Choosing the Right Storage Unit Size

KEEP THIS IN MIND

Unit dimensions, access routes and the way you pack can change what fits. Treat size comparisons as a starting point and ask the facility team when in doubt.

Choosing a unit is easier when you start with what you need to store, not a number of square feet. Make a simple list, note the largest items and decide how often you will need to reach them.

Start with the largest items

A sofa, dining table, mattress or commercial shelving usually determines the footprint. Measure those pieces first, then add sealed boxes around them. Leave a narrow aisle if you expect to visit the unit regularly.

Use familiar room comparisons

A 25 sq ft unit can hold the contents of a compact studio or student room. Around 50 sq ft suits many one-bedroom flats, while 75–100 sq ft is a practical starting point for a two-bedroom move. These are guides, not guarantees.

Ask before you overbook

Photos and a short inventory are often enough for our team to recommend a sensible option. If your needs change, ask about moving to another unit rather than paying for unused space.
