I use 2.5 inches, but also like to leave that 1/4" of batting and backing beyond the quilt top. It gives the binding some substance, which I really prefer.
Have you tried the faux piping method? It uses 2 strips 1.5" of the piping and 1.25" of binding material. Sew them together, press seams open, then press in half. Sew on the back of the quilt, then turn to the front. It makes a wonderful piped accent. The best part is that you machine stitch in the ditch and no hand sewing.
Here is one tutorial. She gives reasons for pressing to one side or the other.

I use this technique on any quilt with minkie backing, which I don't like hand sewing, and one others that I'm either happy to be done with, or can't imagine sitting for 3 weeks hand stitching at night. (Recently a 116"x116" king sized quilt for my parents.)

I use 2-1/2" and sew binding on with a 3/8" seam. Works well for me.

I use 2.25 and cut my batting and backing a quarter inch bigger than the quilt to give it some filling.

It depends on the weight of my batting. I normally use 2 1/4 but have used 2 1/2 with a thicker poly batting. I normally use 2 on wall hangings.

2 1/4 is my size.

When I started quilting I was afraid of the binding and struggled with corners, just like everyone else. I started out with 4" bias strips, folded in half and ... well you know the process. That was OK for a few quilts then I began making my binding more and more narrow as I became more skilled. I now use 2.5 inches and sometime just a smidge larger depending on the look of the quilt and amount of fabric I have left to make the binding.

To all of the new quilters, the more narrow binding is actually easier to use but I sure learned a lot while trying the wider binding too. Be gracious with yourself and do what feels right for YOU.

2 1/2 or 2 1/4 double fold bias.

2 1/4" for me. Anything smaller and I'm constantly tugging on it. Larger doesn't look right to me.

Your quilt, your rules (unless you are entering a show) Also, size of the original quilt may make the determination of binding size. Small wall hanging, one fold skinny binding (no wear on the binding, do you NEED it to be folded?)?

I use 2 1/2" double fold binding sewn to the back, then flipped to the front and machine stitched with a bobbin thread that matches the backing. I use a "stitch in the ditch foot" or a "blind hem foot" with my needle set to the right of center. My stitching on the back usually lands just to the outside of the binding, on the backing, so almost invisible. All my quilts are made to use, wash and love, so I want the bindings secure for years of use.
