A useful storage unit size guide should give you a starting range, then help you adjust it for the way your belongings will actually be packed and accessed. Newbury Self Store publishes household and van-based size guidance, but the right choice still depends on furniture, box count, awkward items and how long you expect to store them.
For a house move, Newbury Self Store’s personal storage size guide gives these indoor ranges: a 1 bed flat usually points to 50-65 sq.ft, a 2 bed flat to 75-90 sq.ft, a 2 bed house to 75-100 sq.ft, a 3 bed house to 100-150 sq.ft and a 4 bed house to 130-200 sq.ft. Treat these as planning bands, not a substitute for checking your actual inventory.
Start With The Quick Size Answer
If you are comparing storage for a whole home, begin with the property-size bands above. If you are working from a van load instead, the published guide gives a Transit van as 35-50 sq.ft, a Luton van as 50-80 sq.ft and a 7.5 tonne van as 120-170 sq.ft.
Those ranges are especially helpful when arranging personal storage for house moves because the pressure often arrives before every box is packed. A first estimate lets you ask sensible questions early, then refine the choice once the rooms, loft, garage and garden items have been counted.
The range matters because two homes with the same number of bedrooms can store very differently. A lightly furnished 2 bed flat may sit near the lower end of its band, while a flat with bookcases, bikes, office furniture and full kitchen contents may need the upper end.
Build The Inventory Around Rooms
Work room by room rather than trying to guess the whole load in one number. Write down the main furniture first, then add box counts and awkward items. Beds, mattresses, sofas, wardrobes, tables, desks, bicycles, mirrors, lamps, tools and garden equipment all change the space needed.
Do not forget the hidden rooms. Lofts, garages, sheds, airing cupboards and under-stairs spaces often hold the items that push a move into a larger unit. A storage estimate based only on visible furniture will usually be too tight.
For each room, mark what can be dismantled. A dining table with legs removed takes a different footprint from a table left assembled. Bed frames, desks, shelving and garden furniture may also store more efficiently when parts are removed, labelled and kept together.
Before you ask for a final recommendation, make the inventory specific enough to be checked:
- Count boxes separately from furniture.
- Mark anything fragile, heavy, long, tall or awkwardly shaped.
- Note which items must stay accessible after move-in.
- Add loft, shed, garage and cupboard contents before choosing the band.
If the inventory is still changing, use the practical steps in preparing belongings before personal storage to turn loose rooms into labelled, countable groups.
Use The Van Guide When The Load Is Already Packed
Sometimes the easiest measure is not the house, but the vehicle. If everything is already boxed and you know the load will fit into a particular van, the van ranges can give a practical cross-check against the home-size guide.
A Transit van range of 35-50 sq.ft suggests a smaller load of boxes or selected furniture. A Luton van range of 50-80 sq.ft may suit a more substantial flat move or a room-clearance project. A 7.5 tonne van range of 120-170 sq.ft points towards a much larger household load.
Use the larger of the two estimates if the home-size guide and van guide disagree. The gap is usually caused by bulky shapes, poor stacking, loose bags or items that cannot safely sit under heavier belongings.
The van guide is also useful when a move is happening in stages. If one Luton load is only the first half of a flat move, do not size the unit around that first journey. Add the later furniture, final kitchen boxes, plants you decide not to keep at home, and the loose items that often appear once cupboards are emptied.
Add A Buffer For Access
The smallest unit that can physically hold the contents is not always the right unit. If you will not need anything until move-out day, a tighter layout may work. If you expect to visit, remove documents, collect seasonal items or add boxes later, leave working space.
A narrow access route can save a lot of frustration. Put frequently needed items near the front, keep labels facing out and avoid creating a wall of unmarked boxes. Heavy, sturdy items belong low down, with lighter boxes above.
Build in extra room for protective covers, corners, handles and curved furniture. Real items do not pack like perfect rectangles. A little space around awkward furniture can prevent pressure marks, torn covers and repeated unloading during visits.
For long-term extra storage, the buffer should be larger than for a simple removals stopover. The personal storage information describes homes being built with less storage space, which means some customers use storage for items they cannot fit at home. In that situation, occasional retrieval is part of the plan.
Match The Band To The Life Event
For a straight house move, think about the day everything comes out. If removals will empty the unit in one trip, the layout can be denser. If completion dates may move or belongings will leave in stages, choose a size that keeps the unit usable.
For renovation or redecoration, access usually matters more. You may need tools, paperwork, spare clothing, kitchen boxes or children’s items while the work continues. A unit packed only for maximum density can become a problem halfway through the project.
For downsizing, allow time to sort. The personal storage information describes retirement downsizing as a situation where people may want to keep items but lack space, or need time and space to decide. That makes a clear inventory and a sensible review date as important as the initial size.
Check The Practical Service Details
Once the estimate is close, compare it with the practical terms. The FAQ says the minimum stay is one calendar month and that two weeks’ notice is required when the unit is no longer needed. It also says payment is collected in advance of the month starting.
Contents insurance is mandatory according to the FAQ. Customers need proof that goods are covered while in storage, or can use the benefit of Newbury Self Store’s insurance at the stated risk administration charge. A padlock is also needed, and padlocks are sold in branch if required.
These details can affect the final choice. A larger unit for one month may be more useful than a smaller one that creates extra trips, delayed move-out and hard-to-reach items.
Security and handling details matter too. The FAQ says each customer has a private lockable storage room, with the customer holding the key, and that trolleys and safety steps are provided for moving items in and out. Those details help you judge whether the estimated size will be workable on the day.
The storage FAQs are also the place to check booking, deposit, identification, payment, padlock and insurance details before the estimate becomes a booking.
Ask For A Measured Fit Before Booking
At the decision stage, use the published bands with the actual inventory. Newbury Self Store’s personal storage information says it offers a variety of unit sizes in a modern, purpose-built facility, with all storage units inside a modern, dry, secure warehouse.
The same personal storage information says staff can help choose a long-term, cost-effective option, and the FAQ recommends discussing storage needs with the team. That is useful if your list sits between two size bands or includes awkward items.
Call with the property size, van type if known, approximate box count, large furniture list and access needs. That gives the team something concrete to work from instead of a vague description such as “a few rooms”.
Make The Final Choice
Choose the lower end of a band only when the load is well packed, furniture is dismantled, items are stackable and you do not expect frequent access. Choose the upper end when there are bikes, garden tools, office furniture, fragile items, loose shapes or a longer stay.
Choose more working room if storage is part of a renovation, downsizing decision or staged move. Choose a tighter layout only when the contents will arrive together, stay untouched and leave together.
A good storage decision should make moving day calmer. Use the size bands, van guide, inventory and access needs as a decision ladder, then contact us to check the fit before you commit.
