Metal Carport Sizes and Dimensions Guide
Metal carport dimensions follow a standard width x length x leg height format. Width runs from 10 feet to 40 feet for standard tubular steel units. Length is effectively unlimited in increments. Leg height starts at 6 feet for standard single-car carports and goes up to 12 feet as a standard option, with taller legs available on request.
Single-car carports (12 to 15 feet wide, 21 feet long) are the most affordable option starting at $1,195. Two-car carports (18 to 22 feet wide) are the most popular category, covering two standard vehicles with room to open doors. Triple-wide carports (24+ feet wide) accommodate three vehicles, trucks, boats or large equipment.
When planning your site, remember that the base rail is 1 foot shorter than the roof length due to 6-inch overhangs on each end. If you need exactly 40 feet of enclosed coverage, order a 41-foot length carport. Contact our team to confirm the right dimensions before ordering.
How Much Does a Metal Carport Cost in 2026?
Metal carport prices in 2026 range from $1,195 for a basic 12x21 single-car carport up to $9,000 or more for a large 30x50 commercial-span structure. All tubular steel carport prices from Steel and Stud include free delivery and professional installation.
Key pricing factors include: Width (wider carports cost more per linear foot), Length (additional bays add proportional cost), Leg Height (taller legs cost more), Roof Style (vertical adds ~15% over regular), and Frame Gauge (12-gauge adds ~12% over 14-gauge but adds a 20-year warranty).
DIY carport kits cost less because installation labor is excluded, but most property owners find the free professional installation included in tubular steel orders to be a significant value. A crew that installs 50 carports per week consistently outperforms a first-time DIY attempt.
Metal Carport Installation: What to Expect
After your order is confirmed and your deposit placed, the manufacturer assigns an installation crew for your region. Current lead times run 4 to 8 weeks depending on your location, structure size and seasonal demand. You will be contacted within 60 days of ordering to schedule your installation date.
Site requirements before the crew arrives: a flat, level surface (within 2-3 inches), clear access for a delivery truck, and any permit posted or available. Concrete pads are preferred but not required for ground or gravel installations. The installation crew typically completes a standard single or two-car carport in 3 to 6 hours. Larger triple-wide or tall-clearance units may require a full day.
Balance payment is made directly to the manufacturer after your carport is installed and you are satisfied with the result. Financing and rent-to-own options are available through Steel and Stud for customers who prefer monthly payments. View financing options or request your free quote to get started today.
