How to create an icon font in inkscape?

Question

Design

I'm trying to create a font in inskcape, I ran into one problem, in all the examples that I have not met, everything is fine, I can not identify the cause.

The glyph should take up the same space as the square, but it takes up a very small area, which makes the font look wrong. Unit measurements in pixels, canvas as elsewhere 1000 by 1000.
Help me figure out the reason.
a couple of examples for comparison:
