How big is a picture 1200 pixels by 1200 pixels?

Answer 1

It will depend on the dpi of the picture. Dpi is the amount of pixels per square inch.

Lets say you have a 4x6 image with a resolution of 200dpi. To find the pixels we multiply the dpi by the inches

4" x 200dpi = 800pixels for your height

6" x 200dpi = 1200pixels for your length

a 1200pixel x 1200pixel would be 6"x6" when converted.

web images have a resolution of 72dpi. High res images can be 300dpi

I hope you find this helpful, it made me sad to see this question unanswered :)
