Keep in mind that you can customize the design to what you want. I have seen guys design these in a number of sizes. The suggestion I always give is to have you build a "mock-up" out of cardboard and put it into your pit to see what it looks like and then you can see it before we build it. These are the general dimensions we work with, but I will build what you want. If there is another size you need, just email me through the link above and we'll take care of ya. God bless you.
