How to Choose the Right Metal Carport for Your Needs

With so many sizes, styles, and options, picking the right carport can feel overwhelming. This guide breaks down exactly how to match a carport to your needs.

Start with What You're Protecting

The first and most important question is: what will your carport shelter? The answer determines nearly every decision that follows — size, height, length, and whether you need additional features like side panels or enclosed ends. A carport protecting a sedan has very different requirements than one covering an RV, boat, or farm equipment.

Single-Wide Carports (12' to 14' Wide)

Single-wide carports are the most compact and affordable option. At 12 to 14 feet wide, they provide overhead protection for one standard vehicle, a small boat, or outdoor equipment. They're popular for residential use where space or budget is limited.

  • Best for: 1 car, small truck, ATV, riding mower, or utility trailer
  • Typical dimensions: 12'W x 21'L x 6-7'H
  • Starting price range: Under $2,000 in many areas
  • Can be upgraded with side panels or gable ends for extra protection

Double-Wide Carports (18' to 24' Wide)

Double-wide carports are the most popular size category. They accommodate two vehicles side by side, or one vehicle plus workspace, storage, or equipment. The extra width also makes them more versatile — many customers later enclose them into full garages.

  • Best for: 2 cars, truck + trailer, workshop space, or enclosed garage conversion
  • 18' wide fits 2 compact cars; 22' fits 2 full-size vehicles comfortably
  • 24' wide provides generous room for 2 large trucks with door-opening clearance
  • Most popular configuration for residential properties

Triple-Wide Carports (26' to 30'+ Wide)

Triple-wide carports provide maximum coverage for multiple vehicles, large equipment, or combined parking and workspace. At 30 feet wide and beyond, these structures rival small commercial buildings in their utility.

  • Best for: 3+ vehicles, RV + car, farm equipment, or large covered workspace
  • 30' wide is the most popular triple-wide size
  • Often used for commercial parking, equipment storage, or event shelters
  • Can be enclosed into large workshops or multi-bay garages

Height Considerations

Side height is measured at the wall, not the peak. Standard carports start at 6 feet, but we recommend thinking ahead. If you might ever enclose your carport into a garage, you'll need enough height for a garage door (standard residential doors are 7 or 8 feet tall, plus a few inches of clearance). For RVs, 5th wheels, and large trucks, measure your tallest vehicle and add at least 2 feet of clearance.

Length: Don't Forget to Add Buffer

A common mistake is ordering a carport that's exactly the length of your vehicle. Always add at least 5 feet to your vehicle's length for comfortable entry and exit. Standard lengths are 21', 26', 31', 36', and longer in 5-foot increments. For RVs and boats, measure carefully — a 36-foot motorhome needs at least a 41-foot carport.

Open vs. Partially Enclosed vs. Fully Enclosed

Carports offer a spectrum of enclosure options. A fully open carport provides basic overhead rain and sun protection at the lowest cost. Adding side panels on one or two sides blocks wind-driven rain and provides privacy. Enclosed ends with gables or full panels add structural rigidity and weather protection. A fully enclosed carport with garage doors essentially becomes a metal garage — giving you complete security and weather protection while starting from a carport's efficient design.
