I guess you have to find the nearest entry matching your desired size
in the font’s available_sizes.

The following Python code from my font_chart example
<https://github.com/ldo/python_freetype_examples> doesn’t choose the
right size, it just picks the first available one. But it at least
shows you the right API calls:

    if len(show_face.available_sizes) != 0 :
        # fixme: quick hack for bitmap fonts
        sys.stderr.write("available_sizes = %s\n" % 
repr(show_face.available_sizes)) # debug
        use_size = show_face.available_sizes[0]
        show_face.set_pixel_sizes(use_size["x_ppem"], use_size["y_ppem"])
    else :
        show_face.set_char_size(size = textsize, resolution = freetype.base_dpi)
    #end if
