10x20 vs 10x25 Storage Unit: What Actually Fits

Glenwood Springs Storage • November 12, 2026

Two sizes make up most of Glenwood Springs Storage: 66 drive-up 10x20 units and 37 drive-up 10x25 units. They look similar on paper, five feet apart, but those five feet decide whether a crew-cab pickup closes the door or sticks out of it. Here is what fits in each.

1. The 10x20: a one-car garage

A 10x20 is ten feet wide and twenty feet deep, 200 square feet, about the size of a standard one-car garage. Most sedans, small SUVs and short-bed pickups fit with room to open a door and walk past.

For a household, a 10x20 holds the furniture and boxes from a two to three bedroom home: beds, a sofa, a dining set, appliances and the boxes stacked along the walls. It is also the common choice for a summer car in winter, a snowmobile trailer in summer or a contractor's tools and materials.

2. The 10x25: the extra five feet

A 10x25 is 250 square feet. Those extra five feet are what most full-size trucks need. A crew-cab pickup with a long bed often runs 20 to 21 feet bumper to bumper, which is too long for a 10x20 with the door closed and comfortable in a 10x25.

The 10x25 also takes a boat on its trailer up to about 24 feet from the bow to the tip of the hitch, a side-by-side on its trailer with the gear around it, or a car plus a household of furniture.

3. A quick way to decide

  • Car, small SUV or short-bed pickup: 10x20.
  • Crew-cab long bed or a lifted truck with a hitch: 10x25.
  • Boat or side-by-side on a trailer: measure bumper to hitch. Up to about 19 feet, 10x20. Up to about 24 feet, 10x25.
  • Two to three bedrooms of furniture: 10x20. A household plus a vehicle: 10x25 or 10x30.

Not sure? The Will it fit tool on our size guide draws your vehicle to scale inside each unit.

4. Measure the door, not just the unit

A unit is always a little wider than its door. Measure the widest point of your vehicle with the mirrors out. If it is close, call or text us at (970) 633-3122 before you rent and we will check it for you.

5. What every unit here has in common

Every unit at our facility on County Road 154 is drive-up, with a roll-up door and your own lock, behind a keypad gate. They are enclosed and out of the snow, but not heated or climate controlled. Rentals are month to month.
