The flexible opening mechanism of folding doors frees up significant space in homes, making them increasingly popular among modern consumers. Consisting of multiple panels connected together, these doors slide and fold open by being pushed to the side, minimizing their footprint and saving valuable floor space. Evolving from the ancient Chinese screen to today’s balcony and kitchen doors, the practicality and functionality of folding doors continue to grow. Meanwhile, materials like PVC, wood, and aluminum alloy are constantly improving to meet diverse design and durability needs. However, many homeowners remain unsure about the ideal size for their folding doors and what specific dimensions are required. Today, we’ll reveal the standard sizes commonly used for folding doors!
Standard dimensions of folding doors
In practical applications, the dimensions of folding doors vary depending on the environment. While the height is somewhat limited and changes only slightly, other dimensions—such as the number of door panels and their width—are largely undefined. As a result, ready-made folding doors are rare on the market; most are custom-made to meet specific needs. However, according to "Standard Dimensions for Interior Design in Residential Spaces," typical folding door sizes in current home decor designs range from 450 to 600 mm in width and 1900 to 2400 mm in height—these are widely accepted standard dimensions in interior design projects.
Indoor Folding Door Size Requirements
When the maximum single-leaf width is 1000mm or less, the leaf height must be 2400mm or less.
When the maximum height of a single door leaf is 3,500 mm or less, the leaf width must be 750 mm or less.
Maximum single-leaf weight is less than or equal to 80 kg;
If 8+9A+8 glass is selected, the weight is 40 kg per square meter; if 6+9A+6 glass is chosen, the weight is 30 kg per square meter.
Folding doors are almost entirely different from standard interior doors—think sliding doors, hung-and-sliding doors, and swing doors. As a result, they require extra care during use compared to conventional doors, and regular maintenance is essential to keep them in top condition.
