Round fire pit dimensions.
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.
The size of fire pits varies greatly.

Lets say 4 for a sitting area and such.
If you plan to use the edge of the pit as a sitting wall you ll want it to be about 20 inches.
While larger fire pits suited for entertaining groups can be up to 6 feet wide.
So now figure how much room you want to have around the fire pit.
So at the 36 inside diameter with say 14 coping that gives us an outside diameter of 36 14x2 64 inches.
By having a wider coping you can use the fire pit for more the just a fire pit.
Built in units often have an exterior dimension of 36 inches to 58 inches.

Smaller more intimate fire pits are around 3 feet wide.
The fire pit uses charcoal or burning wood as its primary fuel and has a round surface with a wire mesh screen to prevent sparks from flying.
These measurements include the thickness of the walls so realize that the total width of the fire pit is not the same as the width of the burning area.
The exact height you choose for your fire pit will depend on how you plan to use it.
