I am using Photoshop CC. My problem is occurs when I create a new file. If I make it with 15cm width and 10cm height (i.e A6 size), when I view it in 100% (i.e print size) the result on my screen is smaller than the paper I'm using. When I compare my school ruler against the Photoshop ruler, units on the Photoshop ruler shows appear to be smaller.

I have not printed it yet, only made it in Photoshop, but when I choose to print it ( Ctrl + P ) it looks like it should be the right size.

Any idea?


Calculate your screen's DPI here: http://dpi.lv/

Enter the results in Photoshop Settings/Preferences under Units & Rulers > Screen Resolution.

  • Thank you guys, it actually work. When i choose "print size" option it fit to my paper. But the zoom size is 33,33%. When i zoom to 100%, it larger than my screen. What is that mean? – SevenT Mar 17 '15 at 4:03
  • You should do some reading on DPI. vsellis.com/… This should be expected. Your document's DPI appears to be 3 times the screen DPI, and so Photoshop does the math and presents in what it thinks are physical units on screen. – Brendonwbrown Mar 18 '15 at 9:15

100% depends on your screen, thats why it is impossible to adjust it to all screens. More about it here: Life size image in Photoshop
