Bias Binding

Bias Binding
I seldom do Bias binding but I have a quilt that really NEEDS bias so here I go. My question is, How much fabric do I need to cut 240 inches of binding 2 1/2 inches wide? What is the formula? I plan to use a video by Sew very easy to cut and put the binding together. The continues binding looks way to complicated for me.

I may not be thinking properly here - if your fabric is 40" wide (or more) you should need 6 strips = 240", right?
so 6 strips @ 2 1/2" width should be 15". I would go with 7 strips, just in case of error and seam allowances for joining them - (17 1/2", only 1/2 yd.)

here is a continuous bias binding guide and calculator http://so-sew-easy.com/continuous-bi...ng-calculator/

A yard seems like a lot to me, but it depends on how you want to cut the binding piece, whether in a square or rectangle, and whether you're using the continuous binding method (which I gather you are not). For bias you don't really have to cut absolutely on the 45 degree diagonal, since you will have the bit of stretch you want even if you're cutting somewhat off, say at 30 degrees for example. Most of the calulators assume you are cutting at 45 degrees.

Theoretically, it takes the same amount of fabric for a straight cut binding as for a bias cut binding.
Length times width equals area.
However - that does not factor in fabric lost/wasted in joins or matching a design if that is important.
When I can, I cut from selvage to selvage and usually have a couple of big triangles left over. But if a lot of seams don't bother you and you are trying to squeak by with as little fabric as possible, theoretically, 1/2 yard of 40 inch usable width would do it. I would go with an absolute minimum of 5/8 yard (if available) and preferably 3/4 yard.
If it was me - and I had the money and the fabric was available - I would go with 1-1/4 yards.
240 x 2.5 = 600 inches
600 / 40 = 15 inches
That would be the length of 40 inch wide fabric to cover 600 inches of area.
That does not take into account joins, pattern matching, or cutting errors.

I make bias binding all the time and always cut it 2.5 inches wide using piraterogers.com tutorial. Using 28" WOF will make about 440" - 460" inches of binding depending on the width of the fabric. This is the easiest most straight forward method for making bias binding and doesn't waste fabric as you don't start with a square. A yard and a quarter of fabric would make you enough bias binding for one large King sized quilt and a single sized one too!
