Tap Text Size
It is below Liquid Glass on the Appearance page, with Bold Text right under it.

Drag the slider to the right
Each step to the right makes the text a little bigger. On our iPhone 17e the slider sat in the middle. Under it there is a link, More in Accessibility Settings… The note at the top of the page reads: Apps that support Dynamic Type will adjust to your preferred reading size below.

Switch on Bold Text if you like
Go back one page. Bold Text is the switch below Text Size. On our iPhone 17e it was off. The same switch is also at the top of Accessibility, Display & Text Size. Thicker letters are easier to read for many people.

Need it bigger still? Open Accessibility, Display & Text Size
Go to Settings, Accessibility and tap Display & Text Size, then Larger Text. This path is the same on iOS 26 and iOS 27. On our iPhone 17e Larger Text showed Off.

Switch on Larger Accessibility Sizes
With the switch at the top of Larger Text on, the slider gains more steps; Apple calls them additional text sizes. On our iPhone 17e Larger Accessibility Sizes was off.
