Most RV parking garages use doors between 12 and 14 feet tall, with 12 feet being a typical “safe minimum” and 14 feet preferred if you own (or might upgrade to) a large Class A or Super C.
Typical recommended heights
Guidance from RV and door suppliers typically puts Class A and Super C garage door height in the 12–14 foot range to comfortably clear coaches that are 11–13.5 feet tall plus roof accessories.
How to choose your height
- If you plan only for smaller Class B/B+ rigs or camper vans, a 10- or 12-foot door may be enough, since many of these are 7–10 feet tall.
- For flexibility and property resale, we recommend a 12-foot-tall by 12-foot-wide RV door, with 14 feet of height if you want to future‑proof for any highway‑legal Class A or Super C (max vehicle height is generally 13.5 feet).
Practical rule of thumb:
Measure the tallest point on your current or planned rig (including A/C, satellite, roof racks, etc.), then add at least 1–2 feet of clearance; in practice, this usually gives you a 12–14-foot-tall door for RV use.
Also, be aware that doors for pre-engineered metal buildings must be 2’ below the eave height, so for a 14’ door, you will need to specify a 16’ eave height. Maintaining a minimum clearance of 2 feet between openings and the building’s corners or roofline is critical for structural integrity, code compliance, and weatherproofing.
Note: For buildings with bypass sidewalls, manufacturers often recommend adding an extra 8–10 inches to this minimum distance to account for the depth of bypass girts.
