+When you're designing for mobile, it's important to remember that some people will need to change the size of the content
+to read it easily. There are so many ways to view content on mobile devices, from zooming in to orienting the screen differently, so a failure to design in a dynamic environment can lead to accessibility issues. There are different ways you can attend to this, whether you're writing an app for iOS or Android.
+
+## Considerations for iOS
+
+In iOS, users can only zoom in on specified areas. To allow them to resize the type, use [dynamic type](https://developer.apple.com/design/human-interface-guidelines/ios/visual-design/typography/#dynamic-type-sizes), which allows them to [resize the type](https://docs.google.com/spreadsheets/d/1B7UjuckBckAQtILeBCqoIUe3Ze3R8ow2KOQSM_JJI_w/edit#gid=0) in your app.
+
+If you manually limit how large your text scales it may cause issues for people who need a bigger font. 
+
+[Minimum font-size](https://uxdesign.cc/guide-for-designing-better-mobile-apps-typography-5796495ef86f) should be 17pt.
+
+## Considerations for Android
+Again, users can only zoom in on specified areas, so you'll need to use [scale-independent pixels](https://www.pixel-ruler.net/android-scale-independent-pixel) to determine the size of your text.
+
+There isn't a tool like Dynamic Type in Android, so you'll need to scale the text at different sizes yourself. Material design [has a resource](https://material.io/design/typography/the-type-system.html#type-scale) that makes a good starting point.
+
+[Minimum font-size](https://uxdesign.cc/guide-for-designing-better-mobile-apps-typography-5796495ef86f) should be 16sp:
+
+`android: textSize=16sp`
+
+You'll also want to remember to make your [content container scrollable](https://medium.com/mesmerhq/designing-accessible-text-for-android-variable-font-and-screen-sizes-392fd386aea5). If it's not, you'll just cut off the extra content when a person zooms in.
+
+## HTML
+
+In your HTML, make sure to use relative units for responsive design. 
+
+Note that a person's pinch-to-zoom capability will be frustrated on mobile < iOS10 if you add `maximum-scale=1.0` to the `meta` element.
