What size should a LinkedIn headshot be?

At least 400 × 400 pixels, uploaded as a square. For the sharpest result on high-resolution screens, use 800 × 800 or larger, under 8 MB.

What are standard headshot dimensions?

The most common professional standard is a 3:4 portrait (for example 1200 × 1600 pixels). From that one master file you can crop a square for LinkedIn and smaller sizes for signatures and directories.

Why does my LinkedIn headshot look blurry?

Usually the source file is too small or was compressed by a messaging app. Start from the original full-resolution photo, crop to a square, and don't zoom in past the pixels you have.

Can I use the same photo for LinkedIn, my CV, and a hospital directory?

Yes — keep one high-resolution 3:4 master and crop per platform. That keeps your look consistent everywhere, which is exactly what you want for professional recognition.

What resolution does an AI headshot need to be?

MedshotsAI generates photos at 4K resolution, which comfortably covers LinkedIn, print CVs, directory pages, and conference materials without any upscaling tricks.

LinkedIn Headshot Size: Exact Dimensions in Pixels (2026 Guide)

Short answer: upload a square photo that's at least 400×400 pixels to LinkedIn, and keep a high-resolution 3:4 master copy for everything else.

That's it. That's the secret. But since 'my photo looks blurry and I don't know why' is one of the most common headshot complaints on the internet, let's go one level deeper.

Below are the exact numbers for every place a professional headshot ends up — LinkedIn, your CV, hospital directories, residency applications, and that email signature you set up once in 2019.

One sharp master photo covers every platform

Dimensions matter, but they can't rescue a weak source photo. Start from one high-resolution professional headshot like this and every crop on this page — LinkedIn, CV, directory — comes out clean.

LinkedIn headshot dimensions (the exact numbers)

LinkedIn displays your profile photo as a circle, but it stores a square. Here's what matters:

Minimum size: 400 × 400 pixels — below this, LinkedIn will still accept the photo, but it will look soft
Recommended: 800 × 800 pixels or larger, so it stays sharp on retina screens
Maximum file size: 8 MB (JPG or PNG both work fine)
Shape: upload a square — LinkedIn crops it into a circle, so keep your face centered
Your face should fill roughly 60% of the frame, with a little space above your head

Why your LinkedIn photo looks blurry

Nine times out of ten, it's one of these three things: the source file was tiny (a photo cropped out of a group shot, say), the photo was compressed by being sent through a messaging app, or you zoomed way in while cropping.

The fix is boring but reliable: start from the original, full-resolution file. If someone texted you the photo, ask for the original instead. WhatsApp and iMessage quietly squeeze the life out of images.

Headshot dimensions for everything else

The smart move is to keep one high-resolution 'master' headshot — 3:4 portrait orientation, at least 1200 × 1600 pixels — and crop copies from it as needed. Here's your cheat sheet:

LinkedIn profile: 400 × 400 px minimum, square (800 × 800 recommended)
CV or resume: about 300 × 400 px printed area — a 3:4 crop scales perfectly
Hospital directory / practice website: varies by site, but a 3:4 or square crop at 800+ px wide covers virtually every CMS
ERAS residency photo: commonly requested at 2.5 × 3.5 inches, passport-style — check the current ERAS guide before uploading
Email signature: small — around 100 × 100 to 150 × 150 px — so start sharp or it becomes a smudge
Zoom / Teams avatar: square, 512 × 512 px is plenty

Square vs 3:4 — which should you keep?

Both. Seriously. Save your master headshot as a 3:4 portrait (that's what photographers and hospital directories prefer), then make one square copy for LinkedIn, Zoom, and social profiles.

If cropping isn't your idea of a good evening, our free LinkedIn Photo Optimizer does the crop for you, and the Multi-Platform Resizer spits out every size at once.

One more thing: dimensions can't fix a weak photo

Perfect pixels won't rescue a dim bathroom selfie. If the underlying photo is the problem, you can generate a clean, professional headshot from one selfie with MedshotsAI — it comes out at 4K, which is more than enough pixels for every platform on this list at once.
