Hi there, Basic Hearth Dimensions. To keep fire, ashes and embers a safe distance from the floor in front of a fireplace that has an opening 6 square feet or smaller, the hearth should extend at least 16 inches in front of the fireplace opening. The hearth also needs to extend 8 inches to each side of the opening.
What is it that you want to know about a fireplace hearth? Please elaborate so we can assist you.
We are building a new home, what’s the standard height from the floor, width across the front, and depth or seating area of a fireplace hearth?

Contact your County as they will have building codes that you will have to follow to get an approval.
