How much batting for a full size quilt?
Full quilts need batting 4″ bigger than the top on every side. The most common full size, 84″ × 90″, needs at least 92″ × 98″: a king package (120″ × 120″).
Every full size
| Quilt | Batting needed | Package | 96″ roll | 120″ roll |
|---|---|---|---|---|
| 80 × 90 | 88 × 98 | Queen (90 × 108) | 2 3/4 yd | 2 1/2 yd |
| 84 × 90 | 92 × 98 | King (120 × 120) | 2 3/4 yd | 2 5/8 yd |
| 86 × 100 | 94 × 108 | King (120 × 120) | 3 yd | 2 5/8 yd |
Batting needed = the quilt top plus 4″ on every side, the same allowance as the backing (ask your longarm quilter: some want 3″, some 6″). Package sizes are typical and vary by brand. Roll amounts round up to the next ⅛ yard.

Questions quilters ask
How much batting do I need for a full size quilt?
Batting should be the quilt top plus 4 inches on every side, like the backing. A 84 x 90 inch full quilt needs batting at least 92 x 98 inches: a king package (120 in × 120 in), or 2 3/4 yd off a 96 inch roll.
Is full size batting big enough for a full quilt?
Not always. Packages are sized for the quilt top, but longarm quilting needs about 4 inches extra on every side, so for every common full size the full package is too small once the overhang is added. 80 x 90 needs a queen package; 84 x 90 and 86 x 100 need a king package.
Should I buy batting in a package or by the yard?
Packages are simplest when one fits. Batting by the yard comes on 90 to 120 inch wide rolls: buy the length of the quilt plus the overhang. For 84 x 90 that is 2 3/4 yd off a 96 inch roll (or 2 5/8 yd off a 120 inch roll).
