Bifold doors are a popular choice for homeowners looking to combine indoor and outdoor spaces seamlessly. They are ideal for patios, kitchens, and living rooms, providing wide openings, natural light, and a modern look. If you’re considering bifold doors, it’s important to understand the standard sizes available and how to choose the right dimensions for your home.

Standard Widths for Bifold Doors
Bifold doors consist of multiple panels that fold back against each other. The width of each panel typically ranges between 18 inches (450 mm) and 36 inches (900 mm). Common configurations include:
- 2-panel doors: 3–6 feet wide (900–1800 mm)
- 3-panel doors: 4.5–9 feet wide (1350–2700 mm)
- 4-panel doors: 6–12 feet wide (1800–3600 mm)
- 6-panel doors: 9–18 feet wide (2700–5400 mm)
The total width depends on the number of panels and the desired opening size.
Standard Heights for Bifold Doors
Most bifold doors come in a standard height range of 78–96 inches (1980–2440 mm). Some homes or commercial spaces may require taller doors, which can often be customized for a perfect fit.
Custom Bifold Door Options
While standard sizes work for many spaces, custom bifold doors are popular for larger openings or unique architectural designs. Aluminium bifold doors can be tailored to:
- Fit unusually wide or tall openings
- Match specific ceiling heights
- Accommodate multi-panel configurations
Custom doors ensure smooth operation, proper alignment, and a sleek, modern finish.
