Well, honey, technically, twin XL sheets are longer than regular twin sheets, so they might hang off the end a bit on a regular twin bed. If you don't mind a little extra fabric draping over the sides, then go for it. But if you're a stickler for a perfectly fitted bed, you might want to stick with the right size.
They will fit if you will have to tuck the extra length in at the bottom.
No.
A regular twin bed is only 74 inches long. An XL twin is 80 inches long. So the answer is NO.
Yes, the only difference is 5 inches. It will definitely fit.
No, they will be too short. A Cal King sheet would fit on both twin beds, if they are pushed together.
Water bed sheets are special because they attach from top to bottom. Regular fitted sheets cannot be easily used on water beds because the bed is too elastic for them to fit on.
There are different types of bunk beds, on the regular ones it won't fit
When you say mattress that is the top. Boxspring is the bottom. So im guessing you have mattress and boxspring extra long. The answer is yes. A twin extra long mattress will fit a regular twin bed frame. The length is just longer not the width.
A couple can't fit in a twin size bed. Only one person can.
No
A Twin XL fitted sheet will not fit a queen size bed properly. Twin XL sheets measure 39 inches by 80 inches, while queen size beds are 60 inches by 80 inches. The width of the Twin XL sheet is too narrow to cover a queen mattress adequately, leading to a poor fit.
No. Two twin size mattress will fit a king size bed frame.
