Choosing the right size when purchasing or constructing  a carport is one of the most important decisions to make. 

Carports come in different shapes and sizes, and the size you select depends on several factors such as the type of vehicles you need to shelter, your available space, and your budget. 

Understanding the most popular carport sizes can help you determine the best option for your specific needs. In this article, we will explore the common carport sizes, factors influencing size selection, and other important considerations to help you make an informed decision.

1. Standard Carport Sizes

Carports come in various sizes, but a few standard dimensions are most commonly chosen by homeowners, businesses, and car owners. These standard sizes are based on typical vehicle dimensions and the space needed to park and maneuver vehicles comfortably.

1.1 Single-Car Carports

Single-car carports are designed to shelter just one vehicle. These carports are ideal for homeowners with a single car, motorcycle, or other small vehicle, and they are a great choice for those who do not need extra space for additional vehicles or storage. The typical dimensions for a single-car carport are around 12 feet wide and 20 feet long, which is enough to accommodate one vehicle comfortably.

The width of 12 feet ensures that the car can fit with adequate clearance on either side for easy entry and exit. The length of 20 feet is generally sufficient for most standard vehicles, including sedans, SUVs, and light trucks. However, if you own a longer vehicle, such as a pickup truck with an extended bed or an RV, you may need to consider a larger carport.

1.2 Double-Car Carports

Double-car carports are designed to house two vehicles, making them a popular choice for families with more than one vehicle. These carports typically have dimensions of 18 to 20 feet in width and 20 to 24 feet in length, depending on the specific design and manufacturer. A 20-foot wide carport is standard for two vehicles parked side by side, providing sufficient space for maneuvering and getting in and out of the cars.

A double-car carport offers more flexibility than a single-car carport. It allows for additional storage space or room for larger vehicles such as trucks or SUVs. Some homeowners also use the extra space to store other items like bicycles, tools, or equipment, making double-carports ideal for multi-purpose use.

1.3 Triple-Car Carports

Triple-car carports are less common but still widely popular for larger households or businesses with more than two vehicles to protect. These structures typically measure around 24 to 30 feet in width and 20 to 24 feet in length. With a width of 24 feet, a triple-car carport can comfortably accommodate three vehicles parked side by side.

Triple-car carports are also a good choice for people who own larger vehicles like trucks, vans, or RVs. In addition to providing shelter for vehicles, these larger carports can be used for storage purposes. The extra space allows for additional room for lawn equipment, motorcycles, or bicycles, which can be stored under the protection of the roof.

1.4 Custom Carports

For homeowners with unique needs or unusual vehicle sizes, custom carports are often the best option. Custom carports can be designed to fit any space and vehicle combination, offering flexibility in terms of size, height, and other features. While standard sizes are often sufficient for the average homeowner, custom carports are ideal for individuals who have specific requirements or want a carport that aligns perfectly with their property layout.

Custom carports can range in width from 12 feet to 40 feet or more, and their length can be adapted to fit the number and size of vehicles being stored. Additionally, you can choose custom features such as additional height for RVs or trailers, extra storage areas, or enhanced roof designs to suit your property’s aesthetics.

2. Factors to Consider When Choosing Carport Size

Several factors influence the carport size selection. The most critical consideration is the number and type of vehicles you want to shelter, but other elements can also impact your decision.

2.1 Vehicle Size and Number

The type and number of vehicles you own or plan to store in the carport will largely determine the size you need. A small sedan or compact car typically requires less space than a large truck, SUV, or RV. If you own multiple vehicles or large equipment, you will need a carport that provides adequate room for each item.

For instance, a carport designed for an RV will need to be taller and longer than a typical carport for a sedan. Additionally, larger vehicles like trucks may require extra width and length to fit comfortably inside.

2.2 Available Space

The amount of available space on your property will also impact the size of the carport. If your property has limited space, you may need to opt for a smaller carport or consider installing it in a location that allows for a longer structure. Some properties may have restrictions or challenges such as steep terrain or uneven ground that could limit the size and style of carport you can build.

Before purchasing a carport, carefully measure the available space to determine the largest structure that fits within your property’s boundaries. Ensure that the carport has sufficient clearance from fences, trees, or other obstructions.

2.3 Intended Use

While carports are typically used to shelter vehicles, many people use them for additional purposes such as storing outdoor equipment, tools, bicycles, or even as outdoor recreational spaces. If you plan to store more than just vehicles, consider opting for a larger carport that allows for easy access and storage of multiple items.

Additionally, if you plan to use the carport as a workshop or outdoor entertainment area, you may need additional space or height for your intended activities. In this case, a larger carport with added features such as additional walls or storage areas may be ideal.

2.4 Budget and Costs

Budget is an important consideration when choosing a carport size. Larger carports naturally cost more due to the additional materials, labor, and installation time required. Custom carports, in particular, can be more expensive, as they require tailored designs and more complex construction processes.

To keep costs manageable, consider your immediate and future needs. A smaller carport may suffice if you only need a place to shelter one or two vehicles. However, investing in a larger carport now may save you money in the long run, as it can accommodate more vehicles or offer additional functionality.

2.5 Local Building Codes and Permits

Local building codes and regulations may impose restrictions on carport size, placement, and construction materials. Before starting the construction of your carport, it’s essential to check with your local authorities to understand any zoning laws or building permits that may be required.

Some areas may have restrictions on the size of structures built on residential properties, while others may have specific requirements for materials or design. Failure to comply with local regulations could result in fines or the need to dismantle the carport.

3. Additional Considerations for Carport Design

Apart from size, other features can enhance the functionality and aesthetic appeal of your carport. These features can also impact the overall size and layout.

3.1 Roof Style

Carport roofs come in a variety of styles, including gable, hip, flat, and shed roof designs. The roof style can impact the carport’s size and height. For example, a gable roof design generally requires more height and space than a flat roof. Depending on your climate and design preferences, you may also consider a roof with a higher pitch to allow for snow runoff or rain drainage.

3.2 Wall Options

Some carports have partial or full walls to provide added protection and privacy. Depending on your needs, you may choose to have walls on one or more sides of the carport. Full walls provide added security but may require additional space to accommodate the structure. Consider how walls might impact the overall layout and functionality.

3.3 Flooring and Drainage

While carports typically do not have flooring, some homeowners opt to install concrete or gravel floors to make the space more functional. If your carport is located on uneven ground, you may need to invest in leveling the site or adding drainage solutions to prevent flooding.

Conclusion

Selecting the right carport size is a crucial step in protecting your vehicles and maximizing the functionality of your property. By understanding the most popular carport sizes and considering factors such as vehicle type, available space, intended use, budget, and local regulations, you can choose the perfect carport for your needs. Whether you’re looking for a small, single-car carport or a spacious triple-car design, the right size can help ensure that your carport meets your requirements while offering long-term value.
