Original X is oficially 160 cm or 34 pixels tall. Which means each pixel is 4.71 cm.

In X1 Zero ir 40 pixels, making him exactly 188.2 cm tall.

In X2 and X3 his new body is 44 pixels or 207 cm tall.

From X4 to X6 we can assume X was somehow upgraded, since he's taller. Or Zero height was reduced for combat dynamics, but let's stick to the former scenario:

Zero: 46 pixels = 207 cm 1 pixel = 4.5 X: 44 pixels = 198 cm

I've made a chart with some Mega Man characters:
