Race Car Bed Mattress Size Guide: Twin vs Toddler

What size mattress fits in a race car bed?

Most race car beds are built for a standard twin mattress, which measures 38 inches wide by 75 inches long. Many popular kid-sized race car frames use this exact footprint so a typical twin mattress (or twin-size foam mattress) drops in without cutting, bending, or special ordering.

That said, race car beds aren’t all identical. Some are designed around a twin XL (38 x 80 inches) for extra legroom, while others use a crib/toddler mattress (commonly 28 x 52 inches) for younger children. The quickest way to confirm is to measure the inside of the mattress cavity (where the mattress actually sits), then match those measurements to standard sizes.

How to measure your race car bed for the right fit

Measure the interior length and width of the platform or side rails, not the outside of the “car” shell. If there’s a footboard or molded bumper, measure between the stops where the mattress will rest. Also check the recommended mattress height—some race car designs have tall sides, and a mattress that’s too thick can sit above the rails and reduce the “tucked-in” feel.

Common mattress sizes used in race car beds

Twin (38 x 75): The most common choice for race car beds.

Twin XL (38 x 80): Less common, but appears in a few larger frames.

Crib/Toddler (28 x 52): Used in smaller, toddler-focused race car beds.
