Your dad holds his phone at arm's length, then pulls it close, then gives up and hands it to you: what does this say? Or your mom stops answering texts because she can't read them without her glasses, and the glasses are always in the other room. Small text is one of the quiet reasons older parents stop using their phones for anything but calls. The fix is already built into the iPhone. It takes about five minutes, and you can do it together on your next visit or walk them through it over the phone.

First, check which iOS your parent has

Apple moved some text settings in iOS 27, so the menu names depend on the version. To check, open Settings, tap General, then About, and look next to iOS Version, as Apple explains here.

The steps below are for iOS 27. On iOS 26 and earlier, anything listed under Appearance lives under Display & Brightness instead. Everything under Accessibility is in the same place on both.

Steps 1 to 3: bigger text, then bigger still, then bold

These three settings fix the problem for most parents. Do them in order and stop when your parent can read a text message comfortably. They change the text in Messages, Mail, Calendar, Notes, Contacts, Settings and other apps that follow the iPhone's text size, according to Apple's iPhone User Guide.

• Step 1, Text Size: open Settings, tap Appearance, tap Text Size, and drag the slider to the right. (On iOS 26: Settings > Display & Brightness > Text Size.)
• Step 2, Larger Accessibility Sizes: if the biggest regular size isn't enough, open Settings > Accessibility > Display & Text Size, tap Larger Text, turn on Larger Accessibility Sizes, and drag the slider further.
• Step 3, Bold Text: in Settings > Appearance, turn on Bold Text. Thicker letters are often easier to read than bigger ones. While you're in Accessibility > Display & Text Size, try Increase Contrast too.

Step 4: make everything bigger with Display Zoom

Text Size changes words. Display Zoom enlarges everything on the screen, including app icons, buttons and the keyboard, which helps a parent who mistaps or can't find small buttons. Open Settings > Appearance, tap Display Zoom, tap Larger Text, then confirm with Use Zoomed.

The trade-off is that fewer apps fit on each Home Screen page, so your parent may need to swipe more. If that bothers them, move their most-used apps to the first page and the rest into a folder. Apple warns that text that's too large can make buttons inside some apps hard to tap. If that happens, go back one size.

Make the text bigger. Then put Tiina on the same iPhone.

Some things a parent would rather ask about than squint at. On the same iPhone, they tap Call Tiina and read out what came in the mail, or share a photo of the small print, and she explains it in plain words, as many times as they need.

Step 5: fix the apps that ignore the setting

Some apps, including many banking, shopping and social media apps, don't follow the iPhone's text size. Here's how to handle them:

• Websites in Safari: tap the Page Menu button on the left side of the search field, tap Page Zoom, and tap the large A until the page is readable. Safari remembers the size for that website.
• One app needs a different size: open Settings > Accessibility > Per-App Settings, tap Add App, choose the app, then set its own text size.
• Quick changes on the fly: add the Text Size control to Control Center so your parent can adjust it from any app. Open Control Center, tap the plus sign in the top-left corner, tap Add a Control, then choose Text Size.
• Apps with their own settings: look inside the app for a text size or display option. Facebook, Kindle and most news apps have one.

Step 6: Zoom and Magnifier for everything else

Zoom magnifies any part of the screen. Turn it on in Settings > Accessibility > Zoom. To zoom in or out, your parent double-taps the screen with three fingers. It's powerful, but it confuses people who turn it on by accident, so show your parent how to turn it off the same way before you leave. Apple's Zoom instructions cover the rest.

Magnifier turns the iPhone into a magnifying glass for the real world: menus, pill bottles, the fine print on a bill. Open the Magnifier app, point the camera at the text and drag the slider to zoom. Your parent can freeze the image to read it up close. Add Magnifier to Control Center so it's one swipe away. Apple's Magnifier guide shows the extra controls.

Hover Typing helps a parent who can read fine but loses track while typing. Open Settings > Accessibility > Hover Text, tap Hover Typing and turn it on. As your parent types a text or an email, a larger copy of their words appears in a separate window. It doesn't need a mouse or keyboard, unlike the rest of the Hover Text feature.

Make it stick

If you're doing this over the phone, put your parent on speaker so they can see the screen while you talk. Have them read each menu name aloud before they tap it, and go one step at a time. When the text changes size, ask what they see. It's slower than doing it yourself, but they'll remember where the setting lives, and that's worth a lot the next time something changes.

Test the changes with real life, not the settings screen. Send your parent a two-line text and ask them to read it back to you. Ask them to open their email and their favorite website. If anything is still hard, go one size bigger or turn on Bold Text.

Then write the path on a card and tape it inside the phone case, so the next time a grandchild changes something by accident, your parent can put it back. For the next round of setup, these 10 iPhone settings to change for seniors cover sound, Siri and call blocking, and this plain guide to texting on iPhone helps once the words are big enough to read.

Finally, if reading has gotten harder quickly, book an eye exam. The National Institute on Aging points out that even small changes in eyesight are linked to a higher risk of falls, so it's worth a check, and new glasses can do more for reading than any setting.
