Not that kind of size, you pervert. <3
I would like you to take out a ruler.
1) Measure the length of your hand from your wrist to the very tip of your middle finger.
2) Hold your hand out flat, palm up, with your fingers together, but without pressing your fingers too tightly together. Measure the width of your hand, from your first knuckle of your thumb (the knuckle farthest from the tip of the finger) to the other side of your hand directly from that knuckle.
EDIT: I didn't explain 2) very good. Basically, hold them like in this picture here.

Record the measurements in both inches and cm. Here is a converter.
Me:
1) 6 1/4 inches (15.88 cm)
2) 3 1/2 inches (8.89 cm)
I have very small hands, even for someone who's 16 and only 5'0", and I want to know the hand sizes of everyone else.
