I am designing a postcard and the size of my design is 177x122mm, which I obviously saved as a PSD right awa. Here comes the tricky part. When I send this file to another designer and they open it on their computer, in another photoshop, the size is signifiantly different?
I even added grid markings to show me where my bleed was and when they adjust check the size of the canvas on their end, it shows that "my" PSD is completely off? I believe the size they see is something like 150x119mm. I don't exactly know for sure but it's more than just a few digits off the 177x122mm size we're supposed to be working on.
I gave the file in a USB. I really can't think of why it does this but you guys know better, so please help?
