My upholsterer says I need 3.5 yards….how many sq/ft do I need?

Three and one half yards (linear yards 36" X 54" I assume ) is 78 sq/ft of leather. Please remember that only about 85% of the sq/ft is usable due to the hide being asymmetrical and any minor blemishes (15-20% is standard in the industry). As such, you will need to determine whether your upholsterer has factored that in so 78sq/ft will suffice OR, whether you need to factor in the waste (.15) when you buy....so you will need 78 sq/ft x 1.15 = 89.7 sq/ft (approx) for your project.

Thanks!
