How to Zoom In and Out on a Mac: Every Method for 2026

To zoom on a Mac, press Command-Plus (+) or Command-Minus (-) in apps such as Safari, Chrome and Word, or pinch on a trackpad. To magnify the whole screen, turn on Zoom in System Settings > Accessibility > Zoom, then press Option-Command-Plus. Option-Command-8 switches between zoomed in and out.

Tiny text has a talent for showing up at the wrong moment: the small print in a contract PDF, one cell on a spreadsheet somebody is sharing. The confusing part is that a Mac has several separate zoom systems, so a shortcut that works on a webpage can do nothing on the desktop. This guide sorts them by what you're trying to enlarge, then covers meetings, permanent size changes, and how to get back to normal when the screen gets stuck. Menu names match Apple's guide for macOS 27.

How to zoom in and out with keyboard shortcuts on a Mac

Command-Plus zooms in and Command-Minus zooms out in many everyday Mac apps, but only inside that app. These shortcuts leave the menu bar, Dock and other windows alone. On a US keyboard the plus sign shares a key with the equal sign, which is why Microsoft writes Command-= where Apple and Google write Command-Plus. It's the same key.

In Mail, those keys change the size of the message you have open. If it's the inbox list that's too small, that's a different setting, covered in our guide to Mac Mail's fonts. Microsoft Outlook for Mac behaves similarly: Microsoft's page says Command-Plus enlarges an email open in its own window, and Control-Command-Z opens a Zoom dialog while you're writing, which resets once you send.

How to zoom in Preview

Preview has more zoom controls than most Mac apps, and they're the ones I reach for most with contracts. Apple's Preview guide lists View > Zoom In, View > Zoom Out, View > Actual Size and a Scale field where you type an exact percentage. When I need to read a signature block at the bottom of a scanned contract, I choose Tools > Rectangular Selection, drag around it, then choose View > Zoom to Selection. The percentages stop mattering, because the part I care about fills the window. Preview's shortcut list also gives Option-Command-0 for actual size and Option-Command-9 to fit all images.

How to zoom in Keynote and Pages

Keynote and Pages each have a Zoom pop-up menu in the toolbar. Keynote also offers View > Zoom > Zoom In, with a range from 10 to 400 percent. Pages offers Fit Width and Fit Page, and you can change where new documents open under Pages > Settings > General > Default Zoom.

How to zoom on a Mac with a trackpad

A Mac trackpad zooms with two gestures, a pinch and a two-finger double-tap. Spreading two fingers apart, which Apple's Safari guide calls pinching open, zooms in; pinching them together zooms out. Double-tapping with two fingers is Smart zoom, which zooms into a webpage or PDF and back out again.

Smart zoom works best on a column of text, since one double-tap does the job a pinch takes several tries to get right. Pinching gives finer control on photos and maps. If either gesture does nothing, open System Settings > Trackpad and check it under Scroll & Zoom.

How to zoom on a Mac with a mouse

A Magic Mouse zooms with Smart zoom: double-tap with one finger to zoom into a webpage or PDF and back out, and that's the only zoom gesture on Apple's Magic Mouse list. The switch is in System Settings > Mouse, a page that only shows up while a wireless mouse is connected.

For any other mouse, or for zooming the whole screen with a Magic Mouse, use the scroll-wheel method. Turn on Use scroll gesture with modifier keys to zoom in Accessibility > Zoom, pick Control, Option or Command, then hold that key and scroll. Teams has its own version of this: Microsoft lists Command plus the mouse wheel for its interface.

How to zoom the entire Mac screen

macOS Zoom magnifies the entire screen, so it reaches things the in-app shortcuts can't, such as an app with no zoom command of its own. It's an accessibility feature that's easy to overlook. Apple's Zoom guide gives three ways to control it, and you can turn on any combination:

1. Choose Apple menu > System Settings, click Accessibility in the sidebar, then click Zoom.
2. Turn on Use keyboard shortcuts to zoom to get Option-Command-Plus, Option-Command-Minus and Option-Command-8.
3. Turn on Use trackpad gesture to zoom to double-tap with three fingers and drag to zoom gradually. A three-finger double-tap alone switches zoom on and off.
4. Turn on Use scroll gesture with modifier keys to zoom, then choose a key in Modifier key for scroll gesture.

I keep the scroll method on and leave the three-finger gesture off. The first time I enabled the gesture, I double-tapped by accident during a meeting and thought the display had failed. Holding Control and scrolling is hard to do by mistake, and it stops the moment I let go of the wheel.

Choosing a Zoom style

The Zoom style setting decides what gets magnified:

• Full Screen enlarges the entire display. It suits working at a higher magnification for a while. With two displays, Zoom each display independently lets each one keep its own level.
• Split Screen keeps a magnified view along one edge of the screen, with the normal view beside it. It's useful for following along in one spot while the rest stays readable.
• Picture-in-Picture puts the magnified view in a box around the pointer, like a loupe. This is my pick for quick checks, because nothing else on screen moves.

Advanced settings hold a few options worth a look. Zoomed image moves sets how the view follows your pointer. Flash screen when notification banner appears outside zoom view catches alerts you'd otherwise miss. Restore zoom factor on startup reapplies your zoom level when you restart, so turn that off if you'd rather start at normal size every morning.

Enlarging just the text under your pointer

Hover Text shows a large copy of whatever text you point at, without moving anything else. The switch is in System Settings > Accessibility > Hover Text. Once it's on, point at some text and hold Command. Hover Typing, on the same page, shows a bigger copy of what you're typing, which helps when a form field uses tiny type.

How to zoom in or out during a video call on a Mac

In a meeting there are two separate questions: making someone else's shared screen bigger for you, and making your own screen bigger for them.

To enlarge what someone else is sharing: in the Zoom video app (a different thing from the macOS feature of the same name), click View Options, hover over Zoom Ratio and choose a ratio. In Microsoft Teams, Microsoft's help pages don't agree on the keys for shared content: one lists Option-Command-=, and another lists Option-Shift-Plus. Try both before an important call. If it's the words you're missing and not the slides, turning on live captions may help more.

To show others what you've enlarged: turn on Show zoomed image while screen sharing in the Advanced options for macOS Zoom. It requires macOS 15.1 or later. I learned to care about this setting while walking a client through a pricing sheet: I magnified one row, kept talking, and the client asked which row I meant. Run a test call with a colleague in the meeting app you actually use before you depend on it. For a plain document, zooming inside the app is the safer choice, since the shared window simply shows what's in it.

How to make everything bigger on a Mac permanently

Zooming is temporary. If you're zooming into the same things every day, change the size of the display itself and stop reaching for shortcuts. Apple's guide lists these options, and I'd try them in this order:

1. Text size: go to System Settings > Accessibility > Display, click Text size and drag the slider. It covers the desktop, sidebars and apps set to the preferred reading size, and you can set a size per app. Try this first, because it leaves your resolution alone.
2. Larger Text: go to System Settings > Displays and click Larger Text. This lowers the resolution so everything on screen appears larger, and it applies everywhere at once.
3. Default browser zoom: in Safari, go to Safari > Settings > Websites > Page Zoom and choose a percentage next to When visiting other websites. In Chrome, go to Settings > Appearance > Page zoom.
4. Icons: Control-click the desktop and choose Show View Options for desktop icons, or use the Size slider in System Settings > Desktop & Dock for the Dock.

There's a middle ground in the browser. A vendor portal I log into uses very small type, so I set a bigger zoom for that one site from the Page menu in Safari's Smart Search field and left everything else alone. Safari remembers that level when you come back, though not a level you reached by pinching.

How to fix a Mac screen stuck zoomed in

A Mac screen that's stuck zoomed in usually means macOS Zoom is on, and Option-Command-8 switches it back if keyboard shortcuts are enabled. The clue is that the picture slides around as you move the pointer. Work down this list until it clears:

1. Press Option-Command-8.
2. Hold Control and scroll down. If that does nothing, try Option or Command, since the scroll key can be changed.
3. On a trackpad, double-tap with three fingers.
4. Press Option-Command-F5 to open the Accessibility Shortcuts panel and turn off Zoom there. On a Mac with Touch ID, pressing Touch ID quickly three times opens it too. If Zoom isn't listed, add it in Accessibility > Shortcut.
5. Open System Settings > Accessibility > Zoom, turn on Use keyboard shortcuts to zoom, then press Option-Command-8. Once you're back to normal, turn off Restore zoom factor on startup under Advanced if the zoom returns after a restart.

Other kinds of "too big" have different causes:

Mac zoom versus resizing a window

Making a window bigger isn't the same as zooming, though it often solves the same problem. Hold the pointer over the green button in a window's corner and Apple's tiling menu offers Fill and Entire Screen, and the same options sit under Window > Move & Resize. Fn-Control-F makes the window fill the desktop, and Fn-Control-R puts it back. Text stays the same size, but you'll see more of the page before you need to zoom at all.

How to zoom in on things around you with a Mac

The Magnifier app uses a camera to enlarge what's physically in front of you, and it doesn't touch what's on your screen. Open Magnifier, click Camera in the menu bar to choose a camera, then use the Zoom In and Zoom Out buttons. It works with a Mac laptop's built-in camera, a USB camera or an iPhone. I've used my iPhone this way for the small print on a paper form, since holding the phone steady is easier than leaning over the desk.

How to add a zoom shortcut to an app that doesn't have one

If an app has a zoom command in its menus but no shortcut, you can add your own in System Settings > Keyboard > Keyboard Shortcuts > App Shortcuts. Apple's steps work like this, using Keynote's menu as the example:

1. Select App Shortcuts, then click the Add button.
2. In the Application pop-up menu, choose the app.
3. In Menu title, type the command exactly as it appears, with -> between menu levels: View->Zoom->Zoom In.
4. Click Keyboard shortcut, press the keys you want, and click Done.

Capitalization has to match, and a shortcut that conflicts with an existing one won't work until you change one of them. The same method works for email commands, as in custom Apple Mail keyboard shortcuts.

Which Mac zoom method to set up first

You don't need all of this. If you only set up a little, make it these:

• Learn Command-Plus and Command-Minus. They cover most reading in a browser and Word, with nothing to set up, and Command-0 resets Chrome and Word.
• Turn on the Control-scroll gesture in Accessibility > Zoom. It gets you to anything on screen, including apps that won't zoom on their own.
• Turn on the keyboard shortcuts too, so Option-Command-8 is there as your way out.
• Change Text size if you notice you're zooming into the same app every day.
