Social Media Image Sizes: The 2026 Cheat Sheet

You spent an hour making the graphic. The colors sing, the headline lands, the logo sits just so. You upload it, hit publish, and… the top of your title is gone. Your face is half-cropped by the profile ring. That crisp export now looks like it went through a car wash. If you’ve ever felt that specific flavor of Tuesday-morning betrayal, welcome — you’re in exactly the right place.

Here’s the good news: getting social media image sizes right isn’t about memorizing 60 magic numbers. It’s about understanding a handful of aspect ratios, respecting a few safe zones, and exporting clean. Nail those, and your work looks sharp everywhere — profile, feed, story, cover, all of it. This is the master cheat sheet of social media image sizes I wish someone had handed me years ago, organized so you can bookmark it and actually use it on deadline.

One honest note before we dive in: platforms change their specs quietly and often. The dimensions below reflect commonly documented, widely used specs — but treat them as a smart starting point, not gospel. Always spot-check against the platform’s current help docs before a big launch. I’ll show you how to build in a margin of safety so a small spec change never wrecks your design.

First, the three ideas that make every number make sense

Nearly all of the confusion around social media image sizes melts away once these three ideas are in place. Before the tables, internalize these concepts. Once they click, you’ll be able to reason your way to the right size even when you can’t find this page.

1. Aspect ratio beats exact pixels

An aspect ratio is the shape of your image — width to height — written like 1:1 (a square), 4:5 (a tall portrait), 16:9 (a wide landscape), or 9:16 (a full vertical). Platforms care far more about the ratio than the precise pixel count, because they resize your image to fit their layout. If you give them the right shape at a generous resolution, you’re 90% of the way there. Give them the wrong shape and they’ll crop or pad it — that’s where heads get chopped and awkward gray bars appear.

The ratios you’ll actually use, memorize these five:

• 1:1 — square. The dependable workhorse for feed posts and profile-adjacent graphics.
• 4:5 — portrait. Takes up more vertical space in mobile feeds without getting cropped. Great for Instagram and Facebook feed.
• 9:16 — full vertical. Stories, Reels, TikTok, Shorts — the whole phone screen.
• 16:9 — widescreen landscape. YouTube thumbnails and video, plus link previews and many cover images.
• 1.91:1 — wide landscape. The standard link-preview and horizontal feed ratio across several networks.

2. Safe zones keep your content from getting eaten

A safe zone is the region of your image guaranteed to stay visible and unobstructed. On a Story or Reel, the top and bottom — roughly the top and bottom 250 pixels of a 1080×1920 canvas — get covered by the profile icon, caption, and action buttons. On a profile photo, the corners get clipped because the image displays as a circle. On a cover or banner, the sides or edges may be cropped differently on desktop versus mobile. The fix is simple: keep your critical stuff — text, logo, faces — comfortably in the center, and let the edges be “bleed” you won’t cry over.

3. Bigger and cleaner beats tiny and stretched

Upload at the platform’s recommended resolution or a clean multiple of it, not a shrunken version. Platforms compress everything on upload; if you start small, that compression turns your image to mush. Use a modern format — PNG for graphics with text and sharp edges, high-quality JPG for photos — keep the color profile sRGB, and don’t blow past the file-size ceiling (compression gets more aggressive as you approach it). Start clean and your design survives the trip.

Okay — with those three in your back pocket, here are the recommended social media image sizes, platform by platform.

Instagram image sizes

Instagram is where cropping heartbreak happens most, because it’s phone-first and the feed favors vertical.

• Profile photo: upload around 320×320 px (1:1). It displays as a small circle, so center your logo or face and keep the corners empty.
• Square feed post: 1080×1080 px (1:1). The safe classic — never cropped.
• Portrait feed post: 1080×1350 px (4:5). This is the sweet spot for feed — it claims maximum vertical real estate on a phone without any cropping. When in doubt, design 4:5.
• Landscape feed post: 1080×566 px (1.91:1). Fine, but it looks small in-feed; portrait usually wins.
• Stories & Reels: 1080×1920 px (9:16). Keep text and key subjects in the center; assume the top ~250 px (profile/username) and bottom ~250 px (caption, buttons) may be covered.
• Reels cover thumbnail: design at 1080×1920 but remember the grid crops your cover to roughly a 1:1 center square — so put the title in the middle where both views show it.

If Instagram growth is your main goal, the format you choose matters as much as the pixels — our guide on how to grow on Instagram digs into which post types earn reach, and Instagram Reels ideas can fill your 9:16 canvas when you’re staring at a blank one.

Facebook image sizes

Facebook shows the same image differently on desktop and mobile, so safe zones matter a lot here — especially for covers.

• Profile photo: upload at least 320×320 px (1:1); it displays as a circle on the app and a rounded square in some placements. Center everything.
• Page cover photo: commonly cited around 820×312 px for desktop, but it renders differently on mobile (a taller crop). Keep essential content centered and avoid putting text near the edges. A widely used safe approach is to design large — e.g., 1640×624 px — and keep the important stuff in the middle 60%.
• Feed post (square): 1080×1080 px (1:1).
• Feed post (portrait): 1080×1350 px (4:5) for maximum mobile height.
• Shared link preview: 1200×630 px (1.91:1). This is the image that shows when you paste a link — design it as its own little billboard.
• Stories: 1080×1920 px (9:16), same safe-zone rules as Instagram.

X (Twitter) image sizes

X crops feed images aggressively in the timeline and expands them on click, so the framing you design and the framing people first see can differ.

• Profile photo: around 400×400 px (1:1), displayed as a circle.
• Header / banner: commonly 1500×500 px (3:1). It’s a wide, short strip and the top and bottom edges can be trimmed on some screens — keep text and logos centered vertically.
• In-stream single image: a 16:9 (e.g., 1600×900 px) or 1200×675 px image displays cleanly; the timeline may show a cropped preview, so keep the subject centered. Square (1:1) images also work well and preview with less cropping.
• Link preview card: 1200×628 px (roughly 1.91:1) for the large summary card.

LinkedIn image sizes

LinkedIn skews desktop-heavy, so landscape and square formats read best, and profile banners have their own quirks.

• Personal profile photo: 400×400 px and up (1:1), circular crop.
• Personal profile background banner: commonly 1584×396 px (4:1). Your profile photo overlaps the lower-left on desktop — keep that corner clear of anything important.
• Company page logo: around 300×300 px (1:1).
• Company page cover: commonly cited near 1128×191 px, though a larger 1:4-ish canvas future-proofs it — center your content.
• Feed post image: 1200×1200 px (1:1) or 1200×628 px (1.91:1) both perform well; portrait 1080×1350 also shows nicely on mobile.
• Shared link preview: 1200×627 px (1.91:1).

Pinterest image sizes

Pinterest is the one platform that rewards tall images, because Pins live in a vertical scrolling grid. Going vertical here isn’t optional — it’s the whole game.

• Profile photo: around 165×165 px (1:1), circular.
• Standard Pin: 1000×1500 px (2:3) is the classic recommended ratio. This is your default. A 1080×1920 (9:16) also works for taller Pins.
• Square Pin: 1000×1000 px (1:1) works but takes up less grid space than 2:3.
• Idea Pin / video Pin: 1080×1920 px (9:16), full vertical.

A quick reminder: extremely long Pins may get truncated in-feed, so 2:3 is the reliable balance between height and full visibility.

TikTok image sizes

TikTok is 9:16 to its core. Even carousels and image posts live on that full vertical canvas.

• Profile photo: around 200×200 px (1:1), circular — upload larger for a crisp display.
• Video / image post: 1080×1920 px (9:16). As with Stories, the right side (icons) and bottom (caption, handle) get covered by the interface — keep text and faces centered and away from the bottom third.
• Photo carousel: 1080×1920 px (9:16) per image; you can also use portrait ratios, but full-screen vertical looks most native.

YouTube image sizes

YouTube has more distinct image slots than any other platform on this list — and the channel banner is famously fussy because it displays across TV, desktop, tablet, and phone.

• Channel profile photo: commonly 800×800 px uploaded (1:1), shown as a circle.
• Channel banner / cover art: upload at 2560×1440 px (16:9), but the only region guaranteed to show on every device is the center — the widely used “TV and desktop safe area” is a central strip of about 1546×423 px. Put your channel name, tagline, and logo there and let the rest bleed off-screen on smaller displays.
• Video thumbnail: 1280×720 px (16:9), the single most important graphic you’ll make on YouTube. Keep text large and legible — it’s shown tiny in search and huge on TVs.
• Video itself: 1920×1080 px (16:9) for standard uploads; Shorts are 1080×1920 px (9:16).

The text-first networks: Threads, Bluesky, Mastodon & Tumblr

The newer and more text-centric platforms are refreshingly forgiving about images — but forgiving isn’t the same as free-for-all, and a little care still pays off.

• Threads: profile photos crop to a circle (upload 1:1, at least ~320×320 px), and inline images behave much like Instagram’s feed — a square (1:1) or portrait (4:5) at 1080 px wide displays cleanly. Very wide landscape images get a smaller in-feed preview, so vertical or square reads better on a phone.
• Bluesky: the banner is a wide strip (a 3:1 ratio around 1500×500 px works well), the avatar is circular, and post images preview in the feed with some cropping — keep the subject centered and expect the tap-to-expand view to show the full frame.
• Mastodon: because it’s a federated network of independent servers, exact display can vary slightly by instance and theme, but the header banner commonly follows a wide ratio (roughly 3:1, e.g., 1500×500 px) and the avatar is a rounded square or circle. Attached images preview cropped and expand on click. Design with centered content and you’ll look right across instances.
• Tumblr: the classic dashboard favors images around 540 px wide, so upload at 1080×1350 (or wider) and let it scale down crisply; the header/banner is a wide landscape, and the avatar is a small square. Tumblr is generous with tall images, so vertical work shines.

The through-line across all four: circular or squared avatars want centered subjects, banners are wide strips that crop at the edges, and vertical-or-square in-feed images beat ultra-wide ones on mobile. Same three ideas, different logos.

File formats, color, and the export details that quietly matter

Two graphics at identical dimensions can look wildly different after upload — the difference is almost always in the export settings. Here’s what to lock in:

• Format: use PNG for anything with text, logos, flat color, or sharp edges (it keeps lines crisp), and high-quality JPG for photographs (smaller files, no visible loss). Avoid uploading heavily pre-compressed JPGs — you’ll stack compression on compression and get artifacts.
• Color profile: export in sRGB. Design tools sometimes default to other profiles, and colors that looked rich in your editor can shift dull or oddly saturated once a platform strips the profile. sRGB is the web standard — match it and what you see is what your audience gets.
• File size: stay comfortably under each platform’s ceiling. As your file approaches the limit, compression gets more aggressive, so a slightly smaller, cleaner export often looks better than a maxed-out one.
• Transparency: if you need a transparent background (say, a logo overlay), PNG supports it; JPG doesn’t. But remember most feeds sit on a white or dark background, so preview your transparent asset against both.

A fast reference: which ratio for which job

When you can’t find the exact pixels and you’re on a deadline, reason from ratio and you’ll almost never go wrong:

• Any profile photo → 1:1 square, subject centered, corners empty (it’ll be a circle).
• Any Story / Reel / TikTok / Short → 9:16 at 1080×1920, content in the center, top and bottom ~250 px reserved for the interface.
• Feed post you want to dominate mobile → 4:5 at 1080×1350.
• Universally safe feed post → 1:1 at 1080×1080.
• Link preview / share card → 1.91:1 at ~1200×630.
• YouTube thumbnail or any widescreen slot → 16:9 at 1280×720 (or 1920×1080 for video).
• Pinterest Pin → 2:3 at 1000×1500.

The five mistakes that ruin good graphics

Knowing the sizes is half the battle. Here’s how designs die even when the pixels are right.

1. Text too close to the edge

Every platform crops something — stories cover the top and bottom, feeds crop landscape images, covers behave differently on mobile. Give your text a generous margin. A good rule: keep critical elements inside the center 80% of the canvas. If it feels like there’s too much empty breathing room at the edges, it’s probably right.

2. Designing one size and reusing it everywhere

A 16:9 YouTube thumbnail dropped into an Instagram feed becomes a tiny, letterboxed sliver. A 9:16 Story squeezed into a Facebook link preview gets center-cropped into nonsense. You don’t need a bespoke design for all eleven networks — but you do need a square (1:1), a vertical (9:16 or 4:5), and a landscape (16:9) version of your key assets. Design once at high resolution, then export the three shapes.

3. Uploading a tiny file and letting the platform upscale

Upscaling doesn’t add detail; it invents blur. Always upload at the recommended resolution or larger. Storage is cheap; a fuzzy brand looks amateur.

4. Ignoring the profile-photo circle

Nearly every platform crops profile photos into circles. If your logo is a horizontal wordmark or your headshot is off-center, the circle will slice it. Use a centered mark or a tightly framed face, and test how it looks small — because that’s how everyone sees it.

5. Forgetting to check the current spec before a big launch

Platforms update layouts quietly. The numbers here are commonly documented and reliable as a baseline, but before a product launch, a paid campaign, or a rebrand, spend two minutes confirming the live spec in the platform’s own help center. This one habit saves the most painful re-dos.

Build a repeatable workflow so you never guess again

Here’s the system I’d set up if I were starting today. It takes an afternoon once and saves you every week after.

Step 1 — Build master templates for three ratios. In whatever design tool you use, make a reusable template at 1080×1080 (1:1), 1080×1920 (9:16), and 1280×720 (16:9). Add visible safe-zone guides — a centered box marking the safe 80%, and on the 9:16 template, shaded bars across the top and bottom 250 px. Now every new graphic starts inside guardrails.

Step 2 — Design in the ratio the post will actually use. Decide the destination first, then open the matching template. Designing a Reel? Start 9:16. Designing a LinkedIn carousel? Start square. This one reorder — platform first, design second — eliminates most cropping surprises.

Step 3 — Export clean. PNG for anything with text or crisp edges, high-quality JPG for photo-heavy pieces, sRGB color, comfortably under the file-size limit. Name files by platform and ratio so you never upload the wrong one at 9 PM.

Step 4 — Preview before you commit. Most schedulers show you a real preview of how the image will appear in each network’s feed. Use it. Catching a cropped headline in preview costs ten seconds; catching it after 4,000 people have seen it costs your afternoon.

Step 5 — Batch and schedule. Once your assets are exported and previewed, load a week or a month at once instead of scrambling daily. If you’re building that muscle, our walkthrough on how to schedule social media posts pairs perfectly with this cheat sheet — right size, right time, zero panic.

The one-line version to tape above your desk

If you remember nothing else: square (1:1) is universally safe, vertical (9:16 or 4:5) wins on phones, widescreen (16:9) is for YouTube and covers, and 1.91:1 is for link previews — keep everything important centered, export big and clean, and preview before you post. Master those and you’ll never again watch a platform behead your carefully placed headline.

Sizes are just the foundation, though. Getting your social media image sizes right gets you seen; what you do with that canvas is what earns the follow.
