Quilt dimensions vary with the pattern and the amount of drop desired at the sides of the bed. JOANN’s quilting field guide lists these common finished-project sizes:
| Quilt type | Finished size (inches) |
|---|---|
| Wall quilt | 29 × 29 |
| Crib | 45 × 60 |
| Throw | 50 × 65 |
| Lap | 60 × 72 |
| Twin | 72 × 90 |
| Double / Full | 81 × 96 |
| Queen | 90 × 108 |
| King | 108 × 108 |
| California King | 120 × 120 |
These are useful planning dimensions, not mandatory standards. The source notes that needs may vary by project. See the JOANN Quilting Field Guide.
Start with the finished dimensions in the chart, then decide how far you want the quilt to hang over the mattress. A quilt intended to cover a bed may need different dimensions from a decorative top layer, and mattress depth, bed height, and personal preference all affect coverage. For a bed-specific reference, compare our Twin Mattress Dimensions and King Bed Dimensions pages.
Quilt-pattern instructions may also distinguish the finished quilt from the larger fabric pieces needed during construction. JOANN’s guide recommends allowing roughly 4 inches of extra fabric on each side during quilting; follow the measurements in the pattern you are using.
