How deep should a fireplace mantel shelf be?
A depth of 7 inches is ideal for most mantels, as it allows plenty of room to accommodate decorative objects. Keep in mind that the top and the sides of the mantel should be the same depth. First, use a measuring tape and pencil to measure and mark the mantel top to size.
