How to Measure for Gas Logs

Though there is no exact formula for measuring gas logs, we believe the techniques listed below will help you determine the size logs that will best serve your needs.

Most gas logs require a fireplace that is at least 14" deep. For the width of the logs, simply measure the width of the fireplace right in the middle and subtract 6" from this measurement. Purchase the logs that come closest to your measurement. (See below)

Measure the middle width of the fireplace minus 6 inches
Buy the logs that are closest to that measurement.

OR, if you have real logs and a grate handy, you might try stacking the logs on the grate to make sure they fit inside your opening and then measure the actual logs. If you don't have real logs at your disposal you might also try using cardboard or newspaper as an alternative (see below).


In both of the examples shown above, the fireplaces are the same width and height at the opening. However, notice that Example "B" tapers back much quicker than the other. Therefore, Example "B" would use a smaller gas log set than Example "A".

We hope this is helpful to you as you shop for your new gas logs. Please don't hesitate to ask the sales staff in any of our showrooms for additional assistance.
