I usually cut my bindings at 2", and sew using a 1/4" seam allowance, so when I'm doing two colored bindings I cut the two strips at 7/8" and 1-3/4",
When the strips are sewn together, you get a binding strip width of 2".
The smaller side would be for the front binding - if you do it the traditional way where you attach the binding to the front and turn to the back for handstitching.
If you want it a bit wider, add the same amount to both strips - like 1" and 1-7/8", and adjust the seam allowance you use to sew the binding to the quilt top to 3/8".
Always helps to cut some scraps to test first.
