Problem with Photoshop CS canvas size??

When I want to make a new project in Photoshop I will click new and then it asks me for the measurments of the page. So say if I enter 10cm for the Width and 30cm for the height it then loads the page and its a completley different measurment than what I put in and also wen i click save now its also not what i put in. How do i resolve this annoying problem?

make sure that your rulers are also set to cm. Also check and make sure you are viewing at 100%. Hope this helps

The image will appear bigger in photoshop when the resolution is higher.

So, check the resolution after entering the measurements, its normally 72 px perinch

Always follow the measurements in your computer instead of what you see on your screen . CTRL+R to view rulers on your new document/ page.

Good Luck!
When you start a new project, these are the settings you'll get:

Width: (set this to 30, make sure ''cm'' is selected in the drop down box)

Height: (set this to 10, make sure ''cm'' is selected in the drop down box)

Resolution: (Set this to 300, make sure ''pixels/inch'' is selected in the drop down box)

Ignore the other settings for now.

I suspect that the resolution was left as 72, which is for images to be viewed on screen, not at 300, which is best for images to be printed.

Finally, once you have your settings, click on the ''save preset . . . '' button (on the left of the ''New'' dialog box). This will save the settings for future use.
