Vistaprint does NOT offer TRUE 4x6 or 5x7 invitation sizes

I am not personally familiar with the flat card printing service on Vistaprint but it has been brought to my attention by previous customers that they do not offer TRUE 5x7 size invitations.  I went ahead and took a look at their website and there is a problem.  These are the specs they indicate for "their" 5x7 invitations:

Full Bleed Size

7.28" x 4.72"
185 x 120 mm
2185 x 1417 pixels

Document Trim Size

7.17" x 4.61"182 x 117 mm
2150 x 1382 pixels

Now, ALL of my designs are industry standard "full bleed size".  When I say industry standard it is because my designs are TRUE either 5x7 or 4x6 size.  My bleed size which is what is used in the printing industry is 1/4 inch extra size all around so for a 5x7 invitation - the file actually measures 5.25" x 7.25" so that when they are professionally printed, you get a TRUE 5x7 invitation.  Printing industry automatic cropping is 1/4 inch all around.

So MY high resolution 5x7 printable files DO measure 2175 x 1575 pixels (which equals 5.25 x 7.25) and MY high resolution 4x6 printable files DO measure 1875 x 1275 pixels (which equals 4.25 x 6.25).

Vistaprint, however has a totally different "bleed size" and  their final document or invitation size (after cropping) is NOT a true 5x7 invitation but rather a 7.17 x 4.61 invitation (see above where it reads "Document Trim Size" which I got from their website specs.  This means your final printed product will only measure 7.17 x 4.6 (again, not a true 5x7).

I only offer true 4x6 or 5x7 invitations.  Those sizes/specs Vistaprint uses are not industry standard and must only be for their own proprietary equipment.

As a matter of fact, I have checked and they do NOT offer true 4x6 either - here are their specs for the closest size to 4x6 - so the final invitation size will measure 5.47 x 4.21:

Full Bleed Size

5.59" x 4.33"
142 x 110 mm
1677 x 1300 pixels

Document Trim Size

5.47" x 4.21"139 x 107 mm
1642 x 1264 pixels

I cannot change the dimensions of my designs - they will end up being distorted in the end if any changes are done to the file size and it would literally require me to begin working on a new file size from scratch - plus I would not be able to guarantee results with those specs.

I would encourage you to run a Google search for "digital printing service 5x7 invitations" or "digital printing service 4x6 invitations" to compare with other printing companies.  I know my customers have never run into a problem like this before except with Vistaprint.
