Windows 11’s scroll bars are slim by design, and in many apps they shrink to a thin line until you hover over them. That looks clean, but it can make scroll bars hard to see and grab, especially on high-resolution screens, with a touchpad, or if you have limited vision or dexterity. You can make them easier to use in two ways: keep them always visible with a simple setting, and make them wider with a registry change.
Method 1: Always Show Full-Size Scroll Bars
This is the quickest fix and is often all you need.
- Press Windows + I to open Settings.
- Go to Accessibility > Visual effects.
- Turn on Always show scrollbars.
Now scroll bars in the Settings app, Start menu, File Explorer, and many modern apps stay at their full width instead of collapsing to a thin line. You can also find this option by typing “scroll bars” in the Settings search box.
Method 2: Make Scroll Bars Wider with the Registry
To change the actual width of scroll bars in classic desktop apps, edit two values in the registry. Windows 11 doesn’t have a Settings option for this.
Important: Editing the registry incorrectly can cause problems. Back up the key first with File > Export in Registry Editor.
Step 1: Open Registry Editor
Press Windows + R, type regedit, and press Enter. Click Yes at the prompt. See how to open Registry Editor in Windows 11.
Step 2: Go to the WindowMetrics key
Paste this into the address bar and press Enter:HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics
Step 3: Change ScrollWidth
Double-click ScrollWidth. The default value is -255. The value uses the formula -15 × the width you want in pixels, so -255 equals 17 pixels. For example:
- -300 = 20 pixels
- -375 = 25 pixels
- -450 = 30 pixels
Enter the new value and click OK. The Windows 11 Forum’s guide suggests staying between -120 (thinner) and -1500 (thicker).
Step 4: Change ScrollHeight
Double-click ScrollHeight and use the same value so horizontal scroll bars match. This also controls the size of the arrow buttons at each end.
Step 5: Apply the change
Sign out and back in, or restart your computer. Restarting Windows Explorer from Task Manager may also work.
Where the Registry Change Works (and Where It Doesn’t)
The WindowMetrics change affects classic Win32 apps, such as Control Panel, Notepad, and many older desktop programs. It doesn’t change scroll bars in Microsoft Store apps or modern interface areas like Settings and the Start menu, and some third-party apps draw their own scroll bars. Web browsers like Chrome and Edge also use their own scroll bar styles. For those, Method 1 and the options below help more.
Other Ways to Make Scrolling Easier
- Increase text size: In Settings > Accessibility > Text size, a larger setting enlarges many interface elements.
- Change display scaling: In Settings > System > Display > Scale, choose a higher percentage to make everything, including scroll bars, bigger.
- Adjust mouse wheel speed: In Settings > Bluetooth & devices > Mouse, change how many lines scroll at a time so you rely less on the scroll bar.
- Scroll inactive windows: In the same Mouse settings, turn on scrolling inactive windows when hovering over them.
Why You Might Want Wider Scroll Bars
Wider scroll bars are an accessibility improvement for many people. They’re easier to click with a mouse, easier to hit with a finger on touchscreens, and easier to see at a glance. If you use a high-resolution laptop screen at a low scaling setting, the default 17-pixel scroll bar can feel tiny. People with tremors, limited mobility, or low vision often benefit the most, and larger pointers pair well with this change.

How to Undo the Change
Set both ScrollWidth and ScrollHeight back to -255, then sign out and back in. To let scroll bars auto-hide again, turn off Always show scrollbars.
Frequently Asked Questions
Why are my scroll bars so thin in Windows 11?
Windows 11 uses overlay scroll bars that shrink when you’re not using them. Turn on Always show scrollbars to keep them full size.
Can I change scroll bar color?
Not with a built-in setting. Dark and light mode and high-contrast themes change their appearance.
Summary
To widen scroll bars in Windows 11, turn on Settings > Accessibility > Visual effects > Always show scrollbars. For wider scroll bars in classic apps, set ScrollWidth and ScrollHeight in HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics to a larger negative number, such as -375, and sign out to apply.
