1. What kind of wax are you going to use?
2. What will the diameter of your candle be?

For this you will need to measure the widest part of your jar or mold.

The height of your candle will only matter if your candle is going to be taller than 5.75" tall, because all of our pretabbed wicks are only 6" tall (you require .25" above your candle for lighting). Therefore if your candle will be taller than 5.75", than you will need to purchase spooled wick and tabs to create your own custom wicks.

How much wax your container or mold holds does not impact which wick you will choose.
