Arithmetic, not a guess
How much do I need?
Yardage is width, length and allowance. It is arithmetic, so here is the arithmetic — with every assumption written on screen and the working shown, so you can argue with it.

0.00 yd
—
What this does not include. Pattern repeat, nap direction, shrinkage, or matching across seams. On a printed or jacquard cloth with a long repeat, add one repeat per drop. When it matters, call the counter before you buy — that call is free and a wrong cut is not.
Rounding
The counter cuts to the quarter yard, so the figure above is rounded up to the next quarter. The unrounded result is printed under the box so you can see exactly how much you are being asked to round.
