Most iPhone and iPad apps designed decently with well take care of the font-size. But there are some apps which have font-sizes that are too small to be comfortably legible. Or sometimes, users have visual impairments that make it stressful to read the text in an app. Being able to increase the font-size comes as a big help in these cases.
Earlier, you could only alter the basic font-size in iPhone or iPad – this did not affect the font-size of the apps (specifically, the text contained in the apps). Now, Apple introduced two new toggles that increase the font-size of the text within apps, making them more readable.
The Text Size and the Larger Type settings change the font-size. All Apple stock apps get affected with every change you make in these settings, and all the third-party apps that support iOS’s Dynamic Type get affected too. Dynamic Type is a feature that allows users to toggle the font-size of compatible apps by tweaking the setting in the Settings app.
How to Increase the Text Size on iPhone or iPad From Display Settings
Step #1. Open Settings → Tap on Display & Brightness.
Step #2. Tap on Text Size.
Step #3. Drag the slider to the right to increase the size. An approximate representation of how the text would look like is shown over the slider.
Text Size is just one of the settings you can use to increase (or decrease) the font-size. There is one more accessibility setting that Apple put in the iPhone/iPad.
Change Font Size on iPhone or iPad From Accessibility
Step #1. Open Settings → Scroll down and tap on Accessibility.
On iOS 12 or Earlier, Open Settings → Tap on General → Scroll down and tap on Accessibility.
Step #2. Tap on Display & Text Size under VISION.
Step #3. Tap on Larger Text.
Step #4. Turn On the Switch next to Larger Accessibility Sizes and drag the slider.
Text Size and Larger Type can work in tandem and the result is you get to increase the font-size to very large sizes. Of course, sometimes too large a size can screw up the interface and the experience. But this feature is useful when the max-size in Text Size isn’t enough and you need to notch it up by a bit.
That’s all, mate!
