In English, I can write "At x pages, y." where x pages refers to a document consisting of x number of pages and y is a description of the document. Example: At two pages, the proposed bill is short.
The Chinese equivalent of "at" is "在", however it applies to locations. "Pages" isn't a location in this case, so what would I write to convey "at" here? Or can I use "at" as I do in English?
My best guesses (using the preceding example) are "在兩頁，法案很簡短" and "包括兩頁，法案很簡短", but it's not clear to me whether either is correct.
