Beds in college dormitories are extra long to better suit young adults, this longer mattress requires longer sheets and a longer comforter. Make sure your extra long comforter (XL) measures at least 92 inches long in order for your comforter to fit your twin xl bed. Many stores and online retailers will make false claims their comforters are "Twin/Twin XL" and will not list the dimensions of the comforter, if you see this turn and run away fast. These comforters are generally the smaller typical Twin size and will not fit a bed in college dorm rooms. We carry only true Twin XL comforters, sheets, and bedding sets. All of our comforters will at the very minimum measure 92 inches long and our sheets will fit XL mattresses 12 inches thick or larger.
