Image Size Calculator/Convertor

Post by univurshul » 14 Nov 2010, 12:45

I found a simple to use online tool for Pixel-to-Inches & vice versa for various applications: http://tiporama.com/tools/pixels_inches.html

I decided to pursue the idea of sizing to better grasp what dimensions I'm looking to produce on specified displays.

Say I have 5 different devices to read ebooks: 27" cinema display, 1080i LED projector, iPad, iPhone, MacBook Pro 15". This conversion tool has helped guide me on the media size by simply plugging in the data.

Too often, DPI & ppi is related to reproducing the media on a printer....what's a printer? :lol:

.what's a printer? :lol:
LOL, I know! And what confusion all the DPI talk causes, when our output devices (like projectors) are continuously variable... Thanks for the tip.
