The size is perfect for me. It fits more than what it looks like! It's a great bag for my commute. It fits my Macbook pro 13 inches. The pockets on the sides are convenient to carry an umbrella and a water bottle. I would like a pocket inside but at least there's one on the front. Only thing I don't like is that I bought black and looks dirty all the time. The material picks up every single speck of dust!
