Circles, Squares, and Shapes Inside Shapes

Every shape in art can contain — or be contained by — any other shape. This relationship is the secret to placing forms confidently on the page and in three-dimensional space.

KEY CONCEPTS

A circle fits inside a square — finding that center reveals perspective
A square has four corners = the number 4 = the chest/torso
A circle takes five defining points = the number 5 = the hand
Every body form can be "boxed in" — the box reveals the angle in space
Tilt the square slightly and the inscribed circle becomes an ellipse — that IS perspective

Draw a square. Connect corner to corner with an X. The center of that X is the center of the square — and it is also the center of a circle inscribed within that square. You have just found the fundamental relationship that governs all of your forms.

Now take that square and imagine it as a box in space — a slightly turned rectangular prism. One face is larger (closer to you), the other is smaller (farther away). That difference in size is perspective. Your figure exists inside a space exactly like this.

In our number system: a square has four sides = 4 = the chest. A circle takes five defining points = 5 = the hand. These are not coincidences — they are memory hooks that will help you recall the right form at the right moment, instantly, without reference material.

TRY THIS — 10 MINUTESDraw a square. Inscribe a circle inside it — touching all four sides. Now tilt the square slightly (make one side shorter, one side taller). Watch the circle become an ellipse. Draw that ellipse. You have just learned the core of perspective drawing from two shapes.
