The words on the computer suddenly became bigger, how to adjust it smaller

There are a few ways to adjust the font size on the computer: 1. Choose the file that you want to reduce the font size, open the control panel, and select the font. In the font dialog box, you can choose the font size, color, layout, and other options to adjust the font size as needed. 2 Open any text editor or browser window and press the shortcut keys: Control + Shift + S(for Windows) or Cmd-Shift + S(for macs) to automatically adjust the font size. 3 In the browser, you can click the font button on the window title bar to select the desired font and adjust the size. In some document editing software, you can reduce the font size by adjusting paragraph indents and spacing. If the font suddenly becomes larger, it may be because the computer is processing a large amount of data or files, or some programs or windows are taking up a large amount of memory or CPU resources. In this case, you can try to reduce the number of programs or windows open, close unnecessary applications, or try to clean up the junk files on the computer to improve performance.
