This post is the fourth and last 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.

Is your heart set on a King mattress?Whether you are moving into a new home or thinking of giving your bedroom a makeover, we understand you may have a lot on your mind. The king mattress, which runs about 6.33 feet x 6.67 feet in width and length, is best for couples who like to sprawl out or share their bed with kids (or pets—because hey, what furry friend wants to be left out?) Considering it’s 16 inches wider than a queen size bed, make sure your bedroom is fairly spacious and at least 144 square feet (12 x 12).

This means you’ll get the same thickness, firmness, and support, regardless of size.
