Need help
 

figuring out how much I need for my backing on a 74x82 1/2 inch quilt. Thank you far all your help in advance. Its been a while and I have forgotten how to figure it out.

Here's a online quilting calculator to help you out! http://www.quiltersparadiseesc.com/C...Calculator.php

great tool! thank yoou very much. I am short by one yard. Will have to figure that out.

You only need 2 yards and 1/4 yards if you get backing that is at least 90 inches wide. If you use regular width fabric (44 inches) you need 4 1/2 yards (make sure it is at least 43 inches wide NOT including selvages)

If you're short on backing fabric, look at these links. I suspect that where your quilt is so wide, it may not help you but...for future reference then.

Good luck.

Just add 3-4" to each side, top and bottom of your top and you should have enough.
