Many users are not happy with the default appearance of window title bars in Windows 10. It is too tall and the window caption buttons (minimize, maximize, close) are quite large. If you want to reduce the title bar height and make window buttons smaller in Windows 10, here is how you can do it.
There are two ways to do it. To reduce the title bar height and make window buttons smaller in Windows 10, do the following:
Option one. Adjust window title bars appearance using Winaero Tweaker
In version 0.3.1, I added the appropriate option to Winaero Tweaker. Run it and go to Advanced appearance - Window Title Bars.
If you cannot reduce the title bar to the desired size like 15 or 16 px, you need to reduce the title bar font. Change it from Segoe UI, 9px to Segoe UI, 8px. This will resolve the issue.
Also, if you prefer huge title bars, it is a good idea to increase the title bar font.
All the changes you make in Winaero Tweaker will be applied instantly. No reboot is required.
Option two. Adjust window title bars appearance with a Registry tweak
It is possible to adjust window title bar height using Windows Registry Editor. This method is less effective than Winaero Tweaker and will not allow you to adjust fonts, but it is worth mentioning it for those who like tinkering with the system themselves.
- Open Registry Editor. If you are not familiar with Registry Editor, see this detailed tutorial.
- Go to the following Registry key:
Tip: You can access any desired Registry key with one click.
- Change the string value named "CaptionHeight". Set its value using the following formula:
-15*desired height in pixels
For example, to set the title bar height to 18px, set the CaptionHeight value to
-15*18 = -270
- 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. Also, you cannot tweak or change the title bar font, e.g. to reduce it and bypass the title bar height limit caused by the font size. The title bar font is stored as a byte array in the Registry. So, I recommend you to use Winaero Tweaker.
This trick also works in Windows 8 and Windows 8.1.
