How to Change the Magnifier Zoom Level in Windows 11

What is Magnifier?

Windows Magnifier is a screen-enlarging tool. It remembers the last zoom level you used and starts at that setting the next time you turn it on, so you only need to set your preferred level once. Microsoft provides further details on using Magnifier to improve screen visibility.

Microsoft has also updated the tool. Its “Windows news you can use: July 2026” post says Magnifier now has more precise zoom controls. That change comes through a Windows update and is rolling out gradually, so some PCs will get it later than others.

Why Use Magnifier?

Magnifier makes text and images clearer to see. That helps if you have low vision, if you work on a high-resolution display where everything looks small, or if you need a closer look at one part of the screen.

Because the zoom level is adjustable, you can use a gentle 150% for everyday reading or go much higher for fine detail. Pick the lowest level that still lets you read comfortably, since a very high zoom shows only a small part of the screen at a time.

Option 1Change Zoom Level Using Keyboard Shortcuts

1. Turn on Magnifier by pressing the Windows key + Plus (+) on your keyboard. The screen zooms in right away, and a small Magnifier toolbar appears.
2. To zoom in (make things bigger), press Windows key + Plus (+) again. Each press raises the zoom by one step, up to a maximum of 1600%. The content on your screen grows with every press.
3. To zoom out (make things smaller), press Windows key + Minus (-). Each press lowers the zoom by one step, down to 100%. To turn Magnifier off completely, press Win+Esc.

That’s it. You now have a fast way to raise and lower the zoom without leaving the keyboard, and Magnifier keeps the level you stopped at for next time.

Option 2Change Zoom Level Using Mouse Scroll Wheel

1. Turn on Magnifier (Windows key + Plus (+)). The mouse wheel method only works while Magnifier is running, so check that the toolbar or the magnifying glass icon is on screen.
2. Hold down the Ctrl and Alt keys on your keyboard. Keep them held for the next step.
3. While holding these keys, scroll your mouse wheel up to zoom in or scroll down to zoom out. The screen changes as you scroll, so you can stop exactly where the text looks right. Release Ctrl and Alt when you’re done.

That’s it. You now have a smooth way to fine-tune the zoom with your mouse, and the level you stopped at stays in place until you change it.

Option 3Change Zoom Level Using the Magnifier Toolbar

1. Turn on Magnifier (Windows key + Plus (+)). The Magnifier toolbar appears on your screen.
2. Look for the Magnifier toolbar that appears on your screen. If you only see a small magnifying glass icon, the toolbar is minimized. Click the icon to expand it again.
3. Click the + button to zoom in or the – button to zoom out. Each click changes the zoom by one step, and the screen updates straight away.

That’s it. You now have point-and-click control over the zoom level, which suits you if you prefer the mouse to keyboard shortcuts.

Option 4Change Zoom Level in Windows Settings

1. Press Win+I to open Settings⚙️. The Settings window opens with a list of categories on the left.
2. Click Accessibility on the left menu. The accessibility options appear on the right.
3. Click Magnifier on the right. The Magnifier page opens with its on/off switch and zoom options.
4. Under Zoom level, click the – or + buttons to change the zoom. If you don’t see the zoom controls, turn on the Magnifier switch at the top of the page first. On PCs that have received Microsoft’s more precise zoom controls, the controls may look different from this description.
5. Click here to open Magnifier settings directly
6. You can close Settings when you’re done. The new zoom level is saved and Magnifier will use it the next time it starts.

That’s it. You now have your zoom level set from the Settings app. To undo the change, return to the same page and click the – or + buttons until you reach your old level.

Option 5Change Zoom Level Using Registry Editor (Advanced)

You can change the Windows 11 Magnifier zoom level in Registry Editor by opening the tool with the Win+R shortcut, typing ‘regedit’, and editing the default magnification value. This advanced method lets you set an exact zoom percentage that the normal settings menu may not offer. You need administrator privileges to make these changes to your system settings.

⚠️ Admin privileges required

1. Press Win+R, type regedit, and press Enter to open Registry Editor. If a User Account Control prompt appears, click Yes. If you aren’t signed in as an administrator, you will be asked for admin credentials.
2. Navigate to this folder: Computer\HKEY_CURRENT_USER\Software\Microsoft\ScreenMagnifier. You can expand the folders in the left pane one by one until you reach it. The values stored in that folder then appear in the right pane.
3. In the right pane, double-click Magnification. An edit window opens for that value.
4. Select Decimal for the number format. This makes sure the number you type is read as a normal percentage rather than a hexadecimal value.
5. Type a number between 100 (100%) and 1600 (1600%) in the Value data box to set your zoom level. For example, 200 gives you 200%.
6. Click OK and close Registry Editor. If the new level doesn’t show up, turn Magnifier off (Win+Esc) and on again. If it still hasn’t changed, sign out of Windows and back in. To undo the change, repeat these steps and enter your old value, or import the backup you exported.

That’s it. You now have an exact zoom level stored in the Registry, and Magnifier will use it the next time it starts.

Summary

You can adjust the Windows 11 Magnifier zoom level with keyboard shortcuts, the mouse scroll wheel, the toolbar buttons or the Accessibility settings. The fastest way to change your zoom is to press the Win and the Plus or Minus keys together. You can also hold down the Ctrl and Alt keys while scrolling your mouse wheel to zoom in and out smoothly.

Microsoft’s July 2026 “Windows news you can use” post adds that Magnifier now has more precise zoom controls. The rollout is gradual, so some PCs will get them later. Here is a quick summary of each method.

• Keyboard shortcutsUse Windows key + Plus or Minus to zoom in and out. Press Win+Esc to turn Magnifier off.
• Mouse scrollHold Ctrl + Alt and scroll your mouse wheel. Magnifier must already be running.
• Magnifier toolbarClick the + or – buttons on the toolbar. If only a magnifying glass icon shows, click it to bring the toolbar back.
• SettingsGo to Settings › Accessibility › Magnifier and find the zoom level controls.
• Registry EditorChange the zoom level directly in the Registry (advanced users only, admin rights required).

Try whichever method works best for you. Each one gives you control over how much your screen magnifies. For everyday use, the keyboard shortcuts are usually quickest.

Because Magnifier remembers your last zoom level, you only need to set it once. If you want to go back, use any of the methods above and choose a lower level.
