Garage door dimensions detailed

One of the most common questions our customers ask is: ‘What are the standard garage door dimensions?’ As garage door designs and the average size of homes and vehicles have changed over the years, so too have the standard garage door measurements.

This article will help clarify the standard dimensions for single and double garage doors, so you can decide which size will best suit your requirements.

Standard one door and two door dimensions

Standard one door and two door dimensions

As a general rule of thumb, the standard garage door dimensions are:

  • Single door: 7ft (2,134mm) x 7ft (2,134mm)
  • Double door: 14ft (4,267mm) x 7ft (2,134mm) or 16ft (4,877mm) x 7ft (2,134mm)

As the name suggests, a single garage door provides enough space for one vehicle, and a double door (note: not two single doors) is wide enough to accommodate larger or multiple vehicles.

However, these measurements can be affected by:

  • Building regulations
  • Width of your garage
  • Garage door design

Don’t forget the space needed to open the door

Certain garage doors can take up more space when open than others, meaning a different sized door is needed. For example, up and over garage doors require more depth for when the door is open to allow for extra headroom. To accommodate such restrictions, hiring the expertise of a professional garage door company will ensure the height, width and depth of your garage door is big enough when open.

Check the size of your car

Changes in car design have generally made vehicles wider, taller and longer, which can impact the size of garage door you require. Taking this into account, if you are looking to replace your current door, accurate measurements of your vehicle’s size must be taken to ensure it fits properly.

If you have two cars that you plan on storing in a double garage, make sure you have enough room for both so you have no trouble fitting everything in.

Vehicles for single garage doors

Knowing what size vehicle is best for residential garage doors is relative to each and every garage, as there are a variety of sizes available.

Typically, the standard height and width of a single garage door is seven or eight feet, making it perfectly suited for one of the following vehicles:

  • Car
  • Van
  • SUV
  • Small truck

If your vehicle is larger than those listed above or your household has more than one vehicle to store, you should consider getting a bigger garage door.

Vehicles for double garage doors

As the name suggests, double garage doors are ideal for instances where extra space is required. It accommodates for:

  • Larger vehicles
  • Households with multiple vehicles

It’s worth noting that more room is required for RVs to fit through, so you must keep in mind that the specifications will need to be 16’ wide by 8’ tall garage door and 9’ ceiling.

Garage doors for bigger vehicles

The versatility of sectional garage doors means they can be fitted to almost any size or shape of garage, making it perfect for larger cars which require more space. Available in a selection of styles and materials, the sectional door glides up effortlessly to be stored in the garage roof on horizontal tracks. That way, no additional space is taken up by the door, leaving plenty of room for your vehicle.
