Wick Size for a 3.5" Candle Container
3.5 inches sits right at the edge of single-wick territory. Round containers at this width can still work with one wick if you pick the right size - our tables above show the largest single-wick sizes in each family - but this is also the diameter where a lot of makers start testing a two-wick layout instead, especially for wider, shallower vessels rather than tall jars.
The decision usually comes down to shape and depth rather than diameter alone: a tall, narrow 3.5 inch jar often burns fine with one large wick, while a wide, shallow 3.5 inch bowl-style container is a better candidate for two smaller wicks spaced apart. If you go the multi-wick route, drop down to the recommended single-wick size for a narrower diameter and use two of those rather than trying to double the size of one wick.

Frequently Asked Questions
Should a 3.5 inch candle have one wick or two?
It depends on the container shape more than the diameter alone. A tall, narrow 3.5 inch jar usually works with the single-wick sizes shown above; a wide, shallow container of the same diameter often performs better with two smaller wicks. Burn-test both configurations if you are unsure.
What is the largest single wick size for a 3.5 inch container?
See the tables above for the top of each wick family's recommended range at 3.5 inches in soy wax - the same figures shift according to the wax adjustment table on the main wick size chart page if you are using a different wax.
Does a 3.5 inch candle need a different burn-in time?
Yes, generally longer than smaller containers - allow up to 3-4 hours on the first burn so the melt pool has time to reach the edges before you extinguish it. Cutting the first burn short is one of the most common causes of tunneling at this size.
