Drawing the Human Body: 5 Tips for Drawing the Torso
The torso is the largest part of the human body, protecting the main vital organs. It can be divided in two sections: pectoral and abdominal.
Drawing the human torso can be difficult. As an artist, it helps to know the major muscles groups and bones that are visible on an average model, but you don’t need to take an anatomy class before mastering how to draw this part of the body. Memorizing all the bones and muscles by name and knowing their exact location just isn’t necessary. With a few helpful tips, you can get it right without memorizing a single flashcard.
Here’s some tips for drawing the human torso
1. Know the differences between male and female torsos
Even though every individual has a uniquely shaped torso, there are some differences between male and female that apply in general:
- Males usually have longer torsos than females.
- Females have a bit more subcutaneous body fat. Accordingly, their shape is a rounder, and the muscles are a less defined.
- Female hips are wider, and their waist is usually a touch higher than in males.
- Shoulders are typically wider in males.
- Usually the length of the spine is a bit shorter in a female than in a male.
- Male nipples are further apart than female nipples, which are more centered.
2. Consider the angles
Angles are an important part in rendering a realist drawing of the human form. Each shoulder is located the same distance from the spine (middle of the torso). You can draw a line in the middle of the torso to help with symmetry.
The angle of the shoulders should counterbalance with the angle of the hips, so if one goes up, the other goes down.
3. Take your measurements in “heads”
The front torso has roughly a “3-heads” length:
- 1 head from the chin to the base of the nipples
- 1 head from the nipples to the navel
- 1 head from the navel to the pubic arch
The torso is about 3-heads long
4. Know the back muscles
The human back holds 14 main muscles masses. On an average model, the back muscles typically won’t be visible, but a very athletic model may show more defined muscles.

The spine supports the head and the rib cage. On the spine, the 7th vertebrae is the limit between the neck and torso. Despite all these muscles in the back and shoulders, there are only a few muscles and bones that will be visible on an average back:
- The seventh vertebrae (it protrudes and is usually visible)
- The spinal column
- The rib cage on thinner models.
- The spine of the scapula (shoulder blade)
- The end of the lower latissimus dorsi muscles (see picture above)
5. Know the muscles at the front of the torso

Here is what you might see on an average model:
- The chest muscle (pectoris major)
- The sternum (flat bony plate situated between the ribs and between the chest muscles)
- The clavicle (think about it like an upside down coat hanger)

- The acromion process (it is the bony prominence on top of the shoulder, part of the scapula)

- The rib cage, on thinner models (we have 12 pairs of ribs).
- The navel, situated halfway on the abdomen.
- In very athletic person you might see the serratus anterior muscles that cover the ribcage and the rectus abdominus (this is more commonly known as a six pack).
- The muscles on the side are the external oblique (better known as “love handles”).
