Hello, the dimensions of the bag are Width: 29 cm, Length: 40 cm, Depth: 15 cm. Although it looks long in the picture, this is because of the rectangular and practical design of the bag. When worn on the back, it fits your body more harmoniously and does not give a very rough appearance. It takes its shape as you put items inside because it is made of flexible polyester fabric, and it looks more compact when empty. Don't worry, it is a very suitable and fashionable bag for daily use. Thank you for your inquiry � �
