How to say "fairly" in Japanese

• かなりJLPT N3approx.Common
  adverb, no-adjective, na-adjectiveThe straightforward choice when 'fairly' means 'quite' or 'considerably', as in a fairly long meeting or a fairly cold room. It states the level plainly, without the comparative flavour of 割と and 割に.
  ４マイルはかなりの距離きょりだ。↗

  Four miles is a good distance.
• 割とわりとJLPT N2approx.Common
  adverbCovers 'fairly' as 'comparatively' or 'relatively': the degree is judged against an expectation or baseline, as when something turns out fairly easy compared with what you expected. Close in meaning to 割に.
• そこそこCommon
  adverb, no-adjectiveA colloquial mimetic word for 'fairly' meaning 'reasonably, passably': the quality clears the bar but nothing more, so it often sounds lukewarm — work or cooking that is all right rather than good.
  まだ、完了かんりょうと言いうところまで行いっていないが、そこそこ成果せいかが出で始はじめてきた。↗

  It's not yet what you'd call finished but we're starting to get pretty good results.
• なかなかJLPT N4approx.Common
  adverb, na-adjectiveIt maps to 'very' and 'considerably' rather than a mild 'fairly', and it often implies the degree exceeds expectations, usually with an approving tone. Save it for 'fairly' that amounts to 'quite'.
  あいつは、なかなかいい奴やつだぜ！↗

  He is a good joker.
• 割にわりにCommon
  adverbThe same comparative adverb as 割と, largely interchangeable with it: 'fairly' as 'comparatively, relatively'. It often adds a 'considering the circumstances' nuance, implying the degree is more than the situation would suggest.

Choose 「かなり」 for a plain 'quite, considerably'; 「割と」 or 「割に」 when 'fairly' means 'relatively, against an expectation'; 「そこそこ」 for a lukewarm 'reasonably, passably'; 「なかなか」 only where 'fairly' amounts to 'quite' with an approving tone.
