G scale is a model railway scale that represents a scale ratio of 1:22.5, where 1 unit in the model equals 22.5 units in the real world. It is primarily used for outdoor garden railways but can also be used for indoor layouts. G scale models are typically large enough to be easily seen and handled, making them popular among hobbyists who enjoy outdoor trains that can withstand varying weather conditions.
