•  A picture frame is a border or case used to   enclose and display a   picture, painting, or photograph

There are various types of picture frames, including standard, gallery, floating, deep-set, and modern wall tile frames. 

Materials:

Picture frames can be made of wood, metal, or other materials. 

Examples:

Standard frames: Simple, classic designs, often made from wood and glass.

 

Gallery frames: Rectangular with rounded corners and no ornamentation.

 

Floating frames: Use clear glass or acrylic instead of a mat, creating an impression of the photo floating on the wall.

Deep-set frames: Use a thicker mat and deep frame to draw the eye inward toward the image.

 

Modern wall tile frames: Nail-free and glassless, suitable for renters.
