It is recommended that oral presenters use the official BioLeagues PowerPoint presentation template which can be downloaded here.


1. There are varying presentation lengths depending on the type of session you are presenting in within the program. The common presentation length is 8 minutes/paper and 2 minutes for clarifying queries.

5.Invited speakers have 20 minutes in total, and they should plan to speak for about 15 min, leaving 5 min. for questions.

6. There is NO EXCUSE for exceeding your allotted time. It is a discourtesy to your audience, the Session Chair and the other speakers to take up more than your allotted time. The Session Chairs are instructed to adhere to the printed schedule for the session. With parallel sessions this is critical to the overall success of the conference.

7. We focus on knowledge sharing based on video, image and graphical presentations, which is why it is best if you synchronize your slides with your presentation to facilitate better understanding.


All presentations will be networked to the presentation rooms; therefore it is imperative that you ensure your presentation be loaded 30 minutes before your session begins as per the scientific agenda. This is because BioLeagues believes in using one’s time effectively or productively.

It will not be possible to use your own laptop or USB for your presentation.

1. Speakers should bring their presentation saved on a USB stick.

We also suggest that you to save your presentations into a “.pdf” format file.

Good Practices

1. Show no more than 1 slide for every minute of speaking time. This means approximately 10-12 slides are the MAXIMUM for a 10 minute presentation at the symposium. Remember, the last two minutes of the presentation are for questions from the audience. It is worth nothing that it detracts from the quality of the presentation to flash numerous graphs, equations, or tables on the screen, in rapid sequence, in an effort to squeeze a presentation into its allotted time.

2. We recommend that presentation formats of 16:9, 4:3 are also acceptable.

3. Make the letters on your slides BIG ENOUGH. The suggested minimum font size is 14.

4. Put no more than 12 lines of text or 4 curves on any slide.

5. Avoid lengthy tabulations of numerical data, and limit equations to those for which the terms can be properly defined.

6. Keep in mind that your audience needs time to interpret the data that you present.

7. When you display a graph or curve, inform the audience about what they should be looking for in order to grasp the point that you are trying to make. The audience will not have the time to figure it out for themselves.

8. Use repetition in your talk to ensure that the facts are understood by the audience clearly.

9. In addition to the main body of your talk, present an introduction as well as a summary or conclusion.

10. Include only information or data that can be properly explained in the allotted time.

11. Answer any questions that are posed to you.
