You need about 150 pixels/inch for quality printing, so divide your image size (in pixels) by 150 to get the dimensions (assuming no cropping or resampling) -- it will probably end up between 16x20 and 20x30 inches.
With careful upsampling you can print bigger. |

How big do you want to go?
I've printed 20X30 prints from my old 6MP D70s that customer's raved about.
Edit - I did shoot RAW, ISO 200 and the lighting was very good.

| Arg, well i have this picture i took for a challenge and i REALLY like it, but its cropped quite a bit its at 1274 width 930 high so that doesn't work out to make a very big picture, aside from trying to recreate this picture but move the camera closer, is there any way i can get more out of this size wise without loseing much quality? |

If you have Photoshop CS or higher or PS Elements 3.0 or higher you can probably resample the image up to 150-200% of the original size without too much degredation; use the Bicubic Smoother option/algorithm in the Image Size dialog. You may need to use some form of sharpening afterwards.
You can also use a program specifically designed for enlarging, like Genuine Fractals, but that's kind of an expensive solution for just one photo; they claim you can upsample to 400-800% of the original size while still producing a useable image. |

| wow, may have to look into that in the future if i find i need it enough, though i probably wont. Its just a picture of my cat that i got quickly from a distance. It looks awsome at 640pix when i scaled it down for the challenge, the original size of that image is 1274 wide 930 high, but my parents want it blown up for over the fireplace, so ill give the trial a run and see how it goes. |

So how big can a 9 mp camera go?

| How about aking a 5x7 print out of the subject and than scanning it using a scanner for the size you are interested in |

When using bicubic smoother, you can get better results by upsampling 10% at a time. This will take many upsamples, but the results are worth it. |

No, sorry, that would only degrade the quality further. You can't put quality or megapixels in after the fact. Gotta have 'em to start with. Even Genuine Fractals is going to lose some quality. |

This method was used with the pre-CS versions of PS, which only had the plain "Bicubic" algorithm. Adobe now recommends one-step upsampling instead. Which method works better may depend on the individual image. |

| I like to use Outback's Photoshop CS Action. It can be downloaded for free. Install it as an action and when you use it, it will ask you how long you want the longest side and what dpi you want (I generally print 300). |
