25 sq ft
A few stacks of boxes, a bicycle and a small piece of furniture. People often compare it with a large cupboard or a garden shed, but ceiling height and how tightly you pack change what fits.
Plan your storage
What size storage unit do I need for a 3-bed house?
A 100 sq ft unit is a starting estimate for a three-bedroom house. It may hold the main furniture and packed boxes when beds dismantle, mattresses can be stored safely on their sides and space above sturdy furniture is usable. A house with several large sofas, appliances or extensive garage contents may need a larger unit.
The number of bedrooms is only a shortcut. A home office filled with equipment can take more space than a lightly furnished spare bedroom. Count the rooms whose contents are going into storage, then check particularly bulky items in the inventory. Avoid relying on unsafe stacking to make the floor allowance work.
The three-bedroom preset is selected below. Switching to room-by-room mode does not erase it: the larger home, room or item estimate remains the starting point. Add the access allowance if you will need to walk between belongings. Before committing, give the provider your inventory and confirm the unit’s shape, clear height, loading arrangements and any restrictions on what you can store.
For 100 sq ft, the linked local tariffs give a range of £195.00–£197.91 per month including VAT. These are dated examples, not a UK average. Prices checked November 2026; extras and availability must be confirmed.

A size for every
sort of move.
Compare all seven starting sizes. Actual room shapes, ceiling heights and door openings vary between stores.
35 sq ft
The contents of a studio, or a room of boxes plus a sofa or a bed, if the rest of the flat is travelling with you or being sold.
50 sq ft
A one-bedroom flat packed with a bit of care, or a double bedroom plus boxes, a mattress and a wardrobe.
75 sq ft
A two-bedroom home if you are not storing every appliance, or a one-bedroom flat where you want an aisle so you can reach things.
100 sq ft
A three-bedroom house packed reasonably, including the larger furniture, as long as sofas and mattresses are not all stored flat on the floor.
150 sq ft
A larger family home, or a three-bedroom house where you want to walk between rows rather than unpack the door every time.
200 sq ft
A four- or five-bedroom house, house-clearance volume, or stock that needs floor space. Above this, ask a store about more than one unit.

A little more clarity
Good questions.
Straight answers.
Is 100 sq ft enough for every three-bedroom house?
No. It is a planning starting point. Large furniture, appliances, loft contents and a garage can increase the requirement. Measure bulky pieces and ask a provider to check the inventory.
Are the calculator prices a quote for my local store?
No. They use dated monthly tariffs from Rugeley Self Storage and Green Oak Self Storage. Location, availability, extras and contract terms affect your quote. Check the linked sources and ask for a written total.
