UK Car Size Trends & Parking

It's a question many drivers ponder, especially when squeezing into a tight spot or eyeing up a new vehicle: just how big are cars in the UK, and how does this affect where we can park them? The automotive landscape has certainly shifted over the decades, with vehicles generally growing in both length and width. This evolution has a direct impact on the design and functionality of parking spaces, a crucial consideration for both individual car owners and larger development projects. Understanding these changes is key to ensuring our parking infrastructure remains practical and safe for everyone.

The Growing Footprint: How Cars Have Changed

The average size of a car on UK roads has seen a noticeable increase over the years. Research indicates a significant trend: cars sold today are substantially larger than their predecessors from the mid-20th century. To illustrate this point, let's look at the data:

In 1965, the top five most popular car models in the UK boasted an average width of approximately 1.5 metres and an average length of around 3.9 metres. Fast forward to 2020, and the picture is quite different. The top sellers from that year had an average width of 1.8 metres and an average length of 4.3 metres. This means that, on average, cars are now 0.3 metres wider and 0.4 metres longer than they were just over fifty years ago. This expansion is a crucial factor for urban planning and parking provision.

Recommended Parking Space Dimensions in the UK

To accommodate these growing vehicle dimensions and ensure safe and efficient use of parking areas, specific minimum dimensions are recommended for private developments. These guidelines aim to strike a balance between maximising the number of parking spaces and providing adequate room for vehicles to be parked and accessed safely.

Standard Parking Spaces

The standard parking bay has remained a consistent size for a considerable period. However, the increasing average size of cars necessitates that these standards are reviewed. The recommended minimum dimensions for a standard parking space are:

Parallel Parking Spaces

For situations where parallel parking is the preferred layout, such as on many residential streets, the recommended minimum dimensions are slightly different to account for the linear nature of the parking:

Disabled Parking Bays

Accessibility is paramount, and disabled parking bays are designed to offer more space for wheelchair users and easier entry and exit for those with mobility challenges. The recommended minimum dimensions are:

Parking Spaces with EV Chargers

The rise of electric vehicles (EVs) brings new considerations. Parking spaces equipped with EV chargers often require slightly more width to accommodate the charging equipment and the vehicle's charging port. The recommended minimum dimensions are:

It's important to note that parking spaces for EV charging must also adhere to the minimum space requirements set out in Building Regulations Part S, which can vary depending on whether the charging point is freestanding or wall-mounted.

Garages (Internal Sizes)

For private garages, the internal dimensions are crucial for determining if a car can actually fit and be used effectively. The recommended minimum internal sizes are:

Additional Space Considerations

Beyond the basic bay dimensions, several factors can necessitate additional space:

• Obstructions: Where any dimension of a parking space is adjacent to a wall or another obstruction, an additional minimum of 0.5 metres should be added. This extra room is vital for safe opening of car doors and manoeuvring.
• Access and Storage: If parking areas are also used for safe and convenient access to the rear of a property, such as for cycle storage, more space may be required.
• Driveways for Garage Access: When driveways are intended for parking in front of a garage, the overall length of the space needs to be a minimum of 6.0 metres to allow adequate access to the garage itself.

The Garage Dilemma: Storage vs. Parking

It's a common observation that many single on-plot garages are often used for storage rather than housing vehicles. Given the extent of this practice, whether a garage can be counted towards a development's parking provision is determined on a case-by-case basis, following guidance from publications like 'Manual for Streets'. If a garage is accepted for parking and also relied upon for cycle parking, its overall size will need to be increased beyond the standard recommendations to accommodate both.

Tandem and Side-by-Side Parking

Tandem parking, where one vehicle is parked behind another, is generally acceptable for individual properties. However, it's not typically suitable for properties intended for use by more than one dwelling. For driveways longer than 6 metres, they will be counted as a single parking space unless the developer can convincingly demonstrate that the driveway can reasonably accommodate more than one vehicle and still allow access to any provided garages.

When planning for side-by-side parking on a driveway, additional width is necessary, particularly if the driveway also serves as pedestrian access to the rear of a property. This ensures that both vehicles can be parked and accessed safely without impeding pedestrian movement.

Circulation and Manoeuvring Space

Crucially, the overall site layout of a development must consider the necessary circulation and manoeuvring space required to access all the different types of parking spaces described. This includes ensuring that drivers can safely navigate into and out of parking bays, especially in tighter layouts or when dealing with larger vehicles. Different parking layouts, such as parallel parking or herringbone configurations, will naturally have different overall space requirements. Detailed planning of parking spaces using these approaches will always be considered on a site-specific basis to optimise usability and safety.

Frequently Asked Questions

Q1: How much wider is the average UK car now compared to the 1960s?

The average width of the top five car models sold in the UK has increased by approximately 0.3 metres (from 1.5m in 1965 to 1.8m in 2020).

Q2: What is the minimum recommended width for a standard parking space in the UK?

The minimum recommended width for a standard parking space is 2.5 metres.

Q3: Do I need extra space if my parking bay is next to a wall?

Yes, an additional minimum of 0.5 metres is recommended if either dimension of the parking space is adjacent to a wall or other obstruction.

Q4: Are garages always counted as parking provision?

Not necessarily. Whether garages are counted towards parking provision is determined on a case-by-case basis, especially considering they are often used for storage.

Q5: What are the dimensions for a disabled parking bay?

The recommended minimum dimensions for a disabled parking bay are 3.6 metres by 5.0 metres.
