What Size Storage Unit Do I Need? A Guide Based on Your Furniture and Apartment Size
Do you need to store a few pieces of furniture, the contents of a student room, or everything from your apartment? Choosing a storage unit is not just about floor space. It also depends on whether you can dismantle furniture, stack boxes and make use of the unit’s height. With a little planning, your belongings may fit into a smaller unit than you expect.
The guide below will help you estimate how much space you need. Treat it as a starting point: two apartments with the same layout can contain very different amounts of furniture and belongings.
Quick guide: which storage unit size should you choose?
| What you need to store | Approximate space needed | Suggested Super Storage sizes |
|---|---|---|
| A few pieces of furniture, boxes or the contents of a student room | 2–3 m² | XXS (2 m²), XS (2.86 m²) or XS Extra (3.07 m²) |
| A sofa, a bed and several boxes | 4–6 m² | S (4.14 m²) or M (5.72 m²) |
| The contents of a Czech 1+kk apartment, including appliances | 5–8 m² | M (5.72 m²), M Extra (6.15 m²) or L (7.72 m²) |
| The contents of a Czech 2+kk apartment | 6–9 m² | M Extra (6.15 m²), L (7.72 m²) or XL (9.25 m²) |
| The contents of a Czech 3+kk apartment | 9–12 m² | XL (9.25 m²), XL Extra (9.72 m²) or XXL (11.72 m²) |
| The contents of a Czech 4+kk apartment | Approximately 12 m² or more | XXL (11.72 m²), XXL Extra (12.34 m²), or two units |
These recommendations are estimates. The right size depends on the dimensions of your furniture, the number of boxes, how safely you can stack your belongings and whether you need regular access to them. Availability of individual unit sizes may vary by location.
Not familiar with Czech apartment labels? A 1+kk is a studio-style apartment with one main room and a kitchenette. In a 2+kk, 3+kk or 4+kk, the first number indicates the number of main rooms; “kk” means the kitchen is part of one of those rooms rather than a separate room.
A few pieces of furniture or a student room
Are you moving out of student accommodation, going away for a while or making space at home? If you mainly need to store boxes, suitcases, a chair, a small desk or dismantled furniture, start by looking at XXS (2 m²), XS (2.86 m²) or XS Extra (3.07 m²).
You can stack boxes and use the space inside empty shelves or cabinets for smaller items. Before choosing a unit, measure your longest item, such as a mattress or desktop, to make sure it will fit.
A sofa, a bed and several boxes
For a sofa, mattress, dismantled bed frame and several boxes, consider an S (4.14 m²) or M (5.72 m²) unit. The best choice depends mainly on the size of the sofa and whether the bed can be taken apart.
You can also make use of the space above your furniture. Lightweight boxes may be placed on a suitably protected sofa if they are stable and will not press into the upholstery. Keep heavy boxes and appliances on the floor.
The contents of a 1+kk apartment
Need to store a bed, sofa, table, cabinets, boxes and perhaps a fridge or washing machine? For a 1+kk apartment, start by comparing M (5.72 m²), M Extra (6.15 m²) and L (7.72 m²).
A smaller unit may be enough if your apartment is lightly furnished, you can dismantle larger items and you can stack boxes safely. A larger unit is useful if you have bulky appliances or want easier access to your belongings during the rental period.
The contents of a 2+kk apartment
For a 2+kk apartment, consider M Extra (6.15 m²), L (7.72 m²) or XL (9.25 m²). The apartment layout is only part of the picture: a minimally furnished home needs less storage space than one with a large sofa, dining table, wardrobes and appliances.
Dismantling a bed or table, using the space inside cabinets and stacking boxes can help you save floor space.
The contents of a 3+kk apartment
For a 3+kk apartment, start by comparing XL (9.25 m²), XL Extra (9.72 m²) and XXL (11.72 m²). First, list the large pieces of furniture and appliances that will need floor space. Then account for boxes and smaller items that can be stored above them.
If you will need to retrieve belongings regularly, leave room for access. Filling a unit right up to the door uses the space efficiently, but makes it harder to reach items at the back.
The contents of a 4+kk apartment
If you are storing the contents of a 4+kk apartment, look at XXL (11.72 m²) or XXL Extra (12.34 m²). Whether one unit is enough depends on how much furniture, how many appliances and how many boxes you have. For a fully furnished apartment, two units may be the more practical option.
Make a list of your larger items and their dimensions. Remember to include anything stored in a cellar, utility room or on a balcony—these belongings are easy to overlook when estimating space.
How can you fit more into your storage unit?
- Dismantle furniture where possible. Bed frames, tables and shelving usually take up less space when taken apart.
- Use the unit’s height. Stack sturdy boxes safely, with heavier ones at the bottom and lighter ones on top.
- Use space inside furniture. Cabinets and drawers can hold smaller belongings.
- Protect upholstered furniture. Only place lightweight items on a covered sofa, and avoid anything that could leave dents.
- Plan for access. Put the belongings you may need first closer to the door.
Not sure which size to choose? Start with a list
Before renting a unit, list your larger pieces of furniture, appliances and approximate number of boxes. Measure your sofa, mattresses, wardrobes and anything else that cannot be dismantled. Then decide whether your belongings will simply stay in storage or whether you will need to access them regularly.
With that list, it will be easier to choose a Super Storage unit that fits your belongings without paying for more space than you need.
