UK Conference Poster Sizes: What 18 Conferences Ask For
Quick answer: Most UK conferences ask for an A0 portrait poster (841 × 1189 mm). A few ask for something different: the British Sociological Association wants A1 landscape, BERA wants posters no larger than A0 in landscape, and the British Thoracic Society Winter Meeting wants A0 landscape. Always check your own conference’s guidelines, because rules change from year to year.
We checked the official poster guidelines of 18 UK conferences and society meetings across science, medicine, nursing, education and the social sciences. The table below shows what each one asks for, with a link to the source so you can check the latest version.

What the guidelines have in common
- A0 portrait is the standard. 14 of the 18 conferences ask for A0 (or no larger than A0), and most of those want portrait.
- Landscape is the main exception. The BSA, BERA and the British Thoracic Society all ask for landscape. A portrait poster may not fit their boards.
- Smaller events often ask for A1. Workshops, departmental days and some social science events use A1 or A2 to fit more posters into a room.
- “Not larger than” means exactly that. Several conferences say oversized posters will not be displayed.
- Many need a PDF as well. BMUS, BAPEN, BERA, the British Thoracic Society and others ask for a digital copy for their app or online gallery, so keep your final PDF.
- Check how posters are fixed. Some boards need Velcro that you bring; others provide fixings and ban pins.
Some conferences now use e-posters only
A few medical events have replaced printed posters with screens. The RCGP Annual Conference 2026 shows ePosters on large portrait screens, and the Association of Anaesthetists Annual Congress displays ePosters in the exhibition hall. If your conference uses e-posters, you will usually be sent a template after your abstract is accepted.
How to check your own conference
- Find the poster guidelines page or PDF on the conference website. It is often under “Abstracts”, “Presenters” or “Programme”.
- Note the size, orientation and any maximum dimensions of the board.
- Check whether you also need a PDF or e-poster, and the deadline for sending it.
- Check how posters are fixed (Velcro, pins or provided fixings).
- If the guidelines give a board size instead of a paper size, choose the largest A-size that fits with a small margin. Our poster size guide lists every A-size in mm, cm and inches.

Frequently asked questions
What size are most UK conference posters?
A0 portrait (841 × 1189 mm) is the most common size. Some conferences ask for A1, and a few ask for landscape, so always check the guidelines for your event.
Can I print an A0 poster in landscape?
Yes. A0 landscape is 1189 mm wide and 841 mm high. Some conferences, such as the British Thoracic Society Winter Meeting and BERA, ask for landscape. Others accept portrait only.
What if the conference only gives a board size?
Choose the largest A-size that fits the board with a few centimetres to spare. For example, a board 1 m wide and 2 m high fits an A0 portrait poster.
Do I need a PDF as well as a printed poster?
Many conferences now ask for both: a printed poster for the board and a PDF for their app or online gallery. Keep the same PDF you send for printing.
