How Storage Unit Sizes Compare: Quick Reference Table

Choosing the right storage unit size prevents paying for unused space or cramming belongings into a unit that is too small.

The table below shows exact dimensions, capacity, and local pricing for Gunnison and Crested Butte facilities.

Unit Size Square Feet Comparable To Best For Local Price Range

5x5 Storage Units: The Walk-In Closet Solution

A 5x5 storage unit measures 25 square feet with standard 8-foot ceilings, creating 200 cubic feet of storage space. This size works for Western Colorado University students storing dorm contents over summer, seasonal residents rotating ski and bike gear, or anyone decluttering a spare room. The compact footprint keeps monthly costs between $95 and $115 in the Gunnison Valley.

What Fits in a 5x5 Unit

According to industry storage guidelines from Hooked Home , a 5x5 unit accommodates approximately 8 to 12 medium moving boxes stacked floor to ceiling. Add a small dresser, nightstand, or twin mattress set and you reach capacity. The key is vertical stacking; place heavy boxes on the bottom and lighter items on top.

Typical 5x5 contents include:

  • 8 to 12 medium boxes (18x18x16 inches each)
  • One small dresser or chest of drawers
  • Seasonal clothing in wardrobe boxes
  • Ski equipment: 2 to 3 pairs of skis, boots, poles
  • Mountain bikes: 1 to 2 bikes hung vertically
  • Small appliances: microwave, coffee maker, small TV
  • Camping gear: tent, sleeping bags, cooler

The Riverland location in Crested Butte offers 5x5 interior upstairs units at $95 per month. The North Gunnison facility provides drive-up 5x5 units at $115 per month, ideal for renters who need frequent access to seasonal gear without climbing stairs.

5x5 Unit Limitations

A 5x5 unit will not fit a standard sofa (typically 7 to 8 feet long), queen or king mattress sets, or large appliances like refrigerators. If your inventory includes any furniture piece longer than 5 feet, consider upgrading to a 10x10 unit. The Self Storage Association reports that 35% of customers who start with a 5x5 upgrade within 6 months due to underestimating their needs.

10x10 Storage Units: The One-Bedroom Solution

A 10x10 storage unit provides 100 square feet, equivalent to half a standard one-car garage. This size represents the most popular choice nationwide, accounting for approximately 40% of all storage rentals according to industry data from Vail Airport Storage's 2026 market analysis. In Gunnison and Crested Butte, 10x10 units range from $229 to $337 per month depending on location and climate control features.

What Fits in a 10x10 Unit

A 10x10 unit comfortably holds the contents of a one-bedroom apartment or a significant portion of a two-bedroom home. The 10-foot width accommodates standard furniture pieces including sofas, queen beds, and dining tables. Most renters can fit a living room set, bedroom furniture, and 20 to 30 boxes in this size.

Typical 10x10 contents include:

  • One standard sofa (7 to 8 feet)
  • Queen or king mattress and box spring
  • Bedroom set: dresser, nightstands, bed frame
  • Dining table with 4 chairs
  • 20 to 30 medium moving boxes
  • Major appliances: washer, dryer, or refrigerator
  • Multiple sets of ski and bike equipment
  • Patio furniture set

10x10 Pricing Across Gunnison Valley Locations

Discount Self Storage operates 10x10 units at multiple facilities with varying price points based on features. The Elk Mountain Storage location in downtown Crested Butte offers 10x10 interior units at $229 per month with a current promotion of 50% off one month. This location provides LED lighting and monthly pest control.

Location Unit Type Monthly Rate Key Features
Elk Mountain (Crested Butte) Interior Upstairs $229 LED lighting, pest control, 50% off first month
North (Gunnison) Drive-Up $245 Ground floor, vehicle access
Riverland (Crested Butte) Interior Upstairs $245 RV/boat parking available on-site
Slate River (Crested Butte) Climate-Controlled $337 Heated, video surveillance, discounted from $371

The climate-controlled option at Slate River Storage costs $92 more per month than standard units but protects temperature-sensitive items from Gunnison County's extreme temperature swings. Winter temperatures regularly drop below -20°F while summer highs reach 90°F, creating a 110-degree annual range that damages wood furniture, electronics, and leather goods.

10x20 Storage Units: The Full Household Solution

A 10x20 storage unit provides 200 square feet, equivalent to a standard one-car garage. This size accommodates the complete contents of a three to four bedroom home or serves as vehicle storage for cars, boats, ATVs, and snowmobiles. In Gunnison and Crested Butte, 10x20 units range from $365 to $693 per month, with the highest prices reflecting climate-controlled vehicle storage.

What Fits in a 10x20 Unit

The 20-foot depth of these units allows parking a standard vehicle with room remaining for boxes and equipment. Second-home owners in Crested Butte frequently use 10x20 units to store an entire household between visits, eliminating the need to furnish and unfurnish vacation properties seasonally.

Typical 10x20 contents include:

  • Complete living room: sofa, loveseat, coffee table, entertainment center
  • Full dining room: table, 6 to 8 chairs, china cabinet
  • Master bedroom: king bed, dresser, armoire, nightstands
  • Second bedroom furniture set
  • 40 to 50 moving boxes
  • Major appliances: refrigerator, washer, dryer
  • One standard vehicle (sedan, SUV, or small truck)
  • Boat up to 18 feet with trailer
  • Multiple ATVs or snowmobiles

10x20 Options for Vehicle Storage

Vehicle storage represents a primary use case for 10x20 units in mountain communities. The Crested Butte location on Buckley Drive offers drive-up 10x20 units at $425 per month with 8-foot ceilings and daily snow removal during winter months. This eliminates the 30-minute drive to Gunnison for Crested Butte residents needing vehicle storage.

For temperature-sensitive vehicles, classic cars, or boats with electronics, the climate-controlled 10x21 units at Slate River Storage provide heated storage at $693 per month (discounted from $762). All units include digital video surveillance, LED lighting, and monthly pest control.

Choosing Between Drive-Up and Interior Units

Drive-up units allow direct vehicle access to your storage door, eliminating the need to carry items through hallways or up stairs. Interior upstairs units cost 15 to 25 percent less but require more effort during loading and unloading. The choice depends on what you store and how often you access it.

When to Choose Drive-Up Access

Drive-up units work best for heavy items, frequent access, and vehicle storage. If you plan to visit your unit more than twice per month or store items over 50 pounds, the convenience justifies the higher cost. The North Gunnison and Airport locations specialize in drive-up access with wide drive aisles for easy maneuvering.

Choose drive-up when storing:

  • Furniture requiring dollies or hand trucks
  • Appliances (refrigerators, washers, dryers)
  • Vehicles, boats, ATVs, or snowmobiles
  • Business inventory requiring regular access
  • Items you access weekly or monthly

When Interior Upstairs Units Make Sense

Interior upstairs units at Riverland and Elk Mountain Storage offer lower monthly rates for renters who store lighter items or access their unit infrequently. Western Colorado University students storing dorm contents over summer benefit from the savings since they only access the unit twice per year.

Climate Control: When Gunnison Weather Demands It

Gunnison holds the record for Colorado's coldest recorded temperature at -60°F (January 1951) and regularly experiences winter lows of -20°F to -30°F. Summer temperatures reach 85°F to 90°F. This 110-degree annual temperature swing causes expansion and contraction damage to wood, warping of vinyl records and photographs, and condensation that leads to mold growth.

Items Requiring Climate Control

Climate-controlled units at Slate River Storage maintain temperatures between 55°F and 80°F year-round through active heating systems. The $92 to $108 monthly premium over standard units protects investments that cost thousands to replace.

Store these items in climate-controlled units:

  • Wood furniture: antiques, pianos, guitars
  • Electronics: computers, televisions, audio equipment
  • Leather goods: furniture, clothing, accessories
  • Photographs, artwork, and documents
  • Wine collections (requires consistent 55°F to 58°F)
  • Medical equipment and pharmaceuticals
  • Vinyl records and musical instruments

The SafeLease tenant protection plan covers damage from temperature-related issues including mold and mildew, but prevention through climate control costs less than replacement.

Storage Solutions by User Type

Different Gunnison Valley residents have distinct storage needs based on their lifestyle and property situation. The following recommendations come from patterns observed across six facilities serving Gunnison and Crested Butte.

Western Colorado University Students

Students typically need storage from May through August, a 3 to 4 month period between academic years. A 5x5 unit at $95 to $115 per month stores dorm contents including a mini-fridge, microwave, bedding, clothing, and 8 to 12 boxes. Total summer storage cost: $285 to $460. The North Gunnison location on Highway 135 sits 5 minutes from campus.

Second-Home Owners

Vacation property owners in Crested Butte often store furniture and household items between visits rather than leaving them in unoccupied homes. A 10x10 unit at $229 to $245 per month stores one bedroom's worth of furniture and seasonal gear. For complete household storage, a 10x20 unit at $365 to $425 per month accommodates everything.

Seasonal Workers and Renters

Ski resort employees and seasonal workers frequently move between winter and summer housing. A 5x5 or 10x10 unit bridges the gap between leases. Month-to-month flexibility means no long-term commitment; cancel anytime with 30 days notice.

RV and Boat Owners

Gunnison Valley's proximity to Blue Mesa Reservoir (Colorado's largest body of water) creates demand for boat storage. A 10x20 drive-up unit accommodates boats up to 18 feet with trailers. For larger vessels or RVs, Elk Mountain Storage and Slate River Storage offer units up to 19x35 feet (665 square feet) starting at $157 per month.

How to Estimate Your Storage Needs

The most accurate way to determine unit size involves creating a room-by-room inventory. List every item you plan to store, then use these volume estimates to calculate total cubic feet needed.

Furniture Volume Estimates

Item Approximate Cubic Feet Notes
Standard sofa 50 to 70 cu ft Stand on end to save floor space
Queen mattress set 60 to 80 cu ft Store upright against wall
Dresser 30 to 40 cu ft Fill drawers with soft items
Dining table (6 chairs) 45 to 60 cu ft Stack chairs on table
Refrigerator 40 to 60 cu ft Clean and prop door open
Medium moving box 3 to 4 cu ft Standard 18x18x16 inches

A 5x5 unit with 8-foot ceilings provides 200 cubic feet. A 10x10 provides 800 cubic feet. A 10x20 provides 1,600 cubic feet. Divide your total inventory cubic feet by unit capacity, then add 15 to 20 percent for aisle space and access.

Frequently Asked Questions

What size storage unit do I need for a one-bedroom apartment?

A 10x10 unit (100 square feet) fits the contents of a typical one-bedroom apartment including a sofa, bed, dresser, dining set, and 20 to 30 boxes. If you own minimal furniture, a 5x10 unit may suffice. At Discount Self Storage, 10x10 units in Gunnison and Crested Butte range from $229 to $337 per month.

Can I store a car in a 10x20 storage unit?

Yes. A 10x20 unit measures 10 feet wide by 20 feet deep, accommodating most sedans, SUVs, and small trucks. Standard parking spaces measure 9x18 feet, so a 10x20 unit provides adequate clearance. Drive-up 10x20 units at the North Gunnison and Airport locations include large roll-up doors for easy vehicle entry.

Is climate-controlled storage necessary in Gunnison?

Climate control is necessary for temperature-sensitive items stored longer than 3 months. Gunnison's temperature range from -30°F to 90°F causes wood to crack, electronics to fail, and leather to dry and crack. Climate-controlled units at Slate River Storage maintain 55°F to 80°F year-round for $244 to $693 per month depending on size.

How much does storage cost in Crested Butte versus Gunnison?

Crested Butte storage costs 10 to 20 percent more than Gunnison due to higher real estate costs and convenience for local residents. A 10x10 unit costs $229 to $337 in Crested Butte compared to $245 in Gunnison. The premium eliminates the 30-minute drive between towns for Crested Butte residents.

What is the difference between drive-up and interior storage units?

Drive-up units allow you to park directly at your storage door and load items without stairs or hallways. Interior units require walking through a building, often up stairs, but cost 15 to 25 percent less. Choose drive-up for heavy items, frequent access, or vehicle storage. Choose interior for lighter items and lower monthly costs.

Do I need insurance for my storage unit?

Storage facility insurance typically covers the building, not your belongings. The SafeLease tenant protection plan available at all Discount Self Storage locations covers burglary, fire, water damage, vandalism, and rodent damage with a $100 deductible (waived for burglary with approved locks). Plans are included in rental fees. Learn more about tenant protection coverage options.
