What Is the Cheapest Storage Unit Size? (2026 Guide)

The cheapest storage units are typically 5x5 units, which are roughly the size of a small walk-in closet.These units are designed for small items such as boxes, seasonal decorations, clothing, or small furniture.

In many cities, 5x5 storage units start between $40 and $80 per month, although prices vary depending on the facility, location, and availability.

Why smaller units cost less

Storage facilities price units based largely on square footage.Because a 5x5 unit only contains 25 square feet, it requires less space inside the facility and is therefore cheaper to rent.

However, smaller units can fill quickly at busy facilities, which sometimes causes prices to increase faster than larger units.
