When I do a edit->profile preferences in an xterm, I can then select
custom font in the general tab.
If I click in the font box, all the available fonts come up.
In that list is a font called Fixed Regular.
Is that the font?
There is a slider at the bottom of the font selection window that
allows for the selection of font size.  You should be able to adjust
that to 16, if it is available in that size.

The default seems to be monospace courier.

In fonts, *fixed* is often a synonym for bitmapped, as opposed to
vector fonts, where the shape is expressed as algorithms, and thus
scales with size.  So, fixed is an adjective, not a noun; there are
lots of fixed fonts, meaning the positions of the bits that create the
shape are absolute, and restricted to only that size.  Resizing a fixed
font creates jagged edges because the shape is resized as a block.
Like zooming in on a jpg or png.
