One of the most important considerations when renting a storage unit is finding the right size. You want to ensure you have enough space to store all your belongings without paying for extra room. But how do you determine what size storage unit you need? 

Renting a storage unit that is too small will result in a cramped space where you can’t easily access your items—on the other hand, renting a unit too large means paying for unused space. By finding the perfect size, you can optimise your storage experience and make the most out of your rental.

Using our Size Estimator

We have developed a user-friendly estimator tool to help you determine the ideal storage unit size you need. Our storage unit size estimator is a visual guide that will give you a clear idea of the space you need and help you make an informed decision.

Remember that the calculator is a guide, and the actual size you need may vary slightly based on the dimensions of your items.

Use the size estimator above to get an idea of what size unit you need. You can always upsize or downsize your unit, as and when your situation changes, with no commitment to a particular size, subject to availability.
