I've been asked a question that I don't really know the answer to (and that doesn't happen often). ;)
With the Canon 20d, 8.5 megapixal...
How large can you make the prints before they start to lose quality?
Help me look like a genius. haha

For photo quality prints, you generally do not want to go below 150 dpi (dots per inch).
3504 x 2336 is the resolution of a 20d at maximum size.
23.36" x 15.57" is the suggested maximum size of print from that image. |

It would help if you'd post the image dimensions, and not the product (8.5MP).
However, you should be able to print a 20x30 with no problem. Divide the number of pixels in your finished image by 150 to get its size for "good" quality; divide by 300 for "excellent" quality. |

Hmm ... so sounds like about 16x20 or 18x24 ... although I know people print larger than that -- careful upsampling and subsequent sharpening is probably in play there ....
Now, I've printed a 20x30 from a 2MP camera (see below), and it looks OK from 3 feet away -- it was taken in the dark and so was pretty noisy anyway.

Thanks guys!
I was just offered an opportunity but they need prints that are very large for display purposes. I didn't want to take the job if I could give them the image sizes that they need. You guys have helped a ton!

The real answer is it depends on the viewing distance.
Surely if a 3MP Canon D30 can be blown up to 75"x100" @ 240dpi then a newer camera with more pixels can easily go at least that big... |

Don't give it up too quickly.
First of all others who may take the job may not have a pro DSLR (12MP+) or medium format camera so it may be that they won;t get any better anyway.
Secondly, for display images you don't necessarily need the quality of print that you would want for a fine art print. Large prints look great when viewed from 10 or 12 feet away. Photographers have a habit of sticking their nose right into prints to see if they can detect a flaw. That's not the real world.
The question is whether they are after large size, high quality photo prints (and whether they know what they'd have to pay to really get that sort of quality) or whether they want to produce 'posters' or something similar.
