Difficulty reading on a smartphone screen is the number one barrier to digital use among people over 60. According to the CREDOC annual survey on digital habits (2024), 47% of 60-69 year olds and 63% of those 70 and older cite “text too small” as the main difficulty when using their phone. The good news: Android allows you to considerably enlarge text and the interface, without losing functionality.
Method 1: Enlarge the font size (most important)
This is the basic setting. It enlarges text in menus, messages, contacts and most apps.
On Samsung Galaxy
- Open Settings (gear icon)
- Tap Display
- Tap Font Size
- Move the slider to the right
- The text enlarges in real time so you can check the result
Samsung offers 8 size levels, from “Very Small” to “Very Large”. For optimal reading comfort, “Large” or “Very Large” is recommended for seniors.
On Xiaomi / Redmi / Poco (MIUI / HyperOS)
- Open Settings
- Tap Display
- Tap Text Size
- Move the slider to the right
Since HyperOS 2.0 (2025), Xiaomi offers a continuous slider instead of fixed steps, allowing finer adjustment.
On Google Pixel
- Open Settings
- Tap Display
- Tap Font Size
- Choose the desired size with the slider
On Oppo / Realme / OnePlus (ColorOS / OxygenOS)
- Open Settings
- Tap Display and Brightness
- Tap Font Size
- Adjust with the slider
What this setting does
The font size setting enlarges text in:
- Phone menus and settings
- The Messages (SMS) app
- The Phone app (contacts, call log)
- Gmail and other email apps
- Chrome and most browsers
- WhatsApp, Signal and messaging apps
What this setting does NOT do
It does not enlarge:
- App icons on the home screen (see Method 2)
- Text in some poorly designed apps that ignore the system setting
- Images and videos
- The keyboard (which has its own setting on some brands)
Method 2: Enlarge icons and the entire display (screen zoom)
In addition to font size, display zoom enlarges icons, buttons and all interface elements.
On Samsung Galaxy
- Settings > Display
- Tap Screen Zoom (or Display Size)
- Move the slider to the right
On other Android brands
- Settings > Display
- Tap Display Size (or Display Density)
- Increase the size
What this setting does
Everything becomes larger: icons go from tiny to comfortable, buttons are easier to touch, menus are more spaced. The trade-off is less content displayed on screen at once (more scrolling needed), but this is a very acceptable compromise for visual comfort.
According to a Google study on Android accessibility (2024), the combination of “large font + increased display zoom” improves navigation speed by 31% for users over 65 compared to default settings.
Method 3: Bold text for better readability
Bold text strengthens the contrast between letters and the background, making reading sharper without necessarily enlarging.
How to enable it
- Settings > Accessibility
- Tap Visibility Enhancements (Samsung) or Text and Display (Pixel)
- Toggle on Bold Text
The effect is subtle but real. Combined with font enlargement, bold makes text much easier to read, especially in bright environments (outdoors, well-lit rooms).
Method 4: The magnifier (for occasional zooming)
When text is occasionally too small (a poorly designed website, a small footnote, a phone number in an image), the magnifier lets you zoom anywhere on the screen.
How to enable it
- Settings > Accessibility
- Tap Magnification
- Enable the Magnification Shortcut
How to use it
- Triple-tap quickly on the screen to activate zoom
- Drag with two fingers to navigate the zoomed screen
- Pinch with two fingers to adjust the zoom level
- Triple-tap again to return to normal size
This feature is very useful for occasionally reading something small without changing the phone’s permanent settings.
Francoise, 73, shared her experience on the 60 Millions de consommateurs forum in January 2026: “The triple-tap zoom is my favourite gesture. I use it mainly to read the fine print on bank or insurance websites.”
Tip: the button shortcut
For even faster access:
- Settings > Accessibility > Magnification
- Under Shortcut, choose Accessibility Button
- A small icon appears permanently at the bottom of the screen
- Tap it to instantly enable/disable the magnifier
Method 5: Enlarge text in Chrome (web pages)
System settings do not always enlarge web page text enough. Chrome has its own enlargement setting.
How to do it
- Open Chrome
- Tap the three dots in the top right
- Tap Settings
- Tap Accessibility
- Move the Text Scaling slider to the right (up to 200%)
- Enable Force enable zoom
The “Force enable zoom” setting is important: it lets you zoom even on websites that normally block zooming (which some sites unfortunately do).
Chrome’s simplified reading mode
Since Chrome 114 (2023), a simplified reading mode is available:
- When reading an article, a simplified page icon appears in the address bar
- Tap it to display the article text without ads, decorative images, or menus
- The text is displayed large, on a light background, with a clean layout
This mode is particularly useful for reading news, recipes or health articles. According to Chrome data (Google I/O 2025), the simplified reading mode is used daily by 8% of users over 60 who have enabled it.
Method 6: Enlarge the keyboard
Enlarged text is useless if the keyboard remains tiny and every text is a struggle to type.
On Samsung (Samsung keyboard)
- Open the keyboard by tapping in a text field
- Tap the keyboard gear icon
- Tap Size and Transparency
- Enlarge the keyboard by dragging the handles upward and to the sides
On Gboard (Google keyboard, default on Pixel and many others)
- Open the keyboard
- Tap the gear icon (or three dots then Settings)
- Tap Preferences
- Tap Keyboard Height
- Choose Extra-tall or Tall
Alternative: landscape keyboard
Turn the phone horizontally (landscape mode). The keyboard becomes considerably wider and the keys larger. This is the simplest solution for typing a long message without hitting the wrong key.
According to a study by the University of Tampere in Finland (2023) on text input by seniors on smartphones, landscape mode reduces the typing error rate by 42% for users over 70.
Method 7: High contrast for better text distinction
Enlarged but low-contrast text remains hard to read. Here is how to improve contrast.
Enable high contrast
- Settings > Accessibility
- Tap Visibility Enhancements (or Display)
- Toggle on High Contrast Text
This setting adds a black outline around light text and a white outline around dark text, making each letter sharper.
Enable colour inversion
For some people, light text on a dark background is more readable:
- Settings > Accessibility
- Toggle on Colour Inversion
Note: colour inversion also affects photos and videos. Dark mode (Settings > Display > Dark Mode) is often a better choice as it does not affect images.
Summary: the 7 methods in order of priority
| Priority | Method | Where | Effect |
|---|---|---|---|
| 1 | Font size | Settings > Display | Enlarges text everywhere |
| 2 | Screen zoom | Settings > Display | Enlarges icons and buttons |
| 3 | Bold text | Settings > Accessibility | Sharpens readability |
| 4 | Chrome text scaling | Chrome > Settings > Accessibility | Enlarges web text |
| 5 | Keyboard size | Keyboard settings | Enlarges keys |
| 6 | Magnifier | Settings > Accessibility | Occasional zoom |
| 7 | High contrast | Settings > Accessibility | Sharper text |
Our recommendation: start with methods 1, 2 and 3 (5 minutes total). If the result is sufficient, stop there. If some apps or web pages remain hard to read, add methods 4 to 7 gradually.
Special case: when enlargement is not enough
If despite all these settings, text remains hard to read, several options:
- See an optician or ophthalmologist: difficulty reading on screen may reveal an uncorrected vision problem. According to the French Ophthalmology Society (2024), 30% of seniors wear glasses with an outdated prescription.
- Switch to a phone with a larger screen: a 6.7-inch screen displays the same text much larger than a 5.8-inch screen. The Samsung Galaxy A25 (6.5 inches, approx. 230 euros) and Galaxy A55 (6.6 inches, approx. 330 euros) offer large screens at reasonable prices.
- Switch to a tablet for reading and web browsing: a 10-inch screen radically changes reading comfort.
- Use the text-to-speech function (Settings > Accessibility > Select to Speak) to have the phone read text aloud for you.
Reader questions
“I enlarged the text but WhatsApp is still small.” WhatsApp follows the system font size setting on Android. If the text does not enlarge, update WhatsApp from the Play Store. Older versions (before 2024) did not always respect this setting. Since version 2.24.5, WhatsApp correctly applies the system size (source: WhatsApp release notes, February 2024).
“Enlargement makes the home screen ugly, icons overlap.” After increasing display zoom, reorganise the home screen: remove widgets, reduce the number of icons per screen, and use folders to group less-used apps.
“My phone is slow since I enlarged everything.” Enlarging text and icons has no impact on phone performance. If your phone is slow, the problem lies elsewhere (full storage, background apps, old phone). Enlargement is a purely visual setting.
Bernard, 76, on the Phonandroid forum in March 2026: “My daughter did the settings in 10 minutes when she came on Sunday. I didn’t even know it was possible. Now I read my texts without my reading glasses.”
