How Do I Correctly Measure My Fireplace for a Fireplace Mantel?


Measuring

In most instances, its very easy to determine the correct size mantel for your fireplace as fireplaces generally come in two sizes.

  • If you have a 36" fireplace - the inside width of your mantel should be 48".
  • If you have a 42" fireplace - the inside width of your mantel should be 54".

This diagram below shows a few other things to consider when measuring your fireplace for a mantel.

 

Outside Width (Leg to Leg) - This measurement is generally the same as shelf length, but can be different. You want to make sure, if it measures differently that the mantel will still work for your application.

 

Inside Width - This is an important measurement, as you need this to be accurate to work in conjunction with your fireplace facing - more on this in the diagram below.

 

Height of Mantel - The height needs to clear your firebox opening, this will also determine if you will need to use corbels. Think of corbels as little blocks that go on the bottom of the legs if the mantel needs to be higher.

 

Inside Height - This needs to clear the header. The header is the facing (marble, tile, slate) that is above the firebox - it is generally 8" high, but can vary.

 

Distance to Nearest Impediment - You want to make sure your mantel will not interfere with an adjacent window or light switch.


 

Other Things to Consider when Measuring- Shelf Depth, Returns and Return Depth

Shelf Depth - The depth of the shelf is generally eight inches, but this can vary - make sure you choose the width you need.

 

Return and Return Depth - The return depth is simply a term for how far the foot of the mantel projects. More importantly is what is called the return. When a mantel is made, there is a recessed area in the back called the return - it allows for the thickness of materials to go behind it. The standard size of a return is 1 1/2" - this almost always works with slate, tile, and granite. If you have brick, you will need to get a mantel with a larger return - the mantels below are all available with an option for a custom return:

 


Working with Your Fireplace Facing

 

Mantel Facing

 

When Ordering a mantel you will want to make sure it works correctly with your facing. 'Facing' is another name for the material surrounding your fireplace opening.

This is usually tile, slate or marble. Facing is generally six inches (left to right) on each side and eight inches on the top. This area is also called the header.

If you have measurements other then these, a custom mantel may be the answer for you - but don't worry! We offer custom mantels at lower prices than other companies charge for their stock mantels:
