Does it come with a mat?

The frame is described as holding a 13 x 19 inch print directly, with a glass insert. No mat is listed among the included components, so plan on buying one separately if you want a matted look.

Can it stand on a table or does it only hang?

It does both. The easel backing lets it stand on a flat surface, and it can also be wall mounted in either vertical or horizontal orientation.

Is the front glass or plastic?

The window is glass, and a glass insert is included. That gives clearer viewing than acrylic but makes the frame heavier and more prone to breaking if dropped.

What size photo fits?

It holds a 13 x 19 inch photo, document or flat art. The frame itself measures about 52.1 cm tall by 36.8 cm wide and 1.91 cm deep.

How wide is the frame border?

The border is 3/4 inch wide all around, and the frame is 3/4 inch deep. That slim profile keeps attention on the print.

Is mounting hardware included?

The listing names the glass window and glass insert as included components. It does not list hanging hardware, so check the box contents or plan to supply your own hooks and nails.
