Candles are a great way to add ambiance to a room, with their soft glow, subtle fragrance, and warm atmosphere. But how long do they last? The answer depends on several factors, including the size of the candle, the type of wax used, the number of wicks, and how often you burn it. For example, paraffin wax candles tend to have longer burn times than soy or beeswax candles, and larger candles with more wicks will also last longer. On average, a candle should be burned for around 2-4 hours at a time, and with proper care, it can be preserved for a long time.
| Characteristics | Values |
|---|---|
| Average burn time | 2-4 hours at a time |
| Burn time factors | Size of the candle, type of wax, number of wicks, movement of air in the environment, amount of oxygen available, surrounding temperature, material of the wick |
| Candle longevity | Depends on the type of candle; Paraffin and beeswax candles can last indefinitely if stored correctly, while soy candles are best used within a year or two |
| Scent longevity | Scent degradation occurs very gradually, almost unnoticeable for the first 6 months to a year, depending on the type of wax and quality of fragrance oils used |
| Colour longevity | Depends on the amount and type of light exposure; store in a dark place to prevent colour fading |
| Storage | Store in a cool, dry place away from direct sunlight and other harsh lights |
| Extending longevity | Use a candle topper or a glass cloche to preserve the fragrance, burn for at least 2 hours at a time to prevent tunnelling, trim the wick to 1/4 inch, use a candle snuffer to extinguish |

What You'll Learn
Candle burn time varies
The number of hours a candle stays lit and emits fragrance is known as its "burn time." While candles don't technically expire, their colour and scent can fade over time, and it is recommended to use them within the first six months to a year of purchase. To extend the life of a candle, it should be stored in a cool, dark place, away from direct sunlight and other harsh lights, as UV light can cause the dyes in the wax to degrade.
The number of wicks in a candle also affects its burn time. Candles with multiple wicks will burn faster and have a shorter overall burn time than those with a single wick. Additionally, the material of the wick can impact the burn time, with certain materials burning slower or faster than others. Trimming the wick to between 1/8 and 1/4 of an inch before lighting can help prolong the life of the candle and improve its performance by preventing uneven burning, dripping, and sooting.
The type of wax used in a candle also influences its burn time. Candles made from paraffin wax, a petroleum-derived product, tend to have longer burn times due to the high melting point of the wax. However, paraffin wax is not renewable and releases toxic chemicals when burned. Beeswax, on the other hand, burns slowly and smoothly but is not ideal for holding fragrance. Natural and renewable wax blends are also available, which can hold and release fragrance more effectively than paraffin wax while burning cleaner.

Candle storage
While candles don't technically expire, their lifetime depends on the type of wax used and how they're stored. Paraffin candles, for example, can last almost indefinitely when stored properly, while soy candles are best used within one or two years.
To extend the life of your candles, there are several steps you can take. Firstly, avoid storing them in areas with direct sunlight or harsh indoor lighting, as UV rays can cause the dyes in the wax to oxidize and degrade, resulting in colour fading. Instead, opt for a dark and cool storage space, such as a cupboard or shelf away from windows or sources of artificial light.
It's also important to maintain a stable environment for your candles by avoiding areas with high humidity, moisture, or sudden changes in temperature. Bathrooms, radiators, and vents are therefore not ideal storage locations. Additionally, ensure your candles are stored away from flammable materials and any potential sources of ignition.
To preserve the fragrance of your scented candles for longer, consider using a candle topper or a glass cloche. Trimming the wick before lighting can also make a significant difference in the candle's burn time, with candles burning up to 25% longer if the wick is trimmed every couple of hours.
Lastly, while candles can be stored for extended periods, it is generally recommended to burn them within a year of purchase for the best experience, as scent degradation can occur over time, even in stored candles.

How to make candles last longer
The burn time of a candle depends on its size, the type of wax used, the number of wicks, and the surrounding environment. To make your candles last longer, there are several steps you can take:
Storage
Store candles in a cool, dry, and dark place, away from direct sunlight and heat sources. Avoid areas with high humidity and moisture, or sudden changes in temperature. Exposure to light and heat can cause discolouration and weaken the scent. Keep the candles covered with a lid or a glass cloche to preserve the fragrance for longer.
Trimming the wick
Before lighting the candle, trim the wick to about 1/4 inch. This helps prevent large flames, sooty smoke, and uneven burning. It also helps prolong the life of your candle by up to 25%.
Burn time
Limit each burn session to around 3-4 hours. Burning a candle for too long can cause the wick to "mushroom", resulting in a larger flame, soot, and excessive heat. Allow the candle to cool for at least 2 hours before relighting.
Remove debris
Keep the wax pool free of debris like wick trimmings, matches, or dust. These can act as secondary wicks, leading to uneven burning and unsafe conditions.
Avoid drafts
Place the candle away from areas with strong currents of air, such as fans, open windows, or crowded areas. Air currents can cause uneven burning and reduce the lifespan of the candle.
Alternate candles
Don't leave a candle unattended for too long. Alternate between candles to prolong their burn time.

Different types of candles, different burn times
Candles don't technically expire, but their lifespan depends on the type of wax used and how they're stored. For instance, paraffin candles can last almost indefinitely when stored properly, while soy candles are best used within a year or two.
The burn time of a candle is influenced by factors such as the size of the candle, the type of wax, the number of wicks, the movement of air in the environment, the amount of oxygen available, the surrounding temperature, and even the material of the wick.
- Paraffin wax candles: Paraffin wax is the most common type of candle wax. It is derived from petroleum and tends to be inexpensive. While it is not a renewable resource, it can deliver an intense fragrance. Paraffin wax candles filled with synthetic additives and preservatives will essentially never go bad, but they may release toxic chemicals when burned.
- Beeswax candles: These candles are made from beeswax, which burns slowly and smoothly. However, beeswax is not ideal for holding fragrance.
- Soy wax candles: Soy wax candles are a natural alternative to paraffin wax. They burn cleaner and slower, without releasing toxic chemicals. However, they may not last as long as paraffin wax candles.
- Luxury candles: Luxury candles, such as those from the Harlem Candle Company, often have longer burn times due to their larger size and high-quality wax. A 12 oz luxury candle from this company has an average burn time of approximately 80 hours.
To get the most out of your candles, it is recommended to trim the wicks before lighting them and to burn them for no more than 4 hours at a time. It is also important to store candles in a cool, dark place away from direct sunlight and other sources of light, as UV rays can cause the colour to fade over time.

When to throw away a candle
The average burn time of a candle depends on several factors, including its size, material, and how it is burned. Generally, larger candles with more wax will last longer than smaller candles. Paraffin wax candles tend to have longer burn times than soy or beeswax candles.
When it comes to deciding when to throw away a candle, there are a few things to consider. Firstly, it is recommended to limit each candle to a burn time of 2 hours, but no more than 4 hours at a time. This helps prevent excessive smoke, uneven burns, and wasted wax. Allowing the wax to melt completely to the edges of the vessel during the first burn can also help extend the life of the candle.
Some people choose to burn their candles until the wick is completely spent and cannot be lit anymore. At this point, the remaining wax can be used in a wax warmer or repurposed into a new candle. Others may choose to discard their candle when only a half inch of wax remains, as burning it longer can create a safety hazard.
Additionally, it is important to store candles properly to extend their lifespan. They should be kept in a cool, dry place away from direct sunlight and drafts. Following these tips can help ensure that your candles last as long as possible.
Lastly, it is worth noting that while candles do not technically expire, their fragrance may fade over time. However, this can be mitigated by following the tips mentioned above and choosing higher-quality candles made with natural and renewable waxes, which tend to burn cleaner and have better scent throw.
