Picture frames are basically four pieces of wood molding or metal strips joined together. The frame pieces come in a range of lengths and widths and a wide variety of decorative styles. Frames are usually chosen to complement the wall they will be hung on. The background color of the wall may dictate the frame material and finish—a gold frame looks wonderful on a wall that is a deep, warm color.

Framer's molding is designed and used for making wood picture frames. The wood may be maple, walnut, pine, oak, or mahogany; and the finish may be plain, sealed, stained, or painted. Some frames combine woods and finishes; others may be gilded in gold or silver. Fake effects are sometimes painted on the frame, or a frame may have a lacquer finish.

Metal picture frames are another option. Aluminum, brass, and steel are used to fashion these frames. They come in a variety of colors.

Antique frames are sometimes acquired from antique shops or house and yard sales. These frames are often well worth restoring. Old glass can be replaced with non-reflective glass, the frame can be refinished, and a new mat and painting can be inserted.
