Understanding Resolution
Resolution is the fineness of detail in a given image. It is measured in pixels per inch (ppi), often referred to as dots per inch (dpi). The more pixels per inch, the higher the resolution and quality of an image.
All quality digital scrapbooking files are created at 300 dpi, and you should create your layouts at this resolution.
The higher the resolution, the larger the file size. It is standard for images viewed on the web or via e-mail to be saved at 72 dpi. For printing, however, images should be saved at 300 dpi or they will appear pixilated.
Fomula
Inches x Resolution = Pixels
example: 12" x 300ppi = 3600 pixels
Common Scrapbook sizes (300ppi):

Formula |
| 12" x 12" | 3600 x 3600 | 12 x 300=3600 |
| 8" x 8" | 2400 x 2400 | 8 x 300=2400 |
| 8 1/2" x 11" | 2550 x3300 | 8.5 x 300 = 2550 |
Rules to remember
- Text should be 400dpi at the final size in the layout.
- Images should be 300dpi at the final size in the layout.
- Resolution and size (dimensions) are inversely proportional to each other. So, if you enlarge an image, you lower its resolution. If you reduce an image, you increase its resolution.
- How an image is originally acquired will determine its resolution, and thus the size it can print at for clear and crisp printing.
- Low resolution images print with jagged edges and appear fuzzy
