What Size Storage Unit Do I Need for Moving? (2026 Guide)

The simple answer

The right storage unit size for moving depends on how much of your home you are storing, how long you plan to keep it there.Also whether you are packing just boxes or also storing furniture and appliances.For many moves, renters usually choose one of these sizes:• 5x10 for a small move or partial apartment• 10x10 for a one-bedroom apartment• 10x15 for a two-bedroom apartment• 10x20 for a three-bedroom house or larger move

Why moving storage is different

Storage for moving is different from long-term overflow storage because you often need to fit an entire room, apartment, or house into the unit all at once.That means the biggest furniture pieces usually matter more than the total number of boxes.

Common moving situations and unit sizes

Here are common starting points renters use when moving:• Studio or very small apartment: 5x5 or 5x10• One-bedroom apartment: 10x10• Two-bedroom apartment: 10x10 or 10x15• Three-bedroom house: 10x20• House plus garage items: 10x20 or larger

What makes people choose the wrong size

The biggest mistake during a move is underestimating how much space furniture, mattresses, and bulky boxes take up.A moving storage unit fills much faster than people expect once couches, dressers, appliances, and dining sets are involved.

When to choose the next size up

If you are between sizes, the safer move is often to choose the slightly larger unit when:• You have oversized furniture• You are storing appliances• You have a lot of boxes• The move is stressful and you do not want to pack tightly• You may add more items laterPaying for a bit more space can be cheaper than needing to transfer to another unit later.

What moving storage usually costs

The monthly price depends on the size you need, your city, and whether the facility later raises rates.Typical price ranges often look like this:

SizeCOST
5x10$60 to $120/month
10x10$100 to $180/month
10x15$140 to $240/month
10x20$180 to $320/month

The real long-term cost can be higher once insurance, fees, and price increases are added.

How to estimate your moving storage size

The easiest way to estimate the right size is to focus first on your largest items: beds, couches, dining tables, appliances, and how many total rooms are being stored.If you are not sure, use the size finder instead of guessing.
