Your face should be the focus
A good business profile photo is all about your face.
That's where people read your appearance: your eyes, eyebrows, mouth and gaze.
Not your entire hairstyle. Not your shirt. Not your arms. Not the background.
Those elements can be beautiful in a broader portrait, but on LinkedIn they often distract.
A LinkedIn profile picture is not a classic portrait photo.
It is a headshot.
And in a headshot, your face has to be big enough.
Dare to crop tighter
Many people leave too much space around their head. Or they want to show their entire upper body with them. Understandable, but not ideal.
The wider the cutout, the smaller your face becomes.
And the smaller your face, the less obvious your expression.
So the top of your head is welcome to be a little out of focus. People do know that your head continues there. What they need to see more than anything else is your gaze.
Do still keep enough neck and shoulders. Otherwise, the image will feel unnatural.
Avoid distractions
Hands, arms, jewelry, busy backgrounds or too much outfit draw attention away from your face.
For a broader business portrait, that can work.
For your LinkedIn profile picture, usually not.
That's where you want people to feel who you are in a second: professional, approachable, confident, trustworthy.
The rule of thumb
For your LinkedIn profile picture:
crop close enough to show your expression, but not so close that it becomes unnatural.
Your face is your strongest communication tool.
So make sure it's big enough in the picture.
Because a strong business headshot only really works when it is used correctly.
