What is the difference between a twin and a twin XL?
Both are 38 inches wide. A twin XL is 5 inches longer (80 instead of 75), so it suits tall teens and adults. Two twin XLs side by side make a king.
How big should my bedroom be for a king bed?
Allow about 24 to 30 inches (60 to 75 cm) of walking space on each side. For a king that means a room at least 10 feet (3 m) wide.
