A Guide to Buying Interior Bifold Doors

Bifold doors can do a lot for a home; they can update the look of your home, maximise your available space and join rooms together easily. There are tons and tons of different designs and styles of bifold doors, so choosing the door that would work best for your home and personal style can be a tough decision in itself. Today, we guide you through the process of deciding which internal bi-folding doors are the best option for you; covering everything from sizes, to finishes and even solid or glazed.

What Sizes Can I Get Bifold Doors In?

If you would like to keep the expenses down, looking at standard products and sizes is the way to go. Many of the doors that we sell here at Doors and More are able to be trimmed, so if you find you need to shave a couple of mm’s off in order for your door to fit perfectly, that’s not a problem! If you find that your bifold doors are catching on your carpet or are slightly too big, our guide to trimming your bifold doors will take you through the process.

When it comes to sizing, the options are endless. Generally here at Doors and More we stock two sizes of internal bifold doors; 27 inches (197mm x 338mm x 34mm) and 3o inches (1974mm x 375mm x 34mm). Picking the right size depends very much on the size of the aperture where you wish to install the doors. We highly recommend measuring your aperture in mm for the most accurate reading, and doing it three times to make sure your measurements are correct.

Once you’ve taken the measurements, if you feel like you’d like a little extra guidance before making a decision you can always give our team a call on 01205 363999. Our specialists would be more than happy to work with you to help pick the best doors for your needs.

Prefinished, Unfinished, or Primed?

Once you know the size of your doors, it’s time to think about how you want them to look. All internal doors are typically available in one of three finishes; prefinished, unfinished and primed.

Prefinished of Fully Finished

Doors with this finish have already been stained or painted and are ready to hang.


Unfinished doors are perfect for those who either want to match their doors to their existing skirting boards or style, or fancy creating something totally unique. Unfinished doors are a blank canvas and will require staining or priming and painting before you install them in your home. If you’re opting for unfinished doors, you might find our guide to painting internal doors helpful.


Primed doors are the middle-man between prefinished and unfinished. They are supplied primed and ready to be painted in the colour of your choice.

Interior Bifold Doors with Glass

Choosing the right doors for your home is a big decision; there are plenty of designs to choose from, including glazes options. Glazed internal doors are a rather popular options with homeowners for both internal and external doors. If you’re looking for a way to filter light through your home from room to room, then glazed bifolding doors might just be the answer that you’ve been looking for. As with the finishes, there are a number of options to consider when looking for glazed doors.

Clear Glazed

Clear glazed doors feature a transparent glass panel which allows plenty of light to flood through, and also allows you to see between rooms making them ideal for connecting rooms such as dining rooms, kitchens and lounges.

Frosted Glazed

Frosted glass is a great option for homeowners who want the benefits of additional light through their home, without sacrificing privacy. Typically frosted glass has been treated to create a translucent finish which allows through light, but obscures vision. These doors are fantastic for joining living spaces together, such as dining rooms and conservatories, and even offices.

When looking for glazed doors, it’s always worth looking for toughened glass. Toughened, or tempered, glass puts outer surfaces into compression and the inner surfaces into tension to increase its strength. This means that it is better able to withstand the day to day opening and closing, and the occasional slam, bump or knock, too.
