How To Draw A Rib Cage easy with this how-to video and step-by-step drawing instructions. Easy drawing tutorial for beginners and everyone.
Please see the drawing tutorial in the video below
You can refer to the simple step-by-step drawing guide below
Step 1
This rib tutorial will have some intricate details and angles to draw, so we’ll take it slow and break it down into smaller steps.
Now, we’ll start with the base of the rib cage. Use some curves that start near the center end of the rib cage and stretch them outward as they appear in the reference image.
We will then stretch some long, thin and curved shapes outward and then back to form the ribs of the rib cage.
They will be slightly smaller at the base, but they will get larger as you move upwards. Once you’ve drawn these ribs, we can start drawing the next part of the rib cage.
Step 2 – Now draw some more ribs for the frame
Continuing with this rib drawing, we will add more ribs to it. First, use some more curved lines to draw the central structures, like the branch from which the ribs will extend.
Once that’s done, we’ll draw some more ribs extending upwards. For the final step, these ribs will get a little longer as you move up.
If not, you can use the same method for these ribs that you used for the previous ribs. When you are ready, we can continue to step 3 of the tutorial.
Step 3 – Next, draw some more ribs and add to the center structure
In this third step of the rib cage tutorial, we’ll begin to draw the central structure of the rib cage, and this part is called the sternum.
You’ve started the base of the sternum, and in this section we’re going to use some bumpy vertical lines for its edges. Once they have been drawn, the next step will be to draw some more ribs extending away from the breastbone.
Just like you did for the previous ribs, these ribs will consist of two parts, one each, and we will extend two sections from each side of the sternum.
We will then finalize the contours for the front of the rib cage in the next step.
Step 4 – Draw the Rest of the Front Side of the Rib Frame
Before you add the final touches and colors to your skeleton drawing, we will finalize the contours for the front of the frame.
First, you can finish off the top of the sternum using some lines similar to the ones you used.
Then we will draw another part on top of the sternum. This part is called the sump, and as in the reference image, it’s shaped a bit like a short, squat T-shape.
On this part you can then plot the top of the nominal column.
Once we’ve finished drawing, we’ll add some more ribs. There will be two from the sternum and two more from the trachea, and they will also get smaller as you go higher.
Step 5 – Add Final Strokes to Your Rib Drawing
It’s almost time for the final step of this rib tutorial, but first, we’ll draw the veins at the back of the rib cage.
Fortunately, these will be easier to draw than the first ones. To draw these we will use some black cubes in between the ribs at the front of the cage.
The reference image will also show you how you can position them.
After these ribs are drawn, you are ready for the final step! Before continuing, you can also add to the drawing, perhaps by adding some more bones that will be attached to the rib cage.
Step 6 – Complete your rib drawing with some colors
People often imagine bones to be pure white, but this is not true for real bones. For our example of this rib drawing, we finished it off with some more realistic colors.
These colors include some muted tones of yellow and brown, as shown in our reference image. You can use this as a guide if you want some realistically similar colors, but you can also change the colors if you want!
When coloring, you may want to use a medium that allows for precision, as there are a number of small parts to color.
Crayons, pencils, or a fine-tipped paintbrush would be great for you to try!
