US Queen
When considering bedding for an American Queen size bed, it's important to note that it measures 60" wide and 80" long.
On the other hand, a UK King size bed measures 60" wide and 79" long.
However, due to the slight difference in length, UK King bedding can still work well on an American Queen bed.

UK King:
150 x 200cm (5’0 x 6’5”)

150 x 200cm (5’0 x 6’5”)
US King Size Bed:
