Poster presentation guidelines

For poster presentations at EPSC2026, we kindly request that authors follow these guidelines:

Submission

• Poster boards are in portrait format, suitable for A0 portrait posters. Posters will be attached using special materials at the information counter. Self-provided pins, needles, stronger tape, or similar (e.g. for fabric posters) must not be used as fixation material
• Virtual posters will be displayed on the EPSC2026 website throughout the duration of the conference. In addition, they will be displayed in the poster halls (printed in A3 format or larger) and should therefore also follow the standard A0 poster design. Virtual poster presenters must upload their poster pdf by Monday, 31 August 2026, 23:59 CEST as "Presentation file", otherwise it will not be printed in A3 and displayed during the on-site poster session.
• On-site poster presenters must upload their poster (pdf format) if possible before the start of the conference, but at least 24h before the start of the poster session as "Presentation file". Presentation files will be accessible by all registered EPSC2026 participants throughout the duration of the conference.
• Additional material, such as additional slides or a pitch video file (.mp4 file), can be uploaded as "Supplementary material". This material can be accessed on the abstract page, either open access (if marked as "public" during upload) or to conference participants only (if marked as "restricted").
• The presentation upload tool will open in mid-August 2026. Supplementary materials can be modified until Friday, 11 September 2026.

Poster style guide

• Your poster presentation should be in English and cover the same material as your abstract
• The poster must be self-contained and designed to be read: a bit more text can be added than would be appropriate for oral presentation slides.
• You are free to organize your poster layout as you wish, but a potential structure is as follows:
• Title/author details; abstract/overview of key results.
• Introduction, and necessary background.
• Methodology and results.
• Discussion, conclusions.
• Acknowledgements/references.
• The text should be clear and concise with correct spelling. Please use fonts that are clear to read (e.g. Arial, Calibri, or Verdana), and ensure there is good colour contrast between the text and the background.
• Prepare all diagrams or charts neatly and legibly beforehand, in a size sufficient to be read when standing 1-2 m from the poster board, including annotations (see notes on accessibility below). As a rule-of-thumb test, if you cannot read the text when printing your poster on an A4 sheet, it is too small.
• Links to web-based content are welcome.
• Make good use of colour to highlight different features within the text and charts.
• Bullet points and enumerated lists are easier to digest than large blocks of text.
• Authors can download a QR code from their abstract information page (magnifying glass icon) on the EPSC2026 website or from their conference abstract page. This QR code directly refers to the abstract page including (if used) online supplementary material.

Accessibility and readability

• The minimum font size you should use is 16pt.
• Use sans serif fonts such as Arial, Calibri, Verdana, or Helvetica that are easier to read.
• You should ensure that there is sufficient contrast between your text and the background (you can check this with online tools e.g. at: https://webaim.org/resources/contrastchecker/).
• Try to use colour schemes suitable for participants with colour vision deficiencies (e.g. red-green colourblindness). You can check this with online tools such as https://www.color-blindness.com/coblis-color-blindness-simulator/
• PowerPoint offers an in-built accessibility checker tool (Tools>Check Accessibility), which can draw attention to accessibility issues in your presentation.

Asynchronous discussion and advertisement

• To allow for asynchronous discussion and based on the positive feedback received during the last conferences, session-wide discussions will also take place on EPSC2026 section of the Europlanet Discord server. Please consider posting in the 'science-forum' about your research to start a discussion about your work.
• Please note that the Discord channel will only be accessible to EPSC2026 registered participants.
• You should also feel free to advertise your oral presentation via the social media hashtag #EPSC2026.

Public/Restricted settings for poster presentations

• Poster presenters need to upload their poster pdf as "Presentation file" (by Wednesday, 3 September 2026 for virtual participants and if possible before the start of the conference, but at least 24 h before the start of the poster session for on-site presenters). The material will only be accessible by registered EPSC2026 participants throughout the duration of the conference.
• In addition, poster presenters will have the option to upload their poster or any additional material as "Supplementary material" to be accessible beyond the poster session.
• This year, there is a third upload option for a 1-min poster pitch video file (.mp4-file). While this is mostly aimed at virtual poster presenters for a special screening of virtual posters in the poster area, we invite all presenters to upload a poster pitch to be linked to on their conference abstract page for more visibility during the EPSC2026 conference week.
• When you upload your poster presentation or other material as "Supplementary material", you will be asked to mark it as "Public" or "Restricted". We encourage you to choose the open access "Public" option, and it is likely that your presentation will receive more views.
• If your "Supplementary material" contains material that you do not wish to be shared publicly, you can choose the "Restricted" option. In this case, your material will only be accessible to registered EPSC2026 participants.
• Supplementary materials of posters will be available via the Copernicus website for the duration of EPSC2026 and on the archived site for one year afterward.
