Today, we’ll be putting the spotlight on the smallest mattress size – the twin mattress! So, if you are living in a small space or with a little one, a twin bed might be your best bet. Also known as a single bed, it’s ideal for kids or single sleepers living in micro condos or studio apartments.

You can use a tried-and-true formula called The Golden Ratio, which means three to one, to figure out exactly how large your bedroom needs to be. Yes, designers have a few tricks up their sleeve. Case in point: a twin size bed runs about 3.17 feet x 6.25 feet in width and length, which takes up about 20 square feet. This means your room should ideally be at least 60 square feet, or just to be safe, 63 square feet (7’ x 9’).

Additionally, a twin bed—what we like to think of as a toddler mattress—is perfect for a bunk bed or a daybed. It’s also helpful to remember that a king mattress is the size of two twin mattresses combined.

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