The inventive concept relates to a skinfold caliper, wherein the skinfold caliper includes a first holder and a second holder respectively having tips approaching or moving away to or from a to-be-measured portion of a to-be-measured object, wherein the first holder and the second holder pivot relative to each other about a pivot axis, a scale unit provided in the first holder, wherein the scale unit has a plurality of angular scales formed along a rotation path of the second holder, a probe unit disposed in the second holder so as to electrically connect to the scale unit, wherein the probe unit senses a relative rotation angle of the second holder relative to the first holder, a pressure measuring sensor provided at the tip of one of the first holder and the second holder, wherein the pressure measuring sensor measures a pressure applied to the to-be-measured portion of the to-be-measured object, and a controller configured for, when the pressure measured by the pressure measuring sensor reaches a predetermined pressure, receiving rotation angle measurement data corresponding to an angular scale of the scale unit from the probe unit； and calculating the rotation angle measurement data into a linear distance between the tips of the first holder and the second holder.
