The scales have a circular scale (4) with an additional adjustable circular scale (6) arranged outside the main scale (4). The extra scale shows values for tallness (150-190) and the value for the person being weighed is set to zero (0) on the weight scale. The outer extra scale has an additional indicator (15) of the ideal weight of the person being measured, with negative and positive deviations from the ideal marked above and below the scale. The height values (10-14) and the normal weight markings (16-20) are coloured so that corresponding weights and heights have matching colours. |
