I'm used to design a small icon / graphic art, rather than the big size of A3 paper.

So then When i tried to use A3 as the Paper Size with resolution of 300 dpi. The file size is bigger in Photoshop compared to the file size in CorelDraw.

Is there any calculation that we need to use for achieving a smaller size for designing but the image is safe for later use in printing?

file size : more than kilobytes, it's bigger than megabytes.

  • Your use of bold text here and there makes your text hard to read :) When you say "file size", do you mean the width and height of the image? (It sounds like the size of the file, e.g. kilobytes) Sep 1, 2014 at 12:20
  • zoom @SaturnsEye... does it make a difference by zoom? I never heard of it. Bigger in size MG_,.... Yes, HenrikEkblom.... so how to solve this case?

    There is nothing you can do about this. Corel Draw is a vector program and will save everything in that format making the file sizes very small. The photoshop file is all bitmap based so it will save bigger files.
