Bi-fold doors are a popular choice for homeowners and businesses due to their stylish design and space-saving functionality. However, you need to know the correct bi-fold door size you’ll need to ensure it fits properly in the desired location. 

The problem comes when either you don’t take the accurate door size measurements that you need or you don’t understand the sizing of bi-fold doors. We recommend that before going to buy a bi-fold door, make sure you look through the measurement process to avoid any hassle. 

What are Bi-Fold Doors?

They are made of multiple panels that fold up against a wall when opened and are made to slide open. Most modern homes are built with conventional, single-leaf doors, but they can be extremely inconvenient when you're trying to maximize your space.

Bi-fold, or bi-folding, doors have gained popularity as an alternative to exterior sliding patio doors. They were initially created as internal doors to save space. Creating a seamless space between the inside and outside is made possible by bi-fold doors' floor-to-ceiling glazing. A bifold door pivots to open flat against the sides, whereas a sliding door can only open half of its aperture.

A bifold door pulls open from the middle and gives a full view and full entry to what's behind the door in one quick move. This is a more appealing, robust, and distinctive option. Additionally, the vibrating sound you typically hear with sliding doors will also disappear thanks to the tremendous weight of the strong doors.

Bifold doors can be installed inside your home, or outside to open up a garden or conservatory. They can also be installed as an alternative way to create spaciousness in a larger room. As far as flexibility goes, there is no better option!

How are Bi-Fold Doors Sized?

1.8-meter and larger brickwork openings can be fitted with bi-fold doors. In the largest openings, there may be up to six doors. They come in a variety of sizes and door patterns.

Six doors can be configured in different ways, for example, three + three doors (so the doors fold on each side), or five + one door. Furthermore, you need to consider the door height as well; the standard opening is 2095mm high. It would be necessary to have them custom-made if you required other sizes.

Bi-fold doors on the outside are usually wider than bi-fold doors on the inside, although they're seldom that taller. It's just a bit taller than an internal door, but standard bi-fold doors are usually 2090mm or 2100mm high. It can range from 1800mm for two-panel bi-fold doors to 4800mm for six doors, depending on your aperture.

Bi-fold doors aren't the only kind of external doors we've got. Aluminum bi-fold doors are usually bigger too. With a mechanical join, it can be made much wider than 6250mm. There's no limit to how wide the panels can be, but certain styles can be up to 1200mm wide. They're usually only used for commercial stuff.

If you order doors, use MM measurements instead of CM; it won't seem like much of a difference, but it'll make a huge difference both in terms of energy efficiency (draft prevention) and security. Getting the right size for your door opening is important if you're not sure.

How Do You Measure The Size Of A Door?

It's important to measure accurately to ensure that the door will fit properly and function smoothly. In a nutshell, measuring the size of a door involves measuring the door's height, width, and, thickness. We’ll look into the measurement processes one by one.

Measure the Door Width

Inside the door frame, you should measure three things: the top, middle, and bottom of the door frame. A door's width is determined by the measurement at its widest point.

• Tape measure the doorframe's three core areas to determine their widths. From left to right, measure the frame's width with a tape measure.

Measure Door Height

Take a measurement of each vertical side. Height is determined by the longest length. Make sure you account for floor coverings.

• To figure out how tall the door frame is, use a tape measure. Record the longest length on each side by running the tape from top to bottom.
• Do consider that for measuring, you may need to stand on a chair to run the tape on top of the frame. It will be best if someone helps you through the process.

Measure Door Thickness

Taking measurements of the door thickness will be necessary if you plan to buy replacement doors and keep the same frames.

• Make sure you know the thickness of the existing door by using a tape measure. Take a tape measure and measure the thickness along the edge of the door.
• If the door sits in the rebate when closed, you need to measure it too.

Summary

In summary, choosing the right size for your bi-fold door is essential to achieve the desired functionality and aesthetic. Taking accurate measurements, considering the number of panels required and the available space for the door to fold back onto itself.

Another important consideration is the overall aesthetic you are trying to achieve. Bi-fold doors come in a range of sizes and styles, from traditional timber to contemporary aluminum, so it's important to choose a style that complements the design of your home or business. With these factors in mind, you can choose the perfect bi-fold door for your space.
