A common question people have when buying picture frames is whether or not to use glass or acrylic for the glazing. Most custom frame shops will use glass unless the frame is over 32x40 inches. For large frames they will strongly consider using acrylic because it is much lighter. Most of the mail order picture frame companies will only ship acrylic. Picture Frame Destination, Inc. will ship glass up to 20x24 inches. Many ready-made frames shipped via mail order are glass and you have to be prepared for breakage. In general it is better to buy glass locally since the shipping cost is high. We have information here on our website that lists many of the pros and cons of glass vs acrylic.
