I'm using the ulem for strikethrough, but need two formats of strikethrough. I'm currently using \dout{text} which looks good, but the second\xout{text} makes the base text a little too unreadable.

I'm looking for a clean double-strikethrough... the closest I've gotten is:

\newcommand\dout{\bgroup \markoverwith{\rule[0.2ex]{0.1pt}{0.4pt}\rule[0.8ex]{0.1pt}{0.4pt}}\ULon}

but this creates a slight hatching effect. (It's good enough, but I figured I'd see if any of ye clever folk had a cleaner solution.)


  • Just a note that when I use the above \dout command, it doesn't work in captions, and it looks a bit faded compared to \sout (rule weight doesn't quite help). – badroit Oct 2 '10 at 23:46

This is modified from the double underline macro of ulem (note that \MakeRobust is also defined by that package):

 {\kern-.03em\vbox{\hrule width.2em\kern0.45ex\hrule}\kern-.03em}}%

and seems to work quite well:


  • Works a treat, thanks! A small problem in that it doesn't work in captions ! Undefined control sequence... \markoverwith ...ULC@box } \else \def \UL@leadtype ... and then ! Tex capacity exceeded, sorry [input stack = 5000]. \UL@on 1->\leavevmode ... but not a problem for my case. – badroit Oct 3 '10 at 0:45
  • That (and a scaling problem) should be fixed now. – Caramdir Oct 3 '10 at 0:48
  • Hmmm... addition of \UL@setULdepth gives me an Undefined control sequence. for every use of \dout (inside or outside captions). \MakeRobust seems fine. Is \UL also in that package? – badroit Oct 3 '10 at 0:55
  • \UL@setULdepth is also from the package. Maybe you forgot the \makeatletter? Actually, that command was just a copy&paste error any you can remove it. – Caramdir Oct 3 '10 at 1:32
  • Better \DeclareRobustCommand instead of \def, and avoid \MakeRobust. I suppose this answer got \kern-.03em after the other answer was entered. – Donald Arseneau Jul 13 '20 at 8:08

More an observation, then an answer, but too long for a comment: The effect dependens on the pdf viewer:

This is Evince (300%, 400%): evince 300 evince 400

It looks better in Acrobat (300%, 400%) acrobat 300 acrobat 400

At least until you zoom in really close (1600%):

acrobat 1600

How does it look when printed?

  • Good point. Was using SumatraPDF which looks similar to Evince above. It does look better on Acrobat. Printed, both look solid... though Acrobat a little more so (in fact a little too solid, making the text a little unreadable). – badroit Oct 3 '10 at 0:41

I think Inserting \hskip-0.1pt in the first proposed code solves the problem of hatching.
