Determining Projection Screen Size?

[Rikk]

I have a room 40x40 with 40 people seated watching a PP Presentation. Is
there conventional wisdom on how big the projection screen should be for a
room and group size? Can someone point me toward a resource. I will need to
rent/buy the right screen.

Thanks.

I have to disagree with most of what the ASTD has said here. It encourages
people to stop thinking about what needs to be said in the presentation and
instead focuses them on following a set of (overly stringent) guidelines.

Since the original poster is looking for size information, I recommend they
check out this PPT FAQ entry:
How big should text be?
http://www.rdpslides.com/pptfaq/FAQ00125.htm

As to the other "guidelines", use graphics where they are needed and add to
the message. Use animations, sounds, movies, etc. in the same manner. Put
the amount of text on the screen that the participants can see and read
easily, without it distracting them from your message. Spend the time on
each slide that you need to in order to explain the content and get your
message across.

Want more? Check out my book: Kathy Jacobs on PowerPoint. I may not be the
ASTD, but I have been doing this long enough to know what works.

I need a resource, website, formula or advice on the physical size of a
projection screen in a room of give size and seating. Use of Graphics, Size
of Text and other design issues are not what I am looking for. I appreciate
your offers of information but I have ample resource for what you are
offering.

40" Inch is too small. The 60" I have is too small also. Before I rent or
buy, I would like to find out what size screen I need to accomplish my
purpose.

Thanks for the help.

Rikk,
I put this in the other post, but it was kind of buried. You should check
out this PPT FAQ entry:
Since the original poster is looking for size information, I recommend they

http://www.rdpslides.com/pptfaq/FAQ00125.htm

While the title talks about text size, there is information in that FAQ
entry on what is called the "8H" rule. It is a good way to figure out how
big hour screen should be.

A quick check of Google found these references also:

Post back and let us know if any of those get you further.
