These Greeting Card invitations measure 5" x 7" when folded and fit into our 5 1/4" x 7 1/4" envelopes. Envelopes sold separately. Greeting Cards come flat and measure 7" x 10" before folding. More like the type of card you would buy in a store. May require creating your own software layout. Made from a 10.5 mil (230 gsm) inkjet glossy cardstock. Please note: Our Inkjet Paper is not compatible with Kodak Photo Printers.
