What storage unit sizes usually fit
A 5x5 unit is closer to a large closet and works best for boxes, decor, small furniture, or a few seasonal items. A 5x10 can work for a studio or small one-bedroom move. A 10x10 is a common planning size for many one- to two-bedroom homes, while 10x15 and 10x20 units are better starting points for larger households or moves with substantial furniture.
If your storage plan includes many boxes, heavy furniture, or items that cannot be stacked, compare this estimate with the Moving Box Calculator before reserving space.
When to choose a larger unit
- You need to walk inside the unit and reach items later.
- You have sofas, mattresses, dining sets, desks, patio furniture, or exercise equipment.
- You have many fragile items that cannot support stacked boxes.
- You are storing items for several months and want a less compressed layout.
How to pack a storage unit efficiently
- Place the heaviest, sturdiest boxes on the bottom.
- Break down tables, bed frames, and shelving when possible.
- Use vertical space, but avoid stacking weight on fragile items.
- Keep labels facing outward and create a simple aisle if you need access.
- Put tools, cleaning supplies, seasonal items, and frequently needed boxes near the front.
Common storage planning mistakes
The biggest mistake is choosing a unit that only works if everything is packed perfectly. Real items have odd shapes, and moving day is rarely perfect. Leave room for awkward furniture, last-minute boxes, and safe lifting. If the estimate feels tight, move up one size.
