We all like to think we only own “a few things.” Then moving day arrives and suddenly it looks like you’ve been running a secret furniture showroom. The truth? Choosing the right self-storage unit is less about guessing and more about being honest with your clutter.
Pick too small and you’ll be cramming boxes like Tetris. Pick too big and you’re paying rent for empty air. The sweet spot is out there — and this guide will help you find it. Or, if you want the shortcut, just plug your list into our Space Calculator and let it do the maths.
If your “stuff” is mostly cartons, luggage, or seasonal bits, a 1.5m × 1.5m unit (about the size of a walk-in wardrobe) is perfect.
Got a small flat or moving out of your share house? A 3m × 1.5m unit will do the trick.
Here’s where most customers land. A 3m × 3m unit gives you plenty of breathing space.
Moving an entire household or relocating interstate? That’s 6m × 3m territory.
Self-storage is perfect if you like to pop in and out of your unit. But mobile storage changes the game:
Mobile is often cheaper because it saves you truck hire and time. Compare both options here: Mobile Storage vs Self-Storage.
How many boxes fit in a 1.5m × 1.5m unit?
About 15–20 medium moving boxes, stacked neatly.
What size storage unit is best for a 2-bedroom apartment?
A 3m × 3m unit usually does the job.
Can I fit furniture in a 1.5m × 1.5m unit?
Only small pieces (chairs, nightstands). Larger furniture needs more space.
Do storage units have height?
Yes. At Storage Plus, units are 2.4 - 3.0m high. Stacking saves dollars.
Is mobile storage cheaper than self-storage?
It depends, but mobile storage often wins once you factor in truck hire and time.
