How to Adjust Subtitle Font Size

Soft subtitles cannot be resized, as they are controlled by the player. Hard subtitles can be adjusted by changing the Hard subtitle font pixels value in Menu -- Tools/Options - Advanced options. The default setting is 14.

Control the Number of Characters per Line in Subtitles

By default, Chinese, Japanese, and Korean subtitles display 30 characters per line, while other languages display 60 characters per line. You can adjust these values by modifying the Characters per line for Chinese/Japanese/Korean subtitles and Characters per line for other subtitles settings in Menu -- Tools/Options - Advanced options.
