Suggested number of megapixels for high quality prints

Below are the suggested numbers of megapixels to use for common print sizes.
If you crop your images increase the minimum suggested megapixels.
Today it is difficult to find a digital camera with less than 5 megapixels;
Some cameras will automatically reduce the size of the image when you switch between certain modes such as a high ISO

 Print Size     Megapixel Camera           Pixel Size

4 x 6″              2 megapixels                     1600 x 1200
5 x 7″              3 megapixels                     2048 x 1536
8 x1 0″            5 megapixels                     2560 x 1920
11 x 14″          6 megapixels                     2816 x 2112
16 x 20″ +      8+ megapixels                   3264 x 2468

Print quality depends on a number of factors, such as the visual quality of the original image, Printer type, ink, and the paper used.
If you plan on doing your own printing, use a photo printer and high quality photo paper for the best results.
