COMPARISONS BIG AND SMALL

Answers for anyone who has ever wondered whether a horse is faster than a hare or what the weight of a blue whale is—in tyrannosaurs.

In a mix of infographics and captions, both of which incorporate units of measure conventional and otherwise, each spread brings together assorted animals, weather phenomena, record setters, very big machines, or other thematically linked images or items as invitations to make comparisons. Along with being drawn reasonably close to scale, the figures are positioned to make those comparisons easy. They also often incorporate visual expressions of certain measures so that viewers can instantly contrast, for instance, the heights of the Empire State Building and the Burj Khalifa or the amount of water in a typical cat, dog, human (both baby and grown-up), cactus, and wedge of cheddar. Where humans are involved, as in lineups showing stages of development from newborn on or the seven children (one in a wheelchair) that measure up to one triceratops, Seixas consciously mixes gender presentations, races, and ages. Much of the information in the art and in Gifford’s quick comments looks to be averages or estimates—and is hard to check since sources go unmentioned. Still, this considerably streamlined spinoff of his The Book of Comparisons, illustrated by Paul Boston (2018), will clue younger audiences in to diverse ways of sizing up the world around them.

Playful measures and matches, whether measured in inches or dinosaurs.
