A vehicular trailering assist system includes a rearward viewing camera. Responsive to processing of frames of image data captured when the vehicle is towing a trailer hitched to the vehicle, the system determines presence of the trailer and determines if the particular trailer is a trailer for which the system is calibrated. Responsive to determination that the particular trailer is not a trailer for which the system is calibrated, the system assumes an initial trailer beam length before starting a calibration drive, collects data during the calibration drive, and estimates a trailer beam length. The system iteratively estimates the trailer beam length and, when the predicted trailer angle least deviates from the current determined trailer angle, the system determines this to be the final estimated trailer beam length and uses that in determining trailer angles for that trailer during future drives with the vehicle towing that trailer.
