Mobile Office Trailer Sizes
Start with enclosed floor space rather than the number in a trailer listing. A 60-foot advertised office may have a 56-foot building box with the hitch included in the overall length; another supplier may use 60 feet for the building itself. That is why a 12 × 60 class can be described as 672 or 720 square feet. Compare portable office rental prices for the size and rental period you need.
| Common size class | Approximate enclosed area | Typical buying choice |
|---|---|---|
| 8 × 20 ft | Up to about 160 sq ft when these are box dimensions | Compact supervisor office or reception point |
| 10 × 40 ft | Up to about 400 sq ft | Small field team with desks and plan storage |
| 12 × 44 / 12 × 48 ft | Often around 528 sq ft; naming varies | Separate offices plus shared work space |
| 12 × 60 ft | Commonly 672–720 sq ft, depending on length convention | Project team, private offices and meeting space |
| 24 × 60 ft double-wide | Commonly 1,344–1,440 sq ft | Larger team with several rooms and a meeting area |
These are advertised size classes, not identical supplier specifications. Some lengths include the hitch. Confirm the enclosed box dimensions, usable interior area and actual floor plan.

An open layout makes it easier to position desks and use a central plan table. Separate offices give project managers somewhere to take calls or meet privately, but partitions and doors consume floor area. A useful plan should show doors, windows, room dimensions and the location of heating and cooling equipment—not just an external rectangle.
When choosing temporary office space, list the workstations used at the same time, then add the meeting table, printer, drawing storage and circulation you need. A rough office-planning allowance of 100–150 square feet per regular user can help start a discussion, but it is not an occupancy approval and may not fit a room-heavy plan.
Single-Wide vs Double-Wide Mobile Offices
A single-wide arrives as one transportable building. It is a useful starting point for a supervisor office or a smaller project team. A double-wide arrives in sections joined on site, allowing wider shared areas and more separate rooms. The extra usable space brings additional delivery and installation work, so compare the full cost rather than doubling a single-wide rate.
For a larger connected office complex, compare modular building options as well. Choose between them using the floor plan, site and expected period of use. Then compare the rental and installation prices for the same specification. Get mobile office rental and purchase prices to put the available options side by side.
| Office choice | Useful advantage | Check before ordering |
|---|---|---|
| Compact single-wide | Smaller footprint | Desk and meeting space; entry equipment |
| Large single-wide | Private rooms and shared work area | Box length, restroom space and room dimensions |
| Double-wide | More rooms and wider meeting space | Joined floor plan and full freight/setup scope |
Office Trailers with Restrooms, HVAC & Furniture
A restroom is useful when separate facilities would be inconvenient, but it takes space away from offices and requires a water-and-waste arrangement. A unit without plumbing can leave more room for desks or meetings. Ask to see both versions if the floor area is tight.
Confirm the actual HVAC equipment, power requirement, desks, chairs, security features, steps and ramps supplied with your unit. Do not assume an accessible restroom makes the whole installation accessible: the route to the entrance and the installed entry arrangement matter too. Ask the provider to identify the relevant configuration before you commit. Our mobile office FAQs cover common questions about equipment and included costs.
