I want to overline a piece of text, but the line is too close to the number, which is not nice, so I want to add some kind of padding between the overline and the text. This is what I've made up so far:


where XXX is the text I want to overline.

This looks very ugly for me, so I was wondering whether there is any better way to do it.

probably \overline{\strut XXX} (or make a similar different strut if that isn't the correct spacing, but strut is used in other places to get even vertical spaces) – David Carlisle Dec 19 '12 at 11:12

The following example shows some alternatives.

  • \raisebox can also be used to specify the final height (and depth). The height is known as \height that can be used for calculations (\dimexpr or package calc).

  • \vphantom: placeholder for height and depth of the argument. The argument is not set and the width is zero.

  • \rule with zero width can be used to insert an invisible vertical rule.

  • \strut adds a invisible vertical box with height .7\baselineskip and depth .3\baselineskip.

Example file:


  % Package `calc' can be used as alternative for `\dimexpr'.



\ov{XXX} \ov{xxx} \ov{\"A}

\ovA{XXX} \ovA{xxx} \ov{\"A} \qquad\verb|\raisebox{3mm}{}|

\ovB{XXX} \ovB{xxx} \ov{\"A} \qquad\verb|\rule{0pt}{3mm}{}|

\ovC{XXX} \ovC{xxx} \ov{\"A} \qquad\verb|\strut|

\ovD{XXX} \ovD{xxx} \ov{\"A} \qquad\verb|\vphantom{\"A}|

\ovE{XXX} \ovE{xxx} \ov{\"A} \qquad\verb|\raisebox{0pt}{1.2\height}|

\ovF{XXX} \ovF{xxx} \ov{\"A} \qquad\verb|\raisebox{0pt}{\height+1mm}|

\ovG{XXX} \ovG{xxx} \ov{\"A} \qquad\verb|\raisebox{0pt}{\height+1mm} + \vphantom{A}|

Very nice list, for all kind of different needs. I actually went the \strut way, but the \vphantom method looks very nice for longer texts – SztupY Dec 19 '12 at 18:07

The separation is controlled by a font parameter, so it's a bit difficult to change it. You can add a predetermined height to the text:


  \vrule height\dimexpr\fontcharht\font`\A+.1ex\relax width 0pt\relax


\textoverline{no} \textoverline{with}

Play with the 0.1ex dimension, trying various values until you're satisfied.
