Gas Log Size Calculator

Use our Gas Log Calculator to find the gas log size you need

Most fireplaces are tapered (front width is larger than the rear width). The most critical dimension for sizing is the Middle Width Dimension of the fireplace. This will allow the burner to be centered in the fireplace. 


Example: 42" (front width) + 24" (back width) = 66" / 2 = 33" middle width

When selecting the proper size log set for your fireplace, the Middle Width Dimension must be greater than or equal to the Middle Width Dimension of the sizes listed below:
