What size storage unit
do I actually need?

Start with a list, not a guess

The most common sizing mistake is to guess from the number of rooms in your house. Two people moving out of identical three-bedroom homes can need very different space: one has a loft full of boxes and a piano, the other has already sold half the furniture.

So start with a list. Walk round with a notepad or your phone and write down every large item: beds, sofas, wardrobes, tables, white goods, bikes, garden furniture. Then estimate your boxes. A standard medium moving box is roughly 45 cm on each side, and a typical room of everyday things tends to fill somewhere between ten and twenty of them once you are honest about cupboards and under-bed storage.

Big, awkward items decide the floor area. Boxes decide how high you need to stack. Keep the two separate in your head and sizing gets much easier.

Square feet to square metres

We quote floor area in square feet. One square foot is about 0.093 square metres, so to convert, multiply by 0.093. To go the other way, one square metre is about 10.76 square feet.

We only quote areas, not exact dimensions, so if a particular long item matters (a dining table, a sofa, a ladder), ask us on WhatsApp before you book and we will check it for you.

Pods and rooms: a few boxes up to a small flat

Our first-floor storage pods and rooms open in spring 2027 and are reached by stairs, so they suit things you can carry. These are guide prices, to be confirmed.

• 15 sq ft pod, from £10 a week (guide price). Roughly the space of a large wardrobe footprint. Think a dozen or so boxes, a suitcase or two, a folded bike or seasonal bits.
• 25 sq ft pod, from £14 a week (guide price). A student room's worth of belongings, or the contents of a cluttered spare-room cupboard.
• 35 sq ft pod, from £17 a week (guide price). Boxes plus a few small pieces such as a desk chair, bedside tables or a flat-packed bookcase.
• 50, 75 and 100 sq ft rooms, £22, £28 and £34 a week (guide prices). From the contents of one furnished bedroom up to a small one-bedroom flat, as long as nothing is too heavy to take upstairs.

Ground-floor units: rooms, vans and businesses

Our ground-floor units are windowless, with lighting and power already connected. Here is a rough idea of what each can take when packed sensibly with an aisle.

150 sq ft roller-shutter unit, £65 a week

Often enough for the contents of a two-bedroom home with a typical amount of furniture, or a one-bedroom flat with room to spare. The roller shutter makes it easy to back up and unload bulky items such as sofas and white goods.

160 sq ft security-door unit, £69 a week

Slightly more floor space, but access is through a personnel door rather than a shutter. That suits boxes, archives, stock and furniture that goes through a normal doorway. Very wide items are easier through a shutter.

180 sq ft roller-shutter unit, £78 a week

A comfortable fit for many three-bedroom households, or a two-bedroom home where you want space to walk in and find things. Also popular with traders storing tools and materials.

300 sq ft two-storey unit, £130 a week

A roller-shutter ground floor plus an upstairs office or storage area with a window, reached by an internal staircase. It suits larger households or anyone who wants storage below and a desk above.

These are rules of thumb, not promises. How high you stack and how much you have already got rid of matter more than the number of bedrooms.

What the space costs per square foot

Rent is based on floor area, so the ground-floor units work out at very similar rates: £65 a week for 150 sq ft is about £282 a month, or about £22.53 per sq ft per year. The 160 sq ft unit is about £299 a month, the 180 sq ft unit about £338 a month, and the 300 sq ft unit about £563 a month.

Pods cost more per square foot because they are small, but far less in total. A 25 sq ft pod at a guide price of £14 a week is about £61 a month. If all you need is room for twenty boxes, paying for a whole unit makes no sense.

Our storage prices explained page sets this out in full, and compare units side by side if you are torn between two.

Sizing for stock, tools and business use

Business storage is sized differently from household storage. Stock moves in and out, so you need a clear route to every shelf, and shelving itself takes floor space. A good rule is to plan the shelving layout first, then see how much floor is left for pallets, bulky items or a packing table.

Online sellers often find a 150 or 160 sq ft unit gives room for shelving along two walls and a packing area by the door. Trades who keep a van-load of materials and tools tend to prefer a roller-shutter unit so they can reverse up and load directly. If you need a desk as well, the two-storey unit's upstairs area, which has a window, keeps paperwork away from the dust below.

All business use needs our prior approval, so tell us what you plan to do when you enquire. Our ideas for online sellers and ideas for trades storage pages show how other businesses use similar space.

When you are between two sizes

1. Count the bulky itemsIf you have several large pieces of furniture, go for the bigger floor area. You cannot stack a sofa on a wardrobe.
2. Think about accessIf you will need things back regularly, allow room for a walkway. That can cost a fifth of the floor space.
3. Remember you can swapYou can move to a bigger or smaller unit at any time, subject to availability. Starting a little small is less risky than it sounds.
4. Consider joining unitsSome units have interconnecting doors, so you can rent two or three side by side, and get both shutter and personnel-door access.

Still unsure? Send a list or a few photos and message us on WhatsApp. We would rather help you pick the right size than have you pay for space you do not use.
