![]() This means that if UX and design quality matters, you can't just scale down an icon and expect it to be as clear as the original one. Those rules are actually followed in Windows XP icons. On a smaller icon, there is no enough place to draw a pencil in a way it does not cover the notepad, and is recognized as a pencil at the same time. For example a large icon of a notepad can feature a notepad with a pencil. The number of objects must decrease when the size decreases. The object may be rotated to be in perspective when the icon is large. Other factors than the object detail level must be taken in account:Ī shadow, for example, is nice to have on a 64×64 icon, but the same shadow will look stupid on a 16×16 favicon. Actually looks like PF-19686592 calculator for me. The icon on the right, the resized version of the large one, is completely meaningless: it might be a PDA, or a silver box, or anything else. ![]() The icon on the left, used by Windows 7, is pretty clear, despite the low resolution. Let's see what happens when we go to an even smaller scale: On the right, I believe it's a strangely shaped PDA with a large screen, two buttons at the bottom of the screen and one large button at the very bottom. Now, compare, side by side, the downscaled icon on the left, and the icon I resized in Photoshop from the larger one: I take the graphically excellent keyboard icon used in Windows 7: For a 16×16 icon, four keys is enough: either you draw four and users understand that those are keys, or you draw more and everything becomes flat. For example, a large icon of a keyboard may contain every key of the keyboard. Those details, which are nice on a 128×128 icon, would be disturbing on a 32×32 icon instead of helping visually identify the icon, they will do the opposite. When you create an asset that includes your adjustments as padding around an interface icon (as shown below on the right), you can optically center the icon by geometrically centering the asset.The answer applies both to vector and to rasterized icons. In such cases, you can slightly adjust the position of the icon until it’s optically centered. For example, the download icon shown below has more visual weight on the bottom than on the top, which can make it look too low if it’s geometrically centered.Īn asymmetric icon can look off center even though it’s not. Some icons - especially asymmetric ones - can look unbalanced when you center them geometrically instead of optically. If necessary, add padding to a custom interface icon to achieve optical alignment. Unless you want to emphasize either the icons or the text, using the same weight for both gives your content a consistent appearance and level of emphasis. In general, match the weights of interface icons and adjacent text. and use the same stroke weight in every icon. To help achieve visual consistency, adjust individual icon sizes as necessary. Depending on the visual weight of an icon, you may need to adjust its dimensions to ensure that it appears visually consistent with other icons. Whether you use only custom icons or mix custom and system-provided ones, all interface icons in your app should use a consistent size, level of detail, stroke thickness (or weight), and perspective. Maintain visual consistency across all interface icons in your app. In general, icons work best when they use familiar visual metaphors that are directly related to the actions they initiate or content they represent. Strive for a simple, universal design that most people will recognize quickly. Too many details can make an interface icon confusing or unreadable. Best practicesĬreate a recognizable, highly simplified design. Both interface icons and symbols use black and clear colors to define their shapes the system can apply other colors to the black areas in each image. You can design interface icons - also called glyphs or template images - or you can choose symbols from the SF Symbols app, using them as-is or customizing them to suit your needs. ![]() Unlike app icons, which can use rich visual details like shading, texturing, and highlighting to evoke the app’s personality, an interface icon typically uses streamlined shapes and touches of color to communicate a straightforward idea. An effective icon is a graphic asset that expresses a single concept in ways people instantly understand.Īpps and games use a variety of simple icons to help people understand the items, actions, and modes they can choose.
