Size Guide FAQs

Storage Unit Size Frequently Asked Questions

The questions Modern Storage® customers ask most about picking a unit size.

What size storage unit do I need?

The right storage unit size depends on what you're storing. A 5x5 (25 sq ft) holds closet overflow, seasonal items, and boxes. A 5x10 (50 sq ft) fits a studio apartment. A 10x10 (100 sq ft) fits a one-bedroom apartment — the most popular size. A 10x15 (150 sq ft) fits a two-bedroom apartment, a 10x20 (200 sq ft) holds a three-bedroom home, and a 10x30 (300 sq ft) handles a large home or business inventory.

If you're between sizes, choose the larger — month-to-month rentals at Modern Storage® mean you can downsize later.

How do I figure out what size storage unit I need?

Pick a storage unit size in four steps:

  1. Count the largest items first — beds, sofas, dressers, appliances. These set the floor space you need.
  2. Match those to a base size — studio = 5x10, one-bedroom = 10x10, two-bedroom = 10x15, three-bedroom = 10x20, large home or business = 10x30.
  3. Add a size up if you'll need walking aisle access during your rental (not just packed wall-to-wall).
  4. Choose climate-controlled instead of drive-up if you'll store furniture, electronics, photos, instruments, or anything for more than 3 months.

The AI Storage Size Finder runs this same logic in about 30 seconds — answer a few questions about what you're storing and it returns the right Modern Storage® size.

Quick decision framework:

  • Storing boxes, seasonal items, closet overflow → 5x5
  • Storing a studio or single room → 5x10
  • Storing a one-bedroom apartment → 10x10 (most popular size)
  • Storing a two-bedroom apartment → 10x15
  • Storing a three-bedroom home or one-car garage → 10x20
  • Storing a large home, two-car garage, or business inventory → 10x30

What fits in a 5x5 storage unit?

A 5x5 storage unit is roughly the size of a walk-in closet (25 square feet). It's the right call for apartment renters with extra stuff, college students between semesters, and document or photo archives. Typical Arkansas price range: $25-$45/month drive-up, $35-$60/month climate-controlled.

What fits in a 5x5 storage unit:

  • Up to 25 standard moving boxes
  • Holiday decorations and seasonal bins
  • A small dresser or nightstand
  • Photo albums, documents, and suitcases
  • Sporting equipment, hobby gear, and small tools

What fits in a 10x10 storage unit?

A 10x10 storage unit is 100 square feet — enough for the contents of a one-bedroom apartment. It's the most popular size at Modern Storage® because it balances space and price for most household moves and downsizing situations. Typical Arkansas price range: $80-$140/month drive-up, $110-$180/month climate-controlled.

What fits in a 10x10 storage unit:

  • Queen bedroom set with frame, mattress, and dresser
  • Living room set — couch, chair, and coffee table
  • One major appliance (washer, dryer, or refrigerator)
  • 15 to 20 standard moving boxes
  • A flat-screen TV, office equipment, and lamps

What fits in a 10x20 storage unit?

A 10x20 storage unit is 200 square feet — equivalent to a one-car garage. It's a common pick for three-bedroom home moves, whole-home renovations, and military PCS moves. Typical Arkansas price range: $150-$250/month drive-up, $200-$310/month climate-controlled.

What fits in a 10x20 storage unit:

  • Full living room, dining room, and three bedroom sets
  • Refrigerator, washer, dryer, and major appliances
  • Garage contents including tools and lawn equipment
  • Patio furniture, bicycles, and outdoor gear
  • Up to 75 standard moving boxes

Can I store a vehicle in a storage unit?

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.

What if I pick the wrong storage unit size?

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.

Are climate-controlled units available in every size?

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.

5x5 vs 5x10 Storage Unit — which is right for me?

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.

5x10 vs 10x10 Storage Unit — which is right for me?

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.

10x10 vs 10x15 Storage Unit — which is right for me?

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.

10x15 vs 10x20 Storage Unit — which is right for me?

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.

10x20 vs 10x30 Storage Unit — which is right for me?

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.

5x5 vs 10x10 Storage Unit — what is the difference?

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.

10x10 vs 10x20 Storage Unit — what is the difference?

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 vs large storage unit — how do I choose?

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.

Climate-Controlled 10x10 vs Standard 10x10 — what is the difference?

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.
