line weight

How thick strokes

Line weight is the thickness or heaviness of a line in drawing, design, or typography.

Varying line weight creates visual hierarchy, depth, and emphasis: The architect used heavier line weight for walls and lighter weight for furniture.

In technical drawing, conventions assign specific weights to different elements—cut lines thicker than hidden lines, for instance.
