The main difference between king and full mattresses is in length and width. A king size mattress measures at 76 x 80 inches. A full size mattress measures at 54 x75 inches.
Couples that share a bed often struggle with a common problem: getting enough space to sleep comfortably. If one partner tosses a lot in their sleep or likes to stretch out, this can cause serious issues about sharing the space equally.
Keep in mind mattress sizes can vary by an inch or two from brand to brand. In this guide, we will cover key differences in king vs full-size mattresses so you know which is best for you.
As stated previously a king mattress measures 76 inches by 80 inches, and it’s one of the largest commercially-available bed sizes. Because of its luxurious size, it’s a popular choice for co-sleepers and restless sleepers. This is also recommended for those who want more personal space as they sleep, as couples can have more room to stretch out away from the bed’s edges.
A king-size bed is the best choice for couples that want to have extra room, particularly if they’re sharing a bed with children or pets. It’s also ideal for those who change sleeping positions throughout the night, as the extra space will prevent them from falling off the edge in their sleep.
If you live in an open-plan living space, a king-size bed can also double as a luxurious focal point. Because you aren’t constrained by walls, you’ll have more room for this spacious bed size.
A full mattress, or double bed, measures 54 inches by 75 inches. These beds are smaller than queen-size beds but wider than twin-size beds by 16 inches. Full-size beds used to be the bed of choice for American couples in the 1940s, until queen and king-size beds were introduced in the 1950s.
Bedframe and mattress manufacturers typically recommend full-size beds for rooms that measure at least 10 feet by 10 feet. This gives an extra two to three feet of free space for walking space and furniture.
Full beds are best for solo sleepers or couples that like to cuddle while they sleep. Young adults, older children, and teenagers may also find full beds to be a spacious transitional bed size.
There’s plenty of room if only one person is sleeping on this type of mattress. This makes them a popular choice for guest rooms, dorm rooms, and studio apartments. However, if you like a little more personal space or need more leg room, this may not be the mattress size for you. Instead, you may want to opt for a larger size, such as a queen or king bed.
Taller individuals who don’t need the extra width may instead decide between a full and twin XL mattress since twin XL beds offer five more inches of length than full beds.
A king-size bed is the best bed for couples that prefer to have extra room while they sleep, especially if they’re sharing the bed with a pet or child. But for single adults, older teens, or those with smaller main bedrooms, a full-size bed is just the right size.
Getting enough hours of good-quality sleep is important for your physical and mental well-being. If you don’t have enough space on your bed to sleep comfortably, it may be time to upgrade to a larger mattress.

Yes, you can fit queen-size sheets on a full-size bed. Keep in mind that because a queen-size bed is slightly longer and wider than a full-size bed, you’ll need to tuck the excess slack material in. You can also hold them in place with elastic sheet straps.
Couples sleeping in a full-size bed will have 26.5 inches of sleeping space per person. This may be a tight fit, especially if co-sleepers are taller or have larger body frames.
Yes, a double bed and a full-size bed are the same. Full-size beds are commonly called “doubles” because it is commonly thought that full-size beds are twice as long and wide as twin beds. But, in reality, a full-size bed is 16 inches (a little under 1.5x) wider than a twin-size bed.
