calculating fabric yardage- did i add this correctly?

kzsnyder

So I need to make 12 table runners. They should be 20 inches wide, and 10 feet long. The fabric comes in 60 inch width.   Im thinking I need 15 yards of fabric... right....?
20 inches is 3=.55 yds... 120 inches is 3.33 yds... times 12 tables... HELp..;-p

You want to make sure to add in seam allowance. That would be 1/2" (approx) on each edge, so 1" all the way around. If you want to fudge it a bit you could go with your original measurements (60" wide = 3 runners) and they would just end up being 19" wide at the end.

As for the length, let's see. 10 feet x 4 (with 3 runners per length because of the 60" width) = 40 feet/3 = 13.33 yards.

I would get 14-15 yards just as a precaution but if you want to save a few bucks go for 13.5 yards and cut accurately.


Remember, measure twice, cut once! Good Luck!

You need 13 1/3 yards. Each width will yield 3 runners (60" divided by 20"). The Length of the runners is 3 1/3 yards. Multiply 3 1/3 by 4 to get 13 1/3.

Who says you don't need to use fractions in the "real" world.

Ditto Bubbalub.  That's correct.

15 yards is pleanty as long as you don't mind them being about 19" wide instead of 20, as Bubbalub said, you need a seam allowance.
