Question 1

What size wick for a tealight candle?

Accepted Answer

Standard tealights are 1.5 in (38 mm) inside diameter. In soy, use CD-4, ECO-4, HTP-31 or LX-10. In paraffin, drop one size to CD-3 or Zinc 34-24-18. Beeswax runs hotter, so wick up to CD-6 or square-braid 3/0.

Question 2

What size wick for a votive candle?

Accepted Answer

Votives are typically 1.75 in (44 mm) inside diameter. Soy takes CD-6, ECO-6, HTP-52 or LX-12. Paraffin votives run one size down. Beeswax votives need square-braid 2/0 or CD-8.

Question 3

What size wick for a 4.5 inch pillar candle?

Accepted Answer

A 4.5 in (114 mm) pillar is right at the top of single-wick range. In soy, try CD-22 or LX-30 single, but two smaller wicks (2× CD-14 or 2× ECO-10) almost always burn cleaner. In beeswax, go straight to 2× CD-14 or 2× TCR 24/14 with 30 to 35 mm centre-to-centre spacing.

Question 4

What size wick for a 5 inch or 6 inch pillar?

Accepted Answer

Above 4.5 in, single-wicking is not recommended. A 5 in (127 mm) pillar wants 2× CD-14 or 2× ECO-10 in soy. A 6 in (152 mm) three-wick pillar wants 3× CD-12 or 3× ECO-10. The multi-wick calculator above returns exact centre-to-centre spacing based on melt-pool geometry.

Question 5

What size wick do I need for my candle?

Accepted Answer

Measure the vessel's inner diameter, pick a wick series rated for that diameter in your wax type, and always test-burn a plain wax candle first. A correctly sized wick reaches a full melt pool to the jar wall in 2 to 3 hours without mushrooming or sooting.

Question 6

What size wick for an 8 oz candle?

Accepted Answer

Most 8 oz jars are around 7 cm (2.75 in) inside diameter. In soy, start with CD-10 or CD-12, ECO-10, or HTP-83. Wick up one size if your fragrance load is above 9 percent or your jar is closer to 8 cm.

Question 7

What size wick for a 10 oz candle?

Accepted Answer

A 10 oz jar is typically 7.5 to 8 cm inside diameter. Start with CD-14 or CD-16, ECO-14, or HTP-104 in soy. If the jar is over 8 cm, two smaller wicks (2 x CD-8) often burn cleaner than one big one.

Question 8

What size wick for a 12 oz candle?

Accepted Answer

12 oz jars are usually 8 to 9 cm inside diameter. Try CD-18 or CD-20 single-wick, or step up to 2 x CD-10 for a wider, faster melt pool. Above 9 cm, multi-wicking is almost always cleaner.

Question 9

What size wick for a 4 oz candle?

Accepted Answer

4 oz jars are typically 5 cm inside diameter. Use CD-4 or CD-6, ECO-4, or HTP-31 in soy. A small wooden wick (0.5 in flat) also works if you want a crackle.

Question 10

What size wick for a 3 inch candle?

Accepted Answer

A 3 inch (7.6 cm) candle wants a wick rated for around 7.5 to 8 cm. In soy that's CD-14, ECO-14 or HTP-104. In paraffin, drop one size because paraffin throws more easily than soy.

Question 11

What size wick for a beeswax candle?

Accepted Answer

Beeswax burns hot and slow, so wick larger than soy. Use square-braid 1/0 or 2/0 for a 5 to 6 cm pillar, 3/0 for a 7 to 8 cm pillar, and 4/0 to 5/0 for a 9 to 10 cm pillar. Hemp 30-ply and TCR 24/14+ also work in container beeswax.

Question 12

What size wick for mason jar candles?

Accepted Answer

Half-pint mason (regular mouth, about 6 cm inside) takes CD-8 or CD-10 in soy. Pint regular-mouth (about 6.5 cm) takes CD-10 or CD-12. Wide-mouth pint (about 8.5 cm) usually needs 2 x CD-8 or a single CD-18.

Question 13

What are the best wicks for soy candles?

Accepted Answer

CD, ECO and HTP all perform well in soy. CD is the most forgiving with high fragrance loads. ECO runs cooler and is the safest first pick for new makers. HTP self-trims and is popular in coconut-soy blends. Always test three sizes per vessel before committing.

Question 14

What if my flame is too tall, sooting or tunneling?

Accepted Answer

Too tall (over half an inch), mushrooming or sooting means the wick is oversized. Drop one size. Tunneling on a full first burn means the wick isn't pulling enough fuel to reach the wall. Go up one size. Always retest after any wax or fragrance change above 0.5 percent.
