A typical sheet of notebook or printer paper is around eight inches wide. Additionally, this length is equivalent to two-thirds of a foot-long ruler.
Eight inches is equivalent to 203.20 millimetres, or 20.320 centimetres, in metric measurements. Although many versions are an inch or two larger or smaller, the majority of tablet computers have screens that are approximately eight inches tall.
Eight inches is equivalent to two “hands,” where a hand is a measurement that has historically been used to gauge a horse’s height and was based on the typical width of a human hand. Up to eight-inch-long fossilised teeth from the predatory dinosaur Tyrannosaurus Rex have been found.
