Lets say 4 for a sitting area and such.
Standard fire pit size.
I like to plan for about 5 feet around the fire pit for seating and access.
Built in units often have an exterior dimension of 36 inches to 58 inches.
The optimal size for a fire pit is between 36 and 44 inches inside diameter.
If you re choosing low slung seating such as adirondack chairs don t forget to account for the extra real estate they take up.
Be sure that you leave room to move chairs around and walk behind them.
Local ordinances permitting your fire pit should ideally measure between 36 and 44 inches wide including.
You also need to take the depth in ground or height above ground of the fire pit into consideration.
When marking out the area where you want to build your fire pit allow for the outside diameter of the circle.
15 to 20 feet 4 6 to 6 1 meters long and wide or larger most fire pits besides the small movable models are 3 to 6 feet 0 9 meter to 1 8 meters across.
Or you go up to 6 feet wide including the thickness of the walls to accommodate six or more people.
A fire pit itself is rarely bigger than four or five feet across and the patio space around it should be an additional six feet or so on all sides.
A good rule of thumb is to make an above ground fire pit 12 14 inches tall.
By having a wider coping you can use the fire pit for more the just a fire pit.
Size of your fire pit generally a good inside diameter for a fire pit is 36 to 44 inches.
If you want to be able to sit on the edge of the pit itself go a bit higher 18 20 inches will be comfortable.
Cut the circle out of the soil or sod using a shovel and dig down to a depth of about 6 inches.
Most store bought units are available in a 24 inches to 30 inch size.
As an added precaution the fire pit should be lined with a thick steel ring like the ones used for park campfires.
Building a fire pit yourself offers room for customization on every detail size included.
The size of fire pits varies greatly.
This is a few inches shorter than standard patio furniture seat height.
So at the 36 inside diameter with say 14 coping that gives us an outside diameter of 36 14x2 64 inches.
