Throw blankets are smaller than standard blankets for a few reasons. First, they are designed to be used as an extra layer of warmth on top of another blanket or comforter. They are not meant to be the sole source of warmth like a standard blanket. Second, throw blankets are usually made from materials that are thinner and more lightweight than a standard blanket. This makes them easier to carry around and drape over yourself without feeling too bulky or heavy. Third, throw blankets come in a wide variety of colors, patterns and designs, so there is more opportunity for creativity and personalization in their size and shape.
