You do lose a bit of height, but only a tiny bit, in the range of a few millimeters.

Thomson uses the same post, and makes a bend of 10-15 degrees or so (never measured it) 4" or so from the top, so there will be a drop, but it will be less than 0.10" (cosine of the angle x 3").

Hopefully, you're not at a height where that would make any practical difference.

BTW- if the math is an issue, ypu can sketch it out. Use a ruler and make a mark 4" up the edge (height of straight post to bend). Draw a reference line inward & make a mark 16mm (3/4") for the offset. Draw a line from there back to the bottom corner to make a triangle. Measure 4" up the new line, and see how far short of the reference line it comes. That's the drop.
