Pixel-Inch Converter & Aspect Ratio chart

 
To determine the smaller dimension of a panorama, adjust the dpi until the larger inch dimension matches the size you want to print. The smaller dimension will then be viewable below. A dpi less than 100 may mean that your image is not suitable to be printed at the selected size. Images in question may be sent to the email address listed on the Contact Us page. We will reply with the suggested print size that will produce the best print quality. (100 to 300 dpi is our standard print resolution range)
