There are a few stock Apple apps that we avoid, but Safari isn't one of them. From its streamlined look to its auto ad-blocking, the Safari web browser for iPhone is one of Apple's most polished default mobile apps.

Depending on which iPhone you have, you may find the volume or size of text on the screen is too much, too little, too big or too small. The iPhone SE is a masterclass in miniature iOS, but with a 4in display you can't fit much text on there.

On the other hand, the ginormous tall 6.5in screen on the iPhone 11 Pro Max is poised ready to show you reams of text from websites. But because it is dependent on each website as to how large text will display, you might find that you want to change it.

To better tweak your iPhone Safari reading experience to suit you, you can adjust the text size of individual websites or for all of Safari. From there, you can then monitor and maintain those settings for all mobile sites, or for some select ones. Here's how.

Changing the text size on Safari for iPhone

The first way is simple, so dive right in.

  1. Open Safari and navigate to the desired website.
  2. When it has loaded, Safari will display with an 'aA' icon at the top left of the display. Tap this to see a menu.
  3. You can then tap the small 'A' to reduce text size or the large 'A' to increase it.

The text size will change each time to show you the changed web page. Just tap away from the menu when you're happy with the size.

Your iPhone will cleverly remember this preferred text size for the domain you're visiting - so in this case, our iPhone will keep macworld.co.uk at 85% every time we visit it, no matter the exact page.

This is handy if one or more of your frequently visited websites on Safari has a text size you find too big or too small on your iPhone. Adjust away.

Changing the text size for all sites

If you'd rather change the default text size for all sites you visit using Safari, here is how.
