When it comes to self storage in the UK, one of the biggest questions is:
“What size storage unit do I actually need?”
At Ready Steady Store, we know it’s not always easy to picture how much space your belongings will take up. Whether you’re moving house, decluttering, starting a business, or just need a bit of extra room, choosing the right unit size can save you stress, time, and money.
In this guide, we will walk you through everything you need to know from storage unit sizes and costs to common scenarios – so you can feel confident you’re picking the right fit.
Why Choosing the Right Storage Unit Matters
Picking a unit isn’t just about where to put your stuff. It’s about peace of mind. The right storage space means your belongings are:
- Protected – safe from weather, damage, and theft
- Organised – so you can find things quickly when you need them
- Cost-effective – no wasted money on space you don’t use
At Ready Steady Store, we offer a wide range of unit sizes across our UK locations, with flexible terms and secure facilities. Whatever your situation, there’s a space to match.

Step 1: Work Out What You’re Storing
Before you start comparing unit sizes, take stock of your belongings.
Ask yourself:
- Am I storing a few boxes and small items, or larger furniture and appliances?
- Do I need space for an entire house move?
- Will I need to access things regularly, or will they stay stored away for months?
Pro tip: Make a quick inventory. Group items by size (boxes, furniture, appliances) so you can better picture how much room you’ll need.plan to store and group them by size and shape. This makes it easier to visualise how much space you’ll need.
Step 2: Understand Storage Unit Sizes
At Ready Steady Store, we make it simple. Here’s a quick guide to help you visualise or check out our handy size estimator:
- 9 sq ft locker – Great for a few boxes, sports kit, or seasonal decorations
- 25 sq ft unit – Perfect for student storage, or the contents of one small room
- 50 sq ft unit – Fits the belongings of a one-bedroom flat
- 75 sq ft unit – Good for a two-bedroom home, including furniture and appliances
- 100–150 sq ft units – Ideal for a three-bedroom house move
- 200+ sq ft units – For large house moves, businesses, or bulk stock storage
Still unsure? Think of 50 sq ft as about half a garage, and 150 sq ft as a typical single garage.hoose a slightly larger unit so you have space to move around and access your items easily.
Step 3: Match Storage Units to Real-Life Situations
Here’s how different people use storage – maybe one sounds like you:
- Moving house: Got a gap between moving out and moving in? Many families find a 100–150 sq ft unit is perfect for holding furniture and boxes safely until moving day
- Renovating: Redecorating your home? Protect your sofa, appliances, and valuables from dust or paint splatters. A 50–100 sq ft unit usually does the job
- Decluttering: Not ready to part with certain belongings but need space at home? A 9–25 sq ft locker is a handy option for seasonal clothes, sports gear, or sentimental items
- Students: Meet Sophie, a university student in Leeds. She didn’t want to cart everything home over summer, so she booked a 25 sq ft unit – just right for her bedding, books, and kitchen bits
- Businesses: Small businesses and online shops love using storage for stock, documents, and equipment. From 50 sq ft for boxes to 200+ sq ft for bulk inventory, there’s flexible space for every business
- Special equipment: Storing expensive kit? Choose a facility with 24-hour CCTV monitoring for maximum protection

Step 4: Look Beyond Size – Facility Features Matter
Not all storage is the same. At Ready Steady Store, we provide:
- Extended hour access – so you can get your things when you need them
- CCTV and secure entry – round-the-clock protection
- Flexibility – stay as little or as long as you like (minimum of 4 weeks stay)
- Free parking & trolleys – making move-in and move-out stress-free
When comparing storage providers, look at the whole picture – not just size and price.
Step 5: Pack & Organise Like a Pro
Maximise your storage space with a few smart tricks:
- Use uniform boxes for easy stacking
- Put heavy items at the bottom, lighter ones on top
- Leave a walkway so you can reach everything
- Label boxes clearly
- Add shelving if you need vertical space
Organised storage often means you can get away with a smaller (and cheaper) unit.
Common Mistakes to Avoid
- Going too small – leads to cramming, damage, and frustration
