Joining binding strips
I can't believe I'm asking a math question, but here goes. When determining how many binding strips to cut, how do you calculate how much will be needed for the diagonal joins? I needed 320" of binding, which is about 8 strips. I cut nine to allow for the 8 joins. I only used about 6" of the ninth strip. My mind says that a diagonal join should use more. Do you only need about 1/2"? It's not important, but I don't like being confused.

For a diagonal join you will lose a little more than the width of your binding strip.
Your diagonal stitch line goes from corner to corner of an imaginary 'square' IYSWIM, and when you open it out you have 'lost' the length of the overlap. The extra length of binding that you add to your calculation is one 'overlap'. Overlapping the final ends of binding and cutting it longer by the measurement of the width (eg an extra 2 1/2") is how I make the final join of the binding when attaching it to the quilt. Easier to do than explain. You will also lose a little binding with the mitres on the corners.
Left over binding always come in useful for scrappy binding on Linus quilts or for scrappy patterns.

To be clear, I meant that you add one overlap per join.

When I measure for my binding I take all 4 sides plus add 10". Divide it by 40 instead of 42, figure that would cover the diagonal seams I use. I've never had not enough. The leftover gets put into my 2.25" basket of scraps.

I have difficulty figuring out the amout too - some times straightforward and sometimes not 
I have used this site for their "quilt binding calculator" with success and have always added a little but more "just in case".
