Half the photos people upload to social media in 2026 are the wrong size. They get cropped at the worst possible moment — the top of someone's head sliced off in a LinkedIn banner, a YouTube thumbnail blurred into mush because it was saved at 640 pixels wide, an Instagram carousel that looks great on the first slide and tragic on the second. This is the practical, no-nonsense reference I wish I'd had when I started running social accounts. It covers every social media image size for 2026 — Instagram, Facebook, LinkedIn, YouTube, X (Twitter), TikTok and Pinterest — with the dimensions that actually display correctly today, not the ones you'll find on a 2019 blog post that's been autoupdated by an AI. Every recommendation is paired with a free ImageGates resizer you can use in your browser, fast online processing, no upload. Bookmark this page; the platforms will tweak things again next quarter and we update it the day they do.

Why image dimensions actually matter in 2026

Most people treat image size as a cosmetic detail. It isn't. Every major platform now runs its feed through a recommendation system that scores posts in the first 60 seconds based on early engagement — taps, dwell time, profile visits. A photo that displays as a cropped letterbox on mobile gets fewer of all three. A LinkedIn cover that hides your job title behind the profile picture circle quietly costs you a third of your impressions because nobody clicks through to read your headline. A YouTube thumbnail uploaded at 720 pixels wide is upscaled by the player and the slight softness is the difference between a 4% click-through rate and a 7% one. None of these failures show up as a warning. The platform just gives you less reach and you assume the content was the problem.

The other reason dimensions matter is that the cost of getting them right is essentially zero. A correctly sized 1080×1080 Instagram post compresses to under 200 KB, uploads in two seconds, and looks identical on a phone and a desktop. A 4032×3024 photo straight from an iPhone takes ten times longer to upload, gets recompressed twice by Instagram's pipeline, and arrives on the viewer's screen looking softer than the version you cropped yourself. The platform's resizer is the worst resizer on the internet because it has to handle a billion uploads a day and cannot afford to be careful. Yours can be. That's the entire argument for taking thirty seconds to resize an image to the correct dimensions before you post it.

Three forces shape every recommendation in this guide:

Mobile-first display. Over 90% of all social media views happen on a phone. Square (1:1) and portrait (4:5, 9:16) crops take up more vertical real estate than landscape and consistently outperform them.
Safe zones. Every cover image gets covered. A LinkedIn banner has the profile picture sitting on the bottom-left. A Facebook cover has the profile picture on the bottom-center on desktop and bottom-left on mobile. Put nothing important where the circle will land.
Format vs compression. JPG is universal, small, and lossy. PNG is lossless but two to four times bigger. WebP is supported everywhere except a handful of CMSes. For social media, JPG at quality 85 is the right answer 90% of the time — use PNG only when you need a transparent logo overlay.

Instagram image sizes

Instagram is the most format-sensitive platform on this list. The feed allows three aspect ratios — square, portrait, and landscape — but they don't behave equally. Portrait posts (4:5) take up roughly 25% more vertical screen than square posts, which means more attention per scroll. Landscape posts (1.91:1) display the smallest. Stories and Reels are full-screen vertical 9:16 and treat anything narrower as a letterbox with grey bars on the sides — the kiss of death for a Reel's watch time.

Instagram feed post

Square: 1080×1080 pixels (1:1) — the safe default that looks identical to everyone.
Portrait: 1080×1350 pixels (4:5) — the actual best-performer in 2026, takes up the most feed space.
Landscape: 1080×566 pixels (1.91:1) — only use when the photo is genuinely horizontal (e.g. a sunset).

Use the 1080×1080 resizer for square posts, or the general Instagram image resizer for portrait and landscape. Save as JPG, quality 85–90, target file size 150–250 KB. Instagram re-encodes everything anyway, but starting from a clean, correctly sized file means the second pass introduces less artefacting.

Instagram Stories

Stories are 1080×1920 pixels (9:16). This is the same as a full-HD vertical video frame. The top 250 pixels and bottom 250 pixels are the "safe zone" — the area where Instagram overlays your username, the reply box, and the navigation dots. Put your key text and faces inside the middle 1080×1420 rectangle or they will be partially hidden. Stories accept JPG and PNG; if your story has flat colour graphics or text, PNG keeps text edges crisp. If it's a photograph, JPG at 90 quality is smaller and indistinguishable.

Instagram Stories are 1080×1920 with a 250-pixel safe zone top and bottom.

Instagram Reels

Reels share the Story dimensions — 1080×1920, 9:16 — but the safe zone is different. Instagram puts the caption, like/comment/share icons, and the audio strip along the right side and the bottom third. If you put a face in the bottom-right corner, half of it will sit behind the heart icon. Composing for the centre-left of the frame is the single trick that separates Reels that get reshared from ones that get scrolled past.

Instagram profile photo

The profile photo uploads at 320×320 pixels and is displayed in a circle of about 110×110 on most surfaces. The corners get cut off, so a square logo with content edge-to-edge will lose its corners. Centre the subject in the middle 70%. Remove the background if it's a portrait — a clean coloured backdrop reads better at thumbnail size than a busy environment.

Instagram carousel posts

Carousels can mix 1:1 and 4:5 — but only with each other on the same post, and the first slide's aspect ratio defines the frame for all subsequent slides. Pick portrait (1080×1350) for the first slide if you want the full carousel to display tall. Once locked, every following slide is also displayed at 1080×1350 even if it was uploaded square; the square will be letterboxed with white bars. Get this wrong and slide 2 looks like a mistake.

Facebook image sizes

Facebook is unusual in that its image system was designed for desktop in 2012 and has been patched, never rebuilt, for the mobile era. That's why the cover photo dimensions are so awkward and why what you see in the Pages editor is not what you see on a phone. The numbers below are the ones that look correct on both.

Facebook profile picture

Upload at 320×320 pixels minimum, 720×720 recommended for retina screens. Displays as a circle at 170×170 on desktop and 128×128 on mobile. The corners get cropped — keep the subject centred and tightly framed. Profile pictures appear next to every post you make, so a recognisable face or logo is worth more than a clever composition. Use the Facebook image resizer to crop it square first.

Facebook cover photo

This is the trap. The cover photo is 851×315 pixels on desktop but Facebook crops it to 640×360 on mobile — a different aspect ratio. Anything within 90 pixels of the left or right edge will be cut off on phones. The safe zone — the rectangle visible on both — is roughly 640×315 in the centre. Design your cover at 851×315 but keep all logos, faces, and text inside the centre 640×315. Save as JPG at quality 90, target under 400 KB. PNG is allowed but Facebook converts it to JPG anyway.

Facebook cover at 851×315 desktop — keep content inside the centre 640 wide.

Facebook feed posts

Single image, landscape: 1200×630 pixels (1.91:1) — also the og:image standard for link previews.
Single image, square: 1080×1080 — works fine, less common.
Single image, portrait: 1080×1350 (4:5) — same advantage as Instagram, takes more feed space.

Use 1200×630 for anything you also want to share as a link preview — the same image will appear when someone pastes your URL anywhere.

Facebook Stories

Identical to Instagram: 1080×1920, 9:16. Facebook and Instagram share the Meta back-end, so you can cross-post the same vertical asset to both without re-exporting.

Facebook Group covers

1640×856 pixels (1.91:1). Mobile crops to roughly 1640×540 in the centre. Larger than the Page cover, with different safe-zone maths, but the same rule applies: keep critical content in the centre band.

LinkedIn image sizes

LinkedIn has the highest professional stakes per pixel of any platform. A recruiter spends roughly 7 seconds on a profile before deciding to scroll on, and most of that time is spent looking at the banner-plus-photo composition. Get the dimensions right and your headline gets read; get them wrong and you've spent a year of work hidden behind an off-centre circle.

LinkedIn profile picture

Upload at 400×400 pixels minimum, 800×800 recommended. Displays as a circle at 200×200 on desktop, 152×152 on mobile. LinkedIn now darkens and slightly desaturates profile photos in the feed (a 2024 anti-fake-profile measure that persists in 2026) so high-contrast portraits read better than soft-light ones. Use the background remover to put yourself on a clean colour, then export square JPG.

LinkedIn personal banner

1584×396 pixels (4:1). The profile picture circle sits over the bottom-left at roughly the 130–330 pixel column range. Keep all text in the right two-thirds of the banner. On mobile, the banner is cropped to roughly 1584×220 in the centre — so put nothing critical in the top or bottom 80 pixels. Use the dedicated LinkedIn image resizer for the safe-zone overlay.

LinkedIn personal banner is 1584×396 with the profile circle covering the bottom-left.

LinkedIn company page banner

1128×191 pixels — a much flatter rectangle than the personal banner. The logo sits on the bottom-left at 60×60 in a rounded square. Mobile crops to roughly 1128×120 — so the safe zone is tight. Avoid stacked text; one short tagline reads better.

LinkedIn post images

Single image: 1200×627 pixels (1.91:1) for landscape, or 1200×1500 for portrait.
Document/PDF carousel: 1080×1080 per page, but 1080×1350 portrait is the format LinkedIn's algorithm has clearly favoured for the past 18 months.
Link preview: uses og:image at 1200×627. If your blog uses different dimensions, LinkedIn will crop unpredictably.

LinkedIn compresses uploads aggressively. Start from a sharp source and accept that the version on-platform will be 60–70% of your original file size.

YouTube image sizes

YouTube is a thumbnail business. The video itself converts viewers but the thumbnail is what wins the click in the first place, and the dimensions matter more than the design. A blurry thumbnail loses to a sharp one even when the design is worse.

YouTube video thumbnail

1280×720 pixels (16:9), JPG, under 2 MB. This is non-negotiable — YouTube literally rejects uploads below 640 pixels wide. But the platform recommends 1280×720 because that's the size displayed on every surface from the watch-page sidebar to the mobile home feed. Upload at 1280×720 exactly and you avoid the upscaler. Upload at 1920×1080 and YouTube downscales — usually fine, sometimes slightly soft on text. Use the YouTube thumbnail resizer to lock the aspect.

A correctly sized 1280×720 thumbnail (right) reads at every YouTube size; an upscaled one (left) softens.

Three thumbnail rules I have never seen broken by a channel that grew past 100k subscribers: faces beat objects, three colours beat seven, and text bigger than 80 pixels tall reads on mobile while smaller text doesn't.

YouTube channel banner

2560×1440 pixels (16:9). YouTube displays this at very different sizes depending on the device — full 2560×440 on a TV, roughly 2560×1440 only on the channel page itself, and a tight 1546×423 on mobile. The safe zone where text and logos display on every device is the centre 1546×423. Design at 2560×1440 with all critical content within that centre rectangle.

YouTube community post images

1080×1080 square for image posts; 1280×720 if you want to mimic the thumbnail format. Community posts have small previews so square reads best.

X (Twitter) image sizes

X has the messiest image system of the major platforms. The feed displays the same image at different aspect ratios depending on whether it's a single image, two images, three, or four. The recommendations below assume single-image posts, which still outperform multi-image ones by a wide margin in the algorithm as of 2026.

X profile photo

400×400 pixels, displays as a circle. Same advice as LinkedIn and Instagram — centre tight, simple background.

X header

1500×500 pixels (3:1). The profile picture circle sits on the bottom-left and covers roughly the first 220 pixels of the bottom edge. Mobile preserves the full ratio but at lower resolution — there is no separate mobile crop on X, which is the one thing the platform got right. JPG, under 5 MB.

X header at 1500×500 — keep content out of the bottom-left where the profile circle sits.

X post images

Single image, landscape: 1600×900 pixels (16:9) — displays uncropped in the feed.
Single image, square: 1080×1080 — also uncropped, takes slightly less feed space.
Single image, portrait: 1080×1350 — X crops to 16:9 in the feed but the full image displays on tap. Good for memes with the punchline at the bottom.
Two images: each cropped to 1:1 side-by-side.
Three or four images: each cropped to landscape strips. Avoid for anything where the crop matters.

X re-encodes JPG aggressively. PNG survives slightly better for screenshots of text — a tweet of a code block looks measurably sharper as PNG than JPG.

TikTok image sizes

TikTok is video-first but image carousels (Photo Mode) have grown into a serious share of feed time. The dimensions are vertical-only.

Profile photo: 200×200 pixels, displays as a circle.
Video frame / cover image: 1080×1920 (9:16). The cover is the still frame people see in the For You grid — pick or upload a frame with a face large in the centre.
Photo Mode carousel: 1080×1920 per image, JPG. The first slide is what stops the scroll.

Anything wider than 9:16 is letterboxed with blurred bars top and bottom. The blur looks fine in theory but viewers swipe past it twice as fast as they swipe past full-bleed content. Always export vertical.

Pinterest image sizes

Pinterest is the longest-lived image platform on this list and still the most rewarding for evergreen content. Pins keep getting clicks years after upload — a useful counterpoint to Instagram, where a post is invisible after 48 hours.

Standard Pin: 1000×1500 pixels (2:3) — the format the algorithm overwhelmingly prefers.
Square Pin: 1000×1000 — accepted but less click-through than 2:3.
Long Pin: 1000×2100 (roughly 1:2.1) — used to be discouraged, now mildly favoured for infographics again.
Profile photo: 165×165 pixels, displays as a circle.
Board cover: 217×147 pixels minimum, displayed at variable sizes.

Pinterest is the one platform where PNG is genuinely worth using — pins with crisp typography against flat colour read like posters, and the pinning experience tolerates the larger file size. Aim for 200–600 KB per pin.

Common image resizing mistakes (and how to avoid them)

A stretched-to-fit image (left) destroys faces. Correct aspect-ratio cropping (right) preserves them.

Stretching instead of cropping. The classic. You force a landscape photo into a square slot and the subject's face widens. Always crop to the right aspect ratio first, then resize. The image cropper with locked-aspect handles this in one click.
Upscaling small images. If your source is 600 pixels wide and the platform wants 1280, no resizer can invent the missing pixels. The result is soft. Always start with a source larger than the target.
Wrong format for the content. Saving a screenshot of text as JPG makes the letters ghosty. Saving a photograph as PNG triples the file size with no visible benefit. Use JPG for photos and PNG for graphics with text.
Ignoring file size limits. LinkedIn caps post images at 5 MB; over that, the upload silently fails or strips metadata. Compress to under 1 MB and you're safe on every platform.
Compositing at the wrong resolution. Designing a Story in a 360×640 Canva preview and exporting at that size means everyone sees a soft, upscaled version. Design at the actual target size — 1080×1920 — from the start.
Forgetting safe zones. Especially on LinkedIn banners and Facebook covers. Test on a mobile phone before posting. If you can't see your tagline on a 6-inch screen, neither can your audience.

How to resize images for social media without losing quality

The workflow that consistently produces clean uploads is short:

Start large. Begin with the highest-resolution source you have — the original camera file, not a screenshot. You can always go down; you can never go up.
Crop to the target aspect ratio first. Use the crop tool with the lock set to the destination (1:1 for Instagram square, 9:16 for Stories, 16:9 for YouTube). Composition decisions belong here, not in the resizer.
Resize to the exact pixel dimensions. Open the image resizer, type the platform's exact width and height, and export. Don't rely on "scale to fit" — type the numbers.
Optional: clean up the background. Profile photos benefit enormously from a flat colour behind the subject. The background remover takes about 6 seconds.
Convert format if needed. If the source is a HEIC from iPhone or a WebP from a screenshot, run it through the JPG converter first — some platforms still struggle with HEIC.
Compress. Use the compressor to target 80–90% quality. The visual difference is invisible; the file size drop is huge.

The whole resize-crop-compress workflow takes under two minutes per image.

Everything in that workflow runs locally in your browser at ImageGates. No upload, fast online processing, high-quality results. Your original photo never leaves your device — which matters when the image is a passport scan, a contract screenshot, or a half-finished product mockup you don't want sitting on someone else's server.

One last note on platform compression. Even when you do everything right, the platform will re-encode your image on its end. There's nothing you can do about that. What you can do is give it the cleanest possible source — correct dimensions, lightly compressed, sharp — so that the platform's second pass has less work to do and introduces fewer artefacts. That's the entire game.
