I'm creating a figure using LyX. I would like the spacing of the caption below the figure to be 1.3. Is there an easy way to accomplish this? Setting the spacing to 1.3 for the entire document using the setspace command doesn't seem to work.

    Adding \linespread{1.3}\selectfont{} in an ERT within the caption, is that what you mean? May 10, 2013 at 17:11
  • That's perfect. One other question: Is there any way to change the font size to 11.5?

  • \fontsize{11.5}\selecfont{}

  • By the way, \begin{centering} is wrong: just use \centering and remove \par\end{centering}

Unless the exact value of font size is very important, you can use the features of the caption package. (If it is, see Old answer below.)

Go to Document --> Settings --> LaTeX preamble, and add


If you want to change all the captions in your document to a larger font with added linespacing, add the following line to the preamble as well:


or if you want it to apply to tables only,


caption allows you to customize your captions a lot, see the manual for details.

If you want to apply this to just a single caption, add an ERT within the table/figure float, before the caption, and write the \captionsetup there.

Old answer

I'm not sure why you want this, and I wouldn't do myself, but if you're doing this for a single caption, you can add an ERT at the beginning of the caption containing


To change the font size as well, use


The second argument to \fontsize is the baselineskip, set to 1.2 times the font size.

This does not, however, change the size of Table 1. To change that you can use the caption package, as explained above, and use labelfont={large}.

    @user30501 Instead of snippets of tex code, Please include minimal working example (MWE) starting with \documentclass{...} and ending with \end{document} in this way we know the full information including class. May 10, 2013 at 22:54

    When using the caption package anyway one could use that package to setup the line spacing inside captions (globally), too, so there is no need anymore to change every single caption.

  • @AxelSommerfeldt Excellent point, I'll edit my answer. May 11, 2013 at 8:50

In order to make @Torbjørn T. code function correctly, it is extremely necessary to load the setspace package in your preamble (and of course, copy the setspace.sty into the /texmf folder). This is due to we are using the stretch option in the \captionsetup declaration.

Of course Caption Package can change caption's line space, with the stretch option, but it is necessary to load both caption and setspace packages. (Page 38 from: http://osl.ugr.es/CTAN/macros/latex/contrib/caption/caption-eng.pdf )

So, the code would be:


Otherwise, only making:


would not function.

  • setspace inclusion made the difference. Thanks.
