When you need extra space—whether you’re moving house, renovating, or simply decluttering—finding the right storage unit size can save time, money, and stress. Yet beginners often feel uncertain about where to start. Should you rent a small closet-like unit or an expansive garage-style space? How do you measure furniture or decide what to store? This guide walks you through the essential points: understanding common unit dimensions, comparing them to everyday household areas, and packing so you avoid wasted space. Along the way, you’ll discover how Britannia Lanes Storage offers expert help in choosing storage solutions that fit your needs.
Why Size Matters
Choosing an optimal unit size means you won’t pay for more room than you need, and you’ll also avoid the frustration of a cramped space. A unit that’s too large raises monthly costs for unused square footage, while an undersized option can leave you juggling boxes in a precarious pile. Striking the right balance affects:
- Budget
Overestimate and you waste money; underestimate and you might need a second unit. - Accessibility
A well-chosen size lets you label and stack items neatly, creating clear pathways. - Item Safety
Proper space reduces the risk of damage. Tight corners or overstuffed areas can harm fragile or valuable possessions. - Future Flexibility
Factoring in possible growth—like new furniture, extra boxes, or equipment—lets you avoid a rushed upgrade later.
Common Storage Unit Sizes and Everyday Comparisons
Rather than guessing square footage, visualise common unit sizes by comparing them to typical household spaces. Here are some popular ranges:
25–35 Square Feet (Cupboard-Size)
A unit this small is like a large hall cupboard. It holds several boxes, seasonal clothes, or compact appliances. It’s ideal for short-term needs, like storing items during a quick room refresh.
50 Square Feet (Walk-In Wardrobe)
Roughly the size of a walk-in closet, this unit can fit items from a small studio flat: a disassembled bed frame, a modest sofa, and around 15 boxes. It’s one of the most popular sizes for people looking to free up space at home.
75–80 Square Feet (Small Bedroom)
Comparable to a small single bedroom, these units can hold larger furniture—think a double bed, a few chairs, and an assortment of boxes. Perfect if you’re renovating one or two rooms and need space for furnishings.
100 Square Feet (Single Garage)
This size can store the contents of a one- or two-bedroom flat, including bulky appliances like fridges and washing machines. If you’re moving from a modest property, 100 square feet is usually enough.
150+ Square Feet (Small House Contents)
For up to three bedrooms’ worth of belongings, you’ll want around 150 square feet. This space can accommodate furniture, appliances, and multiple boxes without forcing you to stack items awkwardly.
Measuring Your Items
The key to selecting the right unit is knowing the approximate volume of the belongings you plan to store. Take a practical approach to measuring:
- Use a Tape Measure
Note the length, width, and height of bulky furniture. A sofa might be 200 cm wide, 90 cm deep, and 80 cm high. Having actual figures helps you picture how items will slot together. - Track Box Quantities
Estimate how many boxes you’ll have and their approximate sizes (small, medium, large). Write these figures down for easy reference. - Group by Category
Cluster similar items—kitchenware, bedroom linens, garage tools—so you can quickly see their collective volume. This also makes them easier to label and stack. - Account for Air Space
Stacking boxes to the ceiling might seem efficient, but if you need frequent access, you’ll end up moving items repeatedly. Aim for safe, stable piles with room to manoeuvre.

Packing Methods to Maximise Space
Even with the perfect unit size, poor packing can waste space and create disorganisation. Adopt these techniques:
Disassemble Furniture
Beds, tables, and shelving units usually shrink in size when taken apart. Keep bolts and screws in labelled bags taped to the main item so they’re easy to locate later.
Use Uniform Boxes
Mismatched box sizes produce awkward gaps. Investing in a set of uniform boxes allows for neat stacking and reduces wasted corners or overhangs.
Place Heavy Items at the Bottom
Prevent breakage and keep piles stable by placing heavier boxes on the floor. Lighter items can stack on top, reducing strain and minimising the risk of collapse.
Label Clearly
Write the contents on each box. If you need quick access to winter clothes or important documents, clear labelling saves time. Keep fragile items marked distinctly so they’re handled with care.
Leave a Centre Aisle
If you plan to retrieve items occasionally, create a narrow walkway. You won’t have to unload half the unit every time you need one box.

Need packing supplies? Not sure how to store delicate items? Staff members can advise on everything from the right boxes to climate-controlled options (if relevant) to keep valuables in top condition.
Working with professionals removes the guesswork and minimises the chance of renting a unit that’s too large or too small.
Balancing Space Requirements with Cost
We all want to save money, but the cheapest option isn’t always the best. A unit that’s cheaper per month might quickly become a hassle if it’s too cramped. Alternatively, a premium unit can be wasted space if you’re only storing a few boxes. Consider these pointers:
- List Everything
Make an inventory of every large piece of furniture, plus estimated box counts. This helps you compare actual volume against available sizes. - Factor in Long-Term Use
If you plan to store items for over a year, leaving wiggle room for future additions could be more economical than switching to a bigger unit later. - Declutter First
Don’t pay to store belongings you may never use again. Donate, sell, or recycle items you’re unlikely to need. This will reduce how much space you rent. - Seasonal Storage
If you have a lot of seasonal items (garden tools or holiday decorations), consider how often you’ll swap them out. A slightly larger unit can accommodate rotating gear without forcing you to rearrange everything each visit.
Label and Organise for Easy Access
Accessibility is a big reason people regret their storage decisions. Imagine needing your Christmas lights buried behind piles of boxes in June. A little organisation goes a long way:
- Categorise Boxes
Keep items from the same room or category together. Grouping them in adjacent stacks helps you locate them instantly. - Use Colour Coding
Applying a coloured sticker or marker for each room (kitchen in green, bedroom in blue) can simplify the retrieval process. Even a quick glance tells you which stack is which. - Create a Simple Inventory
Jot down box numbers with a brief description—Box 1: Bed Linen, Box 2: Kitchen Utensils—on a sheet of paper or a smartphone note. When you need something, check the list and go straight to the right spot. - Place Essentials Up Front
If there are certain items you’ll need sooner rather than later, set them near the unit entrance. Frequent rummaging deep inside your storage space can become a chore, so plan accordingly.
Planning for Future Growth
Many people start with a set of items in mind, forgetting their needs might evolve. You could inherit family antiques, expand a hobby, or purchase new furniture. Keeping some extra space can save you from the inconvenience of relocating everything to a new unit.
- Seasonal Rotation
Store winter clothes, skis, or holiday decorations, then switch them out when the seasons change. If you’ve crammed your unit to the brim, this becomes difficult. - Business and Hobbies
Perhaps you run a small online shop or have a creative pastime that generates extra materials. Some breathing room in your unit keeps these items neatly organised. - Family Changes
With children growing up or new family members moving in, you may need extra spots for furniture or keepsakes. A slightly larger unit is often easier than upgrading mid-contract.
Tips to Avoid Pitfalls with Your Storage Unit Size
Even with thorough research, mistakes can happen. Keep these pitfalls in mind:
- Not Visiting the Facility First
Photos online might be misleading about layout, security, or cleanliness. A quick on-site visit provides peace of mind. - Guessing Instead of Measuring
Estimations can be way off, especially for oddly shaped items. Take a tape measure and get real numbers. - Ignoring Humidity or Climate Factors
If you’re storing electronics, antiques, or papers, ask about temperature and moisture control. Certain items may need special conditions to avoid damage. - Skipping Insurance
Even with top-notch security, accidents can occur. Consider adding an insurance plan for valuable items to protect yourself financially.
