There are multiple factors that we need to take into count that will help us decide what the size of the fireplace would be. Below are some of those variables that we need to understand before getting a fireplace.

Furthermore, make sure to remember that the size of our television is measured on the diagonal but fireplaces are measured straight across.

Room Size:

When getting the right size for the fireplace, the size of the room it is going to be in also needs to be factored in. This is necessary to get the right type and size of the fireplace for your home.

Type of Fireplace:

The type of fireplace can play a major role in how big it can get while deciding to get one.

The fireplace’s design also comes into this category. There are essentially two types of fireplaces, one is solid fuel and the other is gas.

Heat Output:

It is not common for fireplaces to output unnecessarily high heat to make the room neutral or warm.

Sometimes they can just be a showpiece and sometimes they just output the minimum amount of heat. Thus, depending on the heat output the size of the fireplace changes.

The Climate:

In some regions, the climate can be very unpredictable. Then again in some other regions, the climate can be very cold. Therefore, depending on where we live, we need to adjust the size of a fireplace.

What are the measurable parts of a fireplace?

When it comes to measuring the parts of a fireplace there are several things we can measure. The mantelpiece, for example, can be measured, apart from just being there to make the fireplace look good they also serve the purpose of the hood that prevents smoke from entering the room.

Furthermore, there’s the Corbel, which supports weight. Corbel can be found used in many different kinds of architecture. However, other parts of a fireplace are as much as important as this if not more.

The firebox is the most critical component of a fireplace. Henceforth the other pieces that can be measured are Surround, Plinth, and Hearth. Each of these parts is as important as the mantelpiece and each of them serves a purpose.

Measure front:

At first, we have to measure the front width of the usable floor space for our fireplace.

Measure back:

Next, we need to measure the back width of the fireplace. When measuring the width of the fireplace we start by the front opening then go to the backside of it.

Measure center depth:

After that, we need to measure the depth of the center of our fireplace. When we are doing this, we need to make sure that the measurement is in the back center of our fireplace’s cavity.

Take front height:

Finally, we need to measure the front height. We will proceed to take three different measurements of the height from left, center to right. At the end of it, we will take the lowest height among the three.

Measure distance between top and other parts:

It’s crucial to also consider the immediate vicinity of the fireplace. That is why we need to measure the distance from the top and each side of the fireplace to make sure that there will be no combustible materials too close.
