The [postcards](https://www.inmateaid.com/postcards) are 4" x 6" and the photos are printed on the back of the card (up to four total). There is a small border so the pictures will appear to be small if you put four in that space.
The [photos](https://www.inmateaid.com/letters) that come with the letters are 4" x 6" glossy paper printed to the edge of the paper. These are of the higest quality and are much better for important pictures you want your inmate to have.
