Generate Points Along Line placing points at incorrect distance

VictoriaTousaw

I am trying to generate points along a line that are spaced 100 m apart with points at each end of the line. 

I am using the Generate Points Along Line tool, by distance, 100 meters. The output results in points along the line that are placed ~145 m apart in straight sections of the line, and ~115 to 130 m apart around curves in the line. I double checked and the line is all one segment. 

Any ideas of ways that I can try to fix this are greatly appreciated!

Are you using the measure tool to confirm the placement? and is your map coordinate system set to the web mercator?  If so, choose a projected coordinate system that shows better distance and area measures (like a UTM, state plane, equidistance etc(
