20-year-old boy, height 183, weight 72KG, what is my girth?

I think what you want to ask is what your measurements should be.

Calculation method of male standard measurement:

Chest circumference: height *0.6 1, then you are183 * 0.61=1.6cm.

Waist circumference * 042 76.9cm

Hip circumference: height *064 1 17cm.

Of course, this standard is very high.

But don't let your waist-hip ratio be greater than 0.9, otherwise it will be unhealthy.
