How To Measure Your Existing Fireplace

Fireplace inserts are designed to fit into an existing fireplace. Some inserts will fit in a wide range of fireplace sizes. So, how do you measure your fireplace for a fireplace insert? Let's discuss why it's important to get a fireplace insert that fits!

Typically, fireplace inserts come with a metal surround that acts as a frame, covering the gap between the insert and the fireplace's opening. It should be noted that you do not want a fireplace insert that is too small or too large: If the opening is too small, the insert will not fit, and if it is too large, the surround will not be wide enough to cover the gap between the fireplace insert and the opening of the existing fireplace.
