To use the magnifier on a Windows computer, press the Windows logo key + Plus sign (+) to turn it on, then use the same key with Minus (-) to zoom out and the Windows logo key + Esc to turn off magnifier. On a phone or tablet, the magnifier is accessed through the device's accessibility settings and uses the camera to zoom in on real-world objects like labels, menus, or fine print.
How to use the magnifier on Windows
Windows includes a built-in Magnifier tool that can enlarge any part of the screen. The fastest way to start it is with the keyboard shortcut: press the Windows logo key + Plus sign (+). To stop magnifying, press the Windows logo key + Esc. To zoom in or out once Magnifier is on, press the Windows logo key + Plus (+) to increase zoom or the Windows logo key + Minus (-) to decrease it.
Magnifier offers three views that you can cycle through by pressing Ctrl + Alt + M:
- Full Screen: The entire screen is magnified. Move your mouse to pan around.
- Lens: A movable rectangular lens follows your mouse pointer, magnifying only the area under it while the rest of the screen stays at normal size.
- Docked: A magnified strip appears at the top of the screen, while the main screen remains at normal size.
You can also enable Magnifier through Settings. Go to Start > Settings > Accessibility > Magnifier and turn on the Magnifier switch. From the same settings page, you can configure Magnifier to start automatically after or before Windows sign-in, so it is ready every time you log in.
How to use the magnifier on Mac
Mac computers have a dedicated Magnifier app that uses your iPhone or a connected USB camera to magnify your physical surroundings. Open the app and point the camera at the object you want to enlarge. You can adjust brightness and contrast to improve visibility, and apply color filters to make details stand out more clearly. The app lets you zoom in on anything around you, from a pill bottle label to a circuit board.
How to use the magnifier on iPhone and iPad
The Magnifier feature on iPhone and iPad turns the device's camera into a powerful magnifying glass. After enabling it in Settings > Accessibility > Magnifier, you can open it quickly. Once active, use the on-screen controls to adjust brightness, contrast, and color filters to suit the lighting and your vision. The flashlight can be turned on to illuminate dark areas, and focus lock keeps the image steady while you move the device. A Capture button freezes the current view, letting you inspect details and make adjustments without holding the camera still. On iOS 27 or later with Apple Intelligence (available on iPhone 15 Pro, iPhone 15 Pro Max, or iPhone 16 models or later), Magnifier can provide scene descriptions and answer questions about surroundings.
How to use the magnifier on Android
Android devices include a Magnification feature under Settings > Accessibility > Magnification. Turn on the "Magnification shortcut" and choose how you want to activate it: using the Accessibility button, holding the volume keys, or triple-tapping the screen. Once activated, triple-tap the screen to zoom in, then drag two fingers to scroll around the magnified area. Pinch with two fingers to adjust the zoom level. Android Magnification supports both full-screen magnification, which enlarges the entire display, and partial-screen magnification, which shows only a magnified window. On Android 14 and up, a Magnifier settings panel allows customizing magnifier size and zoom.
Tips for using any magnifier effectively
Getting the most out of a magnifier takes a little practice. Position the device at a comfortable distance from the object you want to see, and move it slowly closer or farther until the image is sharp. Find the right zoom level for the task: too much zoom can make it hard to keep the object in view, while too little may not show enough detail. Steady the device by resting your elbow on a table or bracing your hand against a solid surface, which reduces shaking. Practice using the tool in different situations, such as reading a menu in low light or examining a small part, so that activating and adjusting it becomes second nature.
