Candle Safety Warning Labels Pack of 75 stickers- 45mm (4.5cm)
45mm to cm is simple: 45 millimetres equals 4.5 centimetres, or roughly 1.77 inches. That is the diameter of the round candle safety labels in this pack of 75 stickers, and it is a size that suits the base of most jars, tins and tumblers.
The quick conversion rule is to divide millimetres by 10. So 30mm is 3cm, 45mm is 4.5cm and 60mm is 6cm. Keep that in mind when you measure a flat patch on a container, because a ruler marked in centimetres will give you the answer straight away.
45mm to cm: will it fit on your candle?
A 4.5cm circle needs a flat, smooth area at least 5cm across to sit cleanly. That works well on the underside of a standard 20cl jar (usually 6 to 8cm wide) and on the bottom of a 9cl tin, which often measures around 6cm. On a very small votive cup, under 5cm across, it will overhang the edge and peel.
Measure before you print anything. Check the base, not the widest point of the jar, since many glasses taper inwards and the base is narrower than you think. Allow about 2 to 3mm of clear space around the sticker.
Curved sides are a poor choice. A 45mm round label wraps badly on a jar with a tight curve, and the edges lift within days. The base or the lid is far better.
What candle safety labels should say
Candle safety labels carry the hazard information that UK and EU rules expect on a scented candle. The exact wording depends on your fragrance and the CLP classification of the finished product, so check your supplier's safety data sheet first. A label like this one typically holds the pictograms and short warning lines that fit inside 4.5cm.
Common warnings you will see on a candle label include:
- Never leave a burning candle unattended
- Keep out of reach of children and pets
- Trim the wick to about 5mm before each lighting
- Burn on a heat resistant, level surface
- Stop burning when 1cm of wax remains
Text on a 4.5cm circle gets small quickly. For legibility, aim for a character height of at least 1.2mm on the mandatory elements. If your hazard wording is long, a larger label or a second sticker is the sensible answer.
Candle warning labels and the rules behind them
Candle warning labels are not decoration. If your candle contains fragrance oils classed as hazardous, the CLP regulation requires a signal word, hazard statements, the supplier details and the product identifier on the pack. Many makers add the burn guidance on top of that, which is good practice even when it is not legally required.
Put the CLP elements on the container itself, not only on a box that gets thrown away. A base sticker is the usual place. Keep the contrast high: black on white or clear is easiest to read, and a matte finish avoids glare.
Candle sticker labels: material and application
Candle sticker labels face heat, wax and oil. A vinyl or paper stock with a permanent adhesive copes well when the sticker sits on the base. Avoid placing any label near the flame, and never on the rim.
Apply it on a clean, dry surface. Wipe the glass with isopropyl alcohol and let it dry for a minute. Press from the centre outward, then hold for about 10 seconds. Wait 24 hours before moving the candles into cold storage or packing them.
Other sizes worth knowing
A 45mm circle is not the only option. Makers of wax melts usually need something smaller, because the clamshell packs have little flat space. Wax melt labels in this same 45mm size exist, and wax melt warning labels at 30mm (3cm) suit narrower packs. For shipping boxes, some sellers add a small 25mm stickers set for handling marks, though that is a different job from safety labelling.
Frequently Asked Questions
How many centimetres is 45mm?
45mm is 4.5cm. Divide the millimetre figure by 10 to convert. In inches, it comes to about 1.77.
Is a 4.5cm label big enough for CLP information?
It can hold a pictogram, a signal word and short statements if the wording is tight. Longer hazard text often needs a bigger label. Check the requirements for your specific fragrance before you decide.
Can I stick it on the side of a jar?
You can, but it is not ideal. A round label this size curls on small, curved jars. The flat base gives a cleaner finish and keeps the sticker away from heat.
Do the stickers withstand heat from the candle?
Standard adhesive labels handle the warmth of a base without trouble. They are not made to sit near a flame or on a hot rim. Keep them on the bottom or on the lid.
How many labels does a pack of 75 cover?
One label per candle, so 75 candles. If you use two per product, one for safety and one for batch details, that drops to about 37 candles.
