Hey peeps, I am going to install a 15’ in diameter circle made of pavers here where I have a bald spot on the lawn. I have had a hard time getting good numbers on 3/4 minus to put in after I dig out the space; should I order enough for 3”-4” for before it is compacted down?

Also… should I go ahead and begin the hole exactly 15’ in diameter, and angle it out toward 16’ at the top so I have room to put in the pavers and reinstall grass around the project once it is complete?

I'm looking to put down a paved area for a fire pit in the back yard, and a moderate circular size would be nice,preferably in something like recycled brick. Taking a quick look around, it doesn't look like many places do curved paving at all, let alone in different diameters, for making nice circular areas.

Any tips for how I can do this fairly easily?

I can source a brick saw pretty easily, but I don't want to have to cut a million bricks myself if it can be avoided. I could just lay the pavers square, and cut the outside ones to a circle, but I don't love that design. Other ideas? Am I just looking in the wrong place for suitable pavers?
