Bike frame size and seat height chart below shows the dimensions of the frame size and seat height based on the inseam height. To choose the right bicycle and adjust the height of the saddle, first measure inseam height and then multiply the value by 1.08, which will give you the seat height (see the table below). This measurement can be used for both mountain and road bikes.
Getting the right bike size is important to maximize your speed, comfort and ability to handle, i.e. all the the things needed to ensure you get the best possible biking experience. It is important to use your personal measurement such as your height to choose the right bike frame and seat height. The bicycles are measured by the length of the seat tube, i.e. the tube where the saddle slides in to. Road bicycles are usually measured in cm while mountain bikes in inches. The diagram below will assist you with choosing the right bicycle regardless of the measurement system you are more accustomed to.
