How to Draw A Rib Cage. The human body comprises many different parts that together form a complete structure. One of the most influential elements of the human body is the skeleton.

Made up of many different bone structures, it gives the body rigidity and protects important organs.
The rib cage is one of the numerous complicated and important structures and helps protect parts like the heart and lungs. Due to its complex structure, it can be difficult to learn to draw a rib cage.
However, that is the purpose of this guide, and we will show you how to do it easily!
We hope you enjoy our step-by-step tutorial on how to draw a rib cage, and we also hope you find it fun and useful.
How to Draw A Rib Cage
Step 1
This tutorial on how to draw a rib cage will have some tricky details and angles, so we will take things slowly and break them down into smaller steps.
First, let’s start with the base of the rib cage. Use some curved lines starting near the bottom of the center of the rib cage and extending outward as they appear in the reference image.
Next, we’ll expand several long, thin, curved shapes outwards to form the rib cage ribs.
These are slightly smaller at the base but grow larger over time. With these ribs drawn, we can start drawing the next section of the rib cage.
Step 2
We’ll add even more ribs as we continue with this rib cage drawing. First, use a few more curved lines to draw the central branch-like structures from which the ribs extend.
After drawing, we draw more ribs that extend upwards. As with the last step, these ribs stretch slightly as you stand up.
Otherwise, you can use the same method for these ribs that you used for the previous ones. When you’re ready, we can move to step 3 of the guide.
Step 3
In this third step of our tutorial on how to draw a rib cage, we’ll start by drawing the central structure of the rib cage, called the sternum.
You’ve already started at the base of the sternum, and in this part, we will use some jagged vertical lines for its sides. After drawing, the next step is to draw more ribs extending from the sternum.
As you did with the previous ribs, these will be in two sections each, and we will extend two from each side of the sternum.
The next step is to complete the outline for the front of the rib cage.
Step 4
Before we add the finishing touches and color to the rib cage design, we will finish the final outline for the front of the rib cage.
First, you can refine the top of the sternum with a few lines similar to the ones you used.
Next, we draw another section above the sternum. This part is called the handlebar and is shaped like a short, squat T, as shown in the reference image.
You can then draw the top of the seed column above this part.
After drawing, we’ll add more ribs. There will be two coming out of the sternum and then two more coming out of the manubrium, and they, too, will get smaller as they go up.
Step 5
It’s almost time for the final step of this tutorial on how to draw a rib cage, but first, we’ll draw the ribs on the back of the rib cage.
Luckily these are easier to draw than the first ones. To draw them, we’ll use solid black shapes between the ribs on the front of the cage.
The reference image also shows you how to position them.
Once those back ribs are drawn, you’re ready for the final step! Before proceeding, you could also add something to the design, adding more bones to attach to the rib cage.
Step 6
People often imagine bones as pure white, but real bones are not. We topped it off with more realistic colors for our example of this rib cage design.
These colors include muffled screams and browns, as our reference image shows. You can use this as a guide if you want equally realistic colors, but feel free to change the colors if you’d like!
Using a medium that allows precision is recommended when staining since there are some small parts to stain. Colored pencils, pencils, or fine-tipped brushes would be great to try!
