What dimensions for a carport?
Dimensions of a carport
Would you like to install a carport outside to store your car or even your motor home? However, choosing the right dimensions isn't always easy, and depends on a number of factors: the space available, the vehicles, the neighbourhood... You'll find the answers to your questions here.
What you need to know
When you're planning a carport, it's vital to think about the size to choose. It's a project that will last a lifetime and take up a lot of space. It's best not to get the dimensions wrong. When making your choice, we advise you to think about the present as well as the future. If you need to house just one car today, that may not be the case tomorrow. You can also change your car and buy a bigger one. So plan your carport according to your future plans and a few other criteria:
- Carport dimensions are proportional to vehicle volumes.
- Allow a metre of space around the vehicle, to make it easier to open the doors, or even manoeuvre. This large space will allow you to store an extra two-wheeler, garden furniture, etc.
- Space in front of and behind the car is essential
- Remember that to install a carport, you need a flat, preferably concrete surface. It must be at least the same size as the carport's footprint.

Dimensions of a carport for a car or motor home
Lean-to carports or island carports generally have the following dimensions:
- Between 12 and 15m2
- Between 2.5 and 3 metres wide
- Approximately 5 metres long
There are two different types of motorhome. Class two motorhomes, with a height of between 2.5 and 3 metres and a maximum weight of 3.5 tonnes, and class three motorhomes, with a height of over 3 metres and a weight of over 3.5 tonnes. We advise you to refer to the dimensions of your motorhome, while applying the necessary space criteria.
Akena flat roof carports are up to W8 x D5 x H3.2 metres. Made to measure, they are ideal for all types of vehicle.

Carport for two cars or motorhome
For two cars, in proportion to the dimensions given for one car, please double the values, i.e. :
- Between 24 and 35 m2
- Between 5 and 6 metres wide
- Approximately 10 metres long
The same applies to two motor homes.

A double carport is the ideal solution for a functional shelter when you have several vehicles. As well as adding an aesthetic touch to your garden, it protects your possessions and enhances the value of your property. But to get the best possible structure, it's essential to choose the right dimensions. AKENA gives you all the advice you need to choose the right size for your 2-car carport!
What size carport for 2 cars? Things to remember
- The standard size of a double carport is 7 metres wide and around 7.2 metres long if the cars are parked side by side.
- The width is around 4 metres if the cars are parked in a row.
- The height depends directly on the type of vehicle (city cars, vans, SUVs, camper vans, etc.).
- Carports can be up to 15 metres long.
- The ideal size depends on the layout of the cars and their characteristics.
- It's best to work with a professional like AKENA to determine the right size of carport for 2 cars.

How do you determine the size of your double carport?
Choosing the right size for your 2-car carport is essential to optimising your outdoor space, and protecting your vehicles from the elements effectively.
What you need to know is that the perfect size for a two-car carport is not universal. It depends on a number of factors
- the size of your vehicles
- the way they are parked
- the type of roof the carport has;
- the amount of space you need to move around.
All these factors have an impact on the surface area and height of your future parking space.
What is the ideal height for a two-car carport?
To determine the right space between the floor and ceiling of your car structure, it is essential to take into account :
- The type of vehicle parked: for city cars and saloons, a height of 2.20 m is generally sufficient. An SUV or 4x4 will need to be at least 2.40 m high. Finally, for motor homes, the height can vary between 2.5 m and 4 m.
- Roof pitch: for flat-roofed carports, the minimum height is calculated according to the height of the vehicle. However, with a pitched roof, it's essential to take account of rainwater run-off.
You should also be careful not to choose too high an entrance height for your carport! A carport that is too high in relation to your vehicles can let in rain and snow, compromising their protection.

How wide do I need to park two vehicles?
In terms of width, the dimensions of a carport can vary depending on the type and layout of the cars (parked side by side or one behind the other). It's important to leave enough space between the vehicles and the walls to facilitate manoeuvring, passage between cars and door openings.
In most cases, the width of a carport for two cars is :
- Side-by-side parking: between 5 and 8 metres.
- Stacked parking: around 4 metres.
Note also that carports built against a house are also wider, to maximise the comfort of the owners!
What size should a double carport be?
The length of a carport for 2 cars again depends on how you park your car, and what you want to protect!
To have enough space for two city cars or two SUVs, a standard carport will be between 7 and 8 metres long. Large carports, often used for motorhomes, can even be up to 15 metres long!
Our advice for optimum space
To ensure that you have enough space in your double carport, it's important to follow a few tips that will help you maximise the use of your shelter while guaranteeing safety and comfort:
- Assess your current and future needs: think not only about what you own today, but also about what you might acquire in the future.
- Take into account the size of your cars: mark out the perimeters of your vehicles on the ground, and carry out a test to gauge whether manoeuvring is easy and access simple.
- Make sure there's enough room to move around: you need to be able to open the doors easily, take shopping out of the boot, and move around the cars comfortably.
- Consider the multiple uses: a carport can be used for much more than just parking your cars! You could consider creating an area for DIY, storing your gardening tools, or even a place for hobbies.
- Add space for storage and equipment: take advantage of the vertical space by installing shelves, cupboards or hooks. This will help keep the area organised, and maximise the use of the whole double carport.
- Respect local regulations in terms of dimensions: before you start building, check the regulations with your local council or homeowners' association. This will help you avoid legal complications.
- Choose flexible, hard-wearing materials : aluminium, for example, which we prefer at AKENA, is particularly well suited to custom carport designs.
- And don't forget the various customisable options: the equipment and customisation features can also influence the dimensions you need!
In all cases, we advise you to get professional help to define the exact size of your 2-car carport. Contact AKENA, specialists in outdoor structures: our experts will be able to guide you to ensure that your made-to-measure carport perfectly matches your needs!
How much space is required for a 2-car carport?
The surface area required for a car arbi designed to house two vehicles depends on a number of factors. First of all, the dimensions of your cars are decisive. A compact saloon car will not take up the same amount of space as an SUV or MPV. What's more, the way you want to park your cars- side by side or in a row - will also influence the surface area required.
As a general rule, for side-by-side parking, a width of 5 to 6 metres is recommended. For stacked parking, a length of 10 to 12 metres is recommended. To ensure optimum comfort, it is important to add extra space for opening doors and moving around vehicles. The height depends directly on the type of vehicle (city cars, vans, SUVs, camper vans, etc.).
