How much batting for a king size quilt?
King quilts need batting 4″ bigger than the top on every side. The most common king size, 108″ × 108″, needs at least 116″ × 116″: a king package (120″ × 120″).
Every king size
| Quilt | Batting needed | Package | 96″ roll | 120″ roll |
|---|---|---|---|---|
| 100 × 100 | 108 × 108 | King (120 × 120) | too narrow | 3 yd |
| 108 × 108 | 116 × 116 | King (120 × 120) | too narrow | 3 1/4 yd |
| 110 × 110 | 118 × 118 | King (120 × 120) | too narrow | 3 3/8 yd |
| 120 × 120 | 128 × 128 | — | too narrow | too narrow |
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 king size quilt?
Batting should be the quilt top plus 4 inches on every side, like the backing. A 108 x 108 inch king quilt needs batting at least 116 x 116 inches: a king package (120 in × 120 in), or 3 1/4 yd off a 120 inch roll.
Is king size batting big enough for a king quilt?
Not always. Packages are sized for the quilt top, but longarm quilting needs about 4 inches extra on every side, so for 120 x 120 the king package is too small once the overhang is added. 120 x 120 needs batting by the yard.
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 108 x 108 that is 3 1/4 yd off a 120 inch roll.
