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 4-bed house?
Consider 150 sq ft as a starting point for a four-bedroom house, with 200 sq ft or more possible for a fuller inventory. The smaller allowance assumes furniture can be arranged efficiently, beds dismantle and boxes stack safely. Several living areas, large wardrobes, garden equipment or a packed garage can make a substantial difference.
Build the inventory around what you are moving rather than the size of the house. An empty spare room adds little, while a workshop or home business may need its own allowance. Check the longest and tallest items, and keep a note of anything that must remain upright or cannot have weight placed on top.
The calculator starts with the four-bedroom preset and compares it with any rooms or items you add. It uses the larger estimate and adds an aisle allowance when requested. Above 200 sq ft it flags the need to speak to a provider about a larger unit or multiple units. Ask for written quotes covering the same stay, including protection and any one-off charges.
We do not currently have a sourced price for 150 sq ft; ask a provider for a written quote. These are dated examples, not a UK average. Prices checked November 2026; extras and availability must be confirmed.

Picture the possibilities
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.

Good questions.
Straight answers.
What if my four-bedroom house needs more than 200 sq ft?
The calculator flags estimates above 200 sq ft rather than treating 200 as sufficient. Ask the provider about a larger unit or multiple units and check the total cost and access arrangements.
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.
