Matching Drop Shadows Across CSS, Android, iOS, Figma, and Sketch
Shadows vary across platforms (CSS, Android, iOS) despite using same values. CSS shadows match well between Safari, Firefox, and Chrome, and also with Sketch and Figma.

CSS to iOS needs a 0.5× scale, while Android requires more complex adjustments based on rendering differences. The article provides formulas for converting shadow blur radii between platforms to achieve a good match.
