Comfortable, attractive, and the right size bedding is a must have for your dorm room at college or boarding school; comfortable and right sized for a good night's sleep and attractive to create an anchor for your dorm room decor. Before moving to campus, let's make sure you are prepared to select the right size bedding.

How big is your dorm room mattress?

Before purchasing dorm room bedding for college or boarding school, it is important to know the size of the mattress. It is best to obtain your dorm room mattress size directly from your campus housing office to avoid costly mistakes.

Most common mattress sizes found in dorm rooms:

  • Twin Mattress = 39 x 75 inches
  • Twin Extra Long Mattress = 39 x 80 inches (Commonly referred to as twin XL, TXL, extended twin, or extra long twin.)

Common mattress sizes found in campus apartments or surrounding housing:

  • Full Mattress = 54 x 75 inches (Often referred to as a double bed.)
  • Queen Mattress = 60 x 80 inches

DormSmart Tip: From researching more than 2000 housing websites each year, we have found that there is no consistency in mattress sizes from campus to campus. On some campuses the mattress size changes between rooms and floors of the same residence hall so it's important to check directly campus housing office before investing in bedding.

Common Sheet Sizes

The measurements below are for fitted sheets and will help ensure a proper fit onto your dorm room mattress. These dimensions can also be used as a guide for mattress pads and covers.

  • Twin Sheets = 39 x 75 inches
  • Twin Extra Long Sheets, commonly referred to as twin XL or TXL =  39 x 80 inches
  • Full Sheets =  54 x 75 inches
  • Queen Sheets = 60 x 80 inches

Live Dorm Smart Tip: Because there is 5 inches difference in length between a twin and twin XL mattress, the most important detail to remember is a student's fitted sheet must be made to fit the mattress in their dorm room. Tucking a fitted sheet that is too long or stretching a fitted sheet that is too short will most likely leave a student sheet-less in the middle of the night. A standard twin flat sheet is 66" x 96" and will fit either a twin or twin extra long bed. To save money, if a student's needs a twin XL sheet set, they can always use their twin flat sheet and pillowcase from home then purchase a twin XL fitted sheet to complete the set. Remember to account for the depth of the mattress and padding when purchasing a fitted sheet.

Mattress Depth

Before selecting your sheets and mattress pads, it is important to know the depth of your mattress in your dorm room. Below are common mattress depth dimensions to use as a guide.

  • Standard = 7 to 9 inches
  • Deep = 10 to 15 inches
  • Extra Deep = 16 to 22 inches

Live Dorm Smart Tip: Be sure to account for the increased depth of a foam topper. A good foam topper can create an additional two or more inches of depth to account for when purchasing a fitted sheet for your mattress. Never purchase sheets without knowing their depth (pocket size).

Mattress Pad Depths

Because many mattress pads fit onto a mattress like a fitted sheet, it's important to purchase a pad that fits the depth of your mattress as well as the length. Below are common mattress pad depths to use as a guide:

  • Standard = 7 to 14 1/2 inches
  • Deep = Up to 15 inches
  • Extra Deep = 16 to 22 inches

Comforters

Listed below are the dimensions of most comforters to use as a general guideline. These are approximate sizes. Some manufacturers may run slightly smaller or produce oversized comforters to fit both a long and short mattresses.

  • Twin = 68 x 86 inches (At DormSmart, comforters and duvet covers below 90" are sold as twin size.)
  • Twin Extra Long, commonly referred to as twin XL or TXL = 68 x 90 inches or longer
  • Full = 80 x 90 inches
  • Queen = 86 x 94 inches

Live Dorm Smart Tip: While a twin XL comforter is preferable for 100% coverage, some students may have no alternative but to take their twin comforter or duvet from home and make it work. The best way to make a twin XL bed with a twin comforter is to pull the length of the comforter toward the foot of the bed to add a few inches then make a small fold at the top (like turn down service) and fill in any gaps with pillows. Pillows are a must have to turn your dorm room bed into daytime seating

If you plan to raise your bed with bed risers, purchasing a full or queen size comforter or duvet to accommodate the increased height is an option (just make sure the pattern works, a solid color or a pattern that repeats versus a border pattern works best). Since most dorm room beds are against the wall, you can adjust your bedding to the desired width (side length that is showing). A queen size comforter, 90" or longer, works best on a raised twin XL bed and a full size comforter, approximately 86 or 88" long, works best on a raised twin bed.

Down Comforters

Listed below are the dimensions of most Down Comforters to use as a general guideline. These are approximate sizes.

  • Twin = 68 x 88 inches
  • Twin Extra Long, commonly referred to as twin XL or TXL = 68 x 90 inches or longer
  • Full/Queen = 90 x 90 inches or longer

Live Dorm Smart Tip: Because your roommate may be allergic to down, consider purchasing a down alternative or hypoallergenic down comforter for your dorm room bed. Some manufacturers now process down to be hypoallergenic. It will feel just as good without the allergies.

Blankets

Blanket sizes can vary from manufacturer to manufacturer. Listed below are the general dimensions; most blankets should fall close to these sizes.

  • Twin = 66 x 90 inches (A twin blanket will fit a 39 x 80 inch twin extra long mattress.)
  • Full/Queen = 90 x 90 inches
  • Throw = 50 x 60 inches

Duvet Covers

Listed below are the dimensions of most Duvet Covers to use as a general guideline. Duvet covers are easy to clean, protect your comforter, and can easily change the look of your dorm room decor! Just remember when selecting a duvet cover for your dorm room bedding, be sure to match your comforter's size as closely as possible to the duvet cover size.
  • Twin = 68 x 88 inches
  • Twin Extra Long, commonly referred to as twin XL or TXL = 68 x 90 inches or longer
  • Full/Queen = 88 x 88 inches (can vary by a few inches)

Note About Bed Skirts

Twin extra long (commonly referred to as twin XL or TXL) bed skirts can be difficult to find but do exist. A standard twin bed skirt will leave a gap at the head of the bed but can be used. Another option would be to raise your bed with bed risers and purchase a decorative under bed storage solution that coordinates with your bedding. It is practical, fun, and makes a statement. Also, consider using a flat sheet as a bed skirt or a purchasing a larger size duvet/comforter (see note under Comforters).
  • Twin Bed Skirt = 39 x 75 inches
  • Twin Extra Long Bed Skirt = 39 x 80 inches
  • Full Bed Skirt = 54 x 75 inches
  • Queen Bed Skirt = 60 x 80 inches

Live Dorm Smart Tip: A standard bed skirt has a drop ranging from 14 or 15 inches. Bed skirts are also available with 18" and 21" drops to accommodate the additional height of a raised dorm room bed.

Pillows

Dorm living requires many pillows! The right pillow provides a good night's sleep while all those extra pillows turn your bed into a piece of furniture for additional seating during the day. Remember, your dorm room is a complete living space so make use of pillows and remember to order extra pillowcases to coordinate.
  • Standard = 20 x 26 inches (uses a Standard size pillowcase)
  • Queen = 20 x 30 inches (uses a Standard size pillowcase)

Live Dorm Smart Tip: If you like your pillows to look full, order queen pillows with standard pillowcases.
