Preparing for the big move? Or is your business inventory quickly outgrowing your current workspace? What’s the best solution when you need a lot of room?
If your life or business is starting to feel cluttered, a large storage unit can be the perfect solution to give you the space you need.
But how much can you actually fit inside a large unit, and which option is the right one for your needs? Let’s find out. Plus, we’ll give you some expert tips to help you make the most of your space at Lock Box Self Storage, no matter which size unit you rent.
What is Considered a Large Storage Unit?
How much space will you really be getting when you rent a large storage unit?
Typically, a large unit is 200 square feet or larger – approximately the size of a one-car garage. Depending on the space you rent, your storage unit may be able to store the packed contents of your whole house.
At Lock Box Self Storage, we offer multiple size options, so you’ll be able to find the perfect unit for you. We offer:
10’x20’ Units
Our 10’x20’ units are 200 square feet. They can hold the contents of a two- or three-bedroom home, including a fridge, washer and dryer, three mattress sets, a dining room set, bookcases, couches and additional boxes.
10’x20’ units are also good for parking cars, snowmobiles, jet skis and other smaller vehicles.
10’x25’ Units
Our 10’x25’ units are 250 square feet. They give you a little more room and can store a three- or four-bedroom home. This space can fit a couple of couches and mattress sets, an oversized armchair, dining room set, fridge, washer and dryer, entertainment nook, bookcases and more.
10’x30’ Units
Our 10’x30’ units are 300 square feet, which is the size of an oversized one-car garage. They can fit the contents of a three- to four-bedroom house. This space can hold everything our 10’x25’ unit can, while giving you a little more room to work with and to store oversized furniture.
Why You Might Need a Large Storage Unit
Large storage units are one of the most versatile and affordable options out there if you need a lot of space to store your stuff. Here are some of the most common reasons why you might consider renting one:
You’re Moving or Renovating Your Home
Chances are, you don’t want to risk your belongings getting damaged or stolen during the big move or renovation. Having a conveniently located, ultra-secure space to keep your belongings means you have one less thing to worry about during your move to or from Mount Juliet.
Or, if you’re doing a big home renovation, and need to move all your furniture and appliances, a large storage unit will keep all your furniture and appliances safe until the job is done.
You Want to Store Oversized Belongings
King size mattresses, washers and dryers, fridges and other oversized belongings are bulky and can take up a lot of space. Giving yourself more room to work with helps you avoid the potential of damaging your belongings while moving them into and out of storage.
You Need More Business Storage
Large storage units aren’t just for homeowners. If you’re a small business owner in the Mount Juliet area, renting a unit can help you organize your inventory and documents, keep valuable tools safe and help your business run more efficiently.
You Want Indoor Vehicle Storage
Outdoor vehicle storage is a great, affordable solution to keep your vehicle safe. But if you’re looking to fully protect your vehicle from the elements, why not rent a fully-enclosed storage unit? Large units are around the size of a one-car garage, making them a great solution for cars, bikes, jet skis and other smaller vehicles.
Our Tips for Success
Large storage units give you a lot of room to work with, but if you’re storing the contents of your whole home, space can run out quickly. Here are just a few of our top tips to help make your self storage experience smoother.
Use Our Storage Calculator
Many people are hesitant to rent a storage unit simply because they’re unsure which size unit will work best for everything they need to store.
While you can dig out your tape measure and do the math yourself, why overcomplicate it? Use our free, handy self storage calculator tool instead. It’s easy!
Make a list of all the furniture and estimate the number of boxes you’ll be storing in your unit. Then, simply select the items in the calculator. It will provide you with a suggestion of a unit, as well as a visual representation that suggests how you might arrange your belongings inside your unit.
Leave Some Room
It might be tempting to go with the smallest unit possible and make use of every square inch of space available to you. However, instead of struggling to fit your belongings into too small of a space, we recommend opting for a slightly larger unit and leaving yourself a little bit of room to work with.
Creating aisles or using shelves helps you stay organized, avoid frustration and damaged items, and ensures that you’ll always be able to quickly find the items you’re looking for. This is especially important if you’re planning on using your unit long-term.
Label Boxes Clearly
No matter if you’re storing business inventory or all your household belongings, keeping your unit organized is essential to your success. Label all of your boxes with clear, detailed descriptions, such as “office bookshelves,” “winter holiday decorations” or “2024 paperwork.”
As well, clearly label fragile items and store them away from heavy or bulky items to avoid potential damage.
Ask the Storage Experts
No one knows storage units better than the people who work with them every day.
If you’re still unsure which size unit you need, why not give the experts a call? Our local, on-site team at Lock Box Self Storage has all the answers you need to help you find the perfect large storage unit in Mount Juliet for your needs.
