How to Choose the Right Storage Unit Size for Your Stuff

Ever stand in a storage aisle and wonder if the 5x5 box will hold everything or if you’re wasting money on a 10x10? You’re not alone. Picking the right size is all about knowing what you have, how you’ll pack it, and what you’ll use the space for.

Common Sizes and What They Hold

Most storage facilities offer a handful of standard sizes. Here’s a quick rundown:

5x5 (25 sq ft) – Fits a few boxes, a mattress, or a small piece of furniture. Good for seasonal items or a short‑term project.

5x10 (50 sq ft) – Holds a one‑bedroom’s worth of boxes, a couch, and a TV stand. Ideal for a studio or a single‑person move.

10x10 (100 sq ft) – Fits the contents of a typical one‑bedroom apartment. Think a queen bed, a dresser, several boxes, and a dining table.

10x15 (150 sq ft) – Perfect for a two‑bedroom space. You can store two beds, sofas, a dining set, and a lot of boxes.

10x20 (200 sq ft) and larger – These are for whole‑house moves, large inventories, or business stock.

Practical Steps to Pick Your Size

1. Make a list. Write down every item you plan to store. Group them by type – furniture, boxes, appliances.

2. Measure the big pieces. A couch, mattress, or table can take up a lot of space. Note their length, width, and height.

3. Box it up. A standard moving box (18×18×16 in) is about 3 cu ft. Count how many you have and multiply.

4. Add a safety margin. It’s wise to add 10‑20 % extra space for aisles, paths, and unexpected items.

5. Visualize. Sketch a simple floor plan on a piece of paper. Draw the unit outline and place each item. If things start to overlap, you need a bigger unit.

6. Consider climate control. If you’re storing wood furniture or electronics, a climate‑controlled unit may be worth the extra cost even if it’s a bit larger.

7. Think about access. You’ll want to reach items you’ll use often. If you plan to retrieve things regularly, choose a unit where you can walk through without moving everything around.

8. Check the facility’s layout. Some places have narrow aisles or low ceilings that affect usable space. Ask staff about any size restrictions.

By following these steps you’ll land on a size that fits without blowing your budget.

Remember, it’s easier to downsize later than to upgrade to a bigger unit and pay extra months. If you’re still unsure, many facilities let you upgrade within the first month – a handy safety net.

Now you’re ready to walk into the storage yard, know exactly what to look for, and walk out with a unit that’s just right. Happy storing!
