This isn’t super tech-related, but this website gives a nice visualization of how men’s pockets are bigger than women’s pockets. There’s also a section that lets you find jeans that can fit smartphones like the iPhone X, Samsung Galaxy, and Google Pixel.
Only 40 percent of women’s front pockets can completely fit one of the three leading smartphone brands. Less than half of women’s front pockets can fit a wallet specifically designed to fit in front pockets. And you can’t even cram an average woman’s hand beyond the knuckles into the majority of women’s front pockets.
