How Our Storage Unit Size Calculator Works

Enter the items you plan to store and the calculator estimates the total cubic footage you need, then matches it to the closest unit size available. It accounts for standard furniture dimensions and stacking space so you get a realistic recommendation — not just a rough guess.

Keep in mind the result is a starting point. If you're storing irregularly shaped items like bikes, kayaks, or large appliances, consider sizing up one level.

Storage Unit Sizes Explained

5×5 Storage Unit Small but mighty

About the size of a large closet. Fits boxes, small furniture, seasonal items, and sports equipment. Good for decluttering a single room or storing college dorm contents.

5×10 Storage Unit The most popular size

Fits the contents of a small bedroom — a queen mattress, dresser, boxes, and small appliances. A common choice for people between moves or downsizing temporarily.

10×10 Storage Unit One bedroom apartment

Fits the contents of a one bedroom apartment or a full home office. This is the sweet spot for most residential moves and business inventory storage.

10×15 Storage Unit One to two bedroom apartment

50 extra square feet over the 10×10. Fits larger furniture sets, multiple bedroom contents, or a combination of personal and business items.

10×20 Storage Unit Two to three bedroom home

Fits the contents of a two to three bedroom home, including large appliances and furniture. Also fits most standard vehicles if you need vehicle storage.

10×30 Storage Unit Large home or business

Our largest standard unit. Fits the contents of a four bedroom home, large business inventory, or oversized vehicles like trucks and trailers.

Tips for Choosing the Right Storage Unit

When in doubt, size up

It's cheaper to rent one larger unit than to realize mid-move you need a second one. A 10×10 costs only slightly more than a 5×10 but gives you significantly more flexibility.

Stack vertically to maximize space

All Bolt Storage units have standard ceiling heights. Place heavy, sturdy items on the bottom and stack lighter boxes on top to use the full height of the unit.

Consider climate control for sensitive items

If you're storing wood furniture, electronics, artwork, documents, or clothing long-term, a climate-controlled unit protects against heat, humidity, and cold. Most Bolt Storage locations offer this option.

Drive-up access saves time

If you're storing heavy or bulky items, a drive-up unit lets you load and unload directly from your vehicle — no carts or elevators needed. Available at most Bolt Storage locations.

Business storage works differently

If you're storing inventory, equipment, or documents, prioritize access frequency over size. A 10×10 or 10×15 with drive-up access is often more practical than a larger unit without it.
