Standard Doorway Measurements in the UK
In the UK, door sizes are standardised to simplify manufacturing and installation, but there are still variations depending on the door’s purpose.
Standard Internal Door Dimensions
The most common internal door size is 1981mm (6’6″) in height and 762mm (2’6″) in width. This size fits most homes and balances practicality with style. Other common widths may exist to accommodate smaller spaces or wider openings.
Standard External Door Dimensions
External doors, like front doors, are generally larger to accommodate frames and additional hardware. The standard height tends to be 2100mm in height, with a width of 900mm, offering a more imposing look.
Bespoke Door Sizes
Older homes or unique architectural designs may require custom door sizes. In these cases, suppliers like GFD Homes provide bespoke solutions to ensure a perfect fit.
Measuring Your Doorway
Accurate measurements are the foundation of a successful door installation. Here’s how to measure your doorway:
Step 1: Measure the Height
Using a tape measure, record the distance from the floor to the top of the door frame. Take measurements at multiple points and note the smallest value to ensure accuracy.
Step 2: Measure the Width
Measure the distance between the two vertical sides of the door frame at the top, middle, and bottom. Again, use the smallest measurement for precision.
Step 3: Measure the Depth
The depth, or thickness, of the doorway should match the door’s frame to prevent fitting issues.
Step 4: Account for Clearances
If flooring or carpets are being installed, factor in the extra height they add to the finished surface.
What Tools Do I Need to Measure My Doorway?
Measuring your doorway is a simple task that doesn’t require professional-grade tools. You’ll only need a few basic items:
- Tape Measure: Use a reliable tape measure that’s long enough to cover the full height and width of your doorway.
- Pencil and Notepad: Write down your measurements to avoid errors.
- Spirit Level (Optional): Helpful for checking if your doorway is level, especially in older properties.
- Helper (Optional): While you can measure solo, having someone hold the tape measure in place can make the process easier.
With these tools, you can accurately measure your doorway in just a few minutes. Don’t rush—taking your time ensures you get the precise dimensions needed for the perfect fit.
Common Challenges with Doorway Measurements
Even with standard dimensions, some challenges may arise:
Irregular Frames
Older properties often have irregular door frames, making it tricky to find an off-the-shelf solution. Bespoke doors are ideal in such cases.
Changes in Flooring
Installing new flooring can affect the doorway height, so consider this during renovations.
Hinges and Hardware
Don’t forget to factor in the positioning of hinges and hardware, as these can affect the final fit and functionality.
The Importance of Doorway Size in Accessibility and Design
A well-sized doorway isn’t just about fitting a door; it’s about functionality and comfort.
Accessibility
Wider doorways make it easier to move furniture, accommodate wheelchairs, and future-proof your home for diverse needs.
Aesthetic Impact
Larger doorways can create a more open and inviting feel, especially for front entrances. Taller doors, for example, add elegance and grandeur to modern homes.
Do I Need a Professional to Measure Up?
The short answer is no—you don’t necessarily need a professional to measure your doorway. With a tape measure and some care, most homeowners can take accurate measurements themselves. However, if you’re unsure or want extra peace of mind, whoever installs your door will typically offer a survey to double-check your measurements.
