You can use "away from", too.
I'm only 4 pages away from finishing the chapter.
I encountered the 1st one just like 4 pages away from the beginning, and since then it's been NON-STOP typos.
I am about 3 or 4 pages away from finishing “sex drugs and cocoa puffs” by chuck klosterman.
Or use "2 pages to go"
Jeremy and I have figured out the rest of issue 3, and it looks like we only have 2 pages to go!
But actually, the first one has more Internet hits, so it's more common.
