Get Your Headshot Cropped Right for LinkedIn, Zoom, and More

Why One Photo Size Never Fits All

Your headshot is not a one-way door. It’s a revolving one, appearing in different frames for different people. Think about the last time you saw a colleague’s face. Was it a tiny circle on a Zoom call? A rectangular banner in an email signature? A larger square on a company website? Each platform has its own window, and if your photo doesn’t fit, you get cut off.

I once shot a lawyer who insisted on using his website banner crop for everything. On LinkedIn, the top of his head was sheared off. In his email, only his left ear and shoulder showed. He looked like he was perpetually dodging the frame. We fixed it by exporting three specific crops from our session. His face finally looked intentional everywhere.

The core problem is aspect ratio. A square (1:1) photo behaves differently than a rectangle (4:5 or 16:9). Upload the wrong shape, and the platform’s automatic cropping tool takes over. It’s a robot guessing where your face is, and it usually guesses wrong, slicing through your chin or forehead. You wouldn’t let a stranger choose your outfit; don’t let an algorithm choose your crop.

The Exact LinkedIn Profile Picture Specs

For LinkedIn, the magic number is 400 x 400 pixels. That’s the official size. But here’s the secret they don’t tell you: upload a larger, rectangular image, and let LinkedIn do the final square crop. Why? Control.

Upload a photo that is at least 1584 pixels wide by 396 pixels high. This is their recommended banner size, but the principle works for your profile picture too. When you upload a larger, high-quality rectangle, LinkedIn gives you a zoomable cropping interface. You can slide the image around to ensure your eyes are dead center and your shoulders are framed perfectly. If you upload a pre-cropped 400x400 square, you get no adjustment. Zero. One misaligned shot and you’re stuck with it.

What is the single most important thing to check after you upload? The thumbnail. LinkedIn shrinks your photo to a tiny circle in comments, messages, and search results. Pull up your profile and look at that minuscule version. Can you still see the warmth in your expression? If your face is a dark smudge, go back and brighten the original. That tiny circle is your first impression 90% of the time.

Sizes for Zoom, Slack, and Email Signatures

These are the daily drivers. The specs are looser, but the rules are stricter.

Zoom and Slack display your image in a small circle. They both automatically crop a square from the center of whatever you upload. So, you must feed them a square. I tell clients to use a 1000 x 1000 pixel version of their LinkedIn crop, but zoomed in slightly tighter. You have less real estate, so fill it with your face and a genuine smile. Test it. Open Zoom settings, upload your square, and then join a test meeting. Does your head look centered, or are you floating in space?

Email signatures are the wild west. They’re often rectangular. A safe, versatile size is 300 pixels wide by 400 pixels high (a 3:4 ratio). This fits most email clients without distortion. Keep the file size small—under 100KB—so it loads instantly. Your goal here is clarity, not art. People need to recognize you at the size of a postage stamp.

• Zoom/Slack: Upload a pre-cropped square, 1000x1000 px.
• Email Signature: Use a small rectangle, 300x400 px, under 100KB.
• Company Website "Team" Page: Ask your web manager for the exact required dimensions. Never guess.

The Common Mistake: Uploading a Square Crop

This is the biggest technical error I see. People get their beautiful final headshot, crop it to a perfect square for LinkedIn, and use that same file everywhere. It’s a disaster. That square, when forced into a circle for Zoom, often loses the tops of the ears or the very bottom of the chin. It looks amateurish.

Remember the lawyer? His original square crop, when uploaded to his firm’s rectangular website template, created two giant grey bars on either side of his head. He looked like he was in prison. The fix was simple: we gave the web manager a 800x1000 pixel version of the same shot. Suddenly, he looked professional and engaged.

You need a master file. This is your high-resolution, uncropped original. From that master, you create your children: the LinkedIn-ready rectangle, the Zoom square, the email signature crop. One parent, three kids. Never use one kid for all the jobs.

How Portraze Delivers the Perfect File

So how do you get this right without becoming a photo-editing expert? You plan for it before the shutter even clicks. During a session, I’m already thinking about these crops. I frame the shot knowing that 20% of the left side will be cut off for your Zoom circle, and that the top of the frame will be your LinkedIn banner.

I watched a client last week, a software engineer, nervously adjust his glasses between takes. He kept his hands near his face. Knowing I needed clean space around him for cropping, I guided him to drop his hands to his sides for a few key frames. Those became his master shots—versatile, with “crop-able” space. The final delivery wasn’t one photo. It was a folder: “LinkedIn_Rectangle.jpg”, “Zoom_Square.jpg”, “Email_Signature.jpg”. Each one was purpose-built.

The final step is the technical export. This is where pixel dimensions and file compression matter. A file for the web should be a JPEG, saved at 80-90% quality to balance clarity and small size. The print file is a different beast entirely. When you get your photos, you shouldn’t have to think about any of this. You should just have the right file for the right job, ready to go.

Your headshot is a tool. A good tool fits the hand of the person using it. Make sure yours fits the frame it’s meant for.
