What Is a Croqui?
A croqui is a simple sketch of the human body used in fashion illustration — usually drawn as a fast, expressive figure that shows off garment design and style. It functions as a template for illustrating clothes: rather than designing directly onto a blank page, a designer sketches garments onto a croqui, which already has the proportions of a human body worked out in advance.
This matters practically, not just artistically. When designing a garment, croquis help a designer understand how a dress will actually look on a human figure, and using them consistently helps develop a real fashion sense and sense of proportion over time — skills that transfer directly into how convincingly a final design reads on an actual body.
The 8-Head Theory
The basic proportion of the human body in fashion illustration is explained using the 8-head theory: from head to toe, the body’s height is divided into 8 equal parts, each equal to the height of the head. Fashion figures are drawn based on this proportion, using the head as a built-in unit of measurement for the rest of the body.
In practice, this means a designer picks a single ‘head unit’ length — for example, 1¼ inch — and then divides the whole figure’s height into 8 equal parts vertically, using that unit. Horizontal guideline divisions are also marked at these levels, giving the designer a consistent grid for placing shoulders, waist, hips, and other key body landmarksaccurately, every time.
8-Head vs 10-Head Figures
To make fashion drawings more attractive and dynamic, both 8-head and 10-head fashion figures are used in practice. The 10-head figure is especially used for more stylised fashion illustration — elongating the figure beyond realistic human proportions to create the more dramatic, elegant look associated with fashion sketches (as opposed to anatomically accurate figure drawing, where 8 heads is the standard).
Approximate Body-Part Measurements
Once the head unit and overall height are set, a croqui also relies on a set of approximate width measurements for different parts of the body, keeping the figure’s proportions consistent and believable:
| Body Part | Approximate Width (in head units) |
| Shoulder width | About 1 inch |
| Waist | About ½ inch |
| Hip | About ¾ inch |
| Ankle width | About ¼ inch |
| Foot width | About ½ inch |
The Croqui in Practice
In a typical fashion illustration course, four standard croqui variations are practised: the 8-head blocked figure (basic proportional blocks, no detail), the 8-head fleshed croqui (the blocked figure refined into a more realistic outline), and the corresponding 10-head blocked figure and 10-head fleshed figure for stylised illustration work. Moving from ‘blocked’ to ‘fleshed’ is really the same progression as moving from a rough proportion grid to a finished, illustration-ready figure — the blocked version establishes where everything goes, and the fleshed version is what a designer actually draws garments onto.
