Why wick trimming matters and how to do it properly
If you've ever lit a candle and noticed a huge, flickering flame, black smoke or a little mushroom-shaped build-up on the end of the wick, it might be time for a trim.
Wick trimming is one of the simplest parts of candle care, but it's also one of the easiest things to forget.
The good news? It takes about 30 seconds and can make a big difference to how your candle burns.
So, if you're wondering how to trim a candle wick, how short it should be and when you should do it, here's everything you need to know.
Why does trimming your candle wick matter?
Every time you burn your candle, the wick is exposed to heat and flame. As it burns, the wick can become longer and develop a small build-up of carbonised material at the end.
If you keep burning it without trimming, you may notice a larger or less controlled flame.
Regular candle wick trimming helps keep the flame at a more manageable size and encourages a more consistent burn.
It can also help reduce excess soot and the black "mushroom" that can sometimes form at the top of the wick.
Think of it as giving your candle a tiny haircut.
How short should a candle wick be?
For most of our LoveTay candles, we recommend trimming your wick to approximately 5mm before each burn.
You don't want to cut it so short that the wick struggles to stay lit, but you also don't want a long wick creating a large flame.
Around 5mm is a great starting point.
If you're using a different candle brand, always check the manufacturer's specific candle-care instructions, as wick recommendations can vary depending on the candle's size, wax and wick type.
How to trim a candle wick properly
Don't worry — you don't need any fancy equipment.
Step 1: Let your candle cool
Always wait until your candle is completely cool and the wax has fully solidified before trimming the wick.
Trying to trim a hot wick can be messy and may disturb the wax.
Step 2: Remove the old wick debris
If there's a small black or mushroom-shaped piece sitting on top of the wick, remove it carefully.
You don't want loose wick trimmings sitting in your candle's wax.
Step 3: Trim to around 5mm
Using a wick trimmer, nail clippers or another suitable trimming tool, carefully cut the wick down to approximately 5mm.
Try to make a clean, even cut.
Step 4: Remove the trimming
Make sure the little piece you've cut off doesn't remain in the candle.
Remove it from the wax and dispose of it before lighting your candle.
Step 5: Light and enjoy
That's it!
Your candle is ready for another beautiful burn.
When should you trim your candle wick?
The easiest rule to remember is:
Trim your wick before every burn.
Once your candle has completely cooled, check the wick before lighting it again.
If it's looking longer than around 5mm or has developed a build-up on the end, give it a quick trim.
Making wick trimming part of your candle-lighting ritual means you're much less likely to forget.
Light. Trim. Enjoy. Repeat. 🤍
What happens if you don't trim your wick?
We've all been guilty of it — you've had a long day, you want to light your favourite candle and suddenly remembering to trim the wick feels like one more thing on your to-do list.
But skipping your wick trim can contribute to an uncontrolled or inconsistent flame.
You may notice:
- A larger flame
- More flickering
- Excess soot
- A mushroom-shaped wick
- An uneven burn
Regular wick trimming helps your candle maintain a more controlled flame and supports a better overall burn experience.
Does wick trimming help prevent candle tunnelling?
It can help, but wick trimming isn't the main solution to candle tunnelling.
Tunnelling generally occurs when a candle isn't allowed to burn long enough for the wax to melt evenly across the surface.
That's why proper candle care involves both wick trimming and correct burn times.
A tiny trim makes a big difference
Wick trimming might seem like a tiny detail, but it's one of the easiest ways to look after your candle.
It takes less than a minute, costs you nothing and can help your candle burn more consistently.
So before your next burn, grab your wick trimmer (or a pair of nail clippers), give your wick a little haircut and settle in.
Because the best candle moments start with good candle care.
