What Affects How Much Storage Space You Need?
Before choosing a unit, consider what you need to store and how much access you will need while your items are in storage.
The main things that affect storage space include:
- How many rooms you are storing
- The size and type of furniture
- How many boxes you have
- Whether furniture can be disassembled
- How well your items are packed
- Whether you need walkway space inside the unit
- How long your items will be stored
The better you pack, the less space you will need. Using strong boxes, stacking items carefully and taking furniture apart where possible can help you make better use of the unit.
If you are still unsure what items are suitable for storage, read our guide on what you can store in a storage unit.
Storage Unit Size Guide: Real-Life Examples
Here is a simple way to estimate your storage needs.
Small Storage Unit
A small storage unit is best for:
- Boxes and personal items
- Clothes and seasonal items
- Small furniture pieces
- Documents and household goods
- Decluttering a room or garage
- Student items during holidays
A small unit is ideal if you only need to store a few items, clear space at home or keep seasonal belongings out of the way.
Medium Storage Unit
A medium storage unit is best for:
- Beds, couches and appliances
- Boxes and household items
- Apartment contents
- Furniture from one or two rooms
- Items from a small move
- Renovation storage for one or two rooms
This is often the most practical option for people moving house, renovating or storing the contents of a 1–2 bedroom apartment.
If you are moving and need temporary storage between homes, read our guide to storage for moving house in Cape Town.
Large Storage Unit
A large storage unit is best for:
- Full household furniture
- Multiple rooms worth of items
- Large appliances
- Bulky furniture
- Long-term storage
- Full relocations
- Downsizing from a larger home
A larger unit is usually better if you are storing the contents of a full home or need space for large furniture items and many boxes.
If your main need is storing couches, beds, tables, wardrobes or other large household items, read our guide to furniture storage in Cape Town.
Storage Space for Common Situations
Moving House
Most moves require a medium to large storage unit, depending on the size of your home and how many items you need to store.
If you are between homes, storage gives you flexibility and reduces the pressure of moving everything in one day. It also gives you time to unpack at your own pace.
For more moving-specific advice, read our guide to storage for moving house in Cape Town.
Furniture Storage
If you are only storing furniture, the amount of space you need depends on how many pieces you have and whether the furniture can be taken apart.
As a simple guide:
- Small unit: a few key pieces of furniture
- Medium unit: lounge furniture and bedroom furniture
- Large unit: full household furniture
Before placing furniture into storage, make sure it is clean, dry and properly covered. For more detail, read our guide to furniture storage in Cape Town.
Decluttering
For clearing space at home, a small unit is usually enough. This is ideal for boxes, seasonal items, décor, clothing, documents and items you do not use every day.
Decluttering storage is useful when you want more space at home without throwing away belongings you may still need later.
Renovating Your Home
Storage keeps your furniture, appliances and personal belongings safe and out of the way during renovations.
Most people use a medium storage unit for renovation storage, especially when clearing furniture from a bedroom, lounge, kitchen or living area.
If you are renovating, read our guide to storage while renovating for tips on protecting your belongings during building work.
Short-Term vs Long-Term Storage Needs
The amount of space you need can also depend on how long your items will be stored.
If you only need storage for a short period, you may want easier access to your boxes and furniture. This means leaving some walkway space inside the unit can be useful.
For long-term storage, you may not need regular access, so items can often be packed more tightly and stacked more efficiently.
If you are unsure which option is best, read our guide to short-term vs long-term storage.
Tips to Maximise Your Storage Space
Make the most of your unit by packing and stacking properly.
Useful tips include:
- Disassemble large furniture
- Stack boxes efficiently
- Use uniform box sizes where possible
- Place heavier items at the bottom
- Keep fragile items protected
- Store items you may need near the front
- Use the full height of the unit
- Leave a small walkway if you need access
Smart packing can reduce the size and cost of your unit.
Avoid Choosing the Wrong Size
Choosing the wrong storage unit size can cause frustration and unnecessary cost.
If the Unit Is Too Small
You may run out of space, overcrowd your items or increase the risk of damage. Boxes may need to be stacked too tightly, and furniture can become harder to protect.
If the Unit Is Too Large
You may pay more than necessary for space you do not need. The goal is to find the right balance between enough room to store your belongings safely and not overpaying for unused space.

Choosing the right storage unit does not have to be difficult.
Our team can quickly recommend the best size based on:
