Accordion Door Sizes: Ultimate Guide & Measurement Tips

By Anthony KingApril 25, 2026

When it comes to maximizing space and style in your home, accordion doors are an excellent choice. These unique doors, also known as bi-fold or concertina doors, fold back on themselves to save space and create a seamless transition between rooms. But with so many sizes available, choosing the right accordion door can be overwhelming. Let's delve into the world of accordion door sizes to help you make an informed decision.

Accordion doors are typically measured in two ways: leaf width and overall width. The leaf width refers to the width of each individual door panel, while the overall width is the total width of the door when it's fully open. Understanding these measurements is crucial for selecting the perfect accordion door for your space.

Standard Accordion Door Sizes

Most accordion doors come in standard sizes to fit common doorways and openings. These sizes are usually measured in inches and can vary slightly between manufacturers. Let's explore some of the most common accordion door sizes.

Available Space: Consider the space on either side of the doorway. Accordion doors need space to fold back into, so make sure there's enough room for the door to open fully.

Traffic Flow: If the door will be used frequently, consider a wider leaf width to allow for easier passage.

Privacy and Light Control: If privacy or light control is a concern, opt for a door with a larger overall width to cover the opening more effectively.
