An attachment calibration control system for a work machine where the system comprises a boom, an attachment, a boom actuator, an attachment actuator, a boom position sensor, an attachment position sensor, and a machine control module having a receiving unit, a calculation unit, and a calibration unit. The receiving unit is configured to receive a plurality of boom position signals and a plurality of attachment positions signal correlating to a plurality of sequential attachment position signals. The calculation unit is configured to calculate geometric parameters of the attachments based on the plurality of attachment position signal and the plurality of boom position signals correlating to the plurality of sequential attachment positions. The calibration unit is communicatively coupled to the boom actuator and the attachment actuator, and configured to adjust a default parameter of at least one of the boom position and the attachment position based on the geometric parameters of the attachment.
