How to change the size of scrollbars in Windows 10

Since Windows 8, Microsoft removed all options to control any advanced appearance settings of the operating system. While you can still change the Windows theme, you cannot adjust how specific controls look, like it was possible in all releases starting from Windows 95 all the way up to Windows 7. Windows 10 does not bring those options back. If you are looking for a way to change the appearance of scrollbars in Windows 10, in this article I will share how it can be done.


There are two ways to change the size of scrollbars in Windows 10. Let's explore them.

Change scrollbar size with Winaero Tweaker

In version 0.3.1, I added the appropriate option to Winaero Tweaker. Run it and go to Advanced appearance - Scrollbars. Here, you can adjust the width of scrollbars and change the size of scrollbar buttons in Windows 7, Windows 8/8.1 and Windows 10. The changes will be applied instantly. No reboot is required.

The alternative way involves Registry editing.

Adjust scrollbars appearance with a Registry tweak

It is possible to adjust window title bar height using Windows Registry Editor. This method is worth mentioning for those who like tinkering with the system themselves.

  1. Open Registry Editor. If you are not familiar with Registry Editor, see this detailed tutorial.
  2. Go to the following Registry key:
    HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics

    Tip: You can access any desired Registry key with one click.

  3. To change the scollbar width, change the string value named "ScrollWidth". Set its value using the following formula:
    -15*desired width in pixels

    For example, to set the scrollbar width to 18px, set the ScrollWidth value to

    -15*18 = -270
  4. To change the size of scrollbar buttons, edit the value ScrollHeight using the same formula. Windows 10 chage scrollbars size
  5. After that, sign out and sign in back to your user account to apply the changes.

That's it. Note that if you edit the Registry manually, the changes are not instant. So, if you wish to experiment to determine the right size of the scrollbar, I recommend you to use Winaero Tweaker.

This trick also works in Windows 8 and Windows 8.1.

    Hi

    thanks for this

    being able to change the scroll bar width is very handy

    also could be essential for disable people who find it hard to see

    which is probably why it was there in the old versions !!!

      Gary,
      Amen!
      I have very very poor eyesight and that is one of the reasons that I can’t give
      up XP on my; main computer. Are there any more aids that can be added to
      Windows 10? Like the large calculator that was on Windows 7 or 8?
      I’ve been trying for over a year to customize my Windows 10 machine before
      I switch to it as my main.
      Thanks,
      Ron

    Regarding the Vertical Scroll Bar Width, is there any easy way to adjust the width if the bar(s) on Windows 10 Start All Apps Drowdown List? It’s so narrow that my start icons are flying around!

      Unfortunately, it is an Universal app. I cannot change anything in the Start menu.

    I used tweaker to change the width and height of my visually impaired wife’s scroll bar. It worked for IE and Firefox browsers but did not change the scroll bar on the Microsoft Edge window. Any suggestions?

      Edge is a modern app.
      It does not follow win32 metrics.
      You need to change its SOURCE CODE :)
      So, not possible.

    I tried both methods for changing scroll bar dimensions in windows 10. Each of them modified the values in the register but without changes on the screen. What now ?

      I can say that Edge uses Universal Apps platform which does not respect system metrics.
      Chrome uses its own interface framework. I know nothing about metrics support implemented there. If it fails, then it does not read the mentioned Registry value.

      For Google Chrome and the new Opera, I can recommend you the Rescroller extension: https://chrome.google.com/webstore/detail/rescroller/ddehdnnhjimbggeeenghijehnpakijod Don’t use GarbEdge, it is crap.

      Firstly you could stop typing in CAPS. It is a bit rude. Also if changing scrollbar via Winaero Tweaker doesn’t change your scrollbar in other apps, there is no other way to change it.

    Changing Scroll Bar Size doesn’t seem to do anything. What’s it supposed to do?
