I would only worry about it being the same on both sides if you are entering a show quilt. Mine is always larger on the back. I cut at 2 1/2 wide so I can use the extra as a 2 1/2 strip. I sew at 1/4 inch so I don't cover design on front and flip to the back. If it's for a show, I cut the batting a little out to even up the binding.
