Question: are french doors a standard size?
Answer: The sizes that your French doors come in will be set by the manufacturer, but they are generally between 30 and 72 inches wide per door. ... However, these will generally be around 120cm (1200mm), 150cm (1500mm) or 180cm (1800mm) wide for pairs of doors, and even wider for doors with sidelights (up to 300cm or 3000mm).
