How to Measure Body Weight and Height

Body Mass/Weight

For consistency when a client takes their weight follow the steps below:

• No shoes
• Minimal clothing and ideally the same clothing each time
• Stand still, weight needs to be spread evenly while standing on scales
• Preferably weighed the same time of day or evening
• Record in kilograms.

Height

For consistency follow the steps below:

• No shoes
• Watch the hair – Hair tied up high will give an incorrect reading
• Stretch upward while inhaling
• Measure vertex of client’s head – the vertex is the very top of your head.

Body Measurements

• Take the measurement before exercise
• Encourage the client to remove any bulky clothing
• Take girth measurements last after all other measurements have been taken
• Be quick and efficient and conscious of the client’s possible discomfort
• Measure from the same side each time
• Ensure the tape measure is level around the client
• The tape should be firm but not cut in
• Always hold the tape measure the same way
• Take notes to ensure future consistency.
