Jumping spiders vary in size, but the largest species known is the giant jumping spider (Hyllus giganteus), which can reach lengths of about 1.8 to 2.5 centimeters (0.71 to 0.98 inches). Most jumping spiders are small to medium- sized, generally ranging from 2 to 22 millimeters (0.08 to 0.87 inch). For example, the largest jumping spider in eastern North America, Phidippus regius, can measure up to 22 millimeters (0.87 inch). Overall, jumping spiders remain relatively small compared to other spider types, with their size rarely exceeding about an inch.
