The first thing you need to decide when building a metal carport is how the carport will be used. Consider how much space you'll need to adequately protect your belongings from the elements and be sure to think about the future if you plan to acquire any additional vehicles that may need storage.
Select the Perfect Width When Building a Metal Carport:
Carport sizes vary by the width and range from single carports to triple carports. Generally, single car carports provide enough room for one car, double carports hold two cars and triple carports can accommodate three cars.
Of course, you may want to use your metal carport for something other than storing a vehicle. If this is the case, you'll want to add the total number of feet that you want to cover in order to find the right carport size for your needs.
