You've lost me there, I was thinking it was the width that varies. It seems like you have it all worked out though. It can get confusing because you are dealing with distances on paper, not the acutal globe. A Mercator projection appears as a rectangular based grid system so as you get closer to the poles the actual distance between lines of longitude shorten on a globe but the width between longitudinal lines on paper remains constant. The land graphic underneath is stretched to fit. That's why Greenland appears so much larger on a Mercator projection than it actually is. Its been "stretched" to accomodate the constant width paper longitudinal lines. Chez
