When Apple first introduced retina (2×) displays, there was a spirited debate amongst iPhone app UI designers at the time about whether we should be designing at 1× or 2× resolution. Most UI designers back then were still using Photoshop and still creating raster source files, so this was a big decision: should we take advantage of the new retina screen by stuffing in more details? As retina screens became more commonplace, and UI designers began using newer vector tools like Sketch and Figma, the industry settled on 1× and we all collectively agreed that we weren’t going to use that extra detail, we were just going to let iOS scale our UI (but sharpen our text!) and not fuss about it any longer. But now everybody’s iPhone is 3× and the only apps that “fill” those extra pixels are games, essentially. App designers still design at 1× and 1pt strokes in Figma get expanded out to 3 pixels thick on our user’s screens and we’ve all just stopped caring, right? Well I started to care again, and I just want to say to other UI designers out there that you CAN experiment with UI elements with ⅓ pt inner strokes (hairline 1px at 3× retina) and 2⅔ pt blurs (8px) if you think it elevates the aesthetic. Lame industry standards that hold back craft should always be questioned
