HOW TO FIGURE IT OUT FOR YOURSELF
如何使用2.25英寸法则自己测量

Grab a ruler and a pencil. Place the pencil under your chin horizontally. Then place the ruler under your ear,vertically.Theintersection of the pencil and ruler indicates a measurement. If it is less than 2.25 inches, then like Halle Berry and Audrey Hepburn, your face is made for short hair. If that measurement is more than that length, like Kim Kardashian and Sarah Jessica Parker, then long hair will be the most flattering choice.
首先拿出一把尺子和一只铅笔。水平第将铅笔放在下巴下方，然后将尺子垂直放在耳朵下面，铅笔和尺子之间形成的截面显示出一个长度。如果长度小于2.25英寸，像哈莉·贝瑞和奥黛丽·赫本一样，那么你的脸型适合留短发；如果长度大于2.25英寸，像金.卡戴珊和莎拉·杰西卡·帕克，那么长发则更加适合你。

So, the next time you're admiring someone's short crop, or longing after their long hair, just remember The 2.25' Rule... if the distance from the bottom of your ear to your chin is greater than 2.25', you might want to stick with longer haircuts. If that distance is less than 2.25', you have a face suited to short hair, even a super-short pixie cut.
所以，下次当你再羡慕别人的短发或是长发时，只要记住2.25英寸法则就好了。如果耳垂到下巴的长度大于2.25英尺，你适合选择长发，如果这个长度小于2.25英寸，那么你适合短发，甚至超短发。
