**Length:**

**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.
