The scale and proportion for humans in pre-adolescence:
A pre-adolescent figure should be between 3-5 heads tall (depending on age and height).Their facial features should be larger and the males jaw should be sharper than a female.
Males should have longer limbs (limbs proportioned for an adult, rather than the current body size).Remember, the marking stone for “teens” is their awkwardness.They are growing into their adult bodies, and thus their dimensions are a strange combination of adult and child.Each person will have a slightly different dimension, but the scale and proportion for human pre-adolescent females should be shorter than males.
Tips on Infants:
Scale and proportion for human infants are even smaller.
Depending on the age, the infant should be three-four heads tall.The second head makes up the body, while the third head makes up the legs.The body and limbs should be fat and the head very round.
A good rule for infants is to draw them with circles, no lines.
The scale and proportion for humans’ infant faces are simple: large eyes, nose, and mouth.Most infants have the same mouths, very defined with a rounded upper lip for sucking.
