D90 Maximum print size

What is the maximum size of a photo that can be printed in high quality with an uncropped D90 image?

I noticed that Zenfolio warns of resolution and print size on some of my images that have been cropped and are of a lower resolution.

•Nikon D90 12.2Mp 300 DPI (Highest Quality) – 14.3″ x 9.5″
•Nikon D90 12.2Mp 240 DPI (Good Quality) – 17.9″ x 11.9″
•Nikon D90 12.2Mp 200 DPI (Average Quality) – 21.4″ x 14.2″
•Nikon D90 12.2Mp 150 DPI (Poor Quality) – 28.6″ x 19″

Thank you! Was exactly what I needed.

Though, if you need a really huge prints, you can get acceptable results by raising the resolution or a "print size" with programs such as PhotoZoom pro (S Spline Max mode)...

To give some perspective, Mike, 300 ppi is usually described as a "magazine quality photo" and looks sharp even when you look at it up close. When I was first getting into printing and framing photos, I had a 16x20 printed that came out to about 160 ppi. ShootRaw's chart describes that as poor quality, and I would agree to a point. If I held the photo about 8" away from my face, I can see individual pixels. But no one looks at a 16x20 hanging on the wall that way. You tend to step back a few feet to take in the whole photo, and from that distance it looks great. Now if you print a 3x5 at 160 ppi, people will notice just because you tend to look at something that size a lot closer. Just some things to think about.

Oh, and if you want to go bigger, consider canvas. I had a coupon for one of the places that prints on canvas (I can't remember which one) and decided to try something out and printed a 1MP image at 20x30. I don't remember the exact count, but I believe it came out to around 40ppi. The texture of the canvas tends to hide the low quality of the image. If I did it again, I don't think I would go quite as extreme, but it's something to consider.

Have printed many 16 x 20" from an old 8mp Sony Cybershot that looked good from a few feet away.

I was just setting the print order sizes in Zenfolio and wanted to eliminate the really large prints from the order choices.

I printd many @ 16x20, and 12x18.

I would say 12x18 as a max. Have some 16x20's printed and find out for sure!
