How to measure

When my instructions say to knit until piece measures a certain lenght, do I count the stitches on my needle in the measurement or start just below the needle?

Thanks!

Just below the needle-- don’t include the “live” sts actually on the needle.

Thank you so much! That’s where I have been measuring from but for some reason it occured to me yesterday that I might be wrong!

Thanks for asking about where to measure from. That is a question I have had.
