A system for automatic calibration of instruments (S) having varying cross-sectional dimensions within a predetermined range and having detectable elements () thereon for computer-aided surgery, comprising a calibration base (C) having detectable elements () secured thereto for detecting a position and an orientation thereof in space by sensors () connected to a position calculator (). The calibration base is adapted to receive and to releasably secure a working shaft () of any of the instruments (S) and provides an abutting surface () for a tip () thereof in such a way that a position and orientation of the tip () of the instrument (S) secured therein is calculable when working shaft cross-section dimensions thereof are known. The position calculator () receives instrument data () and calibration data () from an operator through a user interface () and stores the instrument data () and calibration data () for subsequent calibrations.
