Photoshop Print Size

Have ever noticed that when you click on the Print Size button when
you have the Zoom tool selected that if you measure the screen the
dimensions are wrong?
Well I find this irritating sometimes. It would be nice to get this
correct. Recently on Ben Willmore's site I found out to put right
this Photoshop error. See the related part of his site on
http://www.digitalmastery.com/content/blogcategory/28/70/

First understand that Photoshop assumes that your monitor screen has a
resolution of 72ppi. Well this was the case years ago but now screens
are almost never like this. I found mine to be 91.64ppi for instance.

So how do we correct this?
1. Start by making a new file from File > New. Set the Width and
Height to say 7 inches each and the resolution to 72ppi. Other
settings do not matter. Click OK.

2. Now go to View > Actual Pixels.

3. Now hold up a ruler across the width of the screen and check what
it measures. Say 6.2 inches i.e. wrong.

4. Adjust the percentage setting shown in the lower left so that the
ruler reads correctly. To adjust the percentage just click on it and
type in a new number. Press Shift + Return or Enter. This allows the
percentage to stay highlighted to enable you to change it quickly and
easily.

5. Once you have done this use the percentage and multiply by 72. When
I did this on my screen I got 127%. When multiplied by 72 I got the
answer of 91.64 [i.e. 1.27x72].

6. Now so that all our photos show correctly open up the Units and
Rulers found under Edit > Preferences > Units and Rulers.

7. Set the Screen Resolution to the calculated number [91.64 for me]
and click OK.

8. Now measure the 7 inch square. Is it right? It is possible it
could still be wrong by a large amount. Now try select the Zoom Tool
and from the Options bar click on the Print Size button. Does this
make it correct? It should be right now. Any slight error could be
because of the difficulty of measuring with a ruler on a curved screen
and the thickness of the glass. But it will be much better than before.

9. There is a point to note that Photoshop has another error in that
the View > Print Size gives a different size to the Print Size button
for the Zoom Tool. This has been corrected in CS3 more or less. But
in general the Zoom Tool Print Size is the one to use for most
versions of Photoshop.

This image can be seen via the Gallery page and it is quite amazing. When you get there you will find that to see the page is pretty obvious. You can zoom in to an incredible degree.
Can you find the green bottle?
