    How to Change Size of Caption Buttons in Windows 10


    In Windows 10, it is possible for you to change the size of caption buttons (minimize, maximize, close) to be smaller or larger.

    Using larger caption buttons will also increase the height of title bars.

    This tutorial will show you how to change the size of caption buttons and height of title bars for your account in Windows 10 and Windows 11.

    This will not affect the caption buttons for Store apps and any modern UI (ex: Settings).



    EXAMPLE: Default and larger size of caption buttons

    Here's How:

    1 Open Registry Editor (regedit.exe).

    2 Navigate to the key below in the left pane of Registry Editor. (see screenshot below)

    HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics

    3 In the right pane of the WindowsMetrics key, double click/tap on the CaptionHeight string value to modify it. (see screenshot above)

    4 Enter a value between -120 (smaller) to -1500 (larger) for what you want, and click/tap on OK. (see screenshot below)

    -330 is the default value.

    The value uses the following formula: -15 x size you want in pixels.

    For example: -15 x 22 = -330

    5 When finished, close Registry Editor.

    6 Sign out and sign in to apply.


    That's it,

    I used the method described in this tutorial to change Caption Height, but, in my version of Windows 10 (10.0.18363 Build 18363) the system resets the registry entry to the default value of -330.

    I have not yet figured out exactly what causes the reset, but I have edited the CaptionHeight value several times, and each time, after a couple of days or so, I notice that the height of the title bar is back to the default height. Then I look at the registry and I find that the value of CaptionHeight is back to -330.

    Any ideas on how to make the change be permanent?

    Hello @gvannucci,

    Do you have 3rd party software installed that could be resetting this back to default?

    I don't think so. I have Taskbar Tweaker, which customizes the taskbar but, supposedly, does not change windows metrics.

    Other than that, I have work-related software like MS Office, which should not mess with the appearance of windows.

    I suppose for now, try to remember if anything may have been updated, installed, changed, etc... right before it changes next to help narrow down a cause.

    Just a note about what the new Windows 11 has for the Maximize/Restore button.
