What size do you need for your fire pit?

The size really depends on personal taste and preference. Just make sure whatever size you pick, it looks good on your fire pit and will not stifle air flow in your fire pit otherwise this will result in puny flames. Also ensure the size you pick effectively hides the burner.

Alternatively, you could use pea gravel or fire pit lava rocks underneath first then fill up with fire glass.
