AI Headshot Sizes: Pick the Right One for LinkedIn, Resumes, and More

The Four Sizes You'll Receive from Portraze

You just got your new headshots back. Don't just download one file and call it a day. You'll get four distinct versions, each with a job to do. Think of them as tools: a sledgehammer, a regular hammer, a chisel, and a precision file. Using the wrong one makes the job messy. The package includes a high-resolution master file (your sledgehammer), a standard LinkedIn crop, a perfect square for social media avatars, and a tiny but clear thumbnail for small comment sections. I've seen clients panic when their beautiful photo looks pixelated on a company leadership page; 99% of the time, they used the small avatar file instead of the high-res one. Grab all four.

Where to Use Your High-Resolution Master File

This is your 6000x4000 pixel powerhouse, the digital negative. Its purpose is professional printing and future-proofing. Use it for the "About Us" page on your company website, the speaker bio for a conference brochure, or the professional biography sheet your PR team sends to journalists. I had a client land a feature in a trade magazine; they asked for a headshot, and she sent the LinkedIn crop. The designer emailed back, frustrated—the image was too small and low-resolution for print. She had to scramble to find the master file. Save it in a folder labeled "Professional Assets" on your computer. You might not need it for a year, but when you do, you'll be glad it's there.

The Standard Crop for LinkedIn and Company Sites

This is your workhorse. It's typically cropped closer than the master file, about from the mid-chest up, and saved at a web-optimized size around 1500 pixels wide. Upload this exact file to your LinkedIn profile photo spot. Use it on your company's internal directory, professional membership sites like Lattice or Greenhouse, and networking platforms like Xing. The cropping is intentional: on LinkedIn, your face appears inside a small circle. This crop ensures your eyes and smile are the clear focal point, not your shoulders or the background. A good test is to upload it and view your profile on your phone. Can you recognize your own expression from five feet away? If not, the crop is wrong.

Avoid This Common Profile Picture Mistake

The biggest error I see is inconsistency. You have a sharp, professional headshot on LinkedIn but use a cropped group photo from a wedding on your company's Slack. Or you use the square avatar file on your email signature, which then gets stretched and distorted in the company directory. This scatters your professional brand. Someone finds you on Twitter, then looks you up on LinkedIn, and they aren't sure it's the same person. Your profile picture is your visual handshake; make it the same firm, confident gesture everywhere. Pick one of the four files—likely the LinkedIn crop or the square avatar—and use it across the board. Uniformity builds recognition.

How to Update Every Profile in 15 Minutes

Set a timer. Open four browser tabs. In the first, go to LinkedIn, click "Edit public profile & URL," and update your photo with the standard crop file. Second tab: your company's internal HR portal (like Workday or BambooHR). Third tab: your primary email client (like Gmail) to update your signature photo. Fourth tab: an industry-specific network you use, like GitHub or Behance. Now, systematically upload the correct file to each. Use the square avatar for places that display a tiny circle icon. For everything else, use the LinkedIn crop. This 15-minute blitz ensures you present a unified front before your next coffee meeting. Keep the files on your desktop so you can drag and drop them quickly.

Your headshot isn't one photo. It's a system. When you match the right file to the right digital space, you look prepared, professional, and polished without a second thought. That's the whole point—to let a great impression happen automatically, so you can focus on the conversation itself.
