Yeah, except that she's got an iPhone 12 (check the pics in the thread, I think remi even mentioned it on twitter when she got it as a new phone) which is 14.67cm in height, thus making her actual numbers more akin to be somewhere around ~17.5cm (~6.9") in lenght and ~4.3cm (~1.7") in diameter.
I dunno why would some1 consider that small, I think most people would be pretty happy with such dimensions.
