Body fat percentage
The following body fat percentages are guide values (contact your physician for further information).
Man
Age low normal
10 –14 <11 % 11–16 %
15 –19 <12 % 12 –17 % 17,1– 22 % >22,1 %
20 – 29 <13 % 13 –18 % 18,1– 23 % >23,1 %
30 – 39 <14 % 14 –19 % 19,1– 24 % >24,1 %
40 – 49 <15 % 15 – 20 % 20,1– 25 % >25,1 %

70 –100 <18 % 18 – 23 % 23,1– 28 % >28,1 %
A lower value is often found in athletes. Depending on the type of sports, training intensity and physical
constitution, values may result which are below the recommended values stated. It should, however, be
noted that there could be a danger to health in the case of extremely low values.
Body water percentage
The body water percentage is normally within the following ranges:
Man
Age poor
10 –100 <50 %
Body fat contains relatively little water. Therefore persons with a high body fat percentage have body
water percentages below the recommended values. With endurance athletes, however, the recommended
values could be exceeded due to low fat percentages and high muscle percentage.
This scale is unsuitable for measuring body water in order to draw medical conclusions concerning
age-related water retention, for example. If necessary ask your physician. Basically, a high body water
percentage should be the aim.
