Candles are a great way to add ambiance and fragrance to your home, but have you ever wondered how long they last? The lifespan of a candle depends on several factors, including its ingredients, size, shape, and how it's stored. Synthetic candles can be stored for years, while natural wax candles with essential oils should be used within 12 to 16 months for the best scent and burn. Proper candle care, such as trimming the wick and avoiding long burn times, can also extend the life of your candle. With so many variables, it's hard to give an exact answer, but understanding these factors will help you make the most of your favourite candles.

What You'll Learn
Candle composition and burn time
The burn time of a candle depends on its composition, size, and environment.
Wax Type
The type of wax used in a candle affects its burn time. Paraffin wax candles, for example, tend to have longer burn times than soy or beeswax candles. Harder waxes may also burn longer than softer waxes. The melting point of the wax is also important—the higher the melting point, the longer the candle will take to melt, resulting in a longer burn time.
Size
Larger candles typically have longer burn times than smaller candles as they contain more wax and fuel for the flame.
Wick Size
The size of the wick can also impact burn time. A larger wick may burn faster than a smaller wick. If the wick is too large, the candle will burn very quickly. If it is too small, the candle won't burn all the way through, resulting in a "tunneled" effect. The ideal wick size is between an eighth and a quarter of an inch long.
Environment
The environment in which a candle is burned can also affect its burn time. For example, burning a candle in a drafty room can cause the flame to burn faster, as can warmer temperatures, which cause the wax to melt faster.
Storage and Lifespan
The lifespan of a candle depends on its composition. Candles with synthetic oils and ingredients can be stored for years, while those made with natural wax and essential oils may not last as long. Most candles last around 12 to 16 months when properly stored, and the scent and quality of the burn are best within this timeframe.

How to store candles
The lifespan of a candle depends on many factors, including its ingredients, size, shape, melting point, and type of wax. For example, a candle with synthetic oils can be stored for years, while candles made with natural wax and essential oils will not last as long.
Regardless of the ingredients, for the best scent and burn, it is recommended to use a candle within 12 to 16 months of purchase. If you plan to store a candle for longer, be sure to do so properly.
- Keep them in a cool, dark place, away from direct sunlight and other harsh lights.
- Avoid areas with high humidity or moisture, such as bathrooms.
- Avoid areas with sudden temperature changes, such as near radiators or vents.
- Use a candle topper or a glass cloche to help preserve the fragrance.
- Store candles in a dry place, as moisture can affect their performance.
- Keep the wick trimmed to between an eighth and a quarter of an inch long.
- Do not burn a candle for more than four hours at a time.
- Ensure the wax pool reaches the edge of the vessel on the first burn to aid in proper long-term candle care.

Wick maintenance
Trimming the Wick
Trimming the wick is crucial to the longevity of your candle. Before using a new candle, use a wick trimmer to trim the wick to between an eighth and a quarter of an inch long. This length ensures the candle burns at an optimal rate, preventing the wick from becoming unstable due to carbon build-up. If the wick is too short, it may struggle to hold a flame, while an overly long wick can cause excessive soot and an unstable flame.
Burning Guidelines
When lighting your candle for the first time, avoid trimming the wick unless it is excessively long. This allows the initial burn to create a large enough flame to melt the entire top surface of the candle. For subsequent burns, trim the wick before each use. Additionally, it is recommended to burn your candle for 3 to 4 hours during the first use to ensure the wax pool reaches the edge of the vessel, promoting even burning and proper long-term candle care.
Extinguishing the Flame
To extinguish the candle, consider using a wick dipper or a wick snuffer. A wick dipper is a bent tool used to dip the lit wick into the wax pool, extinguishing the flame. A wick snuffer is placed over the flame to deprive it of oxygen. These tools are safer than blowing out the candle, which can cause flying flaming ash.
Maintaining the Wax Pool
Keep the wax pool clear of wick trimmings, debris, and burnt matches. Always ensure you achieve a full melt pool, where the entire top layer of wax melts, to prevent tunnelling and promote even burning.
Storage and Safety
Cover your candle with a paper topper, lid, or cotton bag when it is cooled to prevent dust accumulation. Store the candle out of the reach of children and pets, and always place it on a stable, heat-resistant surface. Avoid drafts that can cause soot and uneven burning, and never leave a burning candle unattended.

Signs a candle has expired
The lifespan of a candle depends on factors such as the type of wax, the thickness of the candle, the size of the wick, and the burn habits of the user. On average, a candle can burn for approximately 5-7 hours per inch of its diameter. However, there are signs to look out for that indicate when a candle has expired and should no longer be used.
One clear sign is the appearance of discolouration or frosting on the candle wax. Over time, factors such as sunlight exposure, temperature fluctuations, or air contaminants can cause the wax to change colour or develop a cloudy, frosted appearance. While this doesn't affect the candle's performance, some people prefer the aesthetic of a consistent, smooth finish.
Another important sign is the condition of the wick. If the wick appears damaged, curled, or excessively sooty, it's a sign that the candle may not burn properly and could produce more smoke and soot than usual. An expired candle may also have a weakened or soft wax structure, making it unstable and prone to melting or warping.
Additionally, pay attention to the candle's scent. If it has lost its fragrance or developed an odd smell, it's likely past its prime. This is especially important for scented candles, as the fragrance is a key component of their appeal. An odd smell could indicate that the fragrance oils have broken down or become contaminated.
Finally, trust your instincts. If the candle doesn't burn evenly, produces excessive amounts of smoke, or seems to burn faster than usual, it's probably best to replace it. An expired candle may also struggle to stay lit or produce a weak, flickering flame, indicating that the wick or wax is no longer functioning optimally. Always ensure to follow candle care instructions and burn your candles safely.

How to make candles last longer
The lifespan of a candle depends on several factors, including its ingredients, shape, size, melting point, and the number of wicks. While candles made with synthetic ingredients can be stored for years, those made with natural wax and essential oils have a shorter lifespan.
Choose the Right Wax
Opt for candles made from premium paraffin or soy wax. These waxes are designed to burn for longer and emit a rich aroma. Organic, vegetable-based waxes like soy and coconut are more prone to breaking down over time, leading to wick clogging and difficulty in lighting.
Store Properly
Store your candles in a dark, cool, and dry place, away from direct sunlight and other harsh lights. Avoid areas with high humidity, sudden temperature changes, and ensure they are not exposed to UV rays.
Trim the Wick
Trim the wick to between an eighth and a quarter of an inch long before lighting a new candle is crucial. This helps prevent the build-up of carbon, which can cause the candle to smoke and release soot.
Control Burn Time
Avoid burning your candle for more than 3 to 4 hours at a time. Burning for shorter periods will help extend the candle's lifespan and prevent it from melting too quickly.
Monitor the Flame
Keep an eye on the candle's flame. If it becomes too high or starts to smoke, extinguish the candle, let it cool, and trim the wick. This will help prevent excessive melting and ensure a longer-lasting candle.
Use a Candle Warmer
If you're concerned about lighting the candle directly, consider using a candle warmer. This method will slowly release the fragrance without burning the wax, preserving the candle's lifespan.

Frequently asked questions
The lifespan of a candle depends on several factors, including its ingredients, size, shape, and type of wax. Candles with synthetic ingredients can be stored for years, while those made with natural wax and essential oils should be used within 12 to 16 months.
The melting point of the candle wax is an important factor in determining burn time. A higher melting point means a longer burn time. The size of the wick also matters – if it's too large, the candle will burn quickly, and if it's too small, it won't burn evenly.
Always trim the wick to between an eighth and a quarter of an inch before lighting a new candle. Avoid burning a candle for more than 4 hours at a time to prevent carbon buildup on the wick. Store candles in a cool, dark place, away from direct sunlight and moisture.
An expired candle may smell more like wax than its intended scent. The wick may struggle to hold a flame, and the wax may appear discoloured due to UV exposure.
Scented candles generally retain their fragrance for 6 to 12 months. To get the most out of your candle, burn it for 3-4 hours on the first use to ensure an even melt pool. Store scented candles in a dark, cool place, as light and heat can cause the fragrance to degrade faster.
