We offer four different poster frame sizes. All frames have a standard depth of 0.75" (2cm) thickness and come with a mounting kit, so they are ready to be hung. Frame molding size varies from 1"-1.5" depending on your portrait size. Our framed poster sizes are: 8” x 12” (21 x 30 cm) 12” x 18” (30 x 45 cm) 18” x 24” (45 x 60 cm) The frames come pre-packed with corners and film and then packed in a box with strong edges to protect the frames. I-beams are used in addition, to give the package additional sturdiness and for multi-item orders (max 3 frames in one package).
