Comparisons

Two sourced heights, one scale. Athletes, animals, landmarks and dinosaurs side by side.

Each comparison is a page of its own, with both figures, their sources and the difference in centimetres and feet. Every one is chosen by hand and built from the sourced catalog; nothing is generated by combining names.
