We provide a practical guide to five ways to measure pixels on a Mac: the built-in **Cmd+Shift+4** crosshair, Digital Color Meter, free Shottr, paid PixelSnap, and xScope. It also explains Chrome DevTools, includes a complete JavaScript snippet for measuring distances between two elements, and clarifies Retina logical points versus physical pixels. The quick reference lists PixelSnap at **$39 one-time**, xScope at **$49.99 one-time**, and the built-in and Shottr options as free. Retina guidance includes the 2x relationship between logical points and physical pixels and steps for checking a display’s scale factor.
