In this article, we’ll guide you through the standard door sizes in the UK, how to choose the right size door for your home, and other factors to consider when selecting a door. So, whether you’re renovating your existing home and need a replacement internal door, or you’re building a new one and need fire doors to meet fire safety regulations, keep reading to learn more about UK standard door sizes and what to consider when selecting the right one for your needs.

Door dimensions: which measurements are important?

When it comes to selecting a door size, you need to make note of several key measurements. These measurements include the door width, height, and thickness.

Let’s take a closer look at each of these measurements and explain why each one is so important. (We’ve included both imperial (feet, inches) and metric door sizes):

  • Door Width: The width of the door is the measurement from side to side. The width of the door can affect the amount of space needed for the door to swing open and close, as well as the ease of moving furniture and other large items through the doorway. The standard door width in the UK is 762mm (30 inches). However, there are other widths available, such as 686mm (27 inches) and 838mm (33 inches).
  • Door Height: The height of the door is the measurement from top to bottom. The height of the door is essential to consider, as it can affect the amount of headroom available in the room, particularly if the door is located in a low-ceilinged area. The standard internal door height in the UK is 1981mm (6 feet 6 inches). However, other heights are available, such as 2040mm (6 feet 8 inches) and 2135mm (7 feet).
  • Door Thickness: The thickness of the door is the measurement of the door from front to back. The thickness of the door can affect the overall strength and durability of the door, as well as its ability to provide insulation and soundproofing. The standard thickness for a door in the UK is 35mm (1 3/8 inches). However, other thicknesses are available, such as 40mm (1 5/8 inches) and 44mm (1 3/4 inches). Bear in mind that a fire door will need to be thicker than a standard internal door – an extra 4mm will help keep smoke and flames at bay for a minimum of 30 minutes.

Standard UK door sizes (in England and Wales)

Standard internal door sizes

Common door sizes in the UK for internal doors are usually:

  • 1981mm x 762mm (6ft 6” x 2ft 6”). This size is perfect for most rooms, including bedrooms, bathrooms, and closets. It’s also a popular choice for door replacements, as it’s a standard size that is widely available.
  • 1981mm x 838mm (6ft 6” x 2ft 9”). For wider entrances or to create a more spacious feel, this slightly wider size provides an extra 3 inches of width, making it easier to move larger items in and out of a room.

When selecting the right size for your interior doors, consider the size of the room, the function of the door, and any special requirements you may have, such as accommodating wheelchair access or accommodating for furniture. With the right size and style, your interior doors can enhance both the functionality and aesthetics of your home.

Standard external door sizes

The standard door sizes in the UK for external doors are usually:

  • 1981mm x 838mm (6ft 6” x 2ft 9”). This size is perfect for most standard doorways, including front doors and back doors. It’s also a popular choice for external door replacements, as it’s a standard size that is widely available.
  • 2032mm x 813mm (6ft 8” x 2ft 8”). For wider entrances, such as a double door or patio doors, this larger size makes it easier to move furniture, large appliances or other bulky items in and out of the house.
  • 2032mm x 864mm (6ft 8” x 2ft 10”)

When selecting the right size for your exterior doors, consider the size and layout of the entrance, the style of your home, and any special requirements you may have, such as energy efficiency or security features. With the right size and style, your exterior doors can enhance both the curb appeal and functionality of your home.

In addition to these standard sizes, Window & Doors UK offers a range of customisable door sizes to fit any interior or exterior space. From narrower doors for tighter spaces, to taller doors for higher ceilings, or wider doors for larger openings, there are plenty of options to choose from.

What are the different types of doors?

Before choosing the right size of your doors, you’ll want to choose the type of door you need. At Windows & Doors UK, we have several types of doors for you to choose from, including:

  • Oak French Doors: French doors are a popular option for patio and garden doors, as they provide a wide opening for easy access and a stylish, classic look. They consist of two doors that open outward and typically have glass panels to allow for natural light.
  • Bi-Fold Doors: Folding doors are an excellent option for creating a seamless transition between indoor and outdoor living spaces. They consist of multiple panels that fold together accordion-style and can be fully opened to create a large, open space.
  • Sliding Doors: Sliding doors are a space-saving option that allows for easy access to outdoor spaces while providing excellent natural light. They consist of one or more panels that slide horizontally along tracks, making them ideal for areas where space is limited.
  • Patio Doors: Patio doors are an excellent option for accessing outdoor spaces from living areas, such as a deck or patio. They typically have large glass panels that provide natural light and a wide view of the outside.

Each type of door has different sizes and functions, so it’s essential to choose the right one for your needs.

How to measure for a door?

Measuring for a door might seem like a straightforward process, but it’s important that you get accurate measurements to ensure a proper fit. To start, you’ll need to measure the height and width of the door frame from inside edge to inside edge. This means measuring the distance between the two sides and the top and bottom of the frame. It’s important to measure in several places to ensure that you get consistent measurements, as door frames may not be perfectly square or level.

When measuring the height, take three measurements: one at the left-hand side of the frame, one at the centre, and one at the right-hand side. Use the smallest of these measurements as your final height measurement. Similarly, when measuring the width, take three measurements: one at the top, one at the centre, and one at the bottom. Again, use the smallest of these measurements as your final width measurement.

Measure the depth of the door frame too, i.e. the distance from the front edge to the back. This will help you select the appropriate door thickness for your frame.

Taking accurate measurements is key to ensuring that your door fits properly and operates smoothly. If you’re not confident in your measuring abilities, call in the professionals to ensure you get the right measurements for your door.

Standard door sizes for patio doors

Patio doors are a popular feature in many homes, as they offer a seamless transition from indoor to outdoor living spaces, and allow for ample natural light to enter the home. When it comes to standard sizes for patio doors, they are typically wider than traditional doors, as they need to accommodate a larger opening.

The standard sizes for patio doors usually range from 1800mm to 2400mm in width, and 2100mm to 2500mm in height. These sizes provide a wide entrance to your patio, making it easier to move furniture or other large items in and out of the house. They also offer an unobstructed view of the outdoors, which can be particularly beneficial if you have a beautiful garden or scenic landscape surrounding your home.

At Window & Doors UK, we offer a range of standard and customisable sizes for patio doors, including sliding doors and bi-fold doors. Our patio doors are designed to offer both functionality and style, with energy-efficient glass and secure locking mechanisms to keep your home safe and comfortable. Whether you’re looking to replace an existing patio door or install a new one, our team of experts can help you find the perfect size and style to suit your needs.

Door size for disabled access

Door size for disabled access is not just an essential consideration when designing a building or a home, but in some cases, a legal requirement, as the Disability Discrimination Act (DDA) made it mandatory for all public buildings to have appropriate access for disabled people.

The size and accessibility of doors in a building can have a significant impact on the quality of life of individuals with disabilities, and it is important to ensure that they are designed with their needs in mind.

A standard door size for disabled access is 926mm x 2040mm (2ft 11.3” x 6ft 8.3”). This size allows wheelchair users to pass through the door with ease. However, it is also important to consider other factors, such as the door handle, which should be at a height that is easily reachable for wheelchair users, and the threshold, which should be level to the ground to prevent tripping hazards.

Can I customise the door size?

Custom-sized doors offer an ideal solution for non-standard doorways, older buildings, or unique architectural features. It is important to note that the customisation process requires precision and accuracy, as improper measurements could result in an ill-fitting door. If you do want to go down this route, always consult with a professional door supplier to make sure your custom door fits perfectly and meets all necessary regulations and requirements.

How to choose the right door size for your home

Choosing the right door size for your home is an important decision, and it’s essential to consider all factors before making a choice. One of the most important factors to consider is the size of the room. A smaller room may require a smaller door to maximise the available space, while a larger room may require a bigger door to make a grander statement.

Another factor to consider is the type of door. For example, a French door or patio door may require a wider opening to allow for better access to outdoor spaces. Similarly, a sliding door may require a different size than a traditional hinged door.

Lastly, it’s crucial to ensure that the door complies with building regulations. These regulations mean your new doors are safe and secure, and meet the required standards for insulation and energy efficiency. By choosing a door that complies with building regulations, you can be sure that you are making a safe and sustainable choice for your home.

Why timber doors are the best option

Windows & Doors UK only supply timber doors for several reasons. First and foremost, wood is a strong and durable material that can withstand everyday wear and tear. It is also a good insulator, helping to keep your home warm during the winter and cool during the summer.

As well as that, wood is an excellent choice for aesthetic reasons, as it offers a timeless and classic look that can complement any style of home decor. Wood doors can also be customised with different finishes and stains to match your desired look.

Not to mention, wood is a sustainable and eco-friendly material, as it can be sourced from responsibly managed forests and is biodegradable.

How to install a door

Installing a door can be a complicated process, especially if you lack the necessary skills and tools. However, if you’re confident in your DIY abilities, you’ll need to start by removing the old door and any hardware attached to it. You’ll then need to prepare the door frame by cleaning and leveling it before fitting the new door. Make sure to follow the manufacturer’s instructions carefully and use the recommended tools for the job. It’s important to ensure that the door is level and secure to prevent any issues with opening, closing, or locking.

Maintaining your doors

Maintaining your doors is an essential part of keeping them in good condition and ensuring that they last for many years. Regular cleaning is essential. If you notice any issues with your door, such as cracks, warping, or damage, address them promptly to prevent further damage.

  • Use a mild soap and water solution to clean the door surface. Avoid using harsh chemicals or abrasive cleaners that can damage the finish.
  • Lubricate the hinges and locks to prevent squeaking and ensure smooth operation.
  • Tighten any loose screws or hinges to keep the door secure.
