Construction of molecular architectures with precise dimensions is crucial in biology, and in the design of artificial nanosystems. The Vernier concept is one method of controlling molecular length.[1, 2] Here we report the synthesis of a giant porphyrin [12]nanoring using the mismatch in the number of binding sites between a hexa-pyridyl template and zinc porphyrin tetramer, via a figure-of-eight intermediate. Extension of this approach could allow access to even larger nanorings. [1] T. Ross Kelly, R. L. Xie, C. Kraebel Weinreb, T. Bregant, Tetrahedron Lett. 1998, 39, 3675-3678[2] C. A. Hunter, S.
