What size blanket should I get for a double or queen-size bed?

• Double Bed: Standard double blankets measure roughly $220\text{ cm} \times 210\text{ cm}$. This size provides a perfect drape over the edges of a double mattress.

• Queen & King Beds: For larger mattresses, opt for a queen/king size blanket (typically $220\text{ cm} \times 240\text{ cm}$ or larger). This ensures there is plenty of overhang on the sides so nobody is left out in the cold at night.
