Using a stadiometer correctly ensures accurate measurements: - The child should stand barefoot on a flat surface, with heels together and back straight. - The head, shoulders, buttocks, and heels should touch the vertical ruler. - The child’s head should be positioned in the Frankfurt Plane where the lower orbit of the eye is aligned with the upper margin of the ear canal. - The horizontal headpiece should be lowered to rest gently on the top of the child's head, compressing the hair. - Read the measurement at eye level to avoid parallax error.
