The numbers below are for that 85 by 90 inch quilt, with 4 inches of overhang for the backing and batting, 2 1/2 inch binding strips, and ordinary 42 inch quilting cotton. Change the quilt in the card and they follow.
Materials for a 85 × 90 inch quilt
Four inches of overhang on the back and the batting. Binding is 2 1/2 inch strips. The top is not in this list, because a pieced top is not a rectangle.
- Binding, 42" fabric
- 5/8 yard
- Backing, 42" fabric
- 7 3/4 yards
- Backing, 108" fabric
- 2 3/4 yards
- Batting to cut
- 93" × 98"

The top is not a rectangle
A pieced full top is not "85 times 90, divided by the width of the fabric." Seams, sashing, and the way a block is cut all change the yardage, and a single number would be a guess wearing a precise face. Design the top, or follow a pattern that already counted the pieces. Quiltler's fabric calculator does that from the design itself.
People still want a shopping range. A simple full top is often somewhere around 6 to 9 yards in total, split across several fabrics, before backing and binding. Treat that as a budget for the shop, then replace it with the pattern's list or a design before you cut.
Full versus queen
A full quilt finishes at 85 by 90 inches in our guide; a queen is 90 by 95. Five inches in each direction sounds small until you buy backing: the full already wants three panels of 42 inch cloth, and the queen does too — but the queen’s panels are longer. If your double bed is really a queen mattress in the room, measure before you cut. The quilt size calculator turns mattress plus drop into inches.
For the pieced top, treat 6 to 9 yards as a shopping budget across several prints, then replace it with a pattern list or a design. The yardage from design page explains why a single rectangle number lies about patchwork.
