What is the difference between a heated throw and a full-size electric blanket?

Heated throws in this roundup are typically 50"x60" and designed for draping over a couch or lap, while the queen and king electric blankets (84"x90" and up) are sized to cover a full bed. Throws tend to be cheaper and heat faster over a smaller area; bed-size blankets cost more and, in larger sizes, sometimes offer dual-zone or longer timers.
