I understand that this is a mater of esthetics and there are different styles of flagstone patio layout - tighter, loser, more uniform, more natural, etc. I'm looking for any rule of thumb range for the size of individual flagstone pieces in a patio. It may be that larger patios can look good with larger pieces. I have been laying them out and I think they are too big. Part of the problem is that there are small pieces filing in gaps and the large pieces make the small ones look very small.
The whole thing is about 125 sq feet and the larger pieces are about 9 sq feet.
