The answer, of course, depends on the context in which you're asking this question.

If you're asking this question relative to a minimum-page-number requirement, then 3 lines is not enough. If a professor asks for a 4-page essay, and you turn in 3 pages plus 3 lines on a 4th page, the professor would likely mark you down for not turning in at least 4 pages. To meet a minimum-page-number requirement, I'd argue that you need at least half the page filled to count as a page.

If you're asking this question relative to a maximum-page-limit requirement, then I'd say that 3 lines is 3 lines too many. In the context of limits, a page is a page--it does not matter how many lines is on it if you go over the limit.

If you're asking this question relative to the aesthetics of publishing, then I'd say 3 lines is enough. There's no need to meddle with margins or edit out words in order to get everything on the prior page. Three lines is enough to justify printing out an extra page.

I hope this helps.

I find the question difficult to comprehend. As phrased, it sounds like you're troibled by an insufficiency of length, yet from Day One of law school, fitting an argument within the page limitations was always the problem, not stretching the argument to meet them. Which is why my school had strict maximums on the number of lines per page and even the number of characters per line.

If your problem is, indeed, that you're three lines over, then yes, it does count as a page. I usually solved this problem by the judicious replacement of key words with shorter ones. It's amazing how many lines you can save by altering where the lines wrap early in a paper.

In any event, good luck. The last few extra lines are always the toughest to trim down.

How many lines DO there need to be. DO, not does. Thanks.

How many lines do a haiku have?
How many lines do this computer program contain?
How many lines do each stanza have?
How many lines do it make?

How many lines do it take for me to figure out you've no clue what you're talking about?

Lines is a funny word; although it appears to be plural, it is often treated as singular. This is especially true of lines of text. Lines of coke are a whole different story (e.g., "how many lines do I get in an 8-ball?" is correct).

Hmmm. I don't think it has anything to do with "lines."
How many lines do I need?
How many lines does he need?
It's whether the object of do/does is first, second, or third-person. I think. So what's "there"?

I've no idea. I was never forced to diagram sentences. But you are probably right. I was thinking of lines in a discrete v. total sense. I actually think either do or does works with there.

Reading about all of these lines I never realized it was such a big deal! It was always my belief that a line is a line. In school if they said write a 1 page report then I madea sure 1 page was pretty much filled. If the paper was limited to 1 page then I would make sure it was. However if it was something more artistic or creative such as a theology class then I guess just 3 lines may be right.

I never thought lines!

Intestingly enough, I came across one answer to this metaphysical quandry.

Article Nine, rule 6, of the rules for the ABA Law Student Division for the 2001-2002 NAAC provides:
"Any partially filled page will be counted as a full page."
I guess even one word over would count.
