How to say "span" in Japanese

Choosing the right word
  • スパンCommon
    nounCovers a concrete, measurable span such as a length of time or the distance between supports. A loanword with a technical or quantified feel, it suits statements about how long or wide something is.
    The present perfect expresses the long span from past to present.
  • 広がりひろがりCommon
    nounRefers to the expanse or spread of something, emphasizing how far it reaches or opens out. Best when 'span' describes a spatial extent or the breadth of an area rather than a measured interval.
    He is the first national politician to be named in a widening corruption scandal.
  • 範囲はんいJLPT N3approx.Common
    nounMeans extent, scope, or range, so it fits 'span' when the emphasis is on the limits or boundaries of something covered, such as the range of a topic, activity, or area.
    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.
  • またがるJLPT N1approx.Common
    godan verb, intransitive verbThe verb for something spanning an area, period, or other domain, as when a bridge spans a river or a career spans decades. This is usually the natural choice when 'span' is a verb.
    台風たいふうの被害ひがいは数すう県けんにまたがっていた。↗
    The damage of the typhoon spread over several prefectures.
  • またぐJLPT N2approx.Common
    godan verb, transitive verbAlso a verb meaning to span or stretch over, though its given senses include bridging and saddling, and it is less specifically tied to the 'span an area or time' sense; またがる is typically the safer verb for that meaning.

Use 「スパン」 for a measured length or interval, 「広がり」 or 範囲 for extent or scope, and the verbs 「またがる」 or 「またぐ」 when 'span' is used as a verb.
