How Much Storage Space Do I Need?

First things first, let's assess what you plan to store.
Are you storing away seasonal items, furniture, business inventory, or perhaps even a vehicle? To find the perfect solution, assess your belongings and estimate how much space they will require.

Choosing the Right Size Unit

When it comes to selecting a storage unit, it's essential to understand that not all storage companies follow the same size standards. However, we've compiled a list of average sizes that are commonly available across the industry. 

But before we get to that, let’s understand what exactly is a square foot (sq ft), and how much can it hold. A square foot is a unit of area equal to a square that is one foot on each side.

To put it into perspective, one square foot can fit an average floor tile, a small cushion, or even a large toaster. Visualising the size of a square foot can help you gauge how much space you'll need for your belongings.

Here's a breakdown of common unit sizes and what they can typically accommodate:

1. Small Storage Units:

Perfect for storing items from small spaces such as boxes, small furniture items, seasonal decorations, or sports equipment. Think of it as your personal closet away from home. 


10 sq ft: Equivalent to a small closet or locker. 

25 sq ft: Comparable to a walk-in closet. Ideal for storing the contents of a small room, including boxes, small furniture items like chairs or bedside tables, or seasonal clothing.

2. Medium Storage Units:

Ideal for storing the contents of a one-bedroom apartment or a small office space. You can fit in large items including large furniture pieces, appliances, and several boxes with ease.


50 sq ft: Similar in size to a standard garden shed. Can accommodate the furnishings of a studio apartment, including a mattress, small sofa, dining set, and boxes.

75 sq ft: Equivalent to a large closet or utility room. Suitable for storing the contents of a small one-bedroom apartment, including furniture like a bed, dresser, and sofa, as well as multiple boxes.

3. Large Storage Units:

Need to store the contents of a large or multi-bedroom house or the inventory of a growing business? A large storage unit provides ample space for bulky furniture, appliances, and sizable equipment. 


100 sq ft: Comparable to a small bedroom. Ideal for storing the contents of a one-bedroom apartment, including furniture like a bed, sofa, dining set, and multiple boxes.

150 sq ft: Similar in size to a large bedroom or half of a standard garage. Can accommodate the furnishings of a two-bedroom apartment or small house, including furniture, appliances, and boxes.

200 sq ft: Equivalent to a large bedroom. Suitable for storing the contents of a two or three-bedroom house, including furniture, appliances, and multiple boxes.

400 sq ft: Comparable to a small warehouse space. Ideal for storing the contents of a large house or apartment, including furniture, appliances, vehicles, and numerous boxes.

By understanding the capacity of each storage unit size, you can choose the one that best fits your storage needs and ensures that your belongings are stored safely and efficiently.

Estimating Space Requirements

Still uncertain about which size to choose? Plenty of online calculators can help you estimate the space you'll need based on the items you plan to store.

Take advantage of these tools to ensure you're not overpaying for space you won't use or cramming your belongings into a unit that's too small.

 It's also worth noting that the height of storage units in the UK can vary, so it's essential to check the height of the unit to ensure you have enough stacking space. This will prevent any issues when it comes to fitting your items comfortably and maximising the use of the space.

Factors to Consider

Aside from the sheer volume of your items, there are other factors to consider when selecting a storage unit size. Accessibility, organisation, and potential future needs should all play a role in your decision-making process.

For instance, consider leaving space for aisles for easy access to your items, and think about how you'll organise the unit to make the most of the available space.

Additionally, if you anticipate needing access to your belongings frequently, opting for a slightly larger unit can save you from the hassle of rearranging everything every time you visit.

Getting the Most Out of Your Self-Storage Unit

Organising your self-storage unit effectively is key. With the right storing technique, you can make the most of every inch of space available. Utilise vertical space by stacking items vertically and placing heavier items on the bottom to prevent instability.

It's always wise to avoid stacking your belongings too high in your storage unit. After all, you wouldn't want to end up playing a real-life game of Jenga with heavy boxes and find yourself buried under a mountain of stuff. 

With a little creativity and planning, you can transform your storage unit into a well-organised and efficient space to store your belongings.
