Measure Your Space Along with floor space, determine ceiling height, too. Leave at least two feet of space between the bunk bed and the ceiling to prevent bumps. While bunk bed heights vary, the average bunk is usually between 5 1/2 and 6 feet tall.Click to see full answer. Considering this, how high should ceilings be for bunk beds?A regular bunk bed, with comfortable amount of space between the bunks, goes up to the height of about 65 to 75 inches; since the standard height of the ceiling is 8 feet, in most rooms there will be no problems — except, of course, if the person sleeping on the top bunk is 7 feet tall.Subsequently, question is, how tall is the average bunk bed? The most popular heights for bunk beds are children’s 65″, 68” high bunk beds and 70” to 72″ high bunk beds. Though it comes down to preference, the criterion to consider when deciding on how high your bunk bed should be; is the age of your children and the ceiling height of the room/ safety. Also asked, how much headroom do you need for a bunk bed? The headroom is 28in (71cm) which is adequate for up to 9 years old. If you had some sloping ceiling in addition to the standard room height you could build an arrangement with more headroom.What age is OK for bunk beds?Yet, if your child is only 3 or 4 years old, you may be wondering if he or she is the right age for bunk beds – and, if so, which bed is the safest choice. The American Academy of Pediatrics (AAP) recommends children under the age of 6 not be allowed to sleep in the top bunk.
