What is resolution?
Image size/resolution describes the detail/fineness an image holds. The term applies equally to digital images, film images, and other types of images. Higher resolution means more image detail. Resolution is measured in pixels per inch (ppi) or dots per inch (dpi).
DPI vs. PPI - what's the difference?
This is a confusing concept that is widely misunderstood.
Technically, DPI and PPI are two totally different things. DPI is "dots per inch" and is used for print material. PPI is "pixels per inch" and refers to how images are displayed on computer monitors. But in the digital scrapbooking world, the two terms are used interchangeably.
Most digi scrap elements and kits that you download are 300dpi. Because of this, creating your layouts at 300dpi is optimal - and more convenient.
The Basics
• The more ppi = the higher the resolution = the higher the image quality.
• Higher dpi = larger file size.
• The web and email standard for images is 72dpi. The printing standard for images is either 200 or 300dpi.
