How to Change Mouse Cursor Size in Windows 10 and 11

Introduction / Why This Is Needed

The default mouse cursor size in Windows can be too small on modern high-resolution monitors or for users with impaired vision. Changing the pointer size is a simple but important accessibility setting that significantly improves computer comfort. In this guide, you will learn two ways to increase or decrease the cursor: through the system's graphical interface and by editing the registry for more flexible control.

Requirements / Preparation

• Operating system Windows 10 or Windows 11.
• A user account with administrator privileges (especially for the registry method).
• A system restart may be required to apply changes made via the Control Panel.

Step-by-Step Instructions

Method 1: Standard Windows Settings (Recommended)

This method uses the system's built-in cursor schemes and does not require registry editing.

Step 1: Open the Mouse Properties window

1. Press the Win + I key combination to open Windows Settings.
2. Navigate to «Devices» → «Mouse».
3. Scroll down on the right side of the window and click «Additional mouse settings». The classic «Mouse Properties» window will open.
   • Alternative path: Open the Control Panel (via the Start menu search), select «Hardware and Sound» → «Mouse».

Step 2: Select a suitable cursor scheme

1. In the «Mouse Properties» window, go to the «Pointers» tab.
2. In the «Scheme» section, expand the dropdown list. You will see several built-in options:
   • Normal (system) — the standard size.
   • Large (extra large) — the cursor is enlarged by approximately 1.5 times.
   • Extra large (extra large) — the maximum predefined size.
3. Select a suitable scheme (for example, «Large (extra large)»). You will see the change immediately in the preview area.
4. Click «Apply», and then «OK».
5. Changes will take effect for most applications after restarting your computer. For some programs (like Windows Explorer), logging out and back in may be sufficient.

Method 2: Registry Editing (For Precise Control)

This method allows you to set an arbitrary size but requires more caution.

Step 1: Launch the Registry Editor

1. Press Win + R, type regedit, and press Enter.
2. If a User Account Control (UAC) prompt appears, click «Yes».

Step 2: Find and modify the CursorSize parameter

1. In the Registry Editor, navigate to the path:

   HKEY_CURRENT_USER\Control Panel\Cursors
   

2. On the right side of the window, find the parameter named CursorSize (type: REG_SZ).
3. Double-click it to change the value.
4. In the «Value data» field, enter one of the following numbers:
   • 32 — standard size (100%).
   • 48 — larger (150%).
   • 64 — largest (200%).
   • Any other value from 1 to 99 — may result in a non-standard, but sometimes useful, size (e.g., 16 will shrink the cursor).
5. Click «OK».

Step 3: Apply the changes

1. Close the Registry Editor.
2. Restart your computer. The changes will only be applied after a full system reboot.

Verifying the Result

After restarting, verify that the cursor has changed size:

• Hover the mouse pointer over the desktop, in File Explorer, or in any browser window.
• Ensure the new size is comfortable to view.
• If the size did not change, check if you selected the correct scheme in the first method or entered the correct value in the registry.

Potential Issues

• Changes did not take effect after restarting.
  • Solution: Ensure you edited the CursorSize parameter in the HKEY_CURRENT_USER hive, not HKEY_LOCAL_MACHINE. For a system-wide change (all users), you would need to edit the parameter in HKEY_USERS\.DEFAULT\Control Panel\Cursors, but this is not recommended.
• After changing via the registry, the cursor became too large/small or unreadable.
  • Solution: Reset the CursorSize value to 32 (standard) or select an appropriate predefined scheme via the Control Panel (Method 1).
• Changing the size did not affect the cursor in a specific game or program.
  • Solution: Many applications, especially games, use their own pointer rendering (raw mouse input). You will need to look for cursor settings within the program itself (e.g., in Settings → Game → Interface). System settings do not apply to them.
• No access to edit the registry.
  • Solution: Ensure you are logged in with an administrator user account. If the computer is part of a domain, security policies may block access to regedit.
