Hand-Drawn Ruler Sketch - Measurement Concept Illustration #112899 (License: Personal Use)

This black-and-white ink sketch depicts a stylized ruler with irregular tick marks and handwritten numerals (12, 24, 30) along its edges. A small circle is centered near the bottom, possibly indicating a pivot point or hole. The drawing conveys an informal, conceptual approach to measurement rather than precision instrumentation.

Used in educational blogs, design thinking resources, or UX wireframing guides to symbolize estimation, scaling, or early-stage ideation where exact measurements aren’t yet finalized.
