Presenter Guidelines


  • Plan your talk for 20 minutes (invited speakers) or 12 minutes (for promoted posters) to allow time for a 5-minute (invited) or 3-minute (promoted) question period. Well-known guidelines for preparation include: planning one visual per minute and limiting the content to one idea per visual.

  • There will be an ENC Speaker PC and MAC (with the latest OS and software) on stage for presentations.  Please bring your presentation on a USB drive at least 30 minutes before your session and load it onto one of the ENC Speaker laptops.  You can even load your presentation the day before your session, the earlier the better!  Just make sure you tell the AV technician which session you are in.  You can use your own laptop as a last resort.

  • The aspect ratio of the screen will be 16 x 9.

  • Because of licensing requirements, only True Type versions of the normal Mac/Windows system fonts and the free Microsoft fonts (“Microsoft's core fonts for the Web”) are reliable. For a complete list of these fonts, see PowerPoint permits "font embedding" for other fonts, but use this with caution; character and line spacing are not always preserved. 

  • Be sure that any graphics and equations are inserted as jpeg or gif pictures at appropriate resolution. 

  • Avoid inserting scanned pages reduced to a small rectangle which may occupy so much memory that it displays as a red X in PowerPoint (if the ENC computer has less memory than yours); a Kaleidagraph figure legend or MathType equation may be garbled.

  • If your presentation does not use animations, Acrobat pdf files are also an option, and in this case font embedding is reliable.

  • Either a light or a dark background will give acceptable results, but switching back and forth between the two can be distracting for the audience.

  • For legibility, use a sans serif font such as Arial, 32 pt or larger; maintain a one inch margin on all sides; and use high contrast colors.

PRESENTATION. Project your voice as if you are talking in a mid-sized conference room. It is much easier to reduce the audio system gain for a loud voice than to increase it for a quiet voice. Please use the laptop mouse for pointing, rather than looking around with a pointer at the projection screen.
