How Size It Up works

  1. Look. The solid blue shape is your yardstick — drawn at true scale, with its real size marked.
  2. Stretch. Drag across the board (or pinch, slide, use ← →) to resize the dashed white outline until it feels right.
  3. Measure! The real size snaps in as a yellow outline. Your accuracy earns up to ★★★.

Five shapes a day, the same for everyone. Can you get all 15 stars?
