I usually just use BDSup2Sub to shift PGS subtitles into bounds of the movie after black bars have been cropped in a recode.

I noticed the exported PGS always increase in file size, roughly around 10%, compared to the source PGS. Any reason for this?

I'm not talking about PGS with multiple PDS/ODS which may explain the increase. It happens even with simple PGS I created with SubtitleEdit.
