The invention is a foot measurement system suitable for mailing to consumers. The primary components of the measurement system include a length portion for determining the length of the foot and a width portion for determining the width of the foot. The length portion and the width portion each include sliders that may be positioned in an abutting relationship with areas of the foot. When the sliders are properly positioned, foot dimensions may be determined by reference to scales on each of the length and width portions. The measurement system also includes a container, for receiving and supporting the length portion and the width portion, that is suitable for use as a shipping container. In addition the measurement system may include a calibration device for ensuring measurement accuracy and a register for recording measurements.
