How to choose the ideal size?

Choosing the right storage unit size is essential to optimize your investment. A box that's too small can make accessing your belongings difficult, while one that's too large represents unnecessary costs. In this guide, we help you find the perfect balance.

Measure your belongings

Make a list of items you want to store and estimate the total volume. Remember to consider height for stacking.

Think about access

If you need frequent access to your belongings, reserve space for corridors and organize by frequency of use.

Consider the future

If you expect to accumulate more items, consider a slightly larger size. You can always switch to a smaller box later.

Frequently Asked Questions

Questions about sizes?

We answer the most common questions about choosing storage unit sizes

How do I choose the right size for my storage unit?
To choose the ideal size, make a list of items you want to store. As a reference: 1-2m² for boxes and documents, 3-4m² for one bedroom, 5-8m² for a 1-2 bedroom apartment, 10-15m² for a 3-bedroom or small house. Use our space calculator for a more accurate estimate.
Can I change box size after renting?
Yes, you can switch to a larger or smaller box at any time, subject to availability. Just contact us and we'll handle the move at no additional transfer cost.
What is the height of the boxes?
Most of our boxes are between 2.5m and 3m high, allowing vertical stacking of boxes and furniture. This maximizes the available useful space.
What if I need more space than a single box?
You can rent multiple adjacent boxes to create a larger space. Contact us for customized solutions for business needs or larger volumes.
Is it better to rent one large box or two small ones?
Generally, a larger box is more economical per m². However, if you need to organize different types of goods separately (e.g., confidential documents vs. furniture), two boxes may be more practical.
How much fits in a 5m² box?
A 5m² box accommodates approximately the contents of a studio or 1-bedroom apartment: 2-seater sofa, double bed, wardrobe, desk, 10-15 medium boxes, and some small appliances.
