How to Choose Candle Wicks for Candle Making: Candle Wick Size Charts

I’ll even go so far as to say that the containers, type of wax, and scent you select won’t matter if you use the wrong candle wicks. Looking at the side of the candles shows the difference in melt pool depth between the properly wicked candle in the center and the over wicked candle on the right. It is also apparent how much faster the candle on the right is consuming the wax. An over wicked candle will not burn as long as one wicked correctly. When double-wicking a candle, you will use two wicks instead of one. Instead of basing the wick size on the total diameter of the container, you need to divide the diameter in half.

If the wick is too small, the candle will struggle to stay lit. If the wick is too large, the candle will burn too quickly and produce smoke. The ideal size wick will make a uniform flame without any issues such as tunneling or smoke. After burning for four hours the surface wax should be molten from rim to rim of the container. If the pool of molten wax is significantly deeper than 1/2 of an inch, the wick may be too large. A mushrooming candle wick is a sign that the wick you are using is too big or the wick simply needs to be trimmed.

About our wick guide

Hi, I’m Carl Adamson, one of the founders here at Candleers. A few years ago I got really into the art and craft of candle making, initially with soy wax container candles. My friends started asking me to make candles for them and pretty soon it turned into a nice side-business. I started this website as a way to document what I’ve learned over the past few years and hopefully help others in the process. Use the 3 wick sizes to test your candles and if one of them is not perfect then consider testing out two smaller wicks per candle to help resolve the situation. I recently made some 4 oz soy wax candles in tin containers using CD 6 wicks.

  • These wicks offer you very good rigidity during the production of container candles.
  • The width of the tunnel created by the burn pool is usually determined with the initial burning of the candle.
  • You’ll then need two wicks that can melt each part of the candle.
  • The candle on the left is under wicked meaning the wick size is too small for the candle.
  • We offer a large variety of diameters (sizes) and lengths available in several different series.

The ECO series is a flat, coreless cotton wick braided with thin paper filaments interwoven for burn stability. This braiding technique also greatly improves rigidity candle wick size chart compared to standard cotton and paper cored wicks. They have been designed to significantly reduce the “afterglow” and smoke often seen in paper cored wicks.

Candle Wicks: Getting Started

The nomenclature of square braid cotton wicking refers to the number of bundles, the ply of the wick, and how tightly it is braided. The 6/0 to 1/0 range of wicks, are constructed a bit differently than the larger wicks, but all of them are square which helps to channel the wax fumes up to the flame. It is important to keep your wicks well labeled and separated since similar sizes look identical. Often the only difference is the tightness of the braiding.

Referring to the characteristics of a right-wicked candle mentioned at the beginning, you can find out which candle wick size works best for this recipe of candles. This wick should be the right wick for your candles. You can try LX12-28 depending on the height of your pillar candles.

Wick Sizes

Square braid is the best wick for beeswax and was designed for this purpose. They can also be used in other waxes like paraffin and soy. I’ve been a candle maker for years and love discussing every step of creating candles. But, I’ve noticed, for whatever reason, that candle wicks are often the last choice or even an afterthought when it comes to candle making. Now that you know what to look for, adjusting the wick size of your over or under wicked candle is easy.

Create a mixture of enough material to make three identical candles, the only difference in these candles will be the size of the wicks in them. These three different wick sizes will allow you to test a variety of wicks allowing you to see the impact of your wax, fragrance oil and dye combination. This chart will tell you which wicks you need for paraffin wax container candles based on the wax type and the diameter of the container that you are using.

The blocks above, show the top and bottom of a wax block that I bought. From the top, it looks reasonably clean, but on the bottom, quite a bit of honey can be seen. This block will take some time and work before it can be used.

Confused about how to make candles using wooden wicks? Looking at the chart, you can go with two LX 12 or ECO 4 wicks. Or, you can choose two of the smallest wooden wicks.

Use two candle wicks when candle size is nearing 4 inches in diameter. At a certain point, increasing candlewick size produces too large and too smokey of a candle flame. Prevent those things from happening by using two smaller wicks instead. For example, use two CD 6 wicks instead of a CD 24. So, we think we should choose the right wick sizes, instead of the best candle wicks.

You can try to use a smaller wick, trim the wick you are using or change the wick type altogether. Zinc wicks are known for mushrooming so if that is what you are using, consider another type. Light the candle and let the wax melt from rim to rim before blowing out the flame.

If you are testing more than one wick, make sure the candles are clearly labeled. As you can see, the actual diameter is about the same, bu the number of threads and the configuration of the thread clusters that make up the wicks are different. We are a group of friends that LOVE all things candles! Record the way the candle looks when you light it, how it works after 2 hours and how it looks after 4 hours. Once the candle completely cools, repeat steps seven and eight.

This wick gives a slight curl when burning which reduces carbon buildup and makes the wicks self-trimming. This wick is ideal for hand dipping and extruding and dipping machines. This wick is constructedof 100% natural fibers with a chemical treatment to improve the burn performance. Spending time choosing wax type, color, and scent, to then watch your beautiful candle burn too fast—or not at all—can be frustrating.

Consequently, the container will be too hot or even shatter if you’re using a glass container. But if not, you need to choose the right wick size by yourself. The only way to know how long and how thick your candle wick needs to be is through testing. It’s not easy, but we will walk you through the whole process.
