Landscape against portrait posters
Portrait suits a study with a lot of text and a narrow board, because a tall column is comfortable to read and the reader walks down it. Landscape suits a wide figure, a participant flow beside its results, or a four column reading order. The deciding factor is usually the stand the conference provides, not taste.
Most people pick the orientation they have seen before. The better question is what your one most important figure needs, and what shape of board the venue actually has.

| Portrait | Landscape | |
|---|---|---|
| Reading order | Down one or two columns | Across three or four columns |
| Suits | Text heavy studies, narrow stands | A wide hero figure, side by side comparison |
| Flow diagram | Fits down a column naturally | Sits beside the results it explains |
| Risk | A long thin column of prose | A reader losing the thread between columns |
| When unsure | The safer default in most venues | Only when you have confirmed the stand |
Let the hero figure decide
Most posters have one figure that carries the finding. If that figure is naturally wide, a trend over time, a comparison of several arms, a map, then landscape gives it room and the rest of the board arranges itself around it. If your key output is a table or a flow, portrait usually reads better because both are tall. Choosing the orientation before you know which figure matters is how boards end up with the result squeezed into a corner.
Reading order changes with the shape
On a portrait board a reader goes down, and columns are read fully before moving right. On a landscape board they scan across, which means the leftmost column has to establish the study quickly or they drift to the middle where the pictures are. That is why landscape boards benefit from headline numbers near the top centre: they catch a reader who started in the wrong place.
Ask the organiser, then design once
Board mounting is a venue fact, not a preference, and it is a one line question in an email. Designing for the wrong orientation and rotating later does not work, because the two shapes have different aspect ratios and different natural column counts. Confirm first, then build, and keep a quiet margin inside every edge in case the stand is smaller than advertised.
Questions people ask
Which is more common at conferences?
It varies by field and venue, and neither is safely assumed. Clinical and life science meetings lean portrait; some engineering and computing venues lean landscape. The call for abstracts usually says, and when it does not, the organiser will answer within a day.
Can I make one design work in both?
Not well. The aspect ratios differ and so does the column structure, so a genuine conversion means relaying out rather than rotating. If you really need both, build the one the conference wants first and treat the other as a separate piece of work.
How many columns should each have?
Portrait works with two or three; landscape with three or four. More than four on either and the columns get too narrow for a chart, which is the block that suffers first. The number of columns should come from how many sections you have, not from filling the space.
Where should the key numbers go?
High and central on both, immediately after the abstract. A reader who stops for three seconds should leave with the finding, and that only happens if the number is above the fold and set large enough to read from a metre.
Does orientation change how much text fits?
Not really; the area is the same. What changes is how that text reads. The same thousand words feel longer in one tall column than spread across three shorter ones, which is a reason to prefer more columns if your board is text heavy in either orientation.
