Standard French Door Dimensions Guide (2026)

Standard French door dimensions: interior, exterior, and double door sizes with rough openings. Learn how to measure correctly and when custom sizing is needed.

When standard sizes do not fit your project, custom French doors are a practical solution. As a manufacturer, Jusen Door and Windows produces custom-sized French doors and other door and window systems for residential and commercial projects. We adjust profile structures and fittings to match the building codes of your target market, and our factory-direct model means you source without middleman markup. If you are working with non-standard dimensions or need guidance on specification, contact our team with your rough opening measurements, and we will confirm what is possible for your project.
