When it comes to buying a mattress, it’s vital to determine the exact sizes you require. For example, if you’re seeking a replacement bed and also a new mattress together you’ll need to ensure that (1) It’s big enough for you to lie down on and comfortably move around, and (2) that it fits in the space you have allocated for it within your home. If it’s merely a swap out of old with new, you’ll need to ensure the new one’s measurements are in line with any existing bed sizes else you may end up with unsightly overhang or ledges.
Please check the mattress size chart below for the most common measurements and their names:
Mattress Size Names and Their Dimensions
Twin: 38″ wide x 74″ long
Unlike the name might suggest, oddly enough the Twin size is actually enough for one person and is often referred to as a Single (in the UK). The width is enough for an adult or child, but the length would suit anyone under 5ft 5″ tall. The Twin may also be sold in places as 39″ wide x 75″ long, so measure your base or existing mattress to be sure before you buy.
Twin XL : 38″ wide x 80″ long
The Twin XL is the same width as its smaller brother; the only difference is the length. Measuring at 6″ longer it can comfortably accommodate anyone up to 6ft tall. Although 80″ equates to 6ft 6″ it’s recommended that you allow for at least 6inches more than your height when laying down flat. You may also see this as 39″ wide in some cases like the Twin.
Full (aka Standard Double): 54″ wide x 75″ long
The Full is also known as a Double. Unfortunately though the term Double doesn’t quite suit this size because 54″ divided by two is 27″ of space per person, which is not much at all when sharing. The Full size, however, is an excellent option for single use. Like other mattresses of a similar length, this one would best suit someone under 6ft.
Full XL: 54″ wide x 80″ long
Like its little brother the Full XL is same in width, so still probably best for individual use; however, it’s slightly longer thus more comfortably accommodating taller people.
Queen: 60″ wide x 80″ long
The 60″ width of a Queen is plenty for an individual to sleep at any angle they desire, and if sharing, the 30″ each is also plentiful for a sound nights sleep without being too cramped. As you can see there is no shorter length version; it starts straight in at 80″ which is easily enough for the six-footers. Notice when you shop online that most websites will display by default the price of a Queen size until you change the selection. The Queen size is the most popular mattress size in the USA with approximately 47% ownership.
King: 76″ wide x 80″ long
One of the all-time favorites is the King size. Measuring in at a whole 16inches wider than the Queen size, the length may be the same, but the width is certainly something worth paying the extra money for. Provided you have enough bedroom space, the King is a recommended choice for sharing the bed while not having to sacrifice plush, luxurious comfort. The King size is one of the most common types in hotels worldwide. But, as for homes, is the second most popular mattress size in the US with 19% ownership.
California King: 72″ wide x 84″ long
In this chart, the California King is probably the second most popular size amongst couples in the US. Although it’s less wide than a standard King by 4 inches, it has the extra length accommodating comfortably for people over 6ft 6″.

Look for sheets that are maerkd as deep pockets. This means that they have a little more material in them for the really thick mattresses that are around now. These will give you the extra material you need. Don’t get the Twin XL, all that does is give you more length, not width.
My mattress measures 70″ wide, by 81 long by 10 ” deep. What size sheets should I buy? I was told it was a California King but the sheets are always too big..
Have to go King. Fitted sheet may be little snug but thats OK
I have a mattress that is a 70×76 with a 9 inch depth. I can not find sheets I need to fit. They fit one way but not the other. I keep buying and having to return because nothing fits. What size sheets do I need?
I have the same problem. All my King sheets are too big (wide)
Hi there, I have a camper mattress that measures 77” long x62” wide by 6” deep what size sheet set do I purchase? It’s a foam camper mattress.
Could you pl tell me if my mattress is 6.5 ft in height and 7.5 ft in width with a 16 in height ,what size sheet would fit . Thanks
Is there such a bed that’s 82″ wide?
No, only King and California King in the above dimensions, nothing in between.
Isn’t their such thing as an eastern king?
I have two King single electric adjustable beds that push together to make a bed 82 inches wide. I know I need two king single fitted sheets but can I buy top sheets a doonas anywhere?
I have a bed with size of width 6.5 ft and 7 ft length – mattress thickness is 1 ft, what size of bed sheet should I purchase?
You could try a California King, but don’t get fitted because it will already be slightly too small in width but correct in length.
If its 6 x 6.5 in width, that is called European King.. Or Super King. Mostly Asian/European countries have that size. Bedbath and Beond has a Wamsutta sheet brand that has 1 bedsheet option for that size in several colors. Good quality but expensive.
My mattress is 77 in length, 80 wide and 8 in depth. What size sheets do I need? When I buy queen they’re too small but king are way too big!!!
It sounds like you have a King size so stick with the King sheets. Perhaps try tucking / folding the sheets under the mattress in between the box spring / bed frame.
You seem to be very knowledgeable. I just bought I guess a European queen 57 by 77 and the height of the mattress is 13.5 inches tall..not sure what sheets to buy. Nothing is “normal ” about it 🙁
Is it from IKEA?
I am replacing mattresses in my rv.
Bed-72×59
And 48×76
And 29×76
What size did you replace the 59×72 with? I’ve got to replace my camper mattress and I don’t even know where to begin.
I just ordered a 8 inch twin mattress and box spring. Is this a normal size twin. Can’t seem to figure it out.
Hi, my family has a sofa bed in our guest room where the mattress is 52″ wide, 70″ long, and 4 1/2″ deep. Can you please advise what size sheets would fit it? We’ve tried them all at this point I think. Twin & full were too small, queen and king were too big. I’m beginning to think that maybe it requires specially made sheets?
OMG, I have a sofa bed, EXACTLY that same size that I am searching for replacement sheets for….no luck……have you had any success since this posting?
For thin mattresses, I would go for two top sheets, instead of trying to find a fitted sheet to fit snugly. I am old, so I grew up with straight sheets and learned to make “hospital corners” on the bottom sheet the way they do in the military. Google it for the method. If you do it right, the corners stay tight for a week. You can also get “sheet garters” to keep the corners snug when using a flat sheet as a bottom sheet.
Have you tried DOUBLE sized sheets?
Yikes – 79 inches long, 74 inches wide and 9 inches deep. Is it a European sizing?
Is there a bed that is 48in wide and 80in long?
What size is a 74 wide and 77 long
Was told it was a California king?
I have a sleep sofa mattress that measure 6′ x 5′ (72 x 60) What would you consider this?
I have a hospital bed. I need a mattress for it I was told I could get a twin size 79″ length x 36″ Width would that work? Help please?
Hospital bed mattresses are normally extra long twins which measure 39″ x 80″.
Looking for a replacement mattress for our camper bed. It’s dimensions are 72” long and 60” wide what options are there to replace it with that will fit! Don’t mind going a few inches longer either way. But don’t want to go smaller.
Have the same size 80″ x 36″ hospital style bed – wondering the same thing!
Full XL 53″ x 80″
seriously the hardest bed to find a frame and sheets to fit, what do you guys use for frame or sheets?? google isn’t helping! that’s a first. : (
The proper fit would be an extra long full size sheet. Make sure the thickness of your mattress is within the specified sizes on the label (if yours is 10″ the proper label should say something like ‘for mattresses 8’ to 12″‘. People should not be fooled by “deep pocket sheets” if it doesn’t have a height range it could be any height,
Any twin/full frame will work, even twin, full, queen is fine, remember a standard frame doesn’t go all the way to the end of the mattress.
I need sheets for mattress 14 depth 78 length 39 width
Hi Barbara,
It sounds like you need some fitted sheets for a Twin XL. We don’t stock or supply these items, but you could perhaps find some by running a search on Amazon.
Kind Regards
My Terpurpedic mattess purchased in the US several years ago measures 72″ Wide and 77″ long measuring only the top of the mattress itself, not including the 4 sides. None of these descriptions seems correct. Is this a king or cali king or super king? What sheets should I buy?
Hi Claudia,
The size you mention matches that of an RV Mattress. However for clarification and further advice you could try calling Tempurpedic Customer Services on 800-821-6621. Hope this helps.
My bed measures 65 wide × 82 long and I can’t figure out the exact size is it a queen or king no luck finding answers
Hi Mary,
For the bed dimensions that you have provided, you will need to buy an Olympic Queen size mattress, which measure at 66 in. x 80 in.
Hope this helps.
Will there be any bed with dimension of 120 inches length, or more than 120 inch, and 25 – 30 inch width, if so where can I buy them?
This seems like an extremely long length, it’s not a size that I have come across
I’m about to get a new bed and it’s 60″ W x 14″ H x 80″ D I got queen fitted sheets that are 60” W x 80” L x 12” Depth will they fit? It’s a serta perfect sleeper
So we bought an icomfort twin xl, 2 infact to go with our split adustable base. The length was supposed to be 80, but my husband is hanging off. We measured it and it’s only 76.5 in long. Is it a defect, or should we pick an entirely different mattress?
Considering the amount of shortage it may well be a defect. Raise it with their customer support team for clarification.
Hi Lindsey! I need to get sheets for my queen pillow top bed..I’ve measured it with just the bed and 3” My Pillow topper… it comes to 17 “ (I need the extra because have had back surgery) I’m having a custom linen sheet made because I can’t do the struggle of having to buy a king that’s too big! do I get the pockets 21” or 22”?
Thank you so much!!!
Hi Charlene,
This is a tricky one. I would go with 22″ to begin with and if it needs altering it would be easier than falling short with a 21.”
Hope this helps.
If the mattress is 60″×75″ is it a queen or a full
Our mattress is 78 x 78 x 10 (Inches). We are so eager to find fitted sheets. Tucking in the sheets has not been successful!
Hi. i’m having the same problem. It also measures 78 x 78 ” and we can’t find any fitted sheet anywhere to that size.
Where did you find you 78X78 Mattress? I have one, or actually it’s 2 twin beds put together by a strap, and I’m looking for a mattress that will fit? but I can’t find that size? a ‘king’ is either 76X80, or 76X82?
Carla
Hi Lindsey! I’ve imported mattress from Asia, which measured Width 42″ Length 78″, Now, I am looking for Box spring or bunky board for it, the closest I got was Twin XL, can you please suggest ? Thanks
Rgds
Did you ever find fitted sheets? My bed is 78 x 78 and it’s IMPOSSIBLE to find any and anything I buy SUCKS lol! We have to readjust and re-strap the sheets EVERY DAY over and over again!!!!!!
My bed is 78×78 I found super soft jersey sheets at Walmart that fit! They feel like a vintage T-shirt and stretch like you wouldn’t believe!
More and more of us are needing “hospital” beds at home, and their mattresses are only 36″ wide. That’s not too bad, for a twin fitted sheet – except that the length of the mattress exceeds the sheet by at least 4″! Is any bed linens maker paying any attention to that? Just because they’re hospital beds doesn’t mean they are only used in hospitals, or that we should have to put up with plain white sheets and pillow cases. I like pastel florals – others might like plaids, stripes, geometrics, paisleys, what-have-you. Older patients don’t need to be “reminded” that they’re in hospital bed all the time – color and patterns help elevate the mood.
I have a bed 42 wide, 80 long, and 6 deep. Please tell me where to find sheets for it and where its made?
We have twin beds and the mattress is very thick. All of the fitted mattresses come off. Please help. Thank you.
The twin XL 80” L fits in a twin bed measuring 85” L, right?
Yes, but as you can imagine there will be a 5-inch gap at one end
Is there a mattress size 43 BY 78 for antique bed
This seems like a non-standard size, and you’ll probably need something custom-made for it.
I have a sofa sleeper that mattress measures 60 wide and 70 long, is there any replacement mattress that size available?
I’m replacing a mattress, a 1988 Sealy folding couch. The length is 70″ and that’s no problem. The width of the frame fits a 61″ mattress, but it is a lot cheaper if I go with a 60″ (it is supposed to be queen size). Is there any problem using a mattress that is just a little smaller than the frame size? Thanks for the info.
We have a Super King bed that we brought from overseas. We want to replace the mattress but having a hard time finding one. Any suggestions where to look?
What are the dimensions of your current mattress?
We are looking for a bedframe for our current set of box spring/ mattress. The mattress measures 78×78. I’m having a hard time finding a frame that fits. What is the “name” for this size?
I’ve not come across this size before. When and where did you purchase the mattress? It could be custom-built or imported from outside the US where sizes can vary.
I have a bed that measures 4 1/2 wide by 60 inches long. What size is this??
Where can I order a 52″ X 73″ mattress?
Following for an answer. I need to find a mattress this size too for an antique bed
My mattress is 72W X 80L. I have tried both King and California King size sheets and neither fit. What size sheets do I need?
I have a twin trundle bed…the length of it is 74 inches. It is a four sided “box”, not an open slat bed. I can only find mattresses that are 74 inches long. I am assuming that will not fit?
It might be a tight fit, but you should get an inch or so to play with, especially if it’s an all-foam mattress. Could potentially squeeze in..
Help! Where can I find a bed frame for 78×78 mattress and what is this size called??
Hi, where can I find mattress with size 28” wide and 69” long?
I have a mattress that is 80 in x 42in. Which sheets? Super single waterbed sheets re close but they don’t fit the depth of this mattress.
I have purchased a king mattress that measures 76 wide 82 long. All the sheets I have try are too tight. Is it a king? Any suggestions?
76 x 80 is a King, not 82″
How tall is the mattress?
