Use the images below as reference pictures on drawing your own bodies. You can either 1) first sketch the body out and check to see if it fits with one of guides or you can 2) go ahead and mark 7 or 8 head lengths and sketch out the body using the marks as guides. :) It’ll take a while to get this down, so practice makes perfect!
7 Head Body
This will make your character a bit more cartoony or young. This would probably be the most popular proportion. Younger characters will have an even bigger head so their bodies will have even less “head lengths”. This is for both male and female characters.
Tips and Techniques
You can start getting the proportions correct easily by getting the shoulders right from the beginning. The range from smallest to largest would be be from 0 to 1. 0 meaning that the shoulders would be the same size of the head, and 1 meaning that the shoulder would come out 1 head width from the side of the head (look at the sky blue line in the picture).
You typically want to stay in the 1/4~1/2 range. I have drawn a 1/3 shoulder in purple in the image and a 1/4 in pink. The smaller the shoulder the cuter, more feminine, and more cartoony. The larger the shoulder, the more masculine and realistic. So the light blue shoulder (1) should be pretty much reserved for realistic masculine characters while the smallest (0) should be reserved for children :)
Here are some more tips and tricks to help you get that body looking right. This goes for all head sizes so you can use this even if you don’t use 7 or 8 head bodies :)
