Oh man, This is also bothering me. Please implement!

I'm preparing to write a thesis on a sensitive topic and I desperately want to do so in an encrypted online workspace. I've been happy with everything about Proton and I'm planning on paying for Premium - but not if I can't format my thesis!
I'm really shocked this isn't an option. PLEASE implement it asap. There's clearly a huge demand! Give me double spacing and take my money!

Agreed. I am editing my resume and need to change the spacing, and I cannot do so on this platform. I really want to make Proton my full-time space for managing my online life, but not being able to change line spacing is a basic need for editing something online.

I also really want to migrate but as a college student can't due to this - professors grade in part on papers following MLA and APA formats. This would be a dealbreaker for anyone taking a college class. The current automatic extra space after a paragraph is baked in if composed in Proton Docs, and cannot be removed by copying to a different word processor later. So until this is fixed, College students can't use Proton Docs.

This is a deal breaker. I really want to migrate everything over here, but this is a big issue.

The fact that this still isn't a baseline feature for Docs is concerning. I really want to migrate over from Google, but this is a dealbreaker for me.

I'm fairly certain line spacing was on the 2025 Spring Roadmap. What happened to that?

I migrated all my Google docs (hundreds) and only now realize there are no choices in Proton Docs for line spacing and formatting. Please update this!

Yes, please! Formatting of line height would be very welcome.

I'm a writer and small business owner, and I'd like to move hundreds of documents out of google drive and migrate over to Proton drive to protect my data. As many others have said here, the lack of clarity and control around spacing, margins, and formatting in Proton Docs raises significant barriers. I was set to begin migrating documents in September but seeing that this request has been in place for so long, I will have to keep researching better platforms.

I am migrating a long document from Google Docs, and the double-spacing minimum just won't work for readability. I can't see Proton Docs yet as viable. Alpha?

Not being able to control line spacing is preventing me from migrating from G-docs. Single spacing is used a lot in my notes. Thanks.

Yes! This please. An option for line and paragraph spacing in Proton Docs is crucial. And seeing the actual edges of a Proton Doc. As it currently stands, I have no idea how large the margins are or how many pages the Doc is. How is one supposed to compose a letter or resume this way? This is one of the many reasons I haven't been able to make the full jump from Google Drive yet.

Please add the ability to control line spacing within and between paragraphs. This is the main thing keeping me from migrating from Google Docs.

I can't use Proton Mail professionally, without coherent spacing between paragraphs. All forwarded emails from Outlook, for instance, make no sense with the lines and embedded images all over the place. Readers don't know what goes with which line or heading.

This is a critical feature for me as well. Without being able to set things such as line spacing in a document, it loses the professional formatting quality I need my docs to have.

Please add a way to specify wanted line spacing, e.g. 1, 1.15, 1.5 etc. Also, why is there a bigger gap between lines when hitting the Enter button?

would like to migrate from Google, but this is one required feature!

I use single line spacing in all my emails/documents & this is critical for me too.

Docs is great for quick notes but needs more parity to ms docs/only office.

We'll be patient as this is rolled out!

I agree with WH comment, I'd like to migrate off Google drive, but I need a few more edit features. Line spacing is an important one. Format painter would be another.

Yes, please. Single line spacing would be great.
