How to Choose the Right Candle Wick Size

The wick is the engine of your candle — and getting the size right is the single biggest factor in a clean, even burn. Too small and it tunnels; too big and it smokes. Here’s how to choose correctly.

Why Wick Size Matters

The wick controls how much wax melts and how the flame behaves. The goal is a “full melt pool” — wax that melts evenly across the whole surface — without excessive flame, soot, or mushrooming.

Signs Your Wick Is the Wrong Size

• Tunnelling (wax left on the sides) — the wick is too small.
• Large flame, soot, or smoking — the wick is too big.
• Drowning flame — the wick is too small for the wax depth.

What Determines Wick Size

1. Container diameter — the most important factor. Larger diameter needs a larger wick (or multiple wicks).
2. Wax type — soy, paraffin, and coconut burn differently and need different wicks.
3. Fragrance and dye load — heavy fragrance or colour can require a slightly larger wick.

Cotton vs Wooden Wicks

• Cotton wicks — versatile, reliable, and easy for beginners.
• Wooden wicks — give a gentle crackle and a wide, even burn.

The Golden Rule: Test Burn

Always test-burn a new candle recipe. If it tunnels, size up; if it smokes, size down. A simple wick sizing chart plus a test burn will get you a perfect candle.
