Bifold doors are a popular feature in many homes. Although they’re available in a range of sizes and configurations, they can be made to fit into almost any opening. Folding doors are extremely versatile and are available in many styles and sizes, with a range of materials to choose from including aluminium, timber or composite.

If you are looking to save space, add more light to a room or improve the look of the outside of your home, you may be considering bifold doors. This guide provides information in standard size bifold doors including how to shop, prepare for and fit them.

If you are looking to fit folding doors to the outside of your home, whether it’s to create a set of patio doors or to replace an old door, the first step is to research standard sizes and compare them to measurements you’ve taken from your property. Standard sizes are based on brickwork opening sizes so its important to have these measurements to hand when choosing the doors you need.

This will determine the frame size you will need and allow you to go ahead and order your doors immediately or help you decide whether or not you need custom-made bifold doors.

With a folding door you have the flexibility to choose how many panels you want to fill your space so the standard width measurement depends on the number of panels you opt for. Here are the standard height and width measurements for Vufold’s exterior bifold doors. These may vary from supplier to supplier so it’s important to check before placing your order.

Benefits of choosing standard sized bifold doors

The features that bifold doors can offer for your home make them attractive to many homeowners but there are also more technical benefits of installing standard sized bifold doors including:

  • As soon as you have the measurements for the opening for your bifold doors, you can head straight to Vufold’s range of doors and order the perfect doors for your home
  • Standard sized bifold doors are easy to order and fit
  • Available in a range of materials to suit the size and style of your home
  • Vufold doors are delivered to your home ready-to-assemble so you can fit them with ease straight away if you have basic DIY knowledge


Cons of choosing standard sized doors

Standard sized bifold doors are exactly that – they are based on standard or average sized openings. Due to this, you may struggle in finding a standard sized set of doors if you have an odd-shaped space or opening. Vufold supply custom-made bifold doors but the process may take a little longer.



How do you know which size bifold door you need?

Before choosing your bifold doors from Vufold’s extensive collection, you will need to measure the opening, or the area where your bifold doors will be fitted. This is not as difficult as it sounds! Follow these easy steps on how to measure for your new bifold doors to determine the door size you need for your home:

Step 1: Firstly, use a spirit level to measure the corners of the opening, or aperture.

Step 2: Next measure the width and height of the opening in millimetres. You will need to take these measurements from each side, and from the middle of the opening. The measurements you take will need to be exact as a few incorrect millimetres can affect the way your doors fit.

Step 3: Once you have the key measurements, subtract 10mm from the smallest measurement you have. This will be the size of your new bifold doors.

Step 4: Check that you will have enough space to fold doors back once they are installed.

Step 5: Take a look at Vufold’s large selection of standard sized bifold doors. It is important to note that bifold doors have a 10-15mm fitting tolerance so, if your measurements swing outside of the standard sizes by this amount, you may still be able to install a standard size bifold door.

Step 6: If your measurements still do not match up to any of the standard size doors listed, then you can order a bespoke size specially made for your opening.
