Parking Lot Angle Guide

Parking lots can have cars placed at 30, 45, 60, 75, and 90° angles. The following is our guide on which is best for your parking lot.

There’s a surprising amount of forethought that goes into parking lots. They need to be ADA (Americans with Disabilities Act) compliant. They need to have visible and maintained painting/striping. Signage and lighting need to be absolutely clear and visible as well. Additionally, they need to take into considerations things like how fast people will be going, how many pedestrians there will be, and much more. One thing many business owners forget is that the parking lot is the first thing most customers see when they come to that business. It sets the tone for what the interaction will be like. A rutted, damaged lot will immediately put people off and make them more on-edge than a well-maintained visually appealing parking lot. You should keep your lot looking its best, because it leaves a good impression on people.

This guide is about what angle your parking spaces should be at. Parking angle may seem like a minor detail, something that only paving professionals and city planners care about, but it makes a difference.

What does parking angle affect?

Parking angle makes a big difference on a few aspects of your lot.

  • How many cars can you fit in an area? This determines how many cars can fit either in a parking lot or on a street.
  • Are parts of the parking lot one-way? This will be really important depending on the parking angle….in fact, one-way might be the only option with certain parking angles.
  • How much room do you need to leave for other cars to get by? If there is two-way traffic between the parked cars, then you need at least two lanes worth of space. If there is one-way traffic only, you can get by with less space.
  • How much space do you want to give pedestrians/non-motorists? People need to leave their cars eventually and go home or into your business. Parking angle and the lot design in general will affect their experience doing this.
  • What about safety? Parking angle effects how people are backing out of spaces, either into traffic or into the parking lot.
  • Is holding up traffic an issue? If traffic around your business shouldn’t be slowed down, this also affects what parking angle is best.

Important Stats

When we talk about parking lot angles, we will also throw a few numbers in.

  • Stall width/length- This is how wide/long the area the car will park in is.
  • Row- this is a row of spaces together. Its area is a function of the stall width, length, and angle.
  • Aisle- this is the area nearby the parking space for cars to drive in when they enter and exit the space.
  • Single/double rows and aisles- single/double refers to one-way or two-way vehicle traffic.

Of course, there are plenty more stats about each angle of parking space, but we figure this should be enough for a basic guide to the various angles.

For each of our parking stalls, we are assuming the following:

Stall Width: 9 feet.

Stall Length: 18 feet.

The aisle width will vary with each angle.

30° Angle

This is the tightest parking angle that most lots use. It’s often used because it provides better maneuverability and reduces delays of cars getting into and out of the spot. The tight angle to the road simply allows for easier access. Of course, the trade-off is fewer cars can fit in the lot total.

Aisle width: 12 feet.


45° Angle

This is one of the most common angles you will see in lots. It’s often in grocery stores, malls, and anywhere where a lot of cars are parking and moving. It can accommodate more vehicles than a 30° spot and thus is better for high-concentration areas. 45° is a great balance of fitting the maximum parked cars in a space while keeping things moving and ensuring that there aren’t major bottlenecks.

Aisle width: 13 feet.

60° Angle

60° Is usually the middle ground between 45° spaces and 90° spaces. It packs more cars in than lower angles, at the expense of requiring more space in the aisle and taking more time for cars to get in and back out. Because vehicles are at 60°, they still can get into and out of spaces with relative ease.

Aisle width: 16 feet.


75° Angle

Much like the 60° angle, this angle choice is for businesses who want cars to have an easier time getting in, but want to balance that with higher lot capacity. The trade off is that more space is needed for the aisle because more turning radius is also needed for the cars at a wider angle.

Aisle Width: 20 feet.

90° Angle

One of the most common angles, this is the best for maxing out how many cars can fit in a parking lot. There is no space lost at the beginning or end of a row due to the angle. Of course, the major trade-off is that a flat 90° angle is much slower to get in and out of. This means traffic in the lot will be slower, and pedestrians will have to be more careful when walking through the aisles. 90° Stalls also require the largest Aisle Width.

Aisle Width: 24 feet.
