About this calculator
Renting a storage unit that's too small means paying for a second unit or leaving belongings behind, while one that's too large wastes money every month, and most people have no intuition for how self-storage square footage maps to a houseful of furniture and boxes. This calculator takes the number of rooms of belongings you need to store and suggests an appropriate unit size using commonly published self-storage industry sizing guides, the same rules of thumb storage facilities themselves use when advising customers over the phone. It's meant as a starting point for choosing between common sizes like 5×5, 10×10, or 10×20, useful when you're getting quotes or booking online before you've had a chance to physically see the unit, though actual space needed still varies with how much furniture you have versus mostly boxes, and how efficiently the unit gets packed.
Worked example
