How do I read 数 in ページ数?


ページ数 means number of pages. Is it すう or かず?




「ページ数」 is always read 「ページ **すう** 」.

**_Generally_** speaking, 「数」 is read 「かず」 when preceded by originally
Japanese words, and it is read 「すう」 when preceded by Sino- and Non-Sino
loanwords. Be reminded that exceptions abound regarding this matter. When
unsure, consult a dictionary or call me collect.

> **「かず」:**

「[口数]{くちかず}」(talkativeness), 「[場数]{ばかず}」(number/amount of experience(s) ),
「[品数]{しなかず}」(number of items), etc.

> **「すう」:**

「ホームラン数」(number of homeruns), 「[台]{だい}数」(number of machines, cars, etc.),
「[支店]{してん}数」(number of branches for a company), 「ゴール数」(number of goals in
soccer), etc.

> **_A Hillarious Exception:_**

「[頭数]{あたまかず}」: The number of **_people_** in a given place or situation.

「[頭数]{とうすう}」: The number of **_(larger) animals_** in a given place or
situation.




It is read すう in this case
