17 Oct Choosing the Right Self Storage Unit for Your Needs
Choosing the Right Self Storage Unit sounds simple until you’re actually doing it. Most people either rent something too small and regret it immediately, or pay for way more space than they need for months on end.
Let me walk you through how to actually figure out what you need, avoid the usual mistakes, and pick a unit that makes sense for your situation.
Common Self Storage Mistakes to Avoid
Before we get into how to choose right, let’s talk about what goes wrong.
Underestimating space is the big one. People look at their stuff at home and think “that’ll fit in a small unit, no problem.” Then they get there and can’t even close the door. Furniture takes up more room than you think, especially when you’re stacking things in a storage facility.
Then there’s the access issue. You pack everything in perfectly, then need something from the back two weeks later. If you’ve crammed it all in with no walkways, you’re shifting half your belongings every visit.
Here’s another classic: not thinking about the future. You rent a unit for three months of house renovations, pack it perfectly, then the project runs over and suddenly you need to store more stuff. Now you’re juggling two units or trying to reorganise everything. Renovations always take longer than planned so factor that in from the start.
And going for the cheapest storage option without asking questions? A cheap unit with no security and limited access hours might cost you more in the long run through theft, damage, or sheer inconvenience.

How to Calculate Your Storage Space Requirements
Here’s the practical way to do this.
Start by listing everything you’re storing. You can’t estimate space without knowing what you’re putting in there. Furniture, boxes, equipment, get it all on paper.
Measure your big items or at least know roughly how big they are. That sofa might look reasonable in your living room, but it takes up proper space when you’re trying to stack things around it. Same goes for wardrobes, beds or appliances, these are your space-eaters.
Think about how you’ll pack it too. Can you dismantle things? Table legs come off, bed frames come apart. Flat furniture takes up way less space than fully assembled pieces. Wardrobes without the rail and shelves suddenly become much easier to work with.
Self Storage Unit Size Guide
Here’s a practical comparison table to help you work out what you actually need:
| Unit Size | Comparable To | What Fits | Good For |
| 25 sq ft | Small cupboard | 5-10 boxes, few small items | Seasonal decorations, student storage, sports equipment |
| 50 sq ft | Walk-in wardrobe | 10-15 boxes, chest of drawers, small items | University dorm contents, archive boxes, small bedroom |
| 75 sq ft | Small bedroom | Furniture from 1-bed flat, 15-20 boxes | House move, decluttering, studio flat contents |
| 100 sq ft | Large bedroom | 2-bed flat contents, appliances, 25+ boxes | House renovations, downsizing, extended travel |
| 150 sq ft | Single garage | 3-bed house furniture, garden equipment, bikes | Full house move, business stock, long-term storage |
| 200+ sq ft | Double garage | Entire house contents, vehicles, office furniture | Commercial storage, vehicle storage, house clearance |
Add 25% more than you think. This is the key bit. Whatever size you calculate, bump it up by a quarter. This gives you room to move around, space to organise, and buffer for those extra items you forgot about.
Types of Self Storage Units Explained
Standard units are basic boxes. Four walls, a door, maybe a light. Fine for furniture, boxes, tools and anything that doesn’t mind temperature changes.
Climate-controlled units keep temperature and humidity steady. You need these for:
- Wooden furniture that can warp
- Electronics
- Important documents
- Photographs
- Musical instruments
- Antiques or collectibles
- Anything leather
Costs more but worth it if your stuff matters. Doesn’t mean it’s heated like your house, just means no extreme temperature swings or dampness.
Drive-up units are ground floor with vehicle access right to the door. Makes loading and unloading way easier.
Good for:
- Heavy items
- Large furniture
- Frequent access
- Business stock
Indoor units are inside a building with corridor access. Better security, usually climate-controlled, but you’ll be carrying things down hallways. Fine for boxes and smaller items, annoying for furniture.
Vehicle storage is for caravans, boats, cars, motorbikes. Usually outdoor parking or covered spaces. Check if they require insurance and what security measures they have.
Understand Your Future Storage Needs
This is where people get unstuck. Here’s how to think ahead.
Be honest about how long you’ll actually need storage. House move? Probably 1-3 months. Renovations? Think 3-6 months because they always run over. Downsizing while figuring out your next move? Could be 6-12 months. Long-term storage of stuff you can’t let go of yet? Just admit it now rather than telling yourself it’s temporary.
Consider what else might need storing. Renovations have a habit of uncovering more problems. House moves get complicated. Life happens. If there’s any chance you’ll need more space, factor that in now. Upgrading units mid-contract is possible but often means moving everything twice.
How often will you need to get in there? Need access weekly? Daily? Once a month? This affects what type of unit you need and how you pack it. Frequent access means you need clear paths and proper organisation. Infrequent means you can pack it tighter and save some money on size.
Plan for seasonal swaps if that’s relevant. Storing Christmas decorations in summer? You’ll want them near the front come November. Same with sports equipment, camping gear, or seasonal clothing. Think about what you’ll need when, and pack accordingly.
Step-by-Step Guide to Choosing Self Storage
Right, let’s put this together into an actual process.
Step 1: Inventory. Make that list. Be thorough.
Step 2: Estimate size honestly. Use the room comparisons above. Remember: add 25%.
Step 3: Consider your items’ requirements. Does anything need climate control? Anything heavy requiring ground-floor access? Anything valuable needing extra security?
Step 4: Think about access. How often? What times? Some facilities have 24/7 access, others have limited hours. Match this to your actual needs.
Step 5: Work out your timeline. Be realistic. Add buffer time.
Step 6: Set your budget. Know what you can afford monthly. Remember to factor in insurance, which many facilities require.
Step 7: Visit facilities. Photos on websites look nice but don’t show you the reality. Go see the actual units, check security, meet staff, look at cleanliness.

Packing Smart Makes the Size Right
Even with the right size unit, you can waste space through bad packing.
- Dismantle what you can. Table legs off, bed frames apart. Flat furniture takes up way less space.
- Use wardrobe boxes for clothes. Keeps them clean and makes them stackable.
- Fill gaps. Soft items (bedding, cushions, clothing) can fill weird spaces around furniture.
- Stack heavy stuff on the bottom. Obvious but worth saying.
- Leave a path. Even just a narrow walkway means you can actually access things without a full reorganisation.
- Label everything clearly. You’ll forget what’s in boxes. Label at least two sides so you can see labels from different angles.
