Choosing the right amount of storage can make a big difference when you are moving, renovating, decluttering or simply trying to free up space. Get it right, and everything feels easier. Get it wrong, and you may either struggle to fit everything in or end up paying for more room than you actually need.
That is why so many people in Tunbridge Wells ask the same question before booking storage, what size self storage unit do I need?
The good news is that you do not need to get caught up in complicated measurements to make a sensible decision. In most cases, it comes down to knowing what you are storing, how often you may need access, and whether this is a short-term solution or something you expect to use for longer.
In this guide, we will walk through a practical way to judge your storage needs without overcomplicating it.

Why the Right Amount of Space Matters
Choosing a storage unit is not only about finding somewhere to put your things. It is also about avoiding unnecessary stress and making sure the space works properly once everything is inside. Too little room can cause problems straight away. Furniture may not fit as planned, boxes can become difficult to stack, and you may lose access to things you thought would be easy to reach. On a busy moving or renovation day, that can quickly become frustrating.
Too much room has its downside too. You may be paying for space that is not being used, which can feel wasteful, especially if storage is only needed for a temporary period. The best choice is usually the one that gives you enough room to store items safely and sensibly, without paying for more than you need.
A quick way to think about it
Before choosing storage, ask yourself:
- Do I only need room for boxes and smaller items?
- Am I storing bulky furniture as well?
- Will I need to get to things regularly?
- Am I likely to add more items later?
Those four questions often tell you more than measurements alone.
A Better Way to Judge Your Storage Needs
Rather than thinking about storage in abstract terms, it is usually easier to picture what is actually going in.
Start with the items that take up the most room
The biggest belongings tend to shape the space more than anything else. A few boxes are easy to imagine. A sofa, mattress, wardrobe or large desk is where the real calculation starts.
Begin by listing larger items such as:
- Beds and mattresses
- Sofas and armchairs
- Wardrobes and drawers
- Tables and chairs
- White goods
- Shelving
- Bicycles, tools or garden equipment
Once you have those in mind, add the smaller items like boxes, bags, files, decorations and household extras.
Then think in categories
Grouping your belongings can make the decision much clearer.
| What you are storing | What that usually means for space |
| Boxes and bags | Easier to stack, but can build up fast |
| Furniture | Bulkier, harder to organise neatly |
| Appliances | Heavy and awkward to move around |
| Business stock | Often tidy to store, but may need access |
| Fragile items | Need more careful placement |
This is often a better way to judge storage than counting every item one by one.
Do not just ask “will it fit?”
A common mistake is focusing only on whether everything can be squeezed in. In reality, you also need to think about whether the space will work once packed. For example:
- Will you need to access certain boxes?
- Do you want to keep business stock organised?
- Will tools or paperwork need to be reached later?
- Are you likely to keep adding items over time?
If so, a tightly packed space may not be as practical as it first seems.
Think about the kind of move or change involved
Someone storing the contents of a student flat for the summer will usually need far less room than a family moving out of a house during renovation work. The same goes for someone storing seasonal decorations compared with someone clearing several rooms before selling a property. The situation matters just as much as the item count.
Simple Ways to Make Better Use of the Space
Good packing makes a real difference, no matter how much storage you choose.
A few practical tips
- Use sturdy boxes that can be stacked safely
- Label boxes clearly on more than one side
- Dismantle furniture where possible
- Put heavier items at the bottom
- Use covers for mattresses and soft furnishings
- Keep anything important near the front
These small steps can make the unit easier to load, easier to organise and easier to use later.
One thing people often forget
Many people remember the main rooms in the house but forget the loft, garage, shed or spare room until the last minute. Those extra items can quickly affect how much space is really needed, so it is worth factoring them in from the start.
The Easiest Way to Get It Right
If you are trying to work out what size self storage unit you need, the simplest approach is to be realistic. Start with your biggest items, think about how many rooms’ worth of belongings are involved, and consider whether you will need regular access once everything is stored.
For people in Tunbridge Wells, that usually gives a far clearer answer than relying on guesswork alone. If you would like help choosing the most practical option, Store Anything can offer straightforward advice and help you find the right fit for your needs.
