I have two images of similar sizes, but when I turn on the ruler in photoshop, the ruler length in the two images differ. You will find the snapshot of the images with rulers in this link
(http://www.stanford.edu/~shyun/beethovens.html).

The two images are shown with a zoom of 100%. Their sizes are 200×252 (WxH left) and 175×254 (right) pixels. The rulers are all in centimeters. If I print them out, they print out as the rulers say. Does anyone know why this happens?

Thank you in advance,
Sang-Ho

I can’t see your images as they’re still on your hardrive or somewhere. Do both images have the same DPI? (Dots per inch)

Sorry about that. I put the file in the server. Could you check it again? Where can I check the DPI?

Of course. They are at different resolutions.

"Resolution" is a term that indicates how big a pixel is. Say you have an image that is 300 pixels wide and 300 pixels high. If it is 300 pixels per inch, it will print out one inch by one inch. If it is 150 pixels per inch, it will print out two inches by two inches. If it is 100 pixels per inch, it will print out 3 inches by 3 inches.

Hold down ALT and left click on the bar at the bottom of the image that normally says "Doc:" follwed by the file sizes. To make both images the same DPI, use the Cropping Tool, but take out the height and width information and just fill in the desired DPI value before doing the crop.

Or, better yet, just use the Image Size command and turn off "resample image."
