When choosing a KitchenAid mixer, there are several factors to consider, including size, type, and color. The size of the mixer bowl can range from 3.5 to 8 quarts, with smaller mixers offering 2 to 3.5 quarts of capacity and larger mixers offering 5 to 8 quarts. The most popular size is around 4 to 5 quarts, which is a great size for everyday recipes and meals. If you plan to use the mixer once in a while or have less counter space, a 3.5-quart mixer might be a good choice. If you plan to make large quantities of food, a 5- to 6-quart mixer might be a better option. The type of mixer can be either tilt-head or bowl-lift, with the main difference being the way the bowl is attached and accessed. Tilt-head models allow the mixers head to pull back, and the bowl is fixed to the base of the stand mixer, while bowl-lift models have a lever that raises and lowers the bowl. KitchenAid offers over 40 stand mixer colors and a variety of bowl options to choose from.
