What is a foot measurement chart?

A foot measurement chart is a sheet (usually paper) that measures the length and width of a person’s feet in inches to help determine shoe size, says About.com. Size matters and the information visible on a foot measurement chart should always cross reference with a manufacturer's shoe charts.

The simplest version of a foot measurement chart is a piece of paper that a person can stand on barefoot. Tracing around the largest foot with a pen or pencil, and then measuring the foot's length and width using a tape measure or ruler, gives the coordinates of a foot measurement chart.
