How to Choose the Right Storage Unit Size
Choosing the right storage unit size can save you both money and stress. Too small, and you’ll struggle to fit everything in. Too large, and you could end up paying for space you don’t actually need.
Whether you’re moving house, decluttering, renovating, or storing business stock, understanding how much space you need is the key to making storage simple and cost-effective.
The good news? Our online storage calculator makes it easy to estimate the right amount of space before you book.
Start by Thinking About What You’re Storing
Before choosing a unit, make a quick list of the items you plan to store. Ask yourself:
Are you storing mainly boxes?
Do you have large furniture items?
Will you need regular access to your belongings?
Is this short-term or long-term storage?
A few stacked boxes require far less space than sofas, wardrobes, appliances, or office equipment. Planning ahead helps you avoid choosing a unit that’s either too small or unnecessarily large.
Common Storage Unit Sizes Explained
Small Storage Units - between 25sq ft - 35sq ft
Ideal for:
Boxes
Seasonal decorations
Sports equipment
Student storage
Small office items
A small unit is perfect if you simply need extra space at home without storing bulky furniture.
Medium Storage Units - between 35sq ft - 75sq ft
Ideal for:
Contents of a one-bedroom flat
Furniture
Bikes
Business stock
Home office equipment
These are often the most popular option because they provide flexibility without excessive unused space.
Large - Extra Large Storage Units - between 75sq ft - 175sq ft
Ideal for:
Full house moves
Large furniture sets
Long-term family storage
Business inventory
Renovation projects
If you’re storing the contents of multiple rooms or need regular access to your items, a larger unit can make organisation much easier.

Pack Smart to Maximise Space
The way you pack your storage unit can make a huge difference to how much space you need.
To make the most of your unit:
Use sturdy, stackable boxes
Disassemble furniture where possible
Store heavier items at the bottom
Make use of vertical space
Keep frequently used items near the front
Efficient packing can often reduce the amount of storage space required.
Think About Accessibility
Some customers pack their unit once and don’t return for months. Others need regular access to stock, tools, seasonal items, or household belongings.
If you expect to visit your unit frequently, it’s worth leaving walkways or choosing slightly more space for easier access and organisation.
