A backup assist system for a vehicle reversing a trailer includes a trailer sensor module generating a trailer yaw rate and a vehicle sensor system generating a vehicle yaw rate and a vehicle speed. The system further includes a controller determining an estimated length of the trailer based on an estimated hitch angle, the vehicle yaw rate, the vehicle speed, and the trailer yaw rate in view of a kinematic relationship.
