Speaker instructions


  • The screen dimensions at the Rotterdam Hall are 16:9 and in all other sessions rooms 4:3, so please carefully check on the conference programme where your presentation takes place, select the right setting for your presentation and then save it.
  • The only accepted formats are PowerPoint or PDF.
  • The use of your own laptop during your presentation is NOT possible. A technician with a computer (MS-Windows operating system) in the back of the room controls the presentations where you will handle a remote control to step through the slides.
  • If you are showing a video, please make sure to embed this in your presentation.

General tips for your slides

  • Keep visuals clear and simple.
  • Use a minimum of words for text and title frames. Five to eight lines per frame and five to seven words per line are the maximum – less is better.
  • Avoid the overuse of too many colours, patterns and graphics in one frame. In particular, mind the colour-blind.
  • Contrasting colours work best. A good rule of thumb: use a dark background colour with lighter colour for text and graphics.
  • Avoid intensely bright or saturated colours that compete with the text.
  • Keep colour scheme consistent throughout your presentation. Changing colours and type styles can be very confusing and distract from your message.
  • Use standard Windows fonts only, 24 font sizes can be read easily.
