Designing iOS & Android system icons for your mobile app
Jamison Hill

Great article, very helpful!

Question: I struggle trying to maintain visual proportions of my icons (within a set). I try to size each of them within a pre-proportioned box. As a result, I end up messing up say, a file icon as I try to match it up with a battery icon. How do I achieve harmony while maintaining symmetry?

Thanks for reading!
