This ratio will help you calculate the border-radius for any size iOS style icon you're creating. 175438596Р”Р‡or simplicity, we can probably round this to about four or five decimal places. This ratio is calculated from Barnard's insight: 57 / 10 =. Therefore, to achieve the correct iOS-style border radius on any square icon you simply multiply the icon's size by what I'll call the iOS icon ratio. More specifically, when compared side-by-side, newer widgets have a rounder corner radius than legacy ones. Thus you can calculate the radius for any icon size using 10/57 x new size Kind words aside, one thing that really bugs me about the iOS 14 widget experience is that Apple appears to have made no effort to help legacy widgets conform to the newer design standard. According to Barnard, Apple calculates the border radius for icons starting at the 57px icon size (one can only assume that is because the size of icons on the original iPhone was 57px):Р”Р„pple starts with the 57px icon and a radius of 10 then scales up or down from there.

Well, thanks to David Barnard's post over at stackoverflow, we have insight into how the border radius for iOS icons is determined by Apple. So how do you actually get started creating an icon? Well, the amazing icon designer Michael Flarup has created a great iOS icon starter template with proper iOS-style proportions and radii.Р”В«ut what if you have to create an icon size that doesn't quite fall into Apple's predetermined sizes, say 175x175 pixels? How do you determine what size the border radius will be at any given size? However, for other other uses outside of iOS (such as a marketing site) you're going to have to create an icon with rounded edges yourself. Apple will do that for you automatically in all contexts, from iOS to the App Store. You don't actually have to create rounded corners for your icon artwork. 1024x1024 Recommended for iTunes Artwork.Apple details these requirements in their iOS Human Interface Guidelines: So you've got to create an icon for the iOS ecosystem, where do you start? You probably realized quickly you'll have to supply a couple different sizes for the various contexts in which the icon will be used.
