The braid of the wick has a direct impact on the flame. Wicks are twisted and braided together. They are made from individual threads, dipped in wax, and assembled, which is why they burn so easily. However, it’s important to choose the right wick for how you want your candle to burn. Thick wicks are often braided using many threads, and the resulting flame is large, but tends to burn quickly. Thinner wicks can be made with as few as 3 threads, but they tend to burn much more slowly than the larger counterparts.
As a general rule, if you are going to choose the wick for a standard candle, opt for the thinner wicks that have been braided tightly. These wicks are going to provide you with that even burn you are looking for, but also give you a lasting candle that you can enjoy.
Also, check to ensure that the wicks you choose are braided rather than merely twisted, as the braided wicks also tend to burn at a slower rate than the twisted varieties.
