Whether the iPhone 13 Pro Max is too big for a pocket largely depends on personal preference and the size of the pockets. With a height of 6.33 inches (160.8 mm) and width of 3.07 inches (78.1 mm), it is one of the larger smartphones on the market. Some people might find it too large for comfortable pocketing, especially in tighter clothing, while others might not have an issue. It’s best to consider your comfort with larger devices before purchasing.
