It's difficult to measure because it's at an angle, but: Height: Approximately 45-50cm Width (at the widest point): Approximately 30-34cm My laptop (30.7cm x 19.7cm) fits, but I think it would be difficult to put anything larger in it. This is a used item. Please understand this before purchasing. #rucksack #backpack #oneshoulder #slingbag #backpack #bag #Nike #Adidas #Puma
