Standard poster size should be: A1 format (Width:594mm x Length:841mm).
Posters must be oriented vertically. Remember not to make the font size too small. If making your poster in PowerPoint, a font size of no smaller than 18 pt is recommended.
Posters should all have a title which should be matched the Abstract.
Only use main points for your poster:
Introduction/Description
Theory/Experiment
Conclusion/Summary
Posters should contain mixture of text and visual content (photos, pictures and graphs as appropriate). Make sure your photos are a reasonably high resolution: 15cm x 10cm (1800px x 1200px) @ 300dpi (dots per inch).
