Understanding the Basic Building Blocks of Lips
Before picking up a pencil, it helps to understand what shapes make up a human lip. Lips are not just random curves—they follow predictable geometric patterns that artists use as foundations. The basic structure of lips can be broken down into several fundamental shapes: circles, ovals, triangles, and rectangles.

The upper lip typically resembles two rounded hills or bumps meeting in the middle. Artists often visualize this as two half-circles or ovals positioned side by side. The lower lip is generally larger and rounder, frequently drawn as a single oval or ellipse. The dividing line between the upper and lower lip, called the lip line, creates a horizontal reference point that helps with proportion.
When you look at lips from a front view, you'll notice that the upper lip has more defined angles and points, particularly at the peaks where the two halves meet. The lower lip is smoother and more curved overall. This difference in angularity is crucial to capturing realistic lip shapes. Additionally, lips have thickness—they're not flat lines but have depth and volume that artists represent through shading and shape placement.
The basic proportion to remember: the lower lip is typically about one-third larger in volume than the upper lip in most adult faces. This relationship holds true across different ethnicities, though individual variation exists. Understanding these proportions prevents common beginner mistakes like drawing lips that appear unbalanced or poorly positioned on the face.
Practical takeaway: Before your next drawing session, spend time observing lips in photographs or mirrors. Mentally outline the geometric shapes you see. Notice how the upper lip has two distinct bumps and the lower lip appears more rounded. This observation practice trains your eye to recognize the basic shapes automatically when you begin drawing.
Drawing the Upper Lip Using the Two-Circle Method
The two-circle method is one of the most reliable techniques for beginners learning to draw upper lips. This approach breaks the upper lip into two equal or nearly equal circles or ovals positioned horizontally next to each other. To start, lightly sketch a horizontal line where you want the upper lip to sit. This line serves as your guide and represents the middle division point between the two halves of the upper lip.

Draw two circles or ovals along this line, positioning them so they overlap slightly at the center point. The overlap is important because it creates the central peak, or philtrum area, which is a characteristic feature of upper lips. Each circle should be roughly the same size, though in some face types, one side may be slightly larger than the other. Make these circles light and loose at first—you're building a framework, not creating the final product.
Once your two circles are in place, you'll refine the shape by connecting them smoothly. The outer edges of each circle become the outer contours of the upper lip. The inner edges, where the circles overlap, create the central peak that points upward. Some artists add a small V-shape or point at this center to emphasize the natural ridge that appears on many upper lips. The bottom edge of your circles forms the upper lip's bottom border, which meets the lower lip.
Common refinements include softening the sharp points where circles meet, adding subtle curves rather than hard angles, and adjusting the width based on what you observe. The space between the two circles' peaks and the lower lip line below them creates negative space that you'll eventually shade or define as the mouth's opening.
Practical takeaway: Practice drawing five upper lips using only two circles per lip. Don't worry about perfect symmetry or realistic proportions yet. Focus on consistent placement of the circles and clear connection points. This repetition builds muscle memory and makes the technique automatic when you move to more complex drawings.
Creating the Lower Lip With Simple Oval Shapes
The lower lip is generally more straightforward to draw than the upper lip because it follows a simpler, more unified shape. The foundation for a lower lip is typically one large oval or ellipse positioned below the upper lip. This oval should be wider than it is tall, reflecting the natural width and proportions of lower lips in most faces.

Begin by drawing a horizontal oval shape that aligns with the bottom edge of your upper lip circles. The width of this oval should roughly match the combined width of your two upper lip circles, though it may extend slightly beyond them depending on the face you're drawing. The height of the oval—the distance from top to bottom—should be noticeably less than its width, creating that characteristic flattened appearance of lower lips.
The top edge of your lower lip oval connects directly to the bottom of your upper lip circles, with perhaps a tiny gap to represent the mouth line where the two lips meet. The bottom edge of the oval creates the outer contour of the lower lip. In many lip drawings, the bottom edge isn't perfectly curved but has a slight indentation or curve that reflects the natural shape where the lower lip turns under at its edge.
To add dimension and realism, consider dividing the lower lip oval into two halves with a very light vertical line down the center. This center line helps you shade more naturally later and reflects the actual subtle anatomy of lower lips. Some lower lips have a central fullness that peaks slightly in the middle, which this line helps you represent. The sides of the lower lip slope slightly downward from this central peak.
Practical takeaway: Draw ten lower lips of varying widths using the single oval method. Experiment with different oval proportions—try some that are quite wide and flat, and others that are slightly taller. This variation helps you understand how oval proportions affect the overall appearance of the lip and prepares you to draw different mouth shapes.
Combining Shapes and Adding the Mouth Opening
Now that you understand how to draw the upper lip with two circles and the lower lip with an oval, the next step is combining these shapes into a complete mouth. The mouth opening—the space between the upper and lower lips—is crucial to creating a realistic appearance. This space is not merely empty; it's a distinct shape that requires careful consideration.

The mouth opening is typically a horizontal ellipse or rounded rectangle positioned between your upper lip circles and lower lip oval. The width of this opening should match the width of your upper and lower lips. The height is much smaller, creating a thin, horizontal shape. In a closed-mouth smile, this opening is minimal or even invisible. In an open-mouth drawing, this opening becomes much larger and more prominent.
The mouth opening's edges should follow the contour of your lip shapes. The top edge follows the bottom contour of your upper lip circles. The bottom edge follows the top contour of your lower lip oval. These edges are rarely perfectly straight; they have subtle curves that reflect the three-dimensional form of the lips. At the corners of the mouth—where the upper and lower lips meet on the sides—create a clear point or junction. This corner point is important for defining the extent of the mouth.
When combining all shapes, step back and check proportions. Your upper lip should not be larger than your lower lip, and the mouth opening should feel balanced between them. The corners of the mouth should align vertically with the centers of your eye pupils, which is a helpful rule for facial proportions. If something looks off, adjust your shapes before adding details. It's much easier to modify basic shapes than to fix a complete drawing.
Practical takeaway: Draw five complete mouths using the combined shapes method: two circles for the upper lip, one oval for the lower lip, and one small ellipse for the mouth opening. Practice both slightly smiling mouths (with minimal mouth opening) and more open-mouthed expressions (with larger mouth openings). Notice how changing only the mouth opening's size dramatically changes the expression.
Adding Shading and Dimension to Flat Shapes
Basic shapes are your foundation, but they appear flat and lifeless until you add shading. Shading is what transforms simple circles and ovals into three-dimensional, realistic-looking lips. Understanding where light and shadow naturally fall on lips helps you shade effectively. Typically, light hits the upper lip's outer surface, creating a bright area. The area where the upper lip turns inward toward the mouth is darker. The lower lip is usually somewhat darker overall because it's positioned lower and receives less direct light.

Begin shading by identifying your light source. If light comes from above and slightly to the left, the upper lip's upper surface gets the most light, appearing lighter. The underside of the lower lip and the shadowed areas between and under the lips appear darker. Use a technique called hatching or cross-hatching
