This question already has an answer here:

Instead of 'III' (three 'I's), I want the numbers to look more like those in the attached image. When using Computer Modern font, is it possible to just remove the horizontal space between letters? a previous post worked around this by defining a new command using /makebox, but some of the dimensions used absolute length units and therefore is not a solution for different fonts, especially when you want to use this in subscripts or superscripts.

    Which font are you using? – Sigur Jan 31 '18 at 19:05
  • To get that sort of effect easily, you will need a typeface that has roman numerals correctly spaced. The only freely available typeface that has them (that I know of though there may well be others) is the Brill typeface available at brill.com/about/brill-typeface/…. – sgmoye Jan 31 '18 at 20:01
  • the font you show is a "condensed" font -- letters are much narrower than the usual "book" type. even applying negative letterspacing, the result will not be quite comparable to what you are showing here. – barbara beeton Jan 31 '18 at 21:42

You can insert a negative space between two characters:

I \RomanI

II \RomanII


IV \RomanIV

V \RomanV

VI \RomanVI



IX \RomanIX

X \RomanX


The above should work with all font switches (\tiny, \scriptsize, \footnotesize, ..., \Huge). You can adjust the spacing as needed, if you want them closer together/further apart.

microtype's letterspace package also provides \textls that you can use (the starred version):

The following defines two macros. The first is \tighten which reduces the space between every letter of its argument by a given length (by default 0.25ex). This is intended for manual insertion of roman numerals.

The second is \TightRoman which uses \tighten to set a counter with tightened Roman numbers.


  \if\relax\detokenize{#2}\relax% detect empty argument
  \ifx @#1%

I think this post solved my problem: Enlarging tracking (= letter spacing)



gives the desired results.
