Is Your Candle Wick Size Right?

I think it’s fair to say what first to comes to mind to a make candle is choosing a candle wax type. This is undoubtedly a necessary step in order to make a candle, but I’ve found the choice of a wick is even more important.

Why does candle wick size matter? Making candles with the wrong wick size will always result in a candle problem. In fact, an incorrect candle wick size can cause a host of candle issues! 

I can tell from experience; that there’s nothing more frustrating than nailing your candle fragrance load and pouring smooth tops, only to end up with a candle that won’t stay lit!

Choosing the right candle wick size for homemade candles can be as confusing for experienced candle makers as beginners. Oftentimes because as candle makers, we make new candles in various containers, shapes, and sizes. 

For example, you will need a different wick size for tea light candles than sugar mold candles or mason jar candles. So, as they say, we’re constantly coming back to the drawing board to choose a candle wick.

If that is where you find yourself today, you’ll be glad to know the five signs your candle wick size is incorrect. And three quick steps to choosing the proper wick using printable candle wick size charts.

How do you know if you are using the wrong candle wick size?

It’s a fact; that candles will not burn the way you expect them to unless you have the right candle wick size. But, how do you know if you are using the wrong candle wick size? Here are five signs your wick isn’t the correct size and how to remedy it!

5 Signs Your Wick Isn’t The Right Size


A flickering flame is a sign your wick isn’t the right size (other than a crackling wood wick designed to flicker).

  • The most common issue is a wick that is too long. Use a wicker trimmer to trim the wick to 1/4 inch and relight the candle. 
  • If this doesn’t fix the issue, that could indicate that the candle wick is too thick and melting more wax than the wick can burn. 


We are familiar with candle tunneling. But do you know the reason it happens and how to fix it?

  • When a candle is lit for a short period of time and doesn’t form a complete melting pool, it will always tunnel. To remedy, burn candles long enough for the wax to melt entirely across the candle’s surface – from edge to edge. 
  • If tunneling persists after trying the above, it’s a fair sign the candle wick is too thin. And that means you need to size up your candle wick to a thicker width, so it has enough strength to create a complete melting pool.

When a candle wick doesn’t stay lit, you’re facing one of two problems: 

  • In many cases, this is a sign the candle has too much fragrance. Use a fragrance load calculator to avoid adding too much.
  • A wick that self extinguishes can also be caused by a candle wick that is too thin or short for the container or candle size. A good reminder is to always measure your candle container or candle mold before choosing a wick. 


Also known as a deep melt pool, a drowning candle wick is a big sign you’ve got the wrong wick size! 

  • A wick that is much too thick for the diameter of a candle will cause a melt pool deeper than half an inch. This will significantly shorten the candle’s life because it’s burning up wax too fast. 


A mushrooming wick earned its namesake for a wick having the appearance of a mushroom when it splits as it burns. It’s a very common issue; in most cases, there’s an easy solution. 

  • You risk mushrooming every time you light a candle without trimming the wick to ¼ inch. You see, when a wick is too long, the wax in the candle often isn’t capable of burning fast enough to keep up with the wick, so the wick splits. 
  • Mushrooming can also appear when a wick has formed buildup from not being trimmed adequately between use. That’s why using a wicker trimmer is number two on my candle care tips. 
  • If the wick mushrooms again after trimming correctly, the wick is possibly slightly too thick.

As you can see now, candle wick size ALWAYS MATTERS!

If you are experiencing any of these signs, read the following three simple steps to choosing the correct candle wick. And see the printable candle wick size charts below to find the correct wick size for the diameter of your candle container.

How Do You Choose the Right Candle Wick Size?

Do the signs above sound all too familiar? Then it’s time to ask, “How do I choose the right wick?” When planning your candle projects, use these three steps to choose the proper candle wick as a checklist. 

1st: Candle Wax Type

Soy, paraffin, coconut, gel, or beeswax; each type of candle wax has a unique melting point and density. And these variances must be taken into account for choosing a candle wick. Reading the recommended wax type for use with a candle wick directly from the manufacturer is a good place to start. They are typically helpful and very accurate, as they have tested extensively. 

2nd: Fragrance Load and Color

The second step is a quick consideration of the amount of fragrance or color you plan to add to the candle. The more color or fragrance you include, the thicker you’ll want your wick to be. Because, remember, too much fragrance can cause a candle not to stay lit! 

3rd: Candle Type and Size

The third step is to take note of the type of candle you will be making. (I cover candle wax recommendations for just about every type of candle here.) Record measurements for the height and diameter of the candle. 

Now use everything you’ve recorded in this checklist with a corresponding candle wick size chart –
