However, choosing a fireplace mantel height can be tricky. If the mantel’s height is not perfect, it can change the whole outlook of the fireplace. Moreover, the appearance of a fireplace can affect the outlook of a room.

While selecting the standard height of a fireplace mantel, you should also consider other factors. For example, the height of the fireplace mantel should be according to the size of the room.

**Height of fireplace mantel from floor:**

Generally, the average height of the fireplace mantel can be from 4 feet to 6 feet from the floor. But the normal height of the mantel should be around 5 feet from the floor. Moreover, a gas fireplace mantel height should be at least 4.5 feet.

How tall the fireplace height is also depends on the size of the room. For example, if you install a tall fireplace mantel in a small room, the room will look smaller. Moreover, the space of the room will be congested.

So, you should keep the height of a fireplace mantel short for a small room. You should keep the mantel’s height between 4 and 4.5 feet from the floor.

But if the room is large, you should install a tall fireplace mantel in the room. The height of the mantel can be 5 to 6 feet from the floor for a larger room.

You should also consider the ceiling height from the mantel of a fireplace. If the ceiling height is short, you should also keep the mantel height short. But if the ceiling is high enough, you can install a tall mantel on the fireplace.

**How to select the height of your fireplace mantel?**

While selecting the height of your fireplace mantel, you have to think about some factors. Because the height of the fireplace mantel can be different for different rooms, spaces, and dimensions.

If you don’t consider the factors, the mantel will not look good with the fireplace. Moreover, the wrong height of the fireplace mantel can also make the outlook of the room. So, let’s see how you can select the height of your fireplace mantel.

**According to the room size:**

When choosing the average or standard height of the fireplace mantel, you have to consider the size of the room. Because the appearance of the fireplace can be different according to the room size.

For example, small rooms and large rooms should have different heights of the mantel. If the room is larger, the mantel height should be 6 feet from the floor. But if the room is small, a large mantel will not look good.

So, for a small room, the height of the fireplace mantel should be between 4 to 5 feet from the floor. So, the height of the mantel can change according to the room size.

**According to the ceiling height:**

The height of the ceiling also affects the outlook of the fireplace mantel. When you choose the height of the mantel, you should also consider the ceiling height. The high ceiling should also have a high mantel.

For example, if the ceiling height is short, a high fireplace mantel will not look good. So, you should install a 4 feet high mantel for a short ceiling.

But if the ceiling height is high, you can install a 6 feet high mantel. So, the ceiling height can also vary with the height of the fireplace mantel.

**According to the firebox height:**

When choosing the height of the fireplace mantel, you should also consider the firebox height. Because if the mantel of the fireplace is too close to the firebox, it can be dangerous.

So, try to keep enough gap between the mantel and firebox. If the firebox is 5 feet high from the floor, you should keep at least 12 inches gap.

So, the fireplace mantel can be 6 feet high from the floor. So, the height of the firebox can also vary with the height of the fireplace mantel.

**How high is too high for a fireplace mantel?**

Generally, the height of a fireplace mantel is too high if the height is more than 6 feet. Generally, the standard height of a fireplace mantel is between 4 and 6 feet from the floor. So, **more than 6 feet is too high for a fireplace mantel.**

It also depends on some factors. For example, if a small room has a 6 feet high fireplace mantel, it will look too high for the room.

Moreover, the ceiling height is also important. If you install a 6 feet high fireplace mantel for a short ceiling, the mantel will look too high with the wall.

You should install a 6 feet high fireplace mantel if the room is large. Moreover, a tall mantel will look good with a high ceiling. But if the room and ceiling both are short, more than 5 feet high mantel will look too high.

**What size should a fireplace mantel be?**

Now that you know the standard height of the fireplace mantel, you might also want to know the depth and length of the fireplace mantel. So, let’s see what size a fireplace mantel should be.

**Depth:**

**The standard depth of a fireplace mantel should be between 6 to 7 inches.** Sometimes, the depth can be less than 6 inches if the height of the mantel is short.

But a 6 inches deep mantel will allow you to keep things on top of the mantel. You can also increase the depth of the mantel if the mantel height is high.

**Length:**

Generally, the length of the fireplace mantel depends on the length of the firebox. You should always keep the length of the mantel 12 inches longer than the firebox. For example, if the firebox length is 42 inches, **the fireplace mantel length should be at least 54 inches.**

**How far should a fireplace mantel stick out?**

**A fireplace mantel should stick out at least three inches beyond the fireplace opening.** But if the fireplace has a hood, you can keep a couple of inches excess beyond the hood.

Generally, when you decide how far a fireplace mantel should stick out, you should consider the style and placement of the fireplace. For example, a fireplace can be in the wall or outside the wall. Sometimes, the fireplace has a hood over it.

You should decide how far the mantel will stick out before installing the mantel. Because if the mantel is too far or too close, it will not look good.

**How do you measure a fireplace mantel?**

Now that you know the standard height and dimension of a fireplace mantel, you might want to know how you can measure a fireplace mantel properly. So, let’s see how you can do it.

- First, measure the depth of the fireplace mantel wood.
- To measure the depth, take measurement from the front edge to the wall with a measuring tape.
- Then, you can measure the total height of the wood between the floor and the mantel shelf.
- After that, you can measure the width and depth of the mantel according to the height and length of the wood mantel.

**Final Thoughts**

Standard fireplace mantel height can be 6 feet from the floor if the room is large or medium. But if the room is small, you should keep the height of the mantel below 5 feet. Moreover, the ceiling of the room can also vary the height of the fireplace mantel.
