How to Choose the Right Size
The right bed size largely depends on your personal sleeping habits, your room size, and whether you sleep alone or with a partner. A smaller bed leaves more floorspace, but it also is more cramped.
Factor #1: Your Height and Sleeping Habits
Height is an important consideration, as you want to avoid your feet hanging off the edge of the mattress. Consider a Twin XL, Queen, or King if you are taller than average. If you enjoy sprawling out while sleeping, a Full, Queen, or King bed may be a better choice.
Factor #2: Your Room Size
Measure your bedroom before making a purchase to ensure the bed will fit comfortably without overcrowding the space. Leave enough room to walk around and place other furniture, such as nightstands and dressers. If your bedroom is on the smaller side, opt for a Twin or Full bed to maximize space. For larger master bedrooms, a Queen, King, or California King can make a statement.
Factor #3: Whether you Sleep With a Partner
If you sleep with a partner, a Queen or King bed is generally recommended. These sizes provide enough space for both sleepers to move around comfortably without disturbing each other. If one or both partners tend to sprawl out, a King or California King bed may be the best option.
