All The Mattress Sizes, in One Guide

A bed, aside from being one of most important pieces in the house, is also one of the largest and most significant furnishings you will own. This is why you should always purchase a bed that is the right size for your body and your room—this will definitely make things more comfortable.

Knowing what the standard sizes of mattresses are will help you decipher all those mysterious labels on your bed linen's packaging, like "Extra Long Twin," or "Eastern King." This will ensure that you will buy beddings that are a perfect fit.

So end the guessing game, whip out your measuring tape, and check out the list of mattress sizes below (sizes in text below are indicated in both inches and centimeters):

Youth Bed (33 x 66in or 83 x 167cm) and Single/Twin (39 x 75in or 99 x 190cm):

These bed sizes are good for kids to teens, although it would be more practical to get a single-size bed to last them for many years. When two single beds are placed side by side, these could also serve as an alternative to a King-size bed.

King Single (42 x 78in or 106 x 198 cm)

This is smaller than a double bed, but bigger than the standard single bed. This is a good option for restless sleepers who move a lot. Keep in mind though, that sheets of this size might be more difficult to find locally, compared to the standard-size single sheets.

Extra-long Twin (39 x 80in or 99 x 203cm) and Double/Full (54 x 75 to 80in or 137 x 190cm)

A double or a full-sized bed is meant for a single person. Although some couples would use this type of bed, take note only a 27-inch-space would be allocated for each person, which is too small compared to the standard 39-inch-width of a single bed.

Queen (60 x 75 to 80in or 153 x 203cm)

This is a good option for couples who like to cuddle, or if you have a small master bedroom, which cannot accommodate a King-size bed. A queen-size bed is also a good option for guest rooms.

King/Eastern King (76 x 80 in or 198 x 203cm)

This size of mattress or bed is roomy enough for two adults, although you have to make sure it will fit through your house’s doors or hallways (or even elevator, if you live in a condo) before you purchase it.

California King/Western King (72 x 84 inches or 182 x 213 cm)

This is lesser than the width of two single beds put together, although much longer, which is a good mattress choice for tall people. The sheets of this size, though, are also more difficult to find in the local market. Check for the sizes on the linen’s packaging.

Frequently Asked Questions

Is it important to know the dimensions of a mattress before purchasing?

Absolutely! One of your home's biggest and most significant pieces of furniture is the mattress. Knowing the standard sizes ensures you select the right fit, both for you and your room.

How can knowing mattress sizes help with purchasing bed linens?

Understanding the mattress sizes helps you decipher the sizing labeled on bed linen packaging, like "Extra Long Twin," or "Eastern King." This knowledge guarantees that you'll end up buying beddings that fit perfectly.

What are the ideal bed sizes for kids and teens?

Youth Beds and Single/Twin sizes are excellent sizes for kids to teens. If you want to make the most out of your purchase, buying a single-size bed is relatively more practical as it can be used for many years.

Can two single beds serve as a substitute for a King-size bed?

Yes, when two single beds are placed side by side, they can provide nearly the same amount of space as a King-size bed. However, the gap in between the beds may pose safety issues, especially if you have kids who will be using the bed as well. It may also imply more expensive prices as you have to buy two single bed linens, which are usually more expensive than one king-size bed linen.

Is it difficult to find sheets for non-standard bed sizes such as a King Single or a California King?

It might be more difficult to find sheets locally for non-standard bed sizes compared to standard-size single sheets. In this regard, you may need to have sheets custom-made or buy from stores that specialize in sheets for non-standard bed sizes.

What factors should I consider before buying a King or a California King mattress?

A King bed and a California King bed are roomy options for two adults. However, before buying, ensure that it will fit through your home’s doorways and hallways, or even your building's elevator, if you live in a condo.
