Science Confirms That Women's Pockets Suck For Smartphones (theverge.com)
It's a well-documented, often criticized phenomenon that women's pockets are too small to fit a smartphone, but "there's been very little data to back up a wealth of anecdotal evidence," writes Megan Farokhmanesh via The Verge. Now, The Pudding has used scientific findings to fill this absence. From the report: According to The Pudding's findings, pockets in women's jeans are, on average, 48 percent shorter and 6.5 percent narrower than those of men's. To put this into a perspective we all care about, the site says that only 40 percent of women's front pockets can completely fit a iPhone X. The number only goes down for the Samsung Galaxy or Google Pixel (20 percent and 5 percent, respectively, though the report doesn't specify which model) of the flagships). As for men's pockets? The Pudding marks a 100 percent success rate for the iPhone X, 95 percent for the Samsung Galaxy, and 85 percent for the Google Pixel. "If you're thinking 'But men are bigger than women,' then sure, on average that's true," the site adds. "But here we measured 80 pairs of jeans that all boasted a 32 inch waistband, meaning that these jeans were all made to fit the same size person."
The iPhone X is just a gargantuan bastardized "bigger is better" mutation of Steve Job's perfect one handed smart phone design.
Plus you're still "holding it wrong". ;-)
The reason why there are men's and women's pants is due to having different cuts. Men and women on average have different proportions and as such, having the same cut would require it to be rather baggy or rather uncomfortable.
Men tend to have longer waists and shorter legs than a similar sized woman who tends to have a shorter waist and longer legs. Most likely a hold over from back in olden times when women had to be able to run and walk at similar speeds to what men were managing.
But ignoring that, women tend to have proportionally wider hips than a man with similar leg length and men tend to need some sort of allowance for their Balzac otherwise it gets rather painful. Which is something that women don't need to worry about, there isn't anything down there to sit on or squash.
That being said, by both comfort and utility wearing the same pants wouldn't be particularly practical as they'd have to use more material and not be particularly comfortable for men or women.
