How Big Is a 10x10 Storage Unit?
A 10x10 storage unit measures 10 feet wide by 10 feet deep, providing 100 square feet of floor space. Most facilities offer ceiling heights between 8 and 10 feet, giving you 800 to 1,000 cubic feet of total volume. This equals roughly half a standard one-car garage.
According to Public Storage's size guide , a 10x10 unit typically holds the contents of a one to two bedroom apartment, including a queen-size mattress set, dresser, small dining table with chairs, sofa, and 20 to 30 medium boxes. The 10x10 size remains the most rented unit nationwide, accounting for approximately 25 percent of all self storage rentals.
What Actually Fits in a 10x10 Unit
Real-world capacity depends on furniture dimensions and packing efficiency. Here is what fits in a 10x10 unit with moderate stacking:
- Queen or king mattress set (stored vertically against wall)
- Dresser and nightstands
- Three-seat sofa or sectional (disassembled if possible)
- Dining table with four chairs
- Television and entertainment center
- Washer and dryer (stacked or side by side)
- 20 to 30 medium moving boxes
- Bicycles, camping gear, or sports equipment

How to Calculate Your Storage Unit Size
Follow this four-step process to determine your exact storage needs without overpaying or running short on space.
Step 1: Inventory Your Items
Walk through each room and list major furniture pieces. Count beds, sofas, tables, chairs, dressers, and appliances. Note unusual items like pianos, exercise equipment, or large artwork. For boxes, estimate based on room contents: bedrooms typically generate 5 to 10 boxes each, kitchens produce 10 to 15 boxes, and garages vary widely.
Step 2: Measure Large Items
Record dimensions for your largest pieces. A standard sofa measures approximately 7 feet long by 3 feet deep. King mattresses measure 6.5 feet by 6.5 feet. Dining tables range from 5 to 8 feet long. These measurements help determine minimum width requirements.
Step 3: Consider Access Needs
Decide how often you need to retrieve items. Monthly access requires walking aisles between boxes, adding 20 to 30 percent more space. Long-term storage with rare access allows tight packing. Business inventory with weekly access needs maximum accessibility.
Step 4: Use the Room Count Method
As a quick estimate, add your total rooms and match to unit size. One to two rooms equals 5x10. Three to four rooms equals 10x10. Five to six rooms equals 10x15. Seven or more rooms equals 10x20 or larger. Adjust up if you have oversized furniture or down if items are minimal.

Tips to Fit More in a Smaller Storage Unit
Efficient packing reduces your required unit size by 25 to 40 percent, saving $25 to $100 monthly. Professional organizers and moving companies recommend these techniques.
Disassemble Furniture
Remove legs from tables and desks. Take apart bed frames. Detach sofa cushions and store separately. Disassembly reduces furniture footprint by 30 to 50 percent and prevents scratches during stacking.
Use Uniform Box Sizes
Standard moving boxes (18x18x16 inches) stack efficiently without wasted space. Avoid mixing random boxes, bags, and containers. Home Depot, Lowe's, and U-Haul sell uniform box kits ranging from $30 to $75.
Stack Vertically
Most storage units offer 8 to 10 foot ceilings. Stack sturdy boxes and bins to maximize vertical space. Place heavy items on bottom, lighter items on top. Use freestanding shelving units for frequently accessed items.
Create a Center Aisle
If accessing items regularly, leave a 2-foot aisle down the center. Place frequently needed items near the door. Label all boxes on sides facing the aisle for quick identification.
Store Mattresses Vertically
Standing mattresses against walls saves significant floor space. Use mattress bags (available for $10 to $25) to protect against dust and moisture. King mattresses stored vertically occupy only 6.5 square feet instead of 42 square feet.
When to Choose a Larger Storage Unit
Upgrading one size typically costs $20 to $50 more monthly but provides significant convenience. Consider sizing up in these situations.
Frequent access needs: Business owners, seasonal workers, and anyone retrieving items weekly benefit from extra maneuvering room. Walking aisles prevent moving boxes to reach items in back.
Fragile or valuable items: Antiques, artwork, and electronics need buffer space to prevent stacking damage. Extra room allows protective padding and careful placement.
Future additions expected: If you plan to add items over coming months, start with the larger size. Moving to a bigger unit later requires re-loading everything.
Inexperienced packers: Without professional packing skills, items rarely fit as tightly as estimates suggest. The extra cushion prevents overflow problems on moving day.
Are Storage Units Actually the Advertised Size?
Storage unit dimensions represent exterior measurements, not interior usable space. Wall thickness, door frames, and support columns reduce actual floor space by 3 to 8 percent. A 10x10 unit typically provides 95 to 97 square feet of usable floor area.
The Self Storage Association requires facilities to disclose that advertised sizes are approximate. Always visit the specific unit before signing a lease. Walk inside, measure if needed, and visualize your largest items fitting through the door. Our facility photos and video tour show actual unit interiors at Moab Self Storage.
How Much Does a 20x20 Storage Unit Hold?
A 20x20 storage unit provides 400 square feet, equivalent to a two-car garage. This size holds five to six bedroom home contents, multiple vehicles, or substantial commercial inventory. With 8-foot ceilings, total volume reaches 3,200 cubic feet.
Typical 20x20 contents include complete household furniture for a large home, two vehicles, business equipment and inventory, or estate contents from multiple family members. Monthly costs range from $300 to $600 depending on location and features.
Most residential customers find 10x20 units sufficient. The 20x20 size serves commercial users, estate consolidation, and situations requiring vehicle storage alongside household goods.
Is a 10x20 Storage Unit Big Enough?
A 10x20 storage unit accommodates three to four bedroom home contents with room to spare. This size equals a standard one-car garage at 200 square feet. According to industry data, 10x20 units satisfy 85 percent of full-household storage needs.
The 10x20 size works for complete home moves during relocation or renovation, vehicle storage for cars, trucks, or motorcycles, combined household and vehicle storage, and business inventory requiring forklift or pallet access. For larger homes exceeding 2,500 square feet with fully furnished rooms, consider 10x25 or 10x30 sizes.
Drive-Up Storage Benefits for Moab Residents
Drive-up storage units allow direct vehicle access to your unit door. This feature saves significant time and physical effort compared to interior units requiring dollies and elevators.
For Moab's outdoor recreation community, drive-up access proves essential. Loading kayaks, mountain bikes, paddleboards, and camping gear directly from your vehicle takes minutes instead of multiple trips. Tour operators and outfitters frequently access inventory, making ground-level convenience critical.
Moab Self Storage offers exclusively drive-up units with 24/7 access. Our fully paved facility at 1081 S Main Street provides easy loading regardless of weather. As a locally owned storage facility , we understand the unique storage needs of Moab Valley residents, from seasonal workers to outdoor enthusiasts to local businesses.
