Although jackets and coats are both types of outerwear clothing worn for warmth, added coverage, and style, there are a couple of differences between the two.
Jackets are typically shorter than coats and have varying lengths. Some jackets feature cropped styles that hit above the waist. However, most generally stop at the waist or just above or below the hip.
Coats are usually longer than jackets and range from mid-thigh to below the knee. Typically, coats are worn as functional outerwear. Thick and heavy winter coats, for example, are designed to keep your chest and legs warm during cold months. Waterproof rain coats will protect your clothes from getting wet.
