The Complete Guide to Social Media Image Sizes in 2026

Updated on May 25, 2026

Let's be honest — nothing is more frustrating than spending an hour designing a beautiful banner, uploading it to Instagram, and watching the platform chop off your logo like a bad haircut. Social media platforms are ruthless about image dimensions, and they update their requirements without sending you a memo.

I've put together this cheat sheet after going through the pain myself — blurry profile photos on LinkedIn, profile pictures that look fine in the app but terrible on desktop, Facebook covers that shift weirdly on mobile. This guide covers every major platform as of mid-2026, plus the actual mistakes that'll cost you reach and credibility.

Why Image Sizes Still Matter More Than Ever in 2026

Algorithms on every platform now factor in image quality signals. A pixelated or incorrectly cropped image doesn't just look bad — it can suppress your post's distribution. With more content competing for attention, platforms are quietly demoting posts that look low-effort. Getting your dimensions right is table stakes, not optional polish.

Instagram — The Pickiest Platform of Them All

Instagram has more image format variations than any other platform, and they all matter depending on where your content lives.

  • Profile photo: Upload at 320×320 px minimum. Instagram displays it at 110×110 px on mobile, but the original is used for Stories and Highlights covers — so upload larger.
  • Square feed post: 1080×1080 px (aspect ratio 1:1). Still the safest choice for general content.
  • Portrait feed post: 1080×1350 px (4:5 ratio). This takes up more vertical screen space and performs better — use it for product shots and announcements.
  • Landscape feed post: 1080×566 px (1.91:1). Useful for panoramic shots, but you lose screen real estate.
  • Stories & Reels thumbnail: 1080×1920 px (9:16). Keep critical content within the center 1080×1420 px — the top and bottom 250 px are often covered by the UI.
  • Carousel posts: Each slide should match — either all 1:1 or all 4:5. Mixing ratios in a carousel causes jarring crop shifts between slides.

Facebook — Still Confusing, Still Important

Facebook's image specs are a mess because what displays on desktop is often different from mobile, and the platform compresses JPEGs aggressively.

  • Profile photo: 170×170 px on desktop, 128×128 px on mobile. Upload at least 400×400 px so it doesn't get muddy.
  • Cover photo (personal): 820×312 px on desktop, 640×360 px on mobile. Design with a safe zone — keep text away from the left side on desktop since your profile photo overlaps there.
  • Cover photo (Page/Business): 820×312 px desktop, 640×360 px mobile. Same deal, different overlap position.
  • Feed image post: 1200×630 px. Facebook will compress anything over 100 KB — save as PNG for graphics/logos, JPEG for photos, and keep file size in mind.
  • Event cover: 1920×1005 px. Facebook crops this differently depending on where it's displayed, so center your key visuals.
  • Facebook Story: 1080×1920 px — same as Instagram Stories.

X (Twitter) — Cleaner Specs, Fewer Surprises

  • Profile photo: Display is 400×400 px; circular crop. Upload square, keep faces/logos centered.
  • Header/banner: 1500×500 px. The platform crops differently on mobile vs desktop — keep the center third safe for logos and text.
  • In-feed image (single): 1600×900 px or 1200×675 px. The platform previews a cropped version in the timeline — the 16:9 ratio avoids unexpected cuts.
  • In-feed image (two images): Each will be cropped to roughly 1:1 in the preview. Design both as squares before uploading.
  • Maximum file size: 5 MB for images. PNG, JPG, GIF, and WebP all supported.

LinkedIn — The Most Underestimated Platform for Visual Quality

LinkedIn users scroll slower and read more carefully than on other platforms. A poorly sized image here damages professional credibility directly.

  • Profile photo: 400×400 px minimum, square. LinkedIn displays it in circles but stores it square — upload with a clear face and no busy background.
  • Background/banner photo: 1584×396 px (4:1 ratio). This is often overlooked but it's visible on your profile before anything else. Make it count.
  • Feed post image: 1200×627 px for landscape, 1200×1200 px for square. LinkedIn does not aggressively crop in-feed, but it will compress JPEGs — save graphics as PNG.
  • Company page logo: 300×300 px square. Displays at smaller sizes in feed but needs to look clean at full size for brand pages.
  • Company page cover: 1128×191 px. Very wide and short — don't put important content near the edges.
  • Article cover image: 1200×644 px. This is displayed prominently — treat it like a blog hero image.

YouTube — Think Thumbnails and Channel Art

  • Channel profile photo: 800×800 px. Displays as a circle across YouTube and Google products.
  • Channel banner: 2560×1440 px — this is the full file. Safe zone for all devices is the center 1546×423 px. Design in layers: desktop sees more, TV sees full, mobile sees only the center strip.
  • Video thumbnail: 1280×720 px (16:9). This is the most important image on the platform for click-through rate. File size limit: 2 MB.

Pinterest — Vertical is King

  • Standard pin: 1000×1500 px (2:3 ratio). Pinterest is vertically oriented — landscape images get buried.
  • Profile photo: 165×165 px circular crop — upload at 600×600 px.
  • Board cover: 222×150 px — small but visible on profile. Use clean, recognizable imagery.
  • Story pin: 1080×1920 px (9:16), same as other platforms' Stories formats.

TikTok — Mobile-First, No Compromises

  • Profile photo: 20×20 px minimum display, but upload 200×200 px minimum. Circular crop.
  • Video cover/thumbnail: 1080×1920 px (9:16). Vertical, always. If you're using static images in TikTok ads, stick to 9:16.
  • In-feed ad image: 1080×1920 px or 1080×1080 px. Keep text below 20% of the frame — TikTok has a text overlay policy for ads.

12 Sizing Mistakes That Kill Your Content

  1. Uploading landscape images to Instagram Stories. It won't fill the screen — you'll get blurry blurred edges or black bars. Always use 9:16.
  2. Ignoring the Facebook cover mobile shift. The image is positioned differently on desktop vs mobile. Preview both before publishing.
  3. Using PNG for every image on Facebook. PNG files are often large and Facebook compresses them hard. For photos, JPEG at 80% quality exports sharper results.
  4. Putting text near the edges of YouTube channel art. It gets cut off on every device except a widescreen monitor. Stay in the safe zone.
  5. Designing thumbnails at 1920×1080 px. YouTube thumbnails only need 1280×720 px. The larger size just wastes the 2 MB file limit.
  6. Uploading a horizontal logo as a Pinterest pin. Horizontal images on Pinterest get minimal feed space. Vertical always wins there.
  7. Using the same image across all platforms without resizing. An image cropped for Facebook at 1200×630 will look wrong on Instagram, weird on LinkedIn, and cut off on Pinterest.
  8. Mixing aspect ratios in an Instagram carousel. The platform snaps between slides and a ratio mismatch causes a jolting reframe. Lock to one ratio per carousel.
  9. Not checking the profile photo safe zone. Circular crops on LinkedIn, Instagram, and Twitter cut corners — always center your subject and preview the circle before going live.
  10. Low-resolution logos on LinkedIn. LinkedIn keeps both desktop and mobile users — a blurry 150px logo on a company page damages trust before someone reads a single word.
  11. Forgetting that Stories have UI overlays. The top ~250 px and bottom ~250 px of Stories on Instagram and Facebook are covered by usernames, CTAs, and reactions. Never put critical content there.
  12. Using GIFs for profile photos on platforms that don't support animation. Facebook and LinkedIn will just grab the first frame. You'll end up with a weird freeze-frame instead of the looping animation you expected.

The Fastest Way to Resize Without Losing Quality

You don't need Photoshop for this. A good image resize tool handles batch exports across dimensions in seconds — key things to look for: lossless upscaling support, preset export profiles for specific platforms, and the ability to convert between PNG/JPG/WebP in the same workflow. WebP in particular is worth using for web-hosted images since it's roughly 30% smaller than JPEG at the same quality level, and all major platforms accept it now.

When cropping, always crop from the center-out first, then adjust. That way you're not losing faces or product details to a hasty trim.

When in doubt, bigger is better as long as you stay within file size limits, and always export at 72 DPI for screens (higher DPI adds file size without any visible benefit on displays).
