The general rule is that the wick diameter should be approximately half the diameter of the lamp's chimney or font opening. The wick acts as a bundle of tiny capillary tubes.

However, pure cotton can be prone to carbon buildup, or "mushrooming," where the tip of the wick chars and expands, disrupting the flame's consistency. The heat of the flame then vaporizes this fuel at the tip, creating a continuous cycle of combustion.
Modern alternatives often feature braided fiberglass or ceramic cores, which provide exceptional stability and rigidity, preventing the wick from collapsing in the reservoir. Font Diameter Recommended Wick Size Best Use Case Small (1" - 2") Thin (1/8") Tealights or small decorative lamps Medium (2" - 4") Medium (3/16" - 1/4") Table lamps and mid-size lanterns.

The diameter and material of the wick directly dictate the speed and volume of this flow, making the match between wick and fuel essential. A wick is not a simple cord; it is a precise capillary system engineered to draw fuel upward at a controlled rate to sustain a clean, steady flame.
