An unfinished door allows you to decorate your home as you see fit. If you are looking to paint your door, opt for a gloss or semi-gloss paint. This is practical and hardwearing, meaning that they can withstand accidental knocks. They are also easier to clean. Always check the manufacturer's guidance before beginning decoration.
The most common internal door size in the UK is 6 feet 6 inches high by 2 feet 6 inches wide. The precise metric measurements of these doors are 1,981mm high x 762mm wide x 35mm thick. These sizes date back to the days when imperial, rather than metric, measurements were standard and are what’s found in the vast majority of domestic and commercial buildings. However there are many "standard" sizes for interior doors, and we list all of the available sizes for each model.
All the measurements you’ll see quoted on our site are for the inside of the door frame. To be sure that you’re buying the right size, take measurements of the width at the top, middle, and bottom of the door, and use the widest of these measurements as the door width you require. Do the same for the door height. Measure inside the vertical side of the frame and use the longest length to get the height required.
Interior doors tend to open inwards into rooms, because if they were fitted to be outward opening, they are likely to encroach on a hallway or other kind of common area of some kind. However, depending on the location of furniture, light switches etc., sometimes it may be necessary to have a door opening back out into a hallway.
