What Size Storage Unit Do You Need?

A 10x10 storage unit (100 sq ft) fits a typical one-bedroom apartment, including a queen mattress and frame, dresser, sofa, coffee table, TV, dining set, and 15-20 boxes. If you have a large sectional sofa or oversized furniture, step up to a 10x15. If you are only storing the bedroom — not the full apartment — a 5x10 (50 sq ft) is enough.

A 10x15 storage unit (150 sq ft) fits a typical two-bedroom apartment, including two mattress sets, dressers, a sofa, dining set, TV stand, and 20-30 boxes. If you have an oversized sectional, multiple beds beyond two, or you want breathing room to walk inside the unit, step up to a 10x20 (200 sq ft).

A 10x20 storage unit (200 sq ft) fits a typical three-bedroom home, including multiple mattress sets, dressers, a full living room, dining set, appliances, and 30-50 boxes. It is roughly the size of a one-car garage. For four- and five-bedroom homes or homes with extensive furniture, choose a 10x30 (300 sq ft) instead.

A 5x5 storage unit is 25 square feet — 5 feet wide by 5 feet deep with an 8-foot ceiling — for a total of about 200 cubic feet of storage space. It is roughly the size of a single hall closet and is the smallest Modern Storage® unit size. It fits 15-20 boxes, a small dresser, seasonal items, holiday decor, and college dorm gear.

A 5x10 storage unit is 50 square feet — 5 feet wide by 10 feet deep with an 8-foot ceiling — for a total of about 400 cubic feet of storage space. It is roughly the size of a walk-in closet and is one of the most popular Modern Storage® unit sizes. It fits the contents of a studio apartment or single bedroom, including a mattress set, dresser, small sofa, and 10-15 boxes.

A 10x10 storage unit is 100 square feet — 10 feet wide by 10 feet deep with an 8-foot ceiling — for a total of about 800 cubic feet of storage space. It is roughly the size of a small bedroom and is the most-rented Modern Storage® unit size in Arkansas. It fits the contents of a one-bedroom apartment, including a queen bed, dresser, sofa, dining set, TV, and 15-20 boxes.

A 10x20 storage unit is 200 square feet — 10 feet wide by 20 feet deep with an 8-foot ceiling — for a total of about 1,600 cubic feet of storage space. It is roughly the size of a one-car garage. It fits the contents of a three-bedroom home, including multiple mattress sets, full living and dining rooms, appliances, and 30-50 boxes. It is also large enough to store a single mid-size car.

A king-size mattress and frame fit in any Modern Storage® unit size from a 5x10 upward when stored on edge (mattress upright against a wall). A 5x10 fits the king set plus a few small items. A 10x10 fits the king set plus a one-bedroom apartment worth of furniture. For a king bedroom plus a living room and dining set, choose a 10x15.

A full-size sectional sofa fits in a 10x10 storage unit (100 sq ft) when broken down into individual pieces. If you also need to store other furniture or a full bedroom, step up to a 10x15. Oversized sectionals (10+ feet long when assembled) may need a 10x15 even when stored alone, depending on the configuration of the pieces.

The smallest Modern Storage® storage unit is a 5x5 (25 square feet) — about the size of a single closet. It fits 15-20 boxes, a small dresser, holiday decor, and college dorm storage. For even smaller needs, like document storage or a single box of records, consider sharing a 5x5 with a friend or a colleague — though Modern Storage® rentals are typically single-customer.

The largest standard Modern Storage® indoor storage unit is a 10x30 (300 square feet) — roughly the size of a two-car garage. It fits the contents of a four- or five-bedroom home plus garage contents, or a full business inventory. For boats, RVs, oversized trailers, and oversized vehicles, Modern Storage® also offers outdoor parking spaces at participating locations including Maumelle Blvd, Bryant, Lowell, and Bentonville.

Choose climate-controlled storage for furniture, electronics, documents, photos, antiques, and anything stored more than ~3 months in Arkansas. Climate-controlled units stay between roughly 59°F and 79°F year-round and protect against Arkansas summer humidity and winter cold. Choose drive-up storage for tools, plastic bins, patio furniture, outdoor gear, and short-term storage where temperature changes don't matter — it costs less and lets you pull a vehicle directly to the unit door for loading.

Yes, at select Modern Storage® locations. A 10x20 storage unit fits a smaller car or motorcycle. A 10x30 storage unit can accommodate a larger vehicle, a small boat, or a trailer. For RV and boat storage specifically, see the Boat & RV Storage page — five Modern Storage® locations (Lowell, Shackleford, Bentonville, Springdale, Maumelle) offer outdoor and covered vehicle parking sized for longer rigs.

It happens often — and it's an easy fix. Modern Storage® rentals are month-to-month, so if a 5x10 turns out too small, you can move up to a 10x10 at the same facility without breaking a contract. Use the AI Size Finder tool on this site for a personalized recommendation, or call the local Modern Storage® team and we'll help size you right the first time.

Every Modern Storage® location offers climate-controlled units in 5x5 through 10x20 sizes, with 10x30 availability varying by facility. Climate-controlled storage keeps temperature and humidity more stable than an outdoor unit — the right call for furniture, electronics, documents, photos, art, and instruments. See the Climate-Controlled Storage page for the full breakdown.

A 5x5 storage unit offers 25 square feet of space and is ideal for boxes, seasonal decorations, small furniture, or business records. A 5x10 doubles the storage area to 50 square feet and can hold the contents of a small bedroom, including a mattress set, dresser, and multiple boxes. If you're storing more than a few items or need room to access belongings, a 5x10 is often worth the extra space.

A 5x10 unit provides 50 square feet, while a 10x10 provides 100 square feet. A 10x10 can typically hold the contents of a one-bedroom apartment, making it a popular choice during moves. If you're storing furniture from multiple rooms, the 10x10 offers significantly more flexibility.

A 10x15 storage unit provides 50% more space than a 10x10. While a 10x10 works well for a one-bedroom home, a 10x15 is often better for a two-bedroom home, larger furniture sets, appliances, and business inventory.

A 10x20 storage unit can often hold the contents of a three-bedroom house, including large appliances and multiple furniture sets. A 10x15 is a strong middle-ground option for families that need extra storage without paying for unused space.

A 10x30 unit offers 300 square feet of storage and is often used for large household moves, commercial inventory, or vehicle storage. A 10x20 works well for most residential storage needs, while a 10x30 is ideal for major transitions or business use.

The difference is substantial. A 5x5 is similar to a small closet, while a 10x10 is roughly the size of half a standard garage. If you're storing furniture, appliances, or an entire room's contents, a 10x10 is usually the better choice.

A 10x20 provides twice the floor space of a 10x10. While a 10x10 is suitable for apartment storage, a 10x20 can accommodate the contents of a multi-bedroom home, making it a common choice during relocations.

Small storage units are ideal for seasonal items, boxes, and a few pieces of furniture. Large storage units work better for household moves, business inventory, vehicles, and long-term storage. Choosing the right size helps avoid paying for unused space.

Both units provide the same amount of space, but climate-controlled storage maintains more stable temperatures and humidity levels. If you're storing electronics, wooden furniture, antiques, documents, or collectibles, climate-controlled storage provides additional protection.
