What Size Storage Unit Do I Need? Let’s Break It Down
Let’s start with the basics. Before you book anything, it's worth doing a bit of prep to figure out how much you’re actually storing. This section will help you think through what you're keeping, how often you'll need to access it, and what type of unit best suits your lifestyle.

FAQ: How Much Does a Storage Unit Cost
The cost of a storage unit depends on several factors, including the unit size, the location of the facility, and how long you plan to rent.
- Smaller Units like 10–25 sq ft are often very affordable, making them ideal for short-term or seasonal use.
- Larger Units (100+ sq ft) naturally cost more but offer excellent value for house moves or business needs.
Additionally, rates may vary by city, for example, self storage sizes in London tend to be more in demand and priced accordingly due to space constraints. At Storage King, we offer competitive pricing and flexible terms with no hidden fees.
