How to say "extent" in Japanese

Choosing the right word
  • ほどJLPT N4approx.Common
    noun, adverbThe word for extent as degree: how much, how far, to what extent. Use it for the degree or measure of something rather than its physical range or bounds.
  • 範囲はんいJLPT N3approx.Common
    nounExtent as the area, range, or bounds something covers: the extent of the damage, the scope of someone's authority. Choose it when 'extent' means how widely something spreads or applies.
    自分じぶんの収入しゅうにゅうの範囲はんいで生活せいかつするようにしなさい。↗
    Try to live within your income.
  • 加減かげんJLPT N3approx.Common
    noun, noun (suffix)Really means degree or amount in the sense of adjustment or balance, getting something to the right level. Seldom the word you want for 'extent'; keep it for cases where balance is at issue.
    お肉にくの焼やき加減かげんは、いかがなさいますか?↗
    How would you like your steak cooked?
  • 寸法すんぽうJLPT N2approx.Common
    nounIts 'extent' sense is concrete: the measurements, size, or dimensions of a physical thing. For abstract extent — degree or scope — it is not the word you want; think 'measurement' or 'size'.
    あなたの寸法すんぽうを計はかるのを許ゆるして下ください。↗
    Please allow me to measure you.
  • nounA katakana loanword whose home sense is 'scope': the range a project, study, or piece of work covers. Use it when 'extent' really means scope or range, not degree or amount.

Choose 「ほど」 for extent as degree, 範囲 for the area or scope something covers, 「スコープ」 for the scope of a project or study; 加減 and 寸法 are marginal choices, really degree of adjustment and physical size.
