How Big is a 10x10 Storage Unit?

A 10 x 20 storage unit is 10 feet wide and 20 feet deep, giving you around 200 square feet of floor space. In metric terms, that’s roughly 3.05 metres by 6.10 metres, or about 18.6 square metres. Most units have ceilings about 8 feet high, providing about 1,600 cubic feet of total storage space (about 45 cubic metres).

Picture a standard garage or a roomy home workshop. A 10x20 storage unit gives you space for the contents of a three to four-bedroom home (furniture, appliances, bikes, and plenty of boxes) with room left to move around if you plan your layout smartly.

You can usually fit between 120 and 200 medium boxes in a 10x20 storage unit, depending on how much furniture or other large items you store. Sticking to boxes of the same size helps you stack neatly and make the most of the height, while a mix of shapes will reduce the total count.

Leave a small gap between stacks so you can reach items without needing to move everything around.
