Your mother holds the phone at arm’s length, tilts her chin down to look through the bottom of her glasses, and reads a text message one word at a time. Someone showed her how to pinch-zoom in the browser once, so the browser is fine. Everything else — messages, the bank app, the medical portal — is still set at a size chosen by a designer in his thirties with excellent eyesight. There is one setting that changes all of it, and it is three screens deep in a menu called Accessibility, which nobody opens because nobody thinks the word applies to them.
iPhone: the one screen that changes everything
- Open Settings.
- Tap Accessibility.
- Tap Display & Text Size.
- Tap Larger Text.
- Turn on Larger Accessibility Sizes at the top. This is the switch people miss — without it, the slider stops well short of where it can go.
- Drag the slider. The sample text at the top changes as you move it.
Then back out one screen and switch on Bold Text. That single toggle does more for legibility than two notches of size.
Also on that screen and worth trying:
- Button Shapes — puts underlines under things that are tappable. Resolves the modern design problem where a button and a label look identical.
- Increase Contrast — darkens grey-on-grey text, which is the other half of why things are hard to read.
- Reduce Transparency — kills the frosted-glass effect behind menus that puts text over a blur.
Android: two settings, and both matter
Android splits it in a way that confuses people, because changing one and not the other gives half a result.
- Open Settings.
- Tap Display (on Samsung: Display, then Font size and style).
- Font size — makes letters bigger, leaves the layout alone.
- Display size — makes everything bigger, including buttons, icons and spacing.
Most people need both nudged up. Font size alone gives you large text crammed into small boxes.
Also under Settings → Accessibility:
- Bold text — same reasoning as iPhone.
- High contrast text — adds an outline behind letters on difficult backgrounds.
- Magnification — triple-tap the screen to zoom anywhere, including places that refuse to scale.
The apps that ignore all of it
Some apps are built so they do not follow the system setting. Banking apps are the worst offenders. Three ways around it:
1. Zoom the whole screen. This works everywhere, in every app, with no cooperation needed.
- iPhone: Settings → Accessibility → Zoom. Turn it on. Then three fingers, double tap, to zoom in and out anywhere. Three fingers double-tap and drag changes the level.
- Android: Settings → Accessibility → Magnification. Choose the shortcut, then triple-tap to zoom.
2. Have it read to you. Not a screen reader for the blind — a simple “read this part out loud”.
- iPhone: Settings → Accessibility → Spoken Content → Speak Screen. Then swipe down with two fingers from the top and it reads the page.
- Android: Settings → Accessibility → Select to Speak. Tap the icon, then tap any text.
3. Landscape. Turning the phone sideways gives the text more width and fewer line breaks. Make sure rotation is not locked — the padlock-with-arrow icon in Control Centre on iPhone, or Quick Settings on Android.
The computer, in one line each
- Windows: Settings → System → Display → Scale. Set it to 125 or 150 percent. For text only, Settings → Accessibility → Text size.
- Mac: System Settings → Displays → choose a Larger Text resolution. Or per-app, Cmd and +.
- Any web browser: Ctrl and + (Cmd and + on Mac). It remembers the setting per website, which means you set it once on the bank’s site and it stays.
- A whole webpage that is still hard to read: Reader mode. The small page-shaped icon in the address bar strips out the layout and leaves the article in plain large type. On iPhone it is in the “AA” menu in Safari.
Setting it up for someone else
If you are doing this for a parent, two things make it stick:
Go one step further than they say is enough. People under-ask, because asking feels like admitting something. Set it one notch larger than the point where they say “that’s fine”, and ask again in a week.
Show them how to undo it. Someone who knows they can put it back will let you change it. Walk them to the slider, let them move it themselves once, and leave it where they put it.
