RV Portable Garage Size & Clearance Guide
Choosing the right size portable garage for your RV is critical for proper protection, ease of access, and long-term usability. This guide will help you determine the correct width, length, and height for your RV, camper, or trailer so you can select a shelter that fits comfortably and performs reliably.

Step 1: Measure Your RV Dimensions
Before selecting a portable garage, measure your RV’s full dimensions:
- Total Height: Include rooftop accessories like air conditioners, vents, antennas, and solar panels
- Total Length: Measure from front bumper to rear ladder or spare tire
- Total Width: Include mirrors, awnings, and slide-outs (if extended)
Always use the largest measurement to ensure proper clearance.
Step 2: Recommended Clearance Space
To avoid tight fits and make parking easier, allow extra space beyond your RV dimensions:
- Height Clearance: Add at least 12–24 inches
- Width Clearance: Add 12–24 inches on each side
- Length Clearance: Add 24–48 inches for comfortable entry and exit
More clearance makes it easier to maneuver your RV and reduces the risk of damage.
Step 3: Choose The Right Height (Most Important)
Height is the most critical factor when selecting a portable RV garage. Many RVs are taller than standard vehicle shelters.
- Class B Vans: ~8–10 ft tall
- Class C RVs: ~10–12 ft tall
- Class A Motorhomes: ~12–14+ ft tall
Look for high-peak or tall-frame portable garages designed specifically for oversized vehicles.
Step 4: Width & Length Considerations
Make sure your shelter provides enough room not just for the RV, but for usability:
- Wide openings make parking easier
- Extra length ensures full coverage from front to back
- Additional space allows for storage of gear or accessories
Common Mistakes to Avoid
- Choosing a shelter that matches your RV size exactly with no clearance
- Forgetting to account for rooftop accessories like AC units or antennas
- Not allowing enough space for entry, exit, and maneuvering
