His work combines the anatomical study of the Northern tradition with the dramatic compositions found in Late Renaissance Italy. In Studie van een naakte man (Hercules?) en twee hoofden van vrouwen, Calvaert demonstrates a focus on muscular structure. His religious scenes, such as Geseling van Christus and Hemelvaart van Christus, use light to create focus without relying on complex arrangements. He often placed figures within rocky settings, as seen in Saint Jerome in the Wilderness, where the environment feels as deliberate as the subject.

Modern collectors value Calvaert for his ability to balance emotion with clarity. His drawings and paintings provide a window into the transition from Mannerism to the early Baroque period. These prints offer historical weight through their classical themes and disciplined execution. Works like Visitatie remain visually effective in contemporary spaces because they prioritised clear narrative and strong figurative drawing over excessive ornamentation.
