Change Mouse Scroll-Wheel Speed on Windows & macOS

The scroll wheel controls how far a page moves with each notch. This guide shows how to slow or speed up scrolling in Windows 10/11 and modern macOS.

What you're changing: The OS decides how many lines or an entire screen move for each wheel tick.

Windows & macOS

Windows

Open Settings → Bluetooth & devices → Mouse.
Under Scrolling, adjust Lines to scroll at a time or pick One screen at a time.
Classic route: Control Panel → Mouse → Wheel lets you set vertical and horizontal amounts.
Advanced: edit WheelScrollLines in HKEY_CURRENT_USER\\Control Panel\\Desktop.

macOS

Open System Settings → Mouse.
Drag the Scrolling speed slider to taste.
Magic Mouse or trackpad options may appear under Accessibility → Pointer Control → Mouse & Trackpad.

Tips & Troubleshooting

Vendor utilities for gaming mice can override OS scrolling.
Clean the wheel and update drivers if behaviour is erratic.
Scroll preferences apply per user account.
