And also, it doesn't matter if it only has 4 votes. Everybody would still benefit from it. Probably not a lot of people uses the align feature OR they have huge screens, which not everybody can afford, be it for financial reasons or for space reasons, especially freelance translators. It would be a real changer for the comfort of work.

It shouldn't matter what font size the original document has. Adapting the font means taking into account that not everybody has a sight of 10/10, and also sight may change over the years. If adapting fonts is possible for the Editor, then it should also be possible for the other features of the software. And yes it's a duplicate, because it doesn't seem to matter to Studio.

Studio takes what's in the document so it should display in a similar way as in the originating application. Also could you provide a link to a forum thread where this is talked about for reference and convenience here? Also this is a duplicate of https://community.sdl.com/ideas/translation-productivity-ideas/i/trados-studio-ideas/font-size-options-in-align so I'll close this here as a duplicate but feel free to vote for the duplicate idea (which has three votes only at this stage).
