Why We Overestimate Storage Space Needs

It is natural to struggle to visualise how belongings fit into a contained storage space, especially when looking at items scattered throughout your personal space.

The Visualisation Challenge

When looking at possessions spread across rooms, flats, or houses, it becomes difficult to picture them packed efficiently into a single unit. People imagine laying everything on the floor, but effective storage uses the full unit volume, especially the vertical height storage facilities provide.

Professional vs Personal Perspective

Storage professionals see the “packed” version of belongings, not the “spread out” version people may see at home. This expertise comes from helping customers match storage needs with suitable unit sizes and understanding exactly how much space different item combinations require when organised properly.

This experience gap explains why customers initially think they need larger units than they actually do. A storage unit size guide based on real customer experiences helps bridge this knowledge gap and prevents overspending on unnecessary space.

Common Storage Unit Sizes and What They Actually Hold

Understanding what different unit sizes accommodate helps make informed decisions based on real-world capacity instead of guesswork.

Small Units (25-35 sq ft) – The Spare Room Solution

Small storage units work like large garden sheds or spacious walk-in wardrobes, providing more capacity than people expect:

• Around 30-40 medium-sized boxes stacked efficiently using vertical space.
• A small sofa plus additional furniture like chairs or small tables.
• A double mattress and bed frame, when properly dismantled.
• Complete contents of a student flat or bedsit, including clothes, books, and electronics.
• Seasonal storage items like garden furniture, Christmas decorations, or sports equipment.
• Ideal solution for decluttering a single spare room with fewer costs.

Student storage customers may find these sizes ideal for term-time storage, accommodating everything from a university room without overwhelming space or cost.

Medium Units (50-75 sq ft) – The Most Popular Choice

Medium units are a popular size range for people managing house moves and major life transitions.

A 50 sq ft unit can comfortably hold the contents of a standard Transit-style van, while a 75 sq ft unit provides roughly half a single garage’s space. This range works well for storing furniture and boxes from one or two-bedroom flats or small houses, including sofas, beds, dining tables, and white goods.

Home storage customers should consider these sizes when moving between properties or during renovations. They will find that they provide ample space for temporary storage needs without paying for unused capacity.

Large Units (100-150 sq ft) – Family and Business Storage

Large storage units, roughly the size of a typical single-car garage, accommodate substantial storage requirements for families and businesses.

These units handle the contents of average three-bedroom family homes, including large furniture, multiple appliances, and many boxes. Business storage customers will benefit from these sizes for storing stock, archives, or equipment needing secure, accessible space.

The 100-150 sq ft range provides good value for customers with substantial storage needs. It offers generous capacity while offering reasonable monthly costs compared to commercial alternatives.

Professional Packing Techniques That Make Good Use of Space

The difference between needing a 50 sq ft unit versus a 75 sq ft unit can boil down to how you pack and organise belongings.

Using Vertical Space Well

A common mistake is using only floor space when storage units offer greater vertical capacity. Our units provide generous height, allowing you to stack sturdy, well-labelled boxes high to use the full volume you’re paying for.

Correct vertical stacking can increase effective storage capacity greatly compared to floor-only arrangements, making smaller units work for larger storage requirements.

Creating Accessible Organisation Systems

When packing your unit, leave a walkway down the middle to maintain easy access to boxes and items at the back without emptying the entire space. This approach is less frustrating and makes stored items more accessible when needed.

Drive-up storage units work well with this organisation method, allowing you to easily move items in and out while maintaining your internal layout.

Space-Saving Furniture Preparation

Dismantling everything creates space savings that can help reduce the required unit size. Take legs off tables, dismantle bed frames and cots, and remove shelves from bookcases before storing.

If sofas are sturdy enough to handle this positioning, they can be stored on their ends, saving floor space. These simple preparation steps can mean the difference between medium and large unit requirements.
