7 mm scale

7 mm scale, also known as 7mm to 1 foot scale or 7mm scale modeling, is a model scale primarily used in railway modeling. In this scale, 7 millimeters represents one foot in real life. This translates to a scale ratio of approximately 1:43.5. Models created in this scale are often used for modeling narrow-gauge railways and can also be seen in some broader applications like architectural models and dioramas.
