How to choose the right Storage unit size

Thinking of storing your things in self storage but have no idea what storage unit size to pick? Choosing the right unit size depends on what you need to store. If you are a student, you may only need a compact unit just for books and seasonal items, while if you are a business, you might need a larger space for stock and equipment. Selecting a unit that’s too small could leave you short on space, while one that’s too large means paying for unused room.  

This guide will help you find the ideal size based on your specific storage needs so you can make the best choice for you. 

How self storage unit sizes work

Self storage unit sizes are designed to cater to a variety of needs, from personal to business storage. The size you choose will depend on the volume of items you need to store, their dimensions and how you plan to organise them.  

How self storage unit size works is that each unit is measured in square metres (m²). Think about both the floor space and the height of the unit you may need before committing to a unit size.  

Most self storage facilities offer units ranging from small lockers for personal items to large warehouse-style units for storing business stock or the contents of a large home.  

How to choose the right storage unit size 

Consider your inventory 

List everything you plan to store and measure larger items to determine how much storage space you need. If you're storing bulky furniture, appliances, or business stock, you may require a larger unit. 

Think about future storage needs 

If you anticipate adding more stored items, opting for a slightly larger unit now can save you from having to upgrade later. This is especially important for businesses managing storage solutions or expanding stock levels. 

Maximise storage space 

Using shelving units and stacking boxes efficiently can help you optimise vertical space, allowing you to store more in a small storage unit. Proper organisation ensures you make the most of your storage space while keeping items accessible. 

Storage unit size guide

If you're storing a few boxes, documents or seasonal items, a small unit may be perfect. For bigger furniture items or appliances, a medium unit offers more space. If you're moving house, storing business stock or need long-term storage for large items, a large unit is your best option.
