Chain sizing refers to the process of determining the appropriate length of a chain for a specific application. This involves measuring the distance between the two sprockets or gears that the chain will connect, and then adding an appropriate amount of slack to accommodate for movement and tension.

Once the correct length is determined, the chain can be cut to size and connected using a master link or other joining method. **

Mixed tire sizing can be found on some high-performance sports cars and off-road vehicles. **
