Sometimes your left ear might look pointier than your right ear. A good observation would show you that this is a common feature in most humans. 

Unfortunately, many people lose self-confidence or feel uncomfortable the moment they discover both sides of their faces aren’t the same. Some might even give their own theory as to why both sides of their faces aren’t the same. 

Now, let’s answer this pressing question.  

Why is one side of my face bigger than the other? 

A major reason for this is a factor known as Facial Asymmetry.

The word asymmetry means not symmetrical or not identical. So facial symmetry is a condition in which both sides of a face don’t align in the same way. 

There is nothing to be afraid of, as this is common and normal for most or all humans. It only becomes a problem when one part of your face becomes distorted, which can happen for various reasons.

However, in some cases, it can be extremely noticeable, and in such cases, the affected person can take personal or medical approaches to correct this issue.

 For most recorded cases, facial asymmetry can be corrected and is often temporary. In the case of severe injury, A doctor can prescribe implants.

These are all a result of aging body cells in the entire body. It would also affect the facial appearance to a wider degree than in the youth. 


Stroke is also a major medical cause. It is a medical condition in which one part of the human body, either left or right, feels numb or tired and cannot move. It can distort the face and cause difficulty in speaking.

It usually occurs during childbirth, or when one enjoys keeping his or her head in a particular position for a long period. It would be interesting to note that this happens to three in every hundred babies born. 


Genetics is another reason why facial asymmetry occurs. It goes a long way to depict what to expect. So, if someone is born into a family with facial asymmetry as a genetic trait, it becomes natural to expect the same. 

Accidents and injuries:

Accidents can leave a person’s face asymmetrical. It could be a fire accident, a serious wound or injury.

  • Draw a neat oval shape around the face. Ensure the lines of the oval shape are not too big or small but fit closely to the edges of the face before you as much as possible. 
  • Divide the oval into two vertically from top to bottom. 
  • Draw a horizontal line slightly above the tip of the leap for one side of the face, then draw the same for the eyebrows and the tip of your nose as well.
