Sizing Images

I'm hoping someone can help me with a problem I've been having regarding sizing images with Photoshop for a long time. It seems like it should be extremely simple but I just cannot figure this out. For example, I want to make some ACEOs, which are supposed to be 2.5 x 3.5 inches and I want them to print at this size.

So I have left the resolution at the standard 72 pixels/inch so that it will print at 100%. But when I enter the values 2.5 x 3.5 for width and height in inches into their respective boxes I get something that is actually much smaller. I tried measuring it with a ruler on my monitor and it actually measures roughly 1.7 x 2.7 inches. This happens with all values. No matter what numbers I enter, the result is smaller than it should be. Why does this happen?

After much messing around and holding up a standrad playing card (which measures 2.5 x 3.5 inches) to my monitor it seems that in order for the correct print size to appear at 72 pixels/inch resolution on the monitor the values for width and height need to be set at 281 x 395 pixels or 3.903 x 5.486 inches. This does not make any sense to me. While I can get by with just using these values for my current project, I would really like to solve this problem. I would like to know why Photoshop behaves this way and how I can get the printing size I want with varying resolutions. I want to be able to type a given value into its box and have the image appear at that size.

Is there a simple math equation to solve this problem? Do I just need to change the resolution? What is going on? This is driving me crazy.

Please help!
