I would like to place figures in my document in certain subsections. Normally I would achieve this with float using [H]. But this would mean, that the figures are at fixed points in my text and sometimes this just doesn't look good.

I already found this question: How do I ensure that figures appear in the section they're associated with?

How can I tell LaTeX use subsections as float barriers instead of sections.

The placeins package, with the section option, redefines \section. You might succeed with \usepackage{placeins} and

    \gdef\@fb@afterHHook{\@fb@topbarrier \gdef\@fb@afterHHook{}}}%

This will do the same the section option does, but for \subsection instead of \section.

Untested. On a side note, don't use [H]: it's a sure cause for problems in placing floats.

  • This solves my problem with the positioning, but it changes all my section/subsection numbering. – user31386 Jun 11 '13 at 13:00
  • @DaniWho Sorry, I missed doing a change. Fixed. The \section command should have been \subsection. – egreg Jun 11 '13 at 13:04
  • Note that this solution eliminates the \FloatBarrier in \section! It can happen that a float ends between a section title and its first subsection. To avoid this, you need to redefine both. – Luis Jul 29 '16 at 17:43
  • this can clearly be used also for subsubsection – Alessandro Cuttin Oct 10 '18 at 15:29

    @skan That happens if you call \usepackage[section]{placeins}. The answer tells you to call \usepackage{placeins}. – egreg Aug 18 at 20:16

If \subsection implicitely calls \FloatBarrier, then also \section should do it:


The following adds the implicit \FloatBarrier to \subsection:

  • Don't you mean "If \section implicitely calls \FloatBarrier, then also \subsection should do it"? – StrawberryFieldsForever Nov 4 '17 at 21:01

    @StrawberryFieldsForever No. – Heiko Oberdiek Nov 4 '17 at 21:17
  • I'm wondering whether or not we actually need all these expandafter commands... – Luc Evertzen Apr 24 at 12:13

    @LucEvertzen You will get an infinite recursion without \expandafter, when \subsection is called. – Heiko Oberdiek Apr 30 at 20:44
