Many hanging displays support standard photo and poster sizes, including 4 x 6, 5 x 7, 8 x 10, 11 x 14, 18 x 24, 22 x 28 and 24 x 36 inches.
Many gallery-style frames include acid-free and beveled mats. Some listings specify an off-white or removable mat board, while others list a single white or off-white mat included.
Many frames are designed to hang either horizontally or vertically. Supported orientations depend on the model; some frames (including certain square or model-specific items) may list only a single orientation—check the product listing for details.
Several listings specify spot or wipe clean as the recommended care method. Many frames ship with protective film on the glazing; product notes will indicate whether to remove that secured plastic sheet for a given frame.
