Replacing regular doors with internal bifolds

If you’d like to maximise the amount of light in your home, want to create more open plan space or have small space you’re looking to make the most of, internal bifold doors are the perfect option.

However, if you’re looking to replace the regular doors or an old door within your home with an internal bifold door, there are a few important factors to consider.

What is meant by a regular door?

A regular door refers to any kind of internal door. Homes in the UK vary considerably in both age and style and, of course, in dimensions. However, the most common internal door size in England and Wales is 1981mm x 762mm x 35mm (also referred to as 2’6”).

Even if your current internal doors are not standard sizes, internal bifold doors are available in a range of sizes and can be made-to-measure which makes replacing your internal doors with bifolds simple.

Why replace your regular internal door with a bifold?

There are a number of reasons to consider replacing your regular door with a folding door:

Connect two rooms

You may want to connect two rooms together but keep the option of screening the space if necessary. As well as practical purposes, there’s no denying the spacious feel you get from being able to fold doors back and having beautiful internal bifolds that echo the look of a patio door creates a sense of continuity and flow for your home.

A bifold door can also be used as a closet door to help make the most of the space in your home but provide privacy when needed.

Add more light to a room

You may have a gloomy office or a closet space that would benefit from additional light. Internal bifold doors can help to maximise the amount of light in your home and make the rooms they connect feel brighter, even when the doors are closed. Our Finesse range is perfect for brightening up a space and features clear glass within the door frame in the same way as external bifolds to help maximise the light within your home. On the other hand, our Finesse Frosted range, which features frosted glass, is great for anywhere that requires extra privacy when the doors are closed, such as a closet.


Internal bifolding doors give you real flexibility in how you use your space. You may have a kitchen diner and love open plan living but you may want to close the space off from time to time. Bifold doors let you adapt and alter your space quickly and easily.


Internal bifold doors will add a modern feature to your home and, with a range of colours and styles available, you’ll find something to match your home décor. Vufold’s range of internal bifold doors is available with an oak, white or custom door frame so there’s something to match every style and taste.

  • Measure diagonals from corner to corner to verify that the opening is square
