I've seen scattered threads about this throughout the forum and it must be a tired question by now, so forgive me for asking yet again.
However, I'm wondering if someone has put together a table or matrix of file sizes (ex: Large - FINE, Large - TIFF, Large - RAW) and corresponding maximum acceptable print sizes (ex: 8 x 10, 16 x 20 ..) at 300 dpi.
Actually, I'd like to qualify "acceptable" as acceptable by professional portrait standards. I'm sure the answer isn't as clear cut as client requirements vary, but I'm hoping to use the matrix or table as a general guide to avoid shooting a smaller file size with expected larger print output. I'd like to be able to shoot the large file size for important pics and shoot lower file sizes for shots I know I won't be enlarging (web/e-mail shots), thus maximizing use of my CF cards.

I shoot all my photos in RAW (uncompressed) and ssimply reduce image sizes for web / email use later.
The NEF RAW shots have been blown up to 8 x 10's and are looking very crisp and clear, I think 16 x 20 would be OK as the print is so good at 18 x 10.
Interestingly JPEG medium print out crisp and clear on 7 x 8's.
My digital printing is done by a lab, but my photo quality printer seems to kick out very sharp prints too.

Although made with film in mind, this may help a little.
Have a great time :-)

well, I primarily shoot RAW images only. My thoughts are to not throw away any information. After all, I paid so much for the camera to get that information. I then decide after the fact how I want to store the image... Is it a sellable print, or a family photo. That dictates if I store it as an 16bit TIFF or 8 bit jpeg.
I have personally taken images and blown them up to 20x30 at 200ppi, applied an unsharp mask and had excellent prints on a Professional lightjet printer. The ideal size for me is a 16x24 though.
That is my two cents.

For the absolute best possible print shoot in RAW and don't interpolate pixels. Print a file sized to 300 dpi without interpolation. Beyond that it is all subjective.
I use RAW and assume I can get an 11"x14" print. Note: this does involve some interpolation.
