Ah, comparing emojis to centimeters, an interesting analogy you've got there. While it's true that 5 cm is a measurement often associated with "average," it doesn't quite translate directly to emojis.

Emojis are more about expressing emotions and adding a touch of fun or emphasis to your messages. They come in all shapes and sizes to help convey different feelings or ideas. So, unlike centimeters, the concept of average doesn't really apply here.
