Wick trimming is the single most impactful candle care habit you can build, yet most people never do it. Here is everything you need to know.
Why does wick length matter?
The wick controls how much fuel (liquid wax) reaches the flame. A wick that is too long draws up more wax than the flame can cleanly combust, resulting in:
- Soot and black smoke that deposits on your vessel and walls
- A large, unstable flame that is a fire hazard
- Faster wax consumption, so your candle burns out sooner
- Reduced fragrance throw, as the scent burns off too quickly
A correctly trimmed wick produces a steady, controlled flame roughly 2 to 3cm tall.
How short should you trim a candle wick?
Trim to 5mm (1/4 inch) before every burn. This applies to:
- The very first burn on a new candle
- Every subsequent relight, even if you burned it yesterday
Step-by-step: how to trim a candle wick
- Let the candle cool completely before trimming. Never trim a wick while the wax is liquid.
- Use wick trimmers or small scissors. Nail scissors work well for deep vessels.
- Cut to 5mm above the wax surface and remove any mushroomed carbon buildup at the tip.
- Remove the trimmed piece. Do not leave clippings in the wax, as they can reignite.
- Check the wick is centred and gently reposition if needed before lighting.
What if the wick is too short?
If you have trimmed too aggressively (below 3mm), the candle may struggle to stay lit or the flame may drown in the melt pool. In this case, carefully pour off a small amount of liquid wax once the candle has been burning for 20 to 30 minutes to expose more wick.
What tools do you need?
A dedicated pair of wick trimmers is worth the small investment. Their angled head reaches into deep vessels easily and catches the trimmed piece so it does not fall into the wax. Standard scissors are a perfectly good alternative for shallower candles.
