My preference. Fonts are enlarged using the same or very similar styles. Arial (NPC names, subtitles, choices, etc), is on the small side but large enough.

An alternative that maximizes text size at the cost of compromising the game's original font scheme. Two similar, stylized fonts are used everywhere.

Another alternative for purists. No text styles are changed. They're only boosted to their largest available size. You may find some fonts uncomfortably small in 4k. In my opinion, the stylistic differences with mod 1 are minor.

An addon with a larger Arial font lacking apostrophes, most non-English characters, and a black border. Enlarges NPC names, subtitles, choices, and similar elements to a comparable size as mod 2. REQUIRES mod 1 or 3.
