Standard mailer templates are 6" x 11", but the uploaded file must be 6.25" x 11.25" at 300 DPI to accommodate the print bleed (trim area). Make sure to keep all critical content within the safe zone, at least 0.125" from the edges. And on the back side, leave a 2.375" x 4.375" postage area - any content in this area will be covered by the postage stamp.
Uploaded files must be in JPG or PNG format and < 5MB.
Please follow the template below when creating custom designs.
