by Blanket sizing confuses almost everyone because blanket dimensions do not correspond exactly to mattress dimensions. A "queen blanket" is not simply a blanket cut to 60x80 inches. This guide gives you actual finished dimensions for every standard blanket size and tells you which bed each one fits with proper side drape.
Complete Blanket Size Chart
| Blanket Size | Typical Dimensions | Intended Bed | Notes |
|---|---|---|---|
| Throw | 50" x 60" | Lap / sofa / twin drape | Not a bed blanket; decorative use |
| Twin | 60" x 80" to 66" x 90" | Twin (38" x 75") | Should have 10-12" drape per side |
| Full / Double | 80" x 90" | Full (54" x 75") | Also fits twin as luxury oversize |
| Queen | 90" x 90" to 90" x 100" | Queen (60" x 80") | 15" drape each side on standard height |
| King | 108" x 90" to 108" x 100" | King (76" x 80") | 16" drape each side on standard height |
| California King | 104" x 96" to 108" x 100" | Cal King (72" x 84") | Extra length for taller beds |
Throw Blanket Dimensions
Throw blankets average 50 inches wide by 60 inches long. Some run 60x70 or 60x80. They are designed for couches, chairs, and single-person warmth rather than full bed coverage. On a twin bed, a throw blanket can cover the top of the mattress but will have zero side drape and leave feet uncovered. Use them decoratively, not as a primary sleeping layer.
Twin Blanket Dimensions
Twin blankets range from 60 to 66 inches wide and 80 to 90 inches long. Given a twin mattress is 38 inches wide, a 60-inch blanket gives you 11 inches of drape on each side — acceptable but not luxurious. A 66x90 twin blanket is more comfortable, especially for adults on a twin. Check that the length exceeds 80 inches if you are 6 feet or taller.
Full/Double Blanket Dimensions
Full blankets run 80 inches wide by 90 inches long. A full mattress is 54 inches wide, so an 80-inch blanket gives you 13 inches of drape per side. Full blankets also work on twin beds if you want generous coverage on a smaller mattress — a common choice in children's rooms or guest rooms.
Queen Blanket Dimensions
Queen blankets are typically 90 inches wide by 90 to 100 inches long. A queen mattress is 60 inches wide, giving you about 15 inches of drape per side on a standard-height mattress. If your mattress is 12 inches or taller, the drape shrinks accordingly. For queen beds taller than 14 inches, look for a queen blanket in the 90x100 size or consider a king blanket.
King Blanket Dimensions
King blankets measure 108 inches wide by 90 to 100 inches long. A king mattress is 76 inches wide, leaving approximately 16 inches per side. See our full guide on king size blanket dimensions for a deeper breakdown including oversized and California King options.
Blanket vs. Comforter: What Is the Difference?
A blanket is a single-layer woven or knitted fabric. A comforter is a quilted cover filled with down or synthetic fill. Comforters are warmer but heavier; blankets layer well and are easier to wash. If you want to compare queen comforter sizing, note that comforters tend to run a few inches narrower than their same-label blankets because fill adds visual bulk.
