This post is the second part of a series on the four most common mattress sizes—twin, double, queen and king—on the market. You can also read our entire Bed Sizes Canada: Mattress Dimensions and Size Guide.

Are you a young professional who has just moved out on your own? Or a parent with adult children who have finally left home? Whether you’re thinking of surprising them with a new mattress or dreaming of the endless possibilities for your new guest bedroom, a double bed may be the best fit for you. Also known as a full bed—a term popularized in the 1870s—a double bed is considered a good starter mattress. It’s a great option for single sleepers with limited space or couples who like to cuddle. Although a double bed is 16 inches wider than a twin mattress, it’s not quite large enough for couples who like to sprawl out or invite kids and pets into bed.

But that wasn’t always the case. Take a look back in time and you will see that double beds were once the mattress of choice among couples. In fact, most Americans were sleeping on twin and double size beds well into the 1940s. It wasn’t until queen and king size beds entered the scene in the late 1950s that shoppers realized they had bigger and better options. Oh, much has changed.

Today, a Double size bed, which runs 4.5 feet x 6.25 feet in width and length, occupies about 28 square feet, so your bedroom should ideally be at least 110 square feet (10’ x 11’).

Here, a closer look at Double size bed dimensions.

Double bed size in inches: 54” x 75”

Double bed size in cm: 137.16 cm X 190.5 cm

Double bed size in feet: 4.5 feet x 6.25 feet

Comfortably fits: 1 person with a pet, 2 adults, no pets

Dimensions: 54 x 75 in OR 137.16 X 190.5 cm

Great for older children who are outgrowing their twin bed, young adults, guest rooms, or two sleepers who enjoy cuddling.

Not so great for taller individuals, two sleepers where one or both move around or like to spread out when they sleep, couples who wish to sleep with their pets.
