Am I going crazy here?! (VistaPrint help!!) I designed my own invitations so that I could print them on VistaPrint. I wanted them to be double sided on a 5x7" invitation.

So I designed both the front and the back in Photoshop. I went to upload my designs and the front was perfect. The back...not so much.

The image I designed has a border around it to fit very close to the 5x7" frame. When I uploaded it, the design is too short!! So it looks really silly.

Am I missing something here? Are the VistaPrint front and backs not the same size? I'm really frustrated because I've already completely redesigned the back to fit a 5x7", and now it looks like I'll need to do it again and I'm not even sure what size I'm supposed to be working in!!
