What is the standard size of a factory door?

The standard size of a factory door typically varies, but a common dimension is around 3 feet wide by 7 feet tall (36 inches by 84 inches). However, larger doors are often used in industrial settings, with sizes like 12 feet wide by 14 feet tall or even larger for equipment access. Specifications can vary based on the factory's needs, local building codes, and the type of machinery or materials being handled. Always consult industry standards or local regulations for precise requirements.
