How Big Should An 11 Year Olds Waist Measure Cm?

Well I speak with advice on this one as I am trained as a Doctor but am currently modeling for vogue.
 
The width of the weist depends on how tall you are .
But it should be around 20-27 inches.
But for a child model ( I know its random 0 about 20-21
hope this is hepfull

25 - 30 inches

I'm 150cm tall and 33cm I'm only 35kg though so I have a massive waist and butt,  but I'm not that fat

I'm around 23 inches (58.42 cm)? Around 5 ft 2 inches. It really depends on your height and how early you develop.

For the person who has a 40 cm (15-16 inches) waist, unless you're less than 4' 5'', than you're definitely abnormal, or don't know you're actual waist size.

I'm eleven and I'm a 25, so I'd say around 22-26

I'm 11 mine is 34 in I wish I could lose some of my belly fat before I go 2 middle school. Maybe around 24 in.

I'm not sure but I am almost 11 and I am 25 inches that's normal right
