HOW TO MEASURE YOURSELF

Α. Half waist
The circumference measured horizontally around the waist, just above the highest point of each of the iliac crest bones, during normal breathing, on the person standing, with a relaxed abdomen. 

Β. Height
Stand against a flat wall with your back straight and your heels touching the wall. Use a pencil to make a small mark on the wall at the highest point of your head. Measure the distance from the floor to the mark.
