We have conducted thorough research and found the necessary information. To check it out, please continue reading.

What are the typical fireplace dimensions?

In general, fireplaces measure 36″ by 30″. It is possible to find fireplaces in just about any size larger than 24″x24″ up to 48″x32″ and higher. Fireplace inserts are usually measured by their width in inches and range in size from 20 inches to 60 inches.

Standard fireplace width:

Almost all fireplaces are around 42 inches wide. A couple of small fireplaces can have a width of 36 inches. The mantle should be about 12 inches directly above the opening for height.

Fireplace depth:

The depth of the fireplace is generally measured from behind the firebox to its front. Studies have shown that a fireplace would function seamlessly if it is 16 inches deep. Anything less or more can cause problems.

Standard fireplace opening dimensions:

According to the latest studies, a standard fireplace opening is at least 24 inches high, 24 inches wide, and 16 inches deep. The height can go up to 29 inches, while the width can go up to 36 inches.

Standard fireplace surround dimensions:

Now it is time to learn about the dimensions of the elements surrounding the fireplace. The distance between the fireplace and the hearth must be 37 inches. The rear end of the firebox must be between 14 to 19 inches. Its height must be 14 inches.

What are the dimensions of these fireplaces?

The aforementioned section has hopefully made you aware of average fireplace dimensions. But what if you decide to build a particular type of fireplaces, such as an electric fireplace or a gas fireplace? You can rely on the standard measurements then.

Masonry fireplace dimensions:

Masonry fireplaces are constructed on the site from brick or stone and mortar. They are an integral part of your property’s structural design. In other words, you must build a masonry fireplace right when you are building your house.

The height, depth, and width of masonry fireplaces are as follows –

  1. Height is 16 to 18 inches
  2. Width is 24 to 28 inches
  3. Depth is 8 to 10 inches.

There may be subtle variations based on the geographical location of a house. Wind patterns also have a role to play. Go through the building codes for a more accurate measurement.

Gas fireplace dimensions:

Gas fireplaces have impressed larger segments of the population because they are safe, convenient to use, easy to install, and affordable. Generally, gas fireplaces are divided into three sizes – small, medium, and big. But what are the gas fireplace dimensions standard?

The small ones have a height, width, and depth of 26, 17, and 14 inches, respectively. The medium ones have dimensions of 29, 20, and 14 inches, and the large ones have 32, 34, and 16 inches.

Electric fireplace dimensions:

Electric fireplaces can heat a room more efficiently and quickly than a standard wooden fireplace. They reduce energy costs and are considered safe. The height, width, and depth are 18, 23, and 11 inches. The measurements vary according to the models.

Fireplace insert dimensions:

Most fireplaces, whether wood burning or gas, have openings 36 to 42 inches wide.

Corner fireplace dimensions:

Corner fireplaces have different dimensions. For the best viewing experience, the distance between the corner and the mantel must be about two feet. Though, in some cases, three feet is believed to be ideal.

Double-sided fireplace dimensions:

Double-sided fireplaces have a height of at least 52 inches. The width and depth are 44 and 25 inches. Such fireplaces have more depth because they tend to extend from one room of your house to another.

  • Fireplace mantel dimensions:

Most fireplace mantels sold are between 66 to 78 inches. However, you can customize the mantel as per your requirements. A mantel that has a face height of six inches is ideal for a large house but seems overwhelming in a small space.

What affects the size of a fireplace?

There are a couple of factors that you should consider when building a fireplace. These factors affect the size of the fireplace.

Room Size:

The fireplace’s size must correlate with the room’s size. You can overheat the room if a huge fireplace is installed in a small room. The opposite is true too. If you have a small fireplace in a huge room, the room would not be adequately heated. The fireplace would not complete its purpose or warm the room.

Type of Fireplace:

The type of fireplace has a bearing on the structure’s size. The age-old brick-and-mortar fireplace is larger than the contemporary ones. If you wish to build a brick-and-mortar fireplace, be prepared for a huge structure. The prefabricated fireplaces, however, can fit into any space. They can be custom-built as per the style and size you have in mind.

Heat Output:

You must consider the heat output of fireplaces too. Gas fireplaces generate about 8000 to 60,000 BTUs, while wooden fireplaces give out 20,000 to 40,000 BTUs. If you want your house to warm up efficiently within a short period, you must opt for the former without any hesitation.

The Climate:

Do you live in a cold place where it is snowing frequently? If yes, you may need a big fireplace that can keep your house warm for a long. However, if you live in an area with a moderate climate and want to get a fireplace for a show, smaller models will do.

What are the measurable parts of a fireplace?

How can you measure the size of a fireplace?

You will need a tape measure to find out the fireplace dimensions.

Measure front:

Measure the front of the fireplace that is the mantel and its shelf.

Measure back:

Measure the back side too. Please go through the process twice to be accurate.

Measure center depth:

To determine the center depth, measure the distance between the fireplace cavity and the back wall. This is the standard fireplace depth.

Take front height:

To measure the height of the fireplace, you have to find out the height of the opening. Take measurements on the left, right, and center.

Measure the distance between the top and other parts:

Now measure the distance between the top of the fireplace and its other parts. In this way, you will get a fireplace of the right size.
