Which storage unit size is right for you?
Finding the right storage unit doesn't have to be complicated.
Our BOXLY storage advisor & booking assistant analyses your details or even photos of your furniture and recommends the right storage unit including current availability and prices — fast, easy and free.
In most cases it takes less than two minutes.
Calculate storage unit size — find the right storage box
For example, you can:
- Describe your furniture
- Upload photos
- Ask questions
- Explain your moving situation
- Have the right storage box calculated for you
The BOXLY storage advisor & booking assistant then shows you directly:
- matching storage boxes
- current availability
- prices
- ongoing promotions
Why estimates are never perfect
No storage calculator in the world can determine space needs to the exact cubic metre.
Because every apartment is different.
For example, it makes a big difference:
- whether furniture can be dismantled,
- how many moving boxes you have,
- whether cellar or attic contents are also being stored,
- how well furniture can be stacked,
- or whether particularly large pieces of furniture are involved.
That's why our BOXLY storage advisor & booking assistant deliberately provides a realistic guide, not apparent precision.
The BOXLY solution
You don't have to calculate your space needs perfectly.
A good estimate is enough.
If it turns out during move-in that you need more or less space, we almost always find a suitable solution immediately.
Our goal isn't for you to pick the perfect storage box.
Our goal is for your move to go as smoothly as possible.
