Step-by-Step Instructions

Step 1: Sketching the Skull Shape

Pencil sketch of the basic rounded skull shape for Sans from Undertale.

Start by drawing the skull. Use two overlapping curved lines to create a slightly pinched, rounded shape. Teacher's Tip: Keep your pencil pressure light so you can easily erase the overlapping lines later to refine the jawline.

Step 2: Adding the Eye Sockets

Drawing the eye sockets and pupils for the Sans character.

Draw two irregular, rounded shapes for the eye sockets. Add a small, shaded circle inside each to represent his pupils. Teacher's Tip: Make the eyes slightly asymmetrical to give him that classic, mischievous Sans expression.

Step 3: Defining the Nose and Grin

Detailed view of adding the nose and the wide, toothy grin of Sans.

Add a small, shaded triangle for the nose. For the mouth, draw two long, wide-curved lines connected at the ends, then add vertical lines to create the teeth. Teacher's Tip: Ensure the teeth are evenly spaced to keep his smile looking clean and intentional.

Step 4: Sketching the Hoodie and Neck

Adding the neck and the collar of the hoodie to the character sketch.

Use curved lines to outline the neck area and the opening of his signature hoodie. Teacher's Tip: Focus on the folds of the fabric near the neck to give the drawing a sense of depth and realism.

Step 5: Drawing the Arms and Jacket

Sketching the arms tucked into pockets and the main body of the jacket.

Draw the arms tucked into the jacket pockets using simple curved lines. Outline the rectangular shape of the jacket body. Teacher's Tip: Keep the lines for the arms slightly rounded to show he is relaxed with his hands in his pockets.

Step 6: Refining the Jacket Details

Adding final structural lines to the jacket for a finished look.

Add final details to the jacket, including the hem and elbow bends. Teacher's Tip: Use a slightly darker line for the jacket edges to make the character pop against the background.

Step 7: Sketching the Pants

Drawing the baggy pants with vertical stripe details.

Draw the pants using simple curved lines and add vertical bands to indicate the stripes. Teacher's Tip: Keep the pant legs loose and baggy to match the character's casual style.

Step 8: Adding the First Slipper

Drawing the first slipper at the base of the leg.

Extend the leg lines downward and draw the slipper shape at the bottom. Teacher's Tip: Slippers are rounded and soft, so avoid sharp corners when drawing the toe area.

Step 9: Completing the Second Slipper

Adding the second slipper to complete the full-body sketch.

Mirror the first slipper on the other leg to complete the lower body. Teacher's Tip: Check that both slippers are at the same height so your character looks balanced.

Step 10: Adding Color

The final colored drawing of Sans from Undertale.

Bring your drawing to life with color! Use blue for the jacket, white for the skull, and black for the pants stripes. Teacher's Tip: Use light, even strokes with your colored pencils to keep the colors smooth and vibrant.
