As a general guide, a studio or one-bedroom apartment might require a 4m² to 7m² unit, while a two-bedroom apartment may need around 10m². For larger homes, such as a three-bedroom house, a 15m² unit or more may be appropriate.

Factors to consider when choosing storage unit sizes
There are four main factors to consider when choosing a storage unit size.
These are:
Height: Make use of vertical space by stacking items like boxes or shelves. Most units are at least 2.4-metres high, so use this to your advantage.
Access: Will you need to access items regularly? Choose a layout with easy front access or wider doors for bulky items.
Speciality items: Large furniture, white goods and business inventory need more floor space. Consider disassembling furniture to save space.
Future needs: Leave a little extra room if you expect to add more items later. It’s often easier than upgrading later.
Consider these four variables when deciding on the dimensions of your storage unit. If you get stuck, get in touch with our helpful team to provide further guidance.
