There’s nothing quite like a candle to make a room feel cosy. But with an open flame comes a bit of responsibility, and a few simple habits make all the difference. Whether it’s trimming the wick, picking the right holder, or knowing when to call it a night, getting candle safety right is easier than you’d think.
At a glance
- Trim your wick to around 6mm before every burn
- Never leave a lit candle unattended, and keep candles away from children, pets, and anything flammable
- Use a proper heat-resistant holder on a flat, stable surface
- Don’t burn for more than 2–4 hours at a stretch, and get in the habit of extinguishing with a snuffer, not a puff of breath
Prepare your candle before lighting
A little prep goes a long way. Before you strike a match:
Trim the wick. Keep it to around 6mm, about the width of your thumbnail. A longer wick means a bigger flame, more smoke, and a faster burn. A wick trimmer is handy, but scissors do the job fine.
Pick the right spot. Flat surface, heat-resistant material. Think ceramic, glass, or stone; not the edge of a wooden shelf or anywhere near curtains. If it could catch fire, keep the candle away from it.
Check the candle itself. If it’s in a glass container, give it a quick look before lighting. Cracks or chips can cause the glass to break once it heats up, not ideal.
Burning candles safely
Candle lit? Lovely. Here’s how to keep things safe while it’s going:
Don’t leave it unattended. This one’s non-negotiable. Heading to another room? Extinguish it first. It takes five seconds and could save your home.
Watch the clock. Most candles have a recommended burn time, usually 2–4 hours per session. Going beyond that risks overheating the container and uneven wax pooling. Give it a rest and relight it later.
Keep it away from draughts. An open window or fan causes the flame to flicker, burn unevenly, and throw off more soot. It also increases the chance of something nearby catching a spark. Close the window, or move the candle.
Don’t burn to the bottom. Stop burning when there’s about 1–2cm of wax left. Burning right to the base can overheat the holder and, in some cases, cause a fire.
Choosing the right candle holder
The right holder matters more than most people realise. Here’s what to look for:
Heat-resistant material. Glass, metal, or ceramic are your friends. Avoid anything plastic. It’ll melt, and quickly.
A stable, wide base. Tall, narrow holders look elegant but tip easily. If you’ve got pets or curious kids about, go for something sturdy and low.
Proper sizing. The holder should fully contain the candle and catch any wax drips. A candle that’s too small for its holder is a wax-spill waiting to happen, and wax on a carpet is a nightmare to shift.
Candles around children and pets
Children and pets are wonderfully curious. Around an open flame, that curiosity needs managing.
Keep candles out of reach. High shelves, enclosed holders, or rooms the kids and animals don’t have access to. If a candle can be knocked over or grabbed, assume it will be.
Don’t leave them unsupervised in a room with a lit candle. Even briefly. Kids especially don’t always understand what “hot” means until it’s too late.
Consider LED candles. They’ve come a long way. Modern LED candles look surprisingly realistic and create a similar atmosphere without any of the risk. If you’ve got a particularly lively household, they’re worth considering for everyday use.
Storing candles properly
Safe candle use doesn’t stop when the flame goes out. If you’ve got a collection (no judgement, candles are great), here’s how to store them properly:
Cool and dry. Heat warps candles and can cause fragrance oils to sweat out of the wax. A drawer or cupboard away from radiators works well.
Out of direct sunlight. UV light fades the colour and degrades the wax over time. A pretty candle left on a sunny windowsill won’t stay pretty for long.
Store upright. Particularly important for pillar and taper candles. Storing them on their side causes warping, which means uneven burning later.
Extinguishing candles safely
Blowing out a candle feels instinctive, but it’s not actually the best method. Here’s how to do it properly:
Use a candle snuffer. It puts the flame out cleanly, without scattering hot wax or leaving the wick smouldering. They’re cheap, and once you’ve got one you’ll wonder how you managed without it.
If you do blow it out, be gentle. A sharp puff can send molten wax flying and leave the wick glowing red, which means it’s still technically alight. Blow softly, then check.
Don’t leave the room immediately. Give it a minute. Make sure the wick has stopped glowing and the wax around it has started to set before you walk away.
Never use water. Pouring water on a candle can cause hot wax to splatter and, if the container is very hot, may crack glass. Just use the snuffer.
Before we go…
Safe candle habits are mostly just common sense, but they’re easy to let slip. Trim the wick, use the right holder, don’t leave the room with a candle burning, and always extinguish properly. That’s most of it, honestly.
Do that, and cosy candlelit evenings are all yours, worry-free. No matter how careful you are though, accidents happen. Find out how Lemonade can help when they do.
Stay safe. Stay cosy.
