3-Car Carports for Sale: Triple Wide Carports

If you need to protect vehicles, trailers, or equipment, a triple-wide carport offers extra space and flexibility. These metal carports are typically 26 to 30 feet wide — often called a “30-foot carport” — giving you room to park three vehicles side by side or create more space around two for easier access.
Compared to a standard one-car carport, a triple-wide model provides broader coverage for cars, boats, tractors, and other equipment. You can also customize the style, color, and add-ons to fit your needs.

What “Triple-Wide” Means and Popular Sizes
“Triple-wide” is mainly a width category. In most cases, it means a carport that is 26-30 feet wide, which is why many people search for a 30-foot carport when what they really need is a triple-wide layout.
From there, you choose the length and height based on what you’re parking under it and how much room you want around your vehicles or equipment.
These are a few popular sizes customers often start with:
- 30×21
- 30×26
- 30×31
- 28×20
- 26×20
- 30×40


Looking at total square feet can make sizing easier. For example, a 30×26 carport covers 780 sq ft., which usually works for three vehicles with some extra space. If you’re sheltering a trailer or boat, longer lengths such as 30×40 are better to accommodate larger boats and trailers.
For an RV carport or RV covers, height matters as much as width. Many buyers choose a taller leg height as an upgrade so that larger vehicles fit comfortably.
Triple-Wide vs. Double Carports
A standard double carport is often around 18 to 24 feet wide, which works well for two cars parked side by side. A triple-wide option usually falls in the 26 to 30 foot range, giving you the extra width for a third vehicle or more space around two vehicles.
That extra room can make a big difference in day-to-day use. It gives you more door swing clearance, more room to walk between vehicles, and a layout that’s easier to use for tractors, trailers, or equipment that needs a wider turning angle. If you’re shopping for three-car carports, it can also help if you want to keep one bay open for storage without squeezing everything together.
If you’re deciding between a wide two-car style carport and a three-car layout, think about how you’ll use the space most days. Regardless of which type of carport you choose, a high-quality steel carport with a solid steel frame can work either way. It mainly comes down to width and clearance.

Roof Styles, Framing, and Layout Options
Each roof style changes the look of the carport, and it can also affect how the roof handles leaves, rain, and snow in your area.

Optional layout upgrades: Add side panels, choose a side entry layout, partially enclose one or more sides, or add a lean-to for covered storage. If you need full enclosure with garage doors, a metal garage or steel building may be a better fit than a standard metal building carport (including a vertical roof garage setup). Use our 3D carport and garage builder to compare roof styles, colors, and trim.
Structural Support, Wind, Snow Load, and Building Codes
Triple-wide builds cover more space, so it’s worth thinking through the basics before you settle on a final design. Here are a few practical things to look out for:
Support needs
Wider spans may require reinforced braces, additional legs, or adjusted spacing depending on your layout and site conditions.
Frame and materials
Choose the steel frame and gauge options that make sense for your region and how you plan to use the carport.
Wind ratings
Wind ratings are listed in mph (miles per hour). Some configurations may reach up to 140 mph, but ratings vary by design.
Snow ratings
Roof strength is measured in psf (pounds per square foot). Certain builds may support around 35 psf depending on configuration.
Local requirements
Building codes and permit rules vary by location, so confirm local requirements before placing your order.

Frequently Asked Questions
Most three-car layouts work best between 26 and 30 feet wide. The exact width depends on vehicle size, how far doors need to swing open, and whether you drive larger trucks or SUVs. If you want more walking space or storage along the sides, leaning closer to 30 feet can help.
It depends on material costs, local labor rates, building codes, and site prep. Buying a prefabricated metal carport or steel carport can simplify the process because the main structure is already engineered, but you’ll still want to compare quotes for concrete, permits, and any electrical work.
Triple-wide pricing starts around $2,695 for a basic 30×20 configuration, then changes as you adjust width, length, height, roof style, and enclosure options. The easiest way to see how each choice affects the total is to build a few layouts in the 3D tool and compare them side by side.
A triple carport is typically 26 to 30 feet wide, which is why many people search for a 30-foot-wide metal carport when they mean “triple-wide.” That width is usually enough for three standard vehicles parked side by side, with some flexibility for local preferences and vehicle sizes.
