Scale custom fonts with UIFontMetrics

11 Sep 2022

It is possible to use custom fonts and for them to still work great with Dynamic Type. You need to define the default size and use UIFontMetrics to get the scaled font for each one of the styles you'd like to use.

Four labels with the text

Some of you have asked me how you can support what I do. This would really help, and would be hugely appreciated:

  • Find these posts useful? Share them at work, on social media, or with anyone that might find them interesting. Let's spread the word!

  • Check out any of my apps or games: Xarra!, RetroRapid!, or Mestre!.

    • A download and a review go a long way. They're free by default. On the App Store, ratings and reviews really help more people discover them.

    • Finding any of them useful? If so, and if you can afford it, purchasing lifetime access to all features or subscribing lets me buy the coffee that keeps me caffeinated. Caffeine keeps me going to maintain the apps, bring in new features that I hope you'll love, and keep writing.

What is the ideal distance between labels? It depends on styles for both of them and the dynamic type size, right? You wouldn't want to have the same distance for small and large text sizes. We can configure a standard distance between baselines.

Dynamic Type is a feature that lets a user change the font size (smaller or larger) of the whole system or a particular app. To support it, choose a preferred font based on one of the 11 supported text styles: Large title, heading, body...

If you are displaying something in two or more columns, you may want to change that to as little as one column when using some of the largest Dynamic Type settings to keep the text readable.
