Instant prints are sold in a few small, common formats: credit-card sized prints (about 2 × 3 inches), a small square format (about 2.4 × 2.4 inches), and slightly larger pocket sheets (approximately 2.3–2.4 × 3–3.4 inches).
Some pocket photo paper is sold as peel-and-stick sheets with a removable backing. By contrast, many instant film products are packaged in labeled, easy-to-load cartridges or individually wrapped 10-sheet packs that load into compatible instant cameras or printers.
Most instant prints are advertised with a glossy finish. Pocket photo paper listings often highlight durability features such as smudge-proof, water-resistant, and tear-resistant surfaces, while instant film listings emphasize vivid colors and a glossy look.
Instant film prints typically develop in about 90 seconds. Pocket photo paper using ZINK technology is ready as soon as it finishes printing (product details describe it as immediately shareable, without a specific development time).
