Unless you have line breaks (scene breaks) every page should have the same number of lines.

Otherwise, don't worry if your last page has only two words on it (The End); just post it.

Where this is done depends on the version of Word you use, but in Word 2007 (Windows) you get to it through the Modify Style dialog, which you reach by right-clicking on the style you use for standard paragraph text:

From the Modify Style dialog, click the Format button (lower left corner), then select "Paragraph..." In the Paragraph dialog, Spacing section, set the "Line spacing" option to "Exactly" and the "At" option to "24pt."

1) I think you need to select the text you want to remove this feature (perhaps the whole document in this case).

2) Click on Format in the menu then Paragraph.

3) Click on the Line and Page Break tab

4) Uncheck the "Widow/Orphan control" check box.

I don't know if this is what you're looking for but it is another option to look into.

According to MS Word Help: "A widow is the last line of a paragraph printed by itself at the top of a page. An orphan is the first line of a paragraph printed by itself at the bottom of a page."

So if the last line of a para would be at the top of a page by itself, Word will move the second-last line of the para to the next page so now that page has the last two lines of the para at the top. The previous page will now be a line short.

If the first line of a para would appear at the bottom of a page by itself Word will start the new para at the top of the next page, and the previous page will be a line short.

If you switch this feature off, you might or might not have two lines at the end of the piece, and there will almost certainly be some widows and orphans elsewhere. They're generally regarded as bad things because they disturb the reading flow:

Also, if the changes you make to the formatting get saved in the "Normal" template, they may affect other documents that you or others you share the computer with have written.

I'd leave it alone. I have played much with formatting in Word. That way lies madness. I would suggest either mastering the formatting features by studying one of those fat books on Word, or letting Word do its thing automagically. Nobody is going to reject a story because the last page holds just two lines.

(If you mess with the line spacing as has been suggested, and if it works, that will be because there is no start or end of a para near a page break; but then, if you add or delete lines subsequently such that the start or end of a para does fall close to a page break, widows and orphans will kick in and you'll be pretty much back where you started.)

I think we're all struggling with this because there's really no way to guarantee the same number of lines per page without risking widowed and/or orphaned lines. Lots of trade-offs in formatting, and Microsoft has made the whole thing much more complex than it needs to be, IMO.
