When it comes to freeing up space at home, storing business inventory, or making sure belongings don’t get tossed around during a moving process, the solution that comes most readily to mind is renting a storage unit. However, with so many different sizes, it is hard to decide. Going for a unit that’s too small would result in cramming and an expectation of some damage to your belongings, while a storage unit much larger than what is necessary just means that you’re paying for space you do not need.
How do you determine the size of the storage unit you need? The answer depends on what will be stored, how frequently access will be required, and whether extra space allowance is necessary for organisational purposes. This storage unit size guide helps determine whether business or personal storage is needed.
Factors That Affect Storage Needs
What you keep is an important determining factor in selecting the size of a storage unit. The following variables will influence your space requirement:
1. The Type of Items You’re Storing
Are you storing furniture, boxes, appliances, or business inventory? Bulky furniture and large appliances require more space, while smaller household items can fit into compact units.
2. Short-Term vs Long-Term Storage
If you only need storage for a short period, you can stack items more efficiently. However, you’ll need space for long-term storage so you can access items quickly without moving everything around.
3. Need for Access and Organisation
Do you need to access your items frequently? If so, leave extra room for aisles so you can walk in and retrieve things easily.
4. Storage for Personal vs Business Use
A storage unit for personal items may require less space than one utilised for business purposes, including large amounts of inventory, documents, or equipment.
Small vs. Large Storage Units: Which One Is Right for You?
Storage units come in different sizes: small lockers or big garage-type. So here is a quick breakdown for Small vs large storage units that can help more in making a decision:
Small Storage Units (1.5m x 1.5m x 2.9m (H) to 3.0m x 3.0m x 2.9m (H))
These units are ideal for:
- Seasonal items, decorations, and small furniture
- Temporary storage for students in between semesters
- Extra closet space for folks living in an apartment or small home
A 1.5m x 1.5m unit resembles a small closet, and a 3.0m x 3.0m would resemble a mildly spacious, small walk-in bedroom closet.

Medium Storage Units (4.0M X 3.0M X 2.9M (H) to 5.0m x 3.0m x 2.9m (H) )
Medium-sized units are best for:
- Storing furniture from one or two-bedroom apartments
- Temporary storage during remodels
- Business inventory, documents, and office supplies
A 4.0m x 3.0m storage unit can hold about half the contents of a standard garage, which holds what a one-bedroom apartment has. A larger space of 5.0m x 3.0m will be perfect for things out of bedroom two, such as furniture and appliances.
Large Storage Units (6.0M X 3.0M X 2.9M (H) to 8.0M X 3.0M X 2.9M (H))
The larger ones are well-suited for:
- Storing house contents during a move
- Business inventory, equipment, or office furniture
- For vehicle storage, including motorcycles, small boats, and classic cars
A 6.0m x 3.0m storage unit can hold the contents of a three-bedroom house, while an 8.0m x 3.0m unit can hold those from a five-bedroom house or a Storage unit for business use.

Choosing the Right Storage Unit Size
When choosing the proper storage unit, these factors will have to be kept in mind:
- Make an inventory list: Write down everything you plan to store and estimate the required space.
- Stacking and packing efficiency: To take advantage of the available vertical space, furniture can be piled up in boxes.
- Future storage requirements: If you expect to store even more items in the future, consider getting a slightly larger unit.
- Climate control: If delicate or valuable items are to be stored, a climate-controlled unit should be chosen to guard against changes in humidity and temperature.
Choosing the Right Storage Facility
While one of the crucial factors is storage unit sizes, selecting the right storage facility is equally important. Here are some things to remember when picking a facility:
1. Location and Accessibility
If you frequently need to access your belongings, you will want a storage facility close to your home or business. Such facilities with 24/7 access provide added convenience.
2. Security Features
Storage facilities should provide security systems such as gated access, CCTV cameras, on-site personnel, and locks to protect your belongings.
3. Climate-Controlled Options
The climate control unit should be placed when delicate items such as electronics, wooden furniture, and artwork need protection from extreme heat or humidity.
4. Pricing and Lease Flexibility
Compare their rates and check for lease flexibility. Some facilities may offer discounts for long-term rentals, while some will let you go short-term without obligation.
5. Customer Reviews and Reputation
Before choosing a facility, read online reviews and ask for recommendations on selecting a reputable storage company like Hills Self Storage.
