A handy guide to standard UK door sizes
It’s true to say that doors come in all different sizes, so we’ve used our expert knowledge to put together this handy guide to standard UK door sizes to help you understand what doors fit best and why.
Is there a ‘standard’ UK door size?
Yes, there are standard UK door sizes but you must be explicit in whether it’s a front door (external door) or internal door that you need to size. They’re definitely not the same! And, obviously, doors come in a variety of widths for various reasons. Interestingly, however, the standard (or most common) height of doors is 78 inches, 6’6” or 1981mm depending on which unit of measurement you prefer to use!
When it comes to the width of a door, the standard UK door sizes are 711.2mm (28 inches), 762mm (30 inches), 812.8mm (32 inches) or 914.4mm (36 inches).
Now, we’ll take a look at specific types of doors and see how their sizing compares.

External door sizes: is there a standard size here too?
When we talk about external doors here at Secure House, we’re usually referring to a front door. Let’s start with a conventional front door for a residential property. Typically, the front door of your home will be either 762mm (30 inches) or 838 (33 inches) wide and 1981mm (78 inches) high.
Over the last few years, there has been a clear trend towards ‘oversize’ doors and double doors, both of which are specifically designed to create a very grand entrance.
Internal door sizes explained
Continuing with the same external standard door height of 1981mm (78 inches), the standard UK door size for an internal door is 1981mm (78 inches) x 762mm (30 inches). In the joinery industry, you may hear a joiner refer to this as a 2’6” door.
However, as with front doors, there is also the option of creating smaller or wider openings into certain rooms and double doors linking, for example, a dining room to a living room are very popular since they can transform a room for a relatively small investment.
When purchasing internal doors, it is important to take into account the type of property they to be installed in. Whilst the standard internal door size in the UK is 1981mm (78 inches) x 762mm (30 inches), period properties often have wider openings so it’s vital that you measure the aperture correctly before you buy. This is one of the reasons we offer a professional measuring service.
Equally, new build properties offer the chance to create a truly bespoke internal door size to suit the type of home being built. You may wish to go for slightly wider internal doors, add double doors or space-saving sliding doors for certain rooms.
Allowing for disabled access
When taking into account disabled access either into a private residence or commercial building, the width of the door needs to be closely considered. We would recommend using doors of at least 900mm (35.4 inches) in width to allow comfortable access for wheelchair users.
Bespoke doors. Yes, they really are a thing
And, finally, just a brief note to say that doors can be created to any size or specification in our world-class manufacturing facility. So, if standard really isn’t your thing, just ask!

Door Materials and Finishes
When it comes to internal doors in the UK, the choice of materials and finishes can significantly impact both aesthetics and durability. Solid wood doors, known for their timeless appeal and sturdiness, are a popular choice. Engineered wood doors offer a more cost-effective option while maintaining a wood-like appearance. Meanwhile, MDF doors, often used for their versatility, can be easily painted to match any interior decor. The finish of the door, whether it’s painted, stained, or laminated, also plays a pivotal role in achieving the desired look and feel within your living spaces. Consider the overall style of your home and personal preferences when selecting the material and finish that best suits your needs.
Fire Door Regulations
In the United Kingdom, fire safety is of paramount importance. Therefore, it’s crucial to understand fire door regulations, especially when choosing doors for areas like kitchens and escape routes. Fire doors are designed to contain the spread of fire and smoke for a specified period, giving occupants valuable time to evacuate safely. These doors are rigorously tested and must meet specific size and performance criteria. It’s essential to consult building regulations or a professional to ensure you’re using the correct fire-rated doors in the appropriate locations to comply with safety standards.
For peace and tranquility within your home, consider the acoustic properties of internal doors. Thicker doors with solid cores tend to provide better sound insulation, making them ideal for bedrooms, home offices, or any space where privacy and reduced noise intrusion are essential. Additionally, you can explore the option of acoustic seals and weatherstripping to further enhance soundproofing. When selecting doors, pay attention to the Sound Transmission Class (STC) rating, as it indicates the door’s ability to reduce sound transmission.
Door hardware, including handles, locks, and hinges, not only influences the functionality of your doors but also adds a touch of style. The choice of hardware should complement the door’s design and your interior decor. Lever handles, for instance, offer ease of use and can suit modern aesthetics, while traditional knob handles may be more fitting for a classic interior. High-quality locks and hinges are essential for security and smooth operation, so invest in reliable hardware that matches your door’s purpose.
Door Installation Tips
Proper installation is key to ensuring that your doors function correctly and look their best. Whether you’re replacing an existing door or installing a new one, precise measurements are critical. Ensure that the doorframe is level and plumb, and consider consulting a professional installer if you’re uncertain about your DIY skills. Proper alignment, hinge installation, and sealing gaps are essential steps to prevent drafts and ensure the door swings smoothly.
Maintenance and Care
To extend the lifespan and appearance of your internal doors, regular maintenance is necessary. Depending on the door’s material and finish, maintenance tasks may include periodic cleaning, refinishing, or resealing. Keep an eye out for signs of wear and tear, such as scratches or dents, and address them promptly to prevent further damage. Lubricate hinges and locks as needed to ensure smooth operation. A well-maintained door not only functions optimally but also adds to the overall appeal of your home.
Energy-efficient doors can contribute to a more comfortable and cost-effective living environment. For external doors, consider those with effective weatherstripping to prevent drafts. Insulated doors can help regulate indoor temperatures and reduce energy bills. If privacy is a concern, you can choose doors with energy-efficient glazing options that allow natural light to enter while maintaining thermal efficiency. Investing in energy-efficient doors is not only environmentally responsible but also financially beneficial in the long run.
The cost of internal doors can vary significantly based on factors like materials, size, style, and brand. Solid wood doors tend to be pricier than MDF or engineered wood options, and customized or bespoke doors will typically come with a higher price tag. It’s essential to establish a budget before shopping for doors and weigh the benefits of different materials and features against your financial constraints. Keep in mind that while high-quality doors may have a higher upfront cost, they often offer greater durability and long-term value.
Interior Design and Styling
Internal doors play a pivotal role in interior design and styling. The choice of door style, color, and finish can impact the overall aesthetic of your home. For a cohesive look, consider doors that complement your existing decor and architectural style. Modern homes may benefit from sleek and minimalist door designs, while traditional interiors may call for more ornate and classic options. Don’t overlook the potential of doors as design elements; they can add character and elegance to your living spaces.
Online Resources and Tools
In today’s digital age, numerous online resources and tools are available to aid in your door selection process. You can find door size calculators to determine the right fit for your openings, browse design inspiration galleries to visualize various door styles in different settings, and even use virtual room planners to experiment with door placement and design. These online resources can be valuable aids in making informed decisions and ensuring that your chosen doors align with your vision for your home.
Allowing for Disabled Access
When considering door sizes, it’s crucial to factor in accessibility, especially for private residences or commercial buildings. Wider doors, typically at least 900mm (35.4 inches) in width, are recommended to accommodate wheelchair users comfortably. Ensuring that your doors are wheelchair-friendly is not only a matter of convenience but also a legal requirement in many cases. Consider the needs of all potential occupants or visitors to your property to create an inclusive and accessible environment.
For those who desire a truly unique and tailored solution, bespoke doors offer endless possibilities. These doors can be created to any size, style, or specification in specialized manufacturing facilities. If the standard door sizes or designs do not align with your vision, bespoke doors allow you to express your creativity and design preferences fully. Keep in mind that while bespoke doors offer flexibility, they may come with a longer lead time and higher costs due to their customized nature.
