How To Adjust Font Size on a Mac | Change More Than App Text

Mac font size can be increased from Accessibility > Display > Text size, while Finder, the menu bar, and some apps use separate controls.

Tiny menus or cramped app text can make a sharp display harder to read. The control for how to adjust font size on a Mac depends on what looks too small: supported app text, Finder labels, the menu bar, or the whole interface.

Start with the preferred reading-size setting because it changes text across several supported parts of macOS at once. If one area still looks too small, use the matching control below rather than making the entire interface larger.

Adjust Font Size Across Mac Apps And The Desktop

macOS Tahoe 26 lets you set a preferred reading size for the desktop, app sidebars, and compatible apps from Accessibility settings. Apps that do not follow the preferred reading size need their own text control.

1. Open the Apple menu in the top-left corner and choose System Settings.
2. Click Accessibility in the sidebar.
3. Click Display, scroll to the Text section, then click Text size.
4. Drag the slider to the right to make supported text larger, or left to make it smaller.
5. If a listed app needs a different size, open the pop-up menu beside that app and choose the size you want.

The desktop text, supported app sidebars, and listed apps set to Use Preferred Reading Size change as you adjust the control. If a listed app already has its own in-app text size, changing its size from System Settings replaces that app-level setting.

What If Only Finder Or Desktop Labels Are Too Small?

Finder and desktop labels can be resized without changing text throughout macOS. Both controls sit in Show View Options, but you open that panel from different places.

For a Finder window, open Finder and choose View > Show View Options, then use the Text size pop-up menu. The file labels in that Finder view resize immediately. Finder also lets you change icon size in Icon and List views, while Gallery view does not offer a text-size control and Column view does not offer an icon-size control.

For desktop labels, Control-click an empty area of the desktop, choose Show View Options, then choose a larger Text size. The filename labels on the desktop change as soon as you select the new size.

Where The Main Text Controls Live

Mac text sizing is split by screen area, so the setting that works depends on what looks too small. This table puts the current macOS controls in one place.

Change Text Size Inside Individual Apps

Individual app controls are useful when the system reading size feels fine but one app is difficult to read. Apple documents the current shortcuts and app-specific controls on its Increase font size and icons page.

In Calendar, Mail, Messages, and News, open the content you want to read and press Command-Plus Sign (+) to enlarge it or Command-Minus Sign (-) to reduce it. The visible content changes immediately, so you can stop when the size feels comfortable.

Safari separates text sizing from full-page zoom. Use Command-Plus Sign (+) and Command-Minus Sign (-) for text only; use Option-Command-Plus Sign (+) and Option-Command-Minus Sign (-) when you want text, images, and other page elements to scale together. You will see either the text or the whole webpage grow, depending on the shortcut.

Set Menu Bar And Sidebar Text Separately

The menu bar and app sidebars do not rely on the same control. macOS gives the menu bar a Default or Large size, while sidebar text changes together with sidebar icon size.

For the menu bar, open System Settings > Accessibility > Display, then set Menu bar size to Large. Apple requires you to sign out and sign back in for this setting; the menu-bar text appears larger after the new login session.

For sidebars, open System Settings > Appearance, then change Sidebar icon size. Choosing a larger icon size also increases sidebar text in Finder and supported apps such as Mail, News, and Photos.

Match The Control To What Looks Too Small

The most useful setting is the narrowest one that fixes the problem without making unrelated parts of the screen oversized. Use this table when several controls seem like they could solve the same issue.

Do You Need Bigger Text Or A Bigger Interface?

Use text-size controls when words are the problem; use display scaling when buttons, icons, windows, and text all feel undersized. Display scaling changes much more than font size.

Open System Settings > Displays and choose Larger Text if the whole interface needs to grow. Windows, icons, and text appear larger together. If you only need temporary magnification, System Settings > Accessibility > Zoom can enlarge the whole screen or a selected area without permanently changing app text sizes.

Keep Text Readable Without Enlarging Everything

A balanced Mac setup combines one broad reading-size setting with local adjustments only where they are needed. That keeps text readable without making every window, icon, and webpage larger than you want.

1. Set Accessibility > Display > Text size to a reading size that works across the desktop and supported apps.
2. Adjust Finder or desktop Text size only if file labels still look small.
3. Set Menu bar size to Large only if the menu bar remains hard to read, then sign out and back in.
4. Use app shortcuts for Mail, Messages, Calendar, News, or Safari when just one app needs larger content.
5. Choose Displays > Larger Text only when the entire interface, not just words, needs more visual size.

After those changes, the Mac should show larger text where you need it while leaving unaffected areas at their normal scale.
