If you want a "reasonable amount of letters/words fits on each row", then make the column smaller. Don't compare this to print - no even semi-mainstream printed publication or book has type this large.

On desktop, the type on this site is unreasonably large. It is considerably larger than any other website that has long form content. It is extremely uncomfortable to read on my 13" MacBook Pro (which is a fairly common laptop/screen size).

Thankfully Safari gives me a 'Reader' version that's much easier to read. Compare the Reader version https://imgur.com/a/gs00JWD to the original version https://imgur.com/a/Waob1VZ
