The two diagrams illustrate the cross section of a frame used to display photos and the front side views of two different picture frames.
Overall, a picture frame consists of six different components and can be of various sizes depending on its material.
The frame itself provides the overall structure to this accessory as it is situated on top and bottom of a photo holder. There is a backing made out of either wood or cardboard with clips attached to its upper and lower sides. The photo goes in front of the backing where a glass protects it. Both the glass protector and the backing are held firmly by the frame.
The frame of an image can be of two materials: either silver or wood. The height of both the frames are fixed at 30 cm; however, the silver frame is 20cm wide and the width of the wooden frame is 1cm less than that. In addition, the visible photograph area of the silver frame is much bigger when compared to the wooden frame.
