Small: 7x7 inches. This size is perfect for covering half a lemon, a cup, small snacks or a small bowl. I keep a small in my purse- never know when you might need it!
Medium: 10x10 inches. This size is the most popular- can cover most fruits and veggies easily. Great for bowls and covering leftovers on a plate. Also fits perfectly over 8x8 baking dishes. This size is must have!
Large: 10x16 inches. This size is will cover your larger bowls, plates and casserole dishes, as well as everything that your medium couldn't quite cover.
