In a new challenge circulating on the Web, women are comparing the size of their iPhones to the width of their knees.
The photos, which seem to be getting a lot of attention on social media, are strikingly similar to the A4 Waist Challenge — only for that, women were instead using a sheet of paper to reveal the size of their waists.

Photos were recently posted on Weibo, a Chinese micro-blogging site, and shortly thereafter the "iPhone 6 knees" challenge spread like wildfire. (Weibo is also believed to have been the platform where the A4 Waist Challenge started.)

Just like its predecessor, this trend takes a commonplace object — at least in tech-heavy parts of the world — as a standard for comparison. It's a matter of being able to say that your legs are skinny, by the silliest of standards — if your knees are no larger than your iPhone.

So, let's change the game a little, shall we? To start, stop comparing body parts to objects.
