How to Make Text and Icons Bigger on Your Phone in 2026

Key Points:

• The easiest way to make text and icons bigger on a smartphone is to go through the display options in your mobile device's settings menu, which is universal.
• You can independently scale the text and UI elements by utilising Display Zoom / Display size, whether you're on iOS or Android.
• If you only want an on-demand magnifiying option, both iPhones and Android have dedicated accessibility options with a three-finger tap and triple tap for iOS and Android.

Learning how to make text and icons bigger on a smartphone is one of the best ways to properly utilise your Talkmobile SIM-Only plan, particularly if you're using one of the best smartphones for seniors. You may need glasses when reading off the screen, or if you just want a quick and easy way to scan images and fine print, we're going through all the core methods, how they work, how to use them, and some viable alternatives on both iOS and Android devices available in 2026 further down the page.

The fastest and easiest way to make text and icons bigger on a smartphone is to go through the dedicated settings menu for both iOS and Android devices. It takes a couple of seconds and doesn't need to be adjusted once it's set up. Here's how to do it for both handset types:

• For iPhone: Go to Settings > Display & Brightness > Text Size and drag the slider to your desired size. You can also go for a larger-than-maximum font by heading to Settings > Accessibility > Display & Text Size > Larger Text and then enabling the "Larger Accessibility Sizes" option, if you need the biggest possible font available.
• For Android: Head to Settings > Display > Font size (sometimes called Settings > Accessibility > Text and display > Font size), and use the slider to scale things up to where you want them to be. You also have the option to make text bold, which can make the font easier to read when scaled, too.

As well as the text, you can make UI elements on Android and iOS devices larger as well from a similar menu. This can alter apps, control buttons, and other interactive elements on-screen, which can get bigger, separate from just the font size available. Here's what you need to do:

• For iPhone: Go to Settings > Display & Brightness, scroll down to Display Zoom, choose the Larger Text option and tap Done. This will re-scale the entire system layout.
• For Android: Go to Settings > Display > Display size (sometimes called Settings > Accessibility > Text and display > Display size), then slide the scale to the right, which will increase app icons, message buttons, and other interface settings.

If you don't need the text and the UI elements made larger by default, then you may be better served by a magnifying glass, which can highlight certain parts of the screen only when you need them. Fortunately, as accessibility options go, it's gotten better and easier to activate on both iOS and Android devices, and is particularly good for fine print and images that you can't natively zoom into. Here's what you need to know to do this:

• For iPhone: Go to Settings > Accessibility > Zoom and enable Zoom. You can then double-tap the screen with three fingers to toggle the magnification on and off. When enabled, you can drag the magnifying glass around with your finger for finer control.
• For Android: Head to Settings > Accessibility > Magnification and enable the Magnification shortcut. Tap the accessibility button (if you have one), or triple-tap the screen to magnify the display.

You should enable the system text scaling as well as the dedicated magnification shortcut for both iOS and Android to give yourself a handy way to make things bigger.

As well as these three proven and effective methods, there are a few other things you can do, too. For iPhones, you can also add a Text Size tool directly to the Control Centre as a quick shortcut, meaning you can quickly access it by swiping down from the top-right corner on a per-app basis. On Android, you can long-press on the home screen for the settings menu to adjust the grid size and change from the default of 5x5 to 4x4, which will automatically make the icons bigger. Alternatively, you can use a third-party launcher, such as Nova or Big, for custom icon sizing too, if you're comfortable with external apps.

Now that we understand how it works, there are a few things to consider when tweaking text and layout size on mobile. Chiefly, the app layout overflows, meaning that large text settings can sometimes awkwardly wrap around or be cut off from the display in some third-party apps that are not properly optimised with accessibility options. Contrast settings, particularly on some Android phones, can clash with bold text, which can make greys and blacks different from stock. You also need to consider how things will be adapted when web browsing through the likes of Safari, Chrome, or Edge, etc. Most web browsers have their own baseline zoom functions that can work independently of system-wide options, too.
