What's the difference between the Dell Inspiron 13, 14, and 15 laptop?

I posted a question about buying a Dell Inspiron 15 laptop, but, I'm starting to get confused with the models. Can you explain the different elements in these three laptops and how they differ from one another. Thanks so much in advance!!!

You can customize your computer to meet your needs and price on their website. Their website is very helpful and easy to use. It explains what things are and keeps a running tab on the price. It is better to call them to place the actual order as it cuts off a few days in the wait to receive it. You can customize it online and the phone rep can pull your cart if you have an account. Then they can check into other promotions that apply to your order.What's the difference between the Dell Inspiron 13, 14, and 15 laptop?
