Choosing the right storage unit size can feel overwhelming, especially if you’ve never rented storage before. Picking a unit that’s too small can lead to cramped conditions, while choosing one that’s too large may mean paying for space you don’t need. At Oakdale Self Storage, we help customers find the perfect storage solution by understanding what fits in each unit size and how to plan efficiently.

This guide breaks down common storage unit sizes and what you can typically store in each, making it easier to choose the right option for your needs.

Small Storage Units

Small storage units are ideal for boxes, seasonal items, and smaller personal belongings.

5x5 Storage Unit
Comparable to a small closet, a 5x5 unit can hold several boxes, seasonal decorations, small furniture, and personal items. This size works well for college students or anyone storing a few household items.

5x10 Storage Unit
A 5x10 unit offers space similar to a walk-in closet. It can fit a mattress set, dresser, small couch, bicycles, and multiple boxes. This size is popular for apartment residents or those decluttering a room.

Medium Storage Units

Medium units are suitable for storing the contents of an apartment or small home.

10x10 Storage Unit
Roughly the size of an average bedroom, a 10x10 unit can hold furnishings from a one-bedroom apartment, including mattresses, sofas, dining sets, appliances, and boxes.

10x15 Storage Unit
This size can accommodate the contents of a two-bedroom apartment or small home. Items may include furniture, appliances, boxes, outdoor equipment, and seasonal items.

Large Storage Units

Large storage units are best for whole-home storage, business inventory, or vehicles.

10x20 Storage Unit
A 10x20 unit can store the contents of a multi-bedroom home, including large furniture, appliances, garage items, and even a vehicle in some cases.

10x30 Storage Unit
Comparable to a one-car garage, a 10x30 unit is ideal for full household storage, commercial inventory, or long-term storage during a major move or renovation.

Tips for Choosing the Right Storage Size

• Make an inventory of everything you plan to store
• Stack boxes vertically to maximize space
• Leave walkways for easy access
• Choose a slightly larger unit if you plan to add items later
