In the papers I read the caption in figure floats is placed below the figure and in table floats the caption is placed above the table.

I recognize that this is a common style that a lot of people recommend.

But what is the reason behind this difference?

    Interestingly, the style guide I use (New Hart's Rules) refers to them by different names: it speaks of figure captions and table headings. I don't know if this is common usage in English (not a native speaker).

It has to do with the way people absorb printed information or, more accurately, how readers of Western texts are acculturated into this.

Tables are textual devices and are, to some or other approximate degree, structured to be read in the same left->right, top->bottom order (*). To this degree, they therefore do not differ in important information processing ways from the body text. Normal text (not, e.g., poetry or other intentionally disruptive forms) is ordinarily structured in a "pyramidal" form: general and introductory concepts are best placed at the beginning, with increasingly fleshed-out details placed later on. The reading eye that saccades across text and the brain that controls it has learnt beginning at the age of two or whatever to most efficiently gather (Western) textual information in this way. By our age, we cannot not process text this way.

Graphics, on the other hand, are iconic. The eye does not scan pictures for information in remotely the same way (in fact entirely different cerebral systems are in charge of gathering and interpreting textual and graphical information - you can knock out one part of the brain and impair one system without noticeably affecting the performance of the other; see, e.g., almost any popular writing by Oliver Sacks). It would be almost impossible to prevent the normal human brain from scanning and interpreting, no matter how briefly, a picture on the page before forcing it to reading the caption (no matter where the caption is placed because by that time the attentional mechanisms in the part of the brain that is now switched on is directing the eye to saccade in non-linear sequences).

So, to answer your question, good typesetting sets out to provide readers the most productive (rate of information processing for expended effort) reading experience that it can. For text: the caption summary is placed above the details to fit in with linear eye saccades and the pyramid principle of text interpretation; for graphics: the graphic is placed first to fit in with quite different attentional control mechanisms, non-linear eye saccading and non-linear information processing.

(*) Factor in acculturation. Good typesetting for R->L or bottom->top reading orders will follow these general principles (for biologically human species (**)), leading however to different outcomes.

(**) The point is that it's our brain biology that has ultimately led to the development of these rules. Here's something to think about: what are the optimal typesetting rules for non-human species, e.g., maybe sapient machines, or echo-locating information gatherers like bats or porpoises. Where would they like to "see" their captions? :))

    Wow, great answer. Now, the 2^16 dollar question: did the people that set out the guidelines know this themselves? Commented Sep 19, 2010 at 5:43

    Nice! This said, like all rules I think it needs to be applied with some thought rather than as an absolute law. Despite the "textual" basis of tables I'm not 100% convinced that they don't excite some of the same cortical response as pictures. And there are also issues of confusing caption ownership, which I think should be allowed to trump this rule if there is danger or reader confusion. Commented Nov 26, 2013 at 13:51

    Should you put listing captions above aswell? Commented Dec 12, 2017 at 5:46

I can't pinpoint the source, but reportedly readers will first comprehend a figure as a whole and only then study its caption (so the caption is placed below the figure), whereas they will first look up a table's caption in order to fathom out the table data (so the caption is placed above the table).

EDIT: Source relocated -- Joachim Schlosser, Wissenschaftliche Arbeiten schreiben mit LaTeX, 3rd ed., p. 101.


A figure only ever fills one page (or at most a double page spread). A long table may extend over several pages, and you don't want your readers to have to page ahead to find the explanation of what the table is about.

    This explains why table captions are placed above the actual tables, but not why figure captions are treated differently.

    This is a good point, but I think it would be better suited as an addendum to one of the other answers.

In tables, the columns are usually labelled at the top, above the content (much in line with Geoffrey Jone's answer). As the column labels are usually the first thing a person looks at in order to understand the table, it makes sense to put the caption above of this.

The same principle applies to figures / plots. Usually the most important axis labels are at the bottom, on the x-axis. Again, the description of the figure (the caption) and the definition of the content (the axis labels) are kept close together.


I was wonder this same thing (but reversed, ie, why don't figure captions go above like I would expect). I don't know why or how this convention came about. Maybe its because tables have "titles" but figures have "captions". In any case, I think "captions" would be better placed above figures. As a reader, I would like to read the caption (ie, title) of the figure to know what is about before I look at it. The idea that a reader is supposed to process the figure first, and, then after finishing processing it (or maybe realizing that they don't understand it), then read the caption which explains the figure seems backwards.

Even it is true that a reader will ignore the title (no matter where it is) and go straight to the figure, when the reader is ready to read the title, the natural place to look for it is above the figure, not below. We read top to bottom; we expect the title of something (book, chapter, section, table, figure) to go above (before) the thing, not below (after).


The table caption serves as a title for the table. Traditionally, figures have titles within them, so the caption goes below.
