The p2 is usually constructed on a laptop or desktop computer where the final slide size often fills the screen. The size of font is reduced as more and more detail is added. What may appear clear and legible on a computer screen is not the same when projected at the event.That is not the time to ask, “can you see this at the back?”
This is a standard powerpoint slide with the fonts describing its size. Most of it is easily read on your device, although the last line less so. To put this in context though the 2nd line is the Template TITLE size (44), the third is the top bulletpoint line 32 and fifth level indent on the template is 20. The last line is the font size most presenters add references at.
I presented recently at the Northern Emergency Medical Conference. This was held in an hotel and the screen provided was 2m tall. This is how it appearsfrom 3/4 of the way back in the auditorium. “Can you see this at the back?” is a reasonable question to ask but arriving at the conference centre is usually too late to be making major changes to your p2.
How then might a presenter prepare for this? Use the zoom function on the presentation software. To overlay this the software has zoomed to 10%. If it is not possible to view this on the computer at that resolution they won’t be able to see it at the back of the room.
Even with a screen twice the size, which would be fairly significant for any theatre, this is set at 20% zoom on the software.
The slide on your computer is NOT the slide the audience will see. Like so many things in life, size matters. To aid in preparing the p2 consider how it will be viewed at twenty per cent zoom, this will be likely what the audience will see in a moderate size room with a moderate sized screen. Never use a font less that 44. “Can you see this at the back?”
