Hi Jillie. You have to do the math here. I happened to be looking at a book of building codes today, for the BNSF Railroad. It stated that ties per mile for main line track was 3,700, and the ties for yard tracks and sidings were to be 3,200 per mile. What's funny here is, while I was reading this book of track codes today, I thought why am I doing this? And then 4 hours later, you asked your question.

Depends on what the track will be used for (heavy mainline vs. yard vs. urban transit), the quality of the ties (softwood vs hardwood vs concrete vs metal), and the tie spacing that's already there.
For instance a downgraded branchline might merit 21" tie spacing, but if it's already been laid 18", that's what you'll be using unless you're completely replacing a long section of track.
20" is common for wooden ties, 24" for concrete.
Concrete ties are usually spaced farther apart than wood ties.
Mainline have closer ties than branch lines, yards, and urban transit lines.
New ties cost about $50, so they install no more than needed.

Wooden ties center to center is 18-20" and I think they put concrete ties at 24" center to center.
