many word processors and text-formatting systems include an option to format text in caps and small caps, which leaves uppercase letters as they are, but converts lowercase letters to small caps. how this is implemented depends on the typesetting system; some can use true small caps glyphs that are included in modern professional font sets; but less complex digital fonts do not have a small-caps glyphs, so the typesetting system simply reduces the uppercase letters by a fraction (often 1.5 to 2 points less than the base scale). however, this will make the characters look somewhat out of proportion. a work-around to simulate real small capitals is to use a version of the small caps generated by such systems, to match well with the normal weights of capitals and lowercase, especially when such small caps are extended about 5% or letter-spaced a half point or a point.
