What Fits in Each Size

3×4 (12 sq ft) — Starting at $30/mo

Our smallest and most affordable unit. Think of it as a secure storage locker. It holds 4–8 standard moving boxes, a couple of bags of clothing, seasonal decorations, or a small collection of documents and files. Ideal for college students storing a few essentials, or anyone who just needs a compact overflow space.

5×5 (25 sq ft) — $60 Standard / $74 Climate-Controlled

About the size of a large closet. Fits a small dresser or bookshelf, a desk chair, 10–12 boxes, and seasonal gear like holiday decorations, camping equipment, or winter clothing. Popular with apartment renters in Macon who want to free up a closet or spare room.

5×10 (50 sq ft) — $83 Standard / $102 Climate-Controlled

The size of a walk-in closet. Holds a complete bedroom set — queen mattress (on its side), dresser, nightstand — plus 10–15 boxes. This is the go-to size for Mercer students clearing out an apartment for the summer, staging a room for a home sale, or storing business records and inventory.

15×5 (75 sq ft) — $102/mo

A long, narrow unit that works well for items that need length — rolled carpets, shelving units, long tables, or kayaks. Also good for organizing business inventory that you need to access frequently, since the narrow layout lets you reach items without climbing over boxes.

10×10 (100 sq ft) — $99 Standard (on sale) / $132 Climate-Controlled

Our most popular size. Holds the contents of a typical one-bedroom apartment: couch, queen bed, dresser, small dining set, TV, and 20–30 boxes. This is the size most Macon residents choose when relocating, renovating, or downsizing. Two Mercer students can share one 10×10 and save significantly compared to each renting a 5×5.

10×15 / 15×10 (150 sq ft) — $132 Standard / $178 Climate-Controlled

Holds the contents of a two-bedroom home. Two bedroom sets, living room furniture, kitchen boxes, and miscellaneous items. A strong choice for families renovating their home or military families at Robins AFB storing household goods during a PCS transition.

10×20 / 20×10 (200 sq ft) — $148/mo

Fits a three-bedroom home or a vehicle plus furniture. At 200 square feet, you can fit a couch, two bedroom sets, a dining table, appliances, and 40+ boxes. This is the most popular size for Robins AFB families storing an entire household and for homeowners clearing out a house for staging or major renovation.

10×25 (250 sq ft) — $167/mo

Ideal for large homes or anyone who needs extra breathing room. Holds a four-bedroom home’s contents or a vehicle alongside full household furniture. Businesses use this size for significant inventory or equipment storage.

15×15 (225 sq ft) — $217/mo Climate-Controlled

A spacious, square climate-controlled unit. The shape makes it easy to organize and access items from multiple sides. Best for businesses storing sensitive inventory, families with large collections of furniture and valuables, or anyone who needs a climate-protected space larger than a 10×15.

15×20 (300 sq ft) — $247/mo Climate-Controlled

Our largest climate-controlled option. Think of it as a small climate-controlled warehouse. Holds an entire large household with room to spare, or significant business inventory that needs temperature and humidity protection. Ideal for antique dealers, art collectors, and businesses with sensitive stock.

20×40 (800 sq ft) — $400/mo

Our largest unit overall — the size of a two-car garage and then some. This is built for commercial use: warehousing inventory, storing vehicles and equipment, or holding an entire large household with vehicles alongside it. Contractors, landscaping companies, and businesses with heavy equipment regularly use this size.

How to Choose the Right Size

1. List your large items first — Furniture, mattresses, and appliances determine your minimum unit size.
2. Estimate your boxes — A typical bedroom produces 10–15 moving boxes. A kitchen adds another 10–15.
3. Decide on standard vs. climate-controlled — If your items are durable (plastic bins, metal tools, outdoor gear), standard saves you money. If they are sensitive (wood, electronics, paper, fabric), go with climate-controlled.
4. Add a small buffer — Leave a narrow aisle down the center so you can access items in the back without moving everything.
5. Use our calculator — Our free storage calculator asks what you are storing and recommends the right size automatically.

When in doubt, go one size up. The modest cost difference is worth the convenience of easy access and room to add items later.
