles have shorter burn times. The shape of the candle also matters — irregularly shaped candles may burn unevenly and affect overall performance. For the longest burn time, choose a full-sized vessel and follow proper burning practices from the first use.
4. Fragrance Load and Additives
The type and concentration of fragrance oils in a scented candle can affect burn time. Heavily scented candles — like Thompson Ferrier candles, which carry a 16–18% fragrance load — may burn slightly faster than lightly fragranced candles, as fragrance oil acts as additional fuel for the flame. Additives like colorants or hardening agents can also alter how the wax melts and burns. This is why proper wick trimming and burn cycle management are especially important for high-fragrance candles.
5. Burning Environment
The environment in which a candle is burned affects how quickly it burns. Drafts cause uneven burning and a shorter burn time. Room temperature and humidity affect the melting point of the wax and alter the burn rate. Always burn Thompson Ferrier candles in a still environment, away from open windows, fans, and air conditioning vents, on a stable heat-resistant surface.
The next time you light a candle, take a moment to appreciate the many factors that contribute to its burn time. Understanding these elements helps you make better-informed decisions and ensures you get the most from every candle you own.

Quick Answers: Candle Burn Times
How long should a luxury candle burn?
Burn time varies by candle size, wax type, and fragrance load. As a general rule, burn your candle for approximately one hour per inch of its diameter per session. Always allow the wax pool to reach the full edge of the vessel before extinguishing — and never burn for more than 4 hours at a time.
What wax type gives the longest burn time?
Beeswax and soy wax generally burn longer than paraffin wax. Soy candles typically burn 30–50% longer than paraffin candles. However, paraffin wax diffuses fragrance more efficiently, which is why it is preferred for high-performance luxury candles where scent throw is the priority.
Does a higher fragrance load shorten burn time?
Yes, slightly. Fragrance oil acts as additional fuel for the flame, so candles with a high fragrance load — like Thompson Ferrier’s 16–18% — may burn a little faster than lightly fragranced candles. Proper wick trimming and burn cycle management offset this and ensure the best possible performance.
How do I make my candle last longer?
Trim the wick to ¼ inch before every burn, allow the wax pool to reach the full edge of the vessel on each use, burn in cycles of no more than 4 hours, keep the candle away from drafts, and stop burning when ½ inch of wax remains at the bottom.
