• Measure around the chest and body
at its fullest part (typically right
under the armpits and shoulder
blades, right across the nipples).
• Hold the tape against the body tight
enough so that it does not slip down,
but not so tight that it restricts
breathing. It should be “snug”.
• Make sure the tape is horizontal and
the person's arms are by their side;
then take a normal breath and measure.
• Do not puff out your chest
• Double check this measurement
