Choosing the Right Size Unit

Still not sure what the ideal storage size would be for all your belongings? Let’s look at a few tips on choosing the right one.

Take an Inventory

Start by taking an inventory of everything you need to store. This includes your furniture and appliances, storage boxes, and totes. Measure your larger items and consider any items that may be of an irregular shape and may be more awkward to store.

Use Size Guides

You can also use a size guide to help you find the right storage unit size. A guide like this can give you more of a visual representation of each unit to help you determine how much storage space you need.

Use the Moving Truck

If you are using a moving truck to transport your items to storage, you can use the truck to indicate how much space you will need. For example, if your moving truck is 25 feet, your items should fit nicely into a 10’x20’ unit.

Go Bigger

If you are still unsure, you want to make sure you have slightly more space than you need instead of not having enough. If you feel you might be underestimating your needs, go up to the next larger size. The larger size also allows you to create a pathway in the unit, making it easier to access your items.

Know Your Storage Unit Dimensions

Storage units will typically be sized according to the width, so you can get the square footage. However, you also need to consider the ceiling height because this is usable space that helps stack items high, saving space.

Most storage units have a typical ceiling height of at least 8 feet. You will quickly find that this little bit of extra space is good for stacking storage boxes. You can even turn your longer items like your couch and bed to the side to accommodate your other furniture.

Storage Unit Sizes

Again, storage units come in various sizes that meet the needs of different customers. You may be looking to store the contents of an entire three-bedroom home, or maybe you just want a space to store away seasonal items until it is time to put them to use again.

Picking the right size storage unit for the items you have to store can save you time and money. You don’t want to end up paying more for space you aren’t utilizing. You also want to avoid having to rent a second storage unit after finding out you are running short on space.

Now let’s take a closer look at the sizes available for you to rent as your extra storage space. This guide will help you pick the best option to make your storage experience easier and more affordable.

Tips for Packing Your Storage Unit

After you’ve chosen your storage unit size, plan ahead before moving items in.

Make sure you have all the packing supplies you need for moving and storage. You also want to insure your items in storage.

Before moving your items in, be sure to inspect the storage space. Make sure it is an adequate size for your needs, is well lit, and has no issues. You will then want to purchase a high-quality, hardened steel lock to secure the unit.

When packing boxes, make sure they are packed to capacity. A partially full box may collapse or tip. If you have heavy items, pack them in smaller boxes that are easier to lift.

It also helps to label all your boxes so you can easily find what you need.
