You've already decided a metal carport is what you need. The harder part comes next: how wide, how tall, which roof style, and what goes underneath it. Those four calls decide whether your metal carport actually fits the vehicle and holds up in your weather. Here's how to work through each one, and what Panhandle Metals takes care of once your order goes in.

Key Highlights

  1. Widths run from 12 ft for a single vehicle up to 30 ft for a triple, with wider clear-span builds available for commercial use.
  2. Leg height, not width, decides whether an RV or a tractor actually fits. RV covers usually get ordered at 12 to 14 ft.
  3. There are three roof styles: regular, A-frame horizontal, and vertical. Vertical is the one to get if you deal with snow or heavy rain.
  4. Carports anchor to ground, gravel, asphalt, or concrete. Getting the site level and ready is on you, not on the install crew.
  5. Frames are built from 12-gauge and 14-gauge galvanized steel tubing, and wind and snow load certification is an option you pick at order time.

What Size Metal Carport Do You Need?

Sizing comes down to three numbers, always written width x length x leg height. Width covers your vehicle plus room to open a door and walk around it. Length covers the vehicle plus a little overhang at each end. Leg height covers the tallest point of whatever you're parking, plus enough clearance to get it in there without a spotter.

Standard Metal Carport Size Ranges

Carport Type Typical Width Typical Leg Height Best For
Single / one vehicle 12 ft (standard) 6 to 8 ft One car, truck, motorcycle, or ATV
Double / two vehicle 18 to 24 ft 6 to 9 ft Two vehicles side by side; side-entry layouts available
Triple / three vehicle 26 to 30 ft 7 to 10 ft Three vehicles, or two plus equipment
RV / camper cover 12 to 22 ft 12 to 14 ft Class A and Class C RVs, fifth wheels, tall trailers
Boat cover 12 to 20 ft 8 to 12 ft Boats on trailers, pontoons, jet skis
Farm / ranch 20 to 30 ft 10 to 14 ft Tractors, hay, dump trailers, livestock shade
Commercial / clear span 30 ft and up 10 ft and up Fleet parking, equipment yards, covered work areas

These are common configurations, not a stock list. Panhandle Metals offers custom metal carports in configurations for cars, trucks, equipment, and other storage needs.

Why Leg Height Trips People Up

Leg height gets measured at the eave, not at the peak. That one detail costs people money. The peak of a 10 ft A-frame sits higher than 10 ft, but the opening you drive through is 10 ft, and your fifth wheel is 12. Measure the tallest thing on the vehicle, whether that's a roof AC unit, an antenna, or a ladder rack, then add a foot or two so you're not holding your breath every time you pull in.

Before you order, run through this list. Measure the vehicle at its widest, longest, and tallest. Add clearance on all sides. Measure the footprint you actually have available. Make sure a delivery truck can reach the spot. Look up for power lines and tree limbs, and check how close you're allowed to build to your property line. For taller vehicles, metal RV covers can be configured around motorhomes, fifth wheels, campers, and trailers.

Metal Carport Roof Styles Explained

Roof style changes two things that matter. Panel direction decides how rain and snow come off the roof. The framing underneath decides how the structure handles wind.

Regular roof style is the most cost-effective of the three. It's built with corrugated ridges running from one end of the roof to the other, and it does a solid job keeping sun off your vehicles. It suits areas that don't get much wind or rainfall. If you see real snow, this isn't your roof.

A-frame horizontal roof style uses the peaked A-frame shape with horizontal panels. It costs less than vertical because it doesn't need the same fitting pieces. This is the pick for strong winds without much snow or rain. Some of the industry calls it a boxed-eave roof.

Vertical roof style is that same A-frame shape with the panels turned to run down the slope, so snow and water slide off instead of sitting on the seams. Panhandle Metals recommends it for anywhere with regular snowfall or heavy rain, and for any larger building regardless of climate. It costs more up front and asks less of you later.

Factor Regular A-Frame Horizontal Vertical
Panel direction Corrugated, end to end Horizontal Vertical, ridge to eave
Roof shape Rounded A-frame peak A-frame peak
Rain & snow shedding Basic Basic Best — sheds snow and water
Wind performance Limited-wind areas Good in strong wind Best, and recommended on larger builds
Relative cost Lowest Mid Highest up front
Recommended for Sun protection, mild climates High wind, low snow and rain Regular snow or heavy rain; any larger building

Choosing between metal building roof styles comes down to panel direction, weather exposure, building size, and how much rain or snow the structure needs to shed.

Open, Partly Closed, or Fully Enclosed?

A carport doesn't have to stay wide open. Paneling is a standard customization, and there's a ladder of options: leave it fully open, close one or two sides to block the wind you actually get, close the gable ends, add a storage bay, or close it up completely, at which point you've got a garage. Doors, frame outs, and windows are on the options list too.

Closing sides buys you wind protection and security, and it costs more. An enclosed structure is also likelier to need a permit. It's cheaper to spec panels on the original order than to add them later, so if you think you'll want sides eventually, say so up front. If you already know you want it closed in, metal garages give you a fully enclosed option for vehicles, equipment, tools, and storage.

Carport or garage? Think about how much weather protection, security, and enclosed storage you need before choosing the final configuration.

What Goes Under Your Carport

Foundation and ground-level work is the customer's responsibility. The crew shows up to install the building, not to grade your lot. The ground needs to be clean, level, and easy to get to.

  1. Ground: anchors driven into the earth. Standard for carports, small storage buildings, and some agricultural barns. Fastest and cheapest option.
  2. Gravel: common under residential sheds, carports, barns, and garages. Drains better than bare dirt.
  3. Asphalt: stronger than ground or gravel, and the usual pick when the carport is going over an existing driveway.
  4. Concrete: the strongest and most popular option, and the one Panhandle Metals recommends. It holds the building steady through rough weather. The slab has to be poured, cured, and level before install day, so confirm timing with your concrete contractor.

Before the crew arrives, clear and level the ground, leave room for the truck, and mark any electrical wires and water pipes. Call 811 before digging so underground utilities can be located. Proper metal building site preparation helps give the installation crew a clean, level, accessible area for the structure.

Certification and Permits

A certified carport is engineered to meet specific wind and snow load requirements, and it comes with documentation your building department may ask to see. On Panhandle Metals buildings, certification is an option you select when you order. It isn't automatic, and what's available depends on your configuration and where you live. That's one practical upside of buying through a dealer that ships nationwide: the build gets matched to your state's requirements instead of whatever one factory happens to produce.

Permit rules vary by city and county, but the pattern holds up everywhere. Bigger, enclosed, permanently anchored structures draw permit requirements more often than small, open, ground-anchored ones. Call your county building permit office before you order, not after the steel shows up in your driveway. If you need documentation for a certified build, the team can help you sort it out. These common metal building permit mistakes are worth checking before you finalize a building order.

Conclusion

Work the decisions in order and this stays simple. Size around the vehicle first, and pay attention to leg height. Pick the roof style your weather calls for, not the one your budget likes. Then sort out the foundation and how open you want it. None of it locks you in either, since sides can go on later.

Frequently Asked Questions

What is the most common metal carport size?

The 12 ft wide single and the 18 to 20 ft wide two-car carport get ordered most often. A 12 ft single covers one car or truck with walking room on one side. An 18 to 20 ft double fits two standard vehicles side by side without anyone dinging a door. Common metal carport configurations range from single-vehicle covers to wider structures for multiple vehicles and equipment.

How long does metal carport installation take?

A small carport or shed goes up in two to three hours once your site is ready. A standard garage runs about six hours and a standard barn about eight. Larger buildings can take a few days. Delivery typically lands two to six weeks out depending on size and location, with coverage and lead times influenced by building size, configuration, location, and installation scheduling.

How long does a metal carport last?

Decades, assuming galvanized steel framing, proper anchoring, and a level site. Steel doesn't rot, warp, or attract termites, and there's no yearly sealing or repainting to keep up with. Panhandle Metals buildings come with a 20-year rust-through warranty.

What's the difference between 12-gauge and 14-gauge framing?

The lower number is the thicker steel, so 12-gauge tubing is heavier than 14-gauge. Both are galvanized. Heavier framing matters most on wide spans and in areas that get high wind, where there's more load on the frame. Ask about it when you're speccing your building.
