Change Title Bar Text Size in Windows 10 Creators Update

Windows 10 Title Bar Titlebar Window Frame Icon

Starting with Windows 10 Creators Update, Microsoft has removed the ability to change advanced text sizing options. Various options to configure the text size for user interface items like menus, title bars, icons and other elements have been removed along with the classic Display settings. Here is how you can change the Title Bar text size in Windows 10 Creators Update.
Windows 10 Custom Title Bar FontLike other text sizing options, the text size of title bars could be configured in "Advanced sizing of text" classic applet. Here is a screenshot from Windows 10 Anniversary Update version 1607:

After you click that link, the following window will appear on the screen:

In Windows 10 Creators Update version 1703, this dialog has been removed. Thankfully, it is still possible to change the text size using a Registry tweak. Let's see how.

To change title bar text size in Windows 10 Creators Update, do the following.

To adjust the text size of title bars in Windows 10 version 1703, apply a Registry tweak as described below.

  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. Change the string value named "CaptionHeight".

    Set its value data 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
  4. Repeat the same for the parameter CaptionWidth.

The steps above will change the size of the title bar. Now, let's tweak the font appearance.

The menu font size is encoded in the value CaptionFont, which is a value of REG_BINARY type. It stores a special structure "LOGFONT".

You cannot edit it directly, because its values are encoded. But here is the good news - you can use my Winaero Tweaker, which will allow you to change the menu font easily.

  1. Download Winaero Tweaker.
  2. Install the app and go to Advanced Appearance\Window Title Bars.
  3. Change the title bar font and its size to anything you want.

Now, sign out and sign in again to your user account to apply the changes. If you are using Winaero Tweaker, you will be prompted to sign out.

That's it!
