What Factors Should I Take Into Account When Selecting a Mattress Size?

Other than pricing, the first thing you’ll probably think about while searching for a mattress is what size will work in your room. The solution is simple: Keep your current mattress size if you already have a bed frame, sheets, and duvet you like and are pleased with how much space your bed takes up.

However, you should carefully examine which standard mattress size suits your needs and tastes to scale up to something bigger or buy a bed for a growing child.

When purchasing a new mattress, take into account the following variables to determine which mattress size best suits your needs:

Room Dimensions: Measuring the room’s length and width is useful for determining what size mattress will fit in your room. You can use a regular or digital tape measure on your phone to acquire an approximate measurement. Once you have precise measurements, choose the best mattress size that matches the space. Don’t forget to take the size of the bed frame and other furnishings into account as well.

Sleeping Persons: A full-size bed may be ideal for one person, but it might become uncomfortable with two people and one or more pets. Consider a king-size or larger bed if you have pets or young kids who constantly climb into bed.

Sizes of Sleepers: A queen mattress should be fine for most adults. However, a king or California king may be preferable for those who toss and turn a lot or are significantly larger than average in both dimensions. Non-standard mattress sizes, such as the Olympic queen and the Alaskan king, offer more space than the traditional king and California king.

Sleeping Positions: While most of us have a preferred sleeping position—whether on our back, side, or stomach—we sleep in various positions. This implies that you could wake up on your side even if you go to bed on your back. When choosing a bed size, consider how much space you may require to spread out or move around at night.
