Headshot Sizes & Dimensions: 8x10, LinkedIn & Aspect Ratios

A "headshot" is not a single size. It is a category of image sizes that vary by industry — acting, modeling, corporate, LinkedIn, casting — and getting the dimensions right matters as much as the photo itself. A perfectly lit, beautifully composed image that arrives at a casting director cropped wrong or pixelated reads as unprofessional, regardless of how good the original capture was.

I have photographed headshots for every industry represented on the South Shore, and the preparation questions are remarkably similar.

This guide covers the standard headshot sizes and aspect ratios used across every common professional context, with the exact dimensions and the reasoning behind them.

The short answer: the standard acting headshot is 8×10 inches — a 4:5 aspect ratio, 2400×3000 pixels at 300 DPI. LinkedIn and most social profiles use a 1:1 square at 800×800 pixels. Modeling comp cards are 5.5×8.5 inches, and corporate bio photos are 1:1 or 4:5 at 1200 pixels or larger. The full reference is below.

Quick Reference: Standard Headshot Sizes

Acting and Casting Headshot Sizes

The 8x10 Standard

Printed acting headshots have used an 8x10 inch format since the studio era, and the standard has not changed. Every theatrical and commercial talent agency in the United States expects the 8x10 format. Every casting workshop reviews submissions at that size. Every casting director who still prints reference materials uses 8x10 boards.

A digital file for a printed 8x10 headshot needs to be 2400 pixels wide by 3000 pixels tall at 300 DPI. Anything smaller will print soft or pixelated; the upper limit is whatever your camera produces (most modern full-frame cameras output 6000+ pixel-wide files). The 8x10 print is also what gets paired with your acting resume — for the conventions on sizing your headshot for casting submissions and how the two documents fit together, see the full headshot-and-resume guide.

Digital Acting Headshots for Casting Platforms

Actors Access, Casting Networks, and Backstage all accept digital headshots, and each has its own minimum:

• Actors Access: 600×900 pixels minimum, 8:12 ratio preferred, JPG only, file size 100KB–2MB
• Casting Networks: 600×750 minimum, 4:5 ratio, JPG/PNG, under 10MB
• Backstage: 800×1000 minimum, 4:5 ratio, JPG/PNG, under 5MB

Always upload at least 2× the platform minimum. These guidelines are years old and the platforms now display larger thumbnails on tablet and mobile.

4:5 vs 8:10 — Same Aspect Ratio, Different Naming

The acting industry sometimes refers to "8:10 headshots" and "4:5 headshots" interchangeably because both describe the same aspect ratio. 8x10 inches reduces to 4:5 when expressed in simplest form. They are identical for cropping purposes — only the unit changes.

LinkedIn Headshot Dimensions

LinkedIn is the highest-volume use case for professional headshots, and the platform's requirements are stricter than most users realize.

Profile Photo Specs

• Minimum: 400×400 pixels
• Recommended: 800×800 pixels (sharper on Retina displays)
• Maximum: 7680×4320 pixels (oversized — no benefit)
• Aspect ratio: 1:1 square (auto-cropped to circle in most views)
• File size limit: 8 MB
• Formats accepted: JPG, PNG

The actual display size on a desktop profile is 200×200 pixels. On mobile, it shows as 152×152. But uploading at 800×800 lets LinkedIn render sharply on high-DPI screens and protects against future resolution increases without re-uploading.

The Circle Crop Problem

LinkedIn crops profile photos to a circle in feed views, search results, and message previews. The corners of your uploaded square are invisible in those contexts. If your photographer composed a tight portrait that uses the full 1:1 square, parts of your hair, shoulders, or background may get cut off in the circle crop.

The workaround: keep your face centered in the inner 70% of the square. Anything in the outer corners will be cropped away when LinkedIn renders the circle.

LinkedIn Cover Photo

The banner image behind your profile photo is a separate spec:

• Recommended: 1584×396 pixels
• Aspect ratio: 4:1 (very wide)
• File size: under 8 MB

Modeling Headshot and Comp Card Sizes

Modeling agencies have different submission requirements than acting, and the dimensions reflect different downstream uses.

Agency Comp Cards

A printed comp card is 5.5×8.5 inches — about half a US letter sheet. The card typically has:

• Front: one large headshot, occupying about 60% of the card face
• Back: 3–4 smaller portfolio images plus stats (height, measurements, hair/eye color, sizes, agency contact)

The headshot on the front needs high resolution — 1650×2550 pixels at 300 DPI — because comp cards are printed with sharp detail review by casting directors who look at them closely. A low-resolution headshot on a comp card is one of the fastest ways to look unprofessional.

Digital Modeling Submissions

For email or web-form submissions to modeling agencies:

• Submission headshot: 1200×1500 pixels minimum, 4:5 aspect ratio
• Polaroid digitals: 800×1000 pixels minimum, against a plain background, minimal makeup, natural hair
• Portfolio gallery images: 2000×2500 pixels for best display in agency-side review tools

Corporate Bio and Website Headshot Sizes

Corporate website bio headshots have no industry-wide standard, but practical norms have emerged:

• Small team-page thumbnail: 300×300 to 500×500 pixels (1:1)
• Bio-page hero: 800×1000 to 1200×1500 pixels (4:5)
• Press kit / media use: 2000×2500 pixels minimum (high res for downstream print)
• Speaker page: 1200×1200 pixels (1:1) — accommodates conference program use

If your company has a brand guide that specifies dimensions, use those. If it does not, request your photographer deliver in both 1:1 and 4:5 crops from the same source frame — that covers most downstream uses without re-cropping.

Aspect Ratios Explained

Most headshot conversations involve one of four aspect ratios:

• 1:1 (square) — LinkedIn, Twitter/X, Instagram profile, most social platforms, corporate team grids
• 4:5 (vertical) — Acting headshots (printed at 8×10), Instagram feed posts, modern corporate bios, modeling digital submissions
• 3:4 (vertical, slightly wider than 4:5) — Some casting platforms, older print formats
• 2:3 (vertical, wider still) — Magazine layouts, environmental portraits, rarely used for traditional headshots

The relationship: 4:5 is narrower than 3:4, which is narrower than 2:3. The narrower the aspect ratio, the tighter the crop sits around the face.

File Format and Resolution

For printed headshots, always deliver at 300 DPI — the standard for offset and digital print. Lower resolutions produce soft, pixelated prints regardless of how sharp the original capture was.

For digital-only use, 72 DPI is the legacy web standard, but 150 DPI is recommended now to handle Retina and 4K displays. JPG at high quality (80–95% compression) is the standard format. PNG is acceptable but produces files 3–5× larger than JPG without visible benefit for photography.

Color space should be sRGB for any web or screen use. Adobe RGB or ProPhoto RGB will display with washed-out colors on most web browsers, which still default to sRGB.

Common Cropping Mistakes

Too Tight

Cropping into the forehead or shoulders to fit a square format on LinkedIn or Instagram looks claustrophobic and amateurish. Always leave breathing room: the top of the frame should sit 5–10% above the head, and the bottom should include at least the upper chest.

Wrong Aspect Ratio for the Platform

Uploading a 4:5 vertical headshot to a 1:1 LinkedIn slot means LinkedIn will auto-crop — and rarely in the way you would choose. Either pre-crop to 1:1 before upload, or use LinkedIn's positioning tool to set the crop manually.

Resolution Too Low

A 400×400 LinkedIn photo looks sharp on a 200×200 display, but the moment LinkedIn enlarges it (your "About" view, the chat-message header, the search result preview), it goes soft. Always upload at the largest recommended size, not the minimum.

Off-Center Face

Casting and modeling submissions especially expect the face centered horizontally in the frame, with the eyes positioned about one-third from the top. Faces shifted left or right of center read as poorly composed even to non-photographers.

When to Request Multiple Crops

If you are paying for a professional headshot session, ask the photographer to deliver:

• One 1:1 square crop — for LinkedIn, social profiles, team pages
• One 4:5 vertical crop — for Instagram feed, modern bios, print use
• One full uncropped frame — for downstream uses your photographer did not anticipate

Most professional studios — including Photography Shark — deliver in multiple crops by default. If yours does not, ask.
