Measure your hand-span, foot, cubit (elbow to fingertip), pace. Record them. Now measure your room in YOUR units.
Your personal toolkit
- Hand-span — between thumb tip and pinky tip when stretched
- Foot — heel to toe
- Cubit — elbow to fingertip
- Pace — one comfortable step
Your pace is roughly your height ÷ 2.4. Pacing across a room gives you a fast distance estimate without any tools.
