Digital Camera Glossary | Frequently Asked Questions | Print Sizes | How Many?

In digital imaging size is important.

This size of your print and the print quality are dependent on the image size. The higher the resolution of the image, the larger the print size.

That being said, there are a number of other factors that will affect the print quality. Besides image size there is compression settings, printer type and even the type of paper that you print on.

Generally for good quality prints you will need 300 ppi (pixels per inch). That means that with a camera that has a resolution of 2.1 megapixels (1800x1200) you can expect to get excellent standard size (4inch by 6 inch) prints (1800/300=6 - 1200/300=4). Some of the new digital printers can push that size and get decent 5x7 prints and acceptable 8x10 prints. From personal experience I can tell you that my first digital camera was a KODAK DC260. With its 1.6 megapixels I regularly printed excellent 8x10's on an EPSON Color Stylus printer. For more on image resolution and print quality you can visit my page on that subject.

See the chart below for a quick file size to print size reference.
