How to know if a 10x20 is enough

If you are deciding between a 10x15 and a 10x20, think about the total number of rooms, the size of your biggest furniture, and whether you are also storing garage or patio items.When in doubt, the larger unit can sometimes save more money than expected if it prevents a transfer, a second unit, or a stressful repack later.
