Questions about this tool
What is the difference between a US Queen and King?
A Queen is 60 × 80 in (152.4 × 203.2 cm) and a King is 76 × 80 in (193.04 × 203.2 cm), so the King is about 40 cm wider.
Which double sizes are common in the Gulf?
Metric sizes such as 160 × 200 and 180 × 200 cm are common, and some shops call them Queen and King.
Is the bed size the same as the mattress size?
No, the frame is a few centimeters larger. Use the mattress size for sheets and the frame size for room planning.
