Standard Size Mantels
For fireplaces 30" wide to 42" wide
This selection of mantels is designed to fit more standard fireplaces. Many models are available in 2 sizes - those that fit fireplaces roughly 36" wide or less, and those that fit fireplaces 42" wide. (If your fireplace is smaller than 30" wide, check our selection of of Small Mantels).
Why these 2 standard size mantels? Since the 1970's prefabricated metal fireplaces have grown exponentially in popularity, and whether they be wood or gas, most of these fireplaces have openings that are nominally 36" wide or 42" wide.
HOW TO MEASURE for a mantel
- Note your fireplace width____________ x height ____________
- For wood burning (or any open burning) fireplace you need at least 8" clearance from each side and 10" clearance from the top of the opening for spark & heat protection. (If there's a wood stove insert in your fireplace, check the insert manufacturer's required mantel clearances)
- Fireplace width + 16" ________________ fireplace height + 10" __________________
- The above measurement tells you the MINIMUM INSIDE OPENING required for your mantel
- Measure your hearth (the surface on the floor)
width (length) ______________ x depth ____________
- Ideally you want the legs of the mantel to be able to set completely on the hearth surface. You can get by aesthetically in some situations with the mantel legs on either side; what you don't want is mantel legs that sit only partially on the hearth surface.
