A fireplace hearth is a necessity for all solid fuel burning fireplaces, including wood burning fireplaces and stoves. A hearth is not required for electric fireplaces but can be used to enhance the aesthetics of owning an electric fireplace that looks like other types of fireplaces, such as wood burning stoves.

A hearth is normally a brick, stone, marble, or cement slab that sits in front of your fireplace. Made from a non-combustible material, the hearth protects your home’s floor from radiant heat, flying embers, sparks, and burning logs that may roll out of the fireplace.

The hearth is located at the base of the fireplace. It forms the base of the firebox and extends out into the room, both length ways and width ways. It’s what the fire is built on or on which a fireplace grate is placed, and helps protect the floor of your home from the heat of a fire.

For a quick reference, a 36-inch fireplace will probably have a mantel width of 48 inches. A 42-inch fireplace will probably have a mantel width of 54 inches. The mantel should not be so wide that it reaches anything else, like a wall, window or door.

Your mantel should be wider than your fireplace. Typically, a mantel should be a minimum of 3 inches past the firebox on each side. However, more can be better. The average mantel is approximately 6 inches wider than the fireplace on either side, and some can be even wider.

Your fireplace is too small! TV’s are taller than the most popular linear fireplaces, so they already give the impression of being top-heavy on the wall. If your TV is being mounted directly above the fireplace, make sure your fireplace is a little wider than your TV.
