Common Metal Carport Sizes

The right carport size ensures maximum protection for your vehicles, equipment, and other valuables. So, how do you go about choosing the right carport dimensions? It helps to start by understanding more about common metal carport size categories. Here are some of the popular carport size categories we offer at Carport Central:

  • Single Carport Size (12′ wide Carports – Standard)
  • Double Carport Size (18′ to 24′ wide Carports – Two Car Carports)
  • 3 Car Carport Dimensions (26′ wide to 30′ wide Carports – Triple Carports )
  • Extra Wide or Commercial Carports (32′ wide to 60′ wide Carports )

Of course, we can do more than just point you to the right building size category. The options we provide with custom metal carports set us apart from other metal building companies which only offer basic, “cookie-cutter” designs. We can build and install your custom carport to any specific size dimensions you may need.

Vehicle Measurement Guide for Carports

In order to get an accurate assessment of what size carport and how much carport space you need, it’s best to take a measurement of the width, length, and height dimensions of each vehicle you plan to shelter. The average car length is around 15 feet, average car width is around 6 feet, and average car height typically ranges anywhere between 4 and 6 feet. That being said, average numbers don’t necessarily describe your particular vehicle.

Thankfully, measuring your vehicle is simple to do, and can be accomplished with nothing more than a tape measure and a partner to help you hold the tape.

  • To measure vehicle width: Don’t just measure width in the front or rear. Side-view mirrors typically extend out further, and you definitely want to allow for proper mirror clearance when parking your vehicle. Measure between the outer edges of the two mirrors in order to come up with an accurate width number. The simplest approach might be to put your windows down, and just stretch the tape through the vehicle’s interior.
  • To measure vehicle length: This one is pretty straightforward. Just extend the tape alongside the car from front to rear, and measure from the furthest points. Be sure to include any extended spoilers, truck hitches, etc. in your length measurement as well.
  • To measure vehicle height: Height is also easy to measure. Simply place the end of the tape on the ground beside the car, and then extend the tape up to the tallest point on your vehicle. Don’t forget to include features that extend above the roof, like antennas, mounted racks, etc.

Things to Consider When Sizing Your Carport

There are several factors you should keep in mind when determining the size of the carport you need to have installed at your place of residence or business. Consider the following:

  • The type of vehicle or vehicles: The type of vehicle or vehicles you want to cover should help determine the dimensions of the carport you need. A one-car carport can effectively accommodate a regular car or a small truck. However, if a typical one-car carport doesn’t provide enough space for you to maneuver, consider installing a wider carport. And if you own large vehicles such as heavy-duty trucks, RVs, and trailers, you should consider a double carport or even a triple carport for effective accommodations.
  • The number of cars or trucks: Another issue which impacts carport size is how many vehicles you need to cover. If you intend to house more than one car or truck, then you’ll obviously need a bigger carport. Keep in mind how much space you need between vehicles, too. Ideally, you’ll want to be able to open your doors without having to worry about hitting or touching another vehicle.
  • The height of your vehicle(s): Vehicle height is another aspect which helps determine necessary carport size. You want to make sure you have enough clearance for your tallest vehicle! Standard carports start at 7 feet or 8 feet tall, and this works fine for most regular-sized vehicles. However, if you own a large vehicle such as a truck or an RV with a taller profile, you can build your metal carport taller, too. This is the best way to prevent any height clearance problems when it comes to parking your vehicles under cover.
  • Intended use of your carport: How do you want to use your steel carport exactly? That’s a consideration for planning carport size, too. If you need to accommodate things like farm equipment, boats, or other items, you should choose a proper metal carport design and size to match. At Carport Central, we offer everything from metal farm storage buildings, to boat carports, to RV covers, to utility carports, to any manner of custom carport. We also provide plenty of customization options to meet your needs and preferences.
  • Future considerations: Making plans to increase the size of your fleet or upgrading to a larger car model? Then it’s best to go ahead and build your carport with these considerations in mind. Going with a larger carport size now can save you from having to add on a second carport expansion later.

Why You Should Buy a Metal Carport?

Most people buy a carport to protect their vehicles, but that’s not all our custom-built metal carports are good for! A properly sized metal carport can double as a covered picnic area or outdoor workshop, and can be used for many other things as well. The possibilities really are endless. And beyond the many usage possibilities, there are many benefits from choosing a sturdy metal carport in particular.

Here’s why investing in a carport or metal building from Carport Central makes good sense:

  • Weather: Parking your vehicle under a metal carport or garage is one of the smartest decisions you can make. This will protect your car from harsh weather elements like heavy rain, snow, sleet, hail, wind, and sun exposure.
  • Extra Security: A metal carport – especially one with closed sides and ends – will help keep your valuables out of sight from criminals. It also offers extra security for whenever you’re getting in and out of your car at night.
  • Storage: Of course, prefab metal carports are great for storage, too. You can even add a small shed or building to the structure to turn it into a utility carport that will provide both vehicle coverage and enclosed storage space.
  • Versatility: They’re called carports, but they can really be used to cover any type of vehicle. Besides just cars or trucks, you can use a metal carport to protect RVs, campers, motorcycles, ATVs, boats, lawn equipment, and more.
  • Durability: It doesn’t get any stronger than steel. Our metal carports are designed to withstand the toughest weather conditions. And it gets even better! Our steel structures won’t corrode, you won’t have to worry about termites, and they’re much more fire-resistant, too.
