Social Media Image Sizes for Every Platform in 2026

If you've ever uploaded a beautifully designed graphic only to see it cropped into something unrecognisable, you already know the problem. Social media platforms don't care how long you spent in Canva — they'll crop to their specs whether you like it or not.

Here's a quick answer first: the most commonly needed sizes are YouTube thumbnail: 1280×720px, Instagram post: 1080×1080px (square) or 1080×1350px (portrait), LinkedIn banner: 1584×396px, and Twitter/X header: 1500×500px. Keep reading for the full breakdown by platform, plus tips on how to make one design work across all of them.

Direct answer. Every major platform has a different required image size, and uploading the wrong dimensions causes cropping, compression, or silent quality loss. The four ratios that cover almost everything are 16:9 (YouTube, Twitter, Facebook), 1:1 (Instagram square, LinkedIn post), 4:5 (Instagram portrait feed), and 9:16 (Stories, Reels, TikTok, Snapchat). Design to these ratios; the pixel counts are secondary.

YouTube Thumbnail Size

YouTube thumbnails are one of the highest-ROI visuals in your content library. A well-made thumbnail directly affects click-through rate, which directly affects how much YouTube promotes your video.

Spec	Value
Recommended size	1280 × 720 px
Minimum width	640 px
Aspect ratio	16:9
Max file size	2 MB
Formats	JPG, PNG, WebP, GIF

Design tip: YouTube compresses thumbnails heavily on mobile. Use high-contrast colours, large text (if any), and avoid small details that disappear at small sizes. The most clickable thumbnails have a clear subject centre-frame and a single visual hook — not a collage of five things.

Where a lot of creators go wrong is designing at exactly 1280×720px and stopping there. YouTube displays thumbnails at wildly different sizes depending on context: a 16:9 full-width feature on the homepage, a small 246×138px card in search results, and a tiny strip in the "Up next" sidebar. If your design only reads well at the largest size, you're losing clicks everywhere else. Design at full resolution, but zoom out to 20% and check whether it still communicates.

Instagram Image Sizes

Instagram supports multiple formats, and the algorithm treats them differently. Portrait posts (4:5) take up more screen real estate in the feed, which generally means more engagement.

Format	Dimensions	Aspect ratio
Square post	1080 × 1080 px	1:1
Portrait post	1080 × 1350 px	4:5
Landscape post	1080 × 566 px	1.91:1
Stories / Reels	1080 × 1920 px	9:16
Carousel card	1080 × 1080 px	1:1

Design tip: If you design at 1080×1350px (portrait), Instagram will also display it as a square in grid view — so keep critical content within the central 1080×1080px zone of your portrait canvas.

According to Sprout Social's 2025 benchmark report, portrait posts receive 13% more impressions than square posts on average, largely due to the extra screen space they occupy in the feed.

One subtlety that trips people up: Instagram compresses images more aggressively than most platforms. Even if you upload a pixel-perfect 1080px image, the platform re-encodes it as a JPEG with visible compression artifacts — particularly in gradients, skin tones, and dark backgrounds. To minimise this, export from your design tool at sRGB colour space (not Adobe RGB or Display P3), and keep file sizes around 1–3 MB. Heavier files don't necessarily stay sharper; Instagram re-compresses regardless.

LinkedIn Banner and Post Sizes

LinkedIn is a different beast — professional context means your visuals need to feel polished without screaming "marketing asset."

Format	Dimensions
Profile background (banner)	1584 × 396 px
Company page banner	1128 × 191 px
Shared image post	1200 × 628 px
Shared video cover	1200 × 628 px

Design tip: Your LinkedIn profile photo sits over the bottom-left corner of your banner on desktop and the centre on mobile. Test your banner on both before publishing, and place your name, title, or CTA in the right two-thirds of the canvas.

The 1584×396px personal banner is extremely wide relative to its height — a 4:1 ratio that leaves very little vertical real estate. Avoid large, detailed illustrations; they read as visual noise at that proportion. Solid colours, subtle textures, or a single clean typographic treatment with a brief value statement tend to land better. If you're using an existing landscape image and need to extend it to fill the wide canvas without a hard crop, Playyy's image expand tool can outpaint the edges to match the scene.

Twitter / X Header and Post Sizes

Format	Dimensions
Header / banner	1500 × 500 px
Profile photo	400 × 400 px (displayed as circle)
Shared image	1200 × 675 px (16:9)
Max file size (header)	5 MB

Design tip: The bottom-left of your Twitter header gets covered by your profile photo on desktop. Keep that corner clear. On mobile the overlap shifts — design conservatively and test on both.

Shared images on Twitter/X are cropped to a 16:9 preview in the feed, but tapping through shows the full image. If you upload a portrait or square image, the feed will show a tight centre crop. For link preview cards, the image shown is pulled from your page's Open Graph tags rather than any image you attach — which is a separate problem entirely and worth checking separately if your link previews look broken.

TikTok Cover Image Size

TikTok's cover image (the still that shows in your profile grid) is often an afterthought, but it shapes how your profile looks at a glance.

Format	Dimensions
Video / cover	1080 × 1920 px (9:16)
Profile photo	200 × 200 px minimum

Design tip: TikTok crops your cover to a portrait format in the grid. Centre your key visual and keep text in the middle third of the frame vertically.

If you're building a brand presence on TikTok, treat your cover images as a grid system. Accounts with consistent cover image styling — same colour palette, same text placement, same visual style — tend to see higher profile-to-follow conversion because the profile page communicates identity at a glance. This is worth designing deliberately rather than letting TikTok grab a random frame from your video.

Facebook Image Sizes

Format	Dimensions
Cover photo	820 × 312 px (desktop) / 640 × 360 px (mobile)
Shared link image	1200 × 630 px
Post image	1200 × 630 px
Story	1080 × 1920 px

Facebook's cover photo is a genuinely annoying spec because it displays at different dimensions on desktop versus mobile — and there's no single upload that looks perfect on both without careful planning. The safe zone for content that renders correctly on both is approximately the central 820×312px crop of a 820×360px canvas. Anything in the top and bottom 24px may be cut off on mobile.

For shared posts and link previews, 1200×630px is the reliable standard. Facebook will accept images up to 8MB, but heavily compressed JPEGs at 100–500KB upload and render without visible quality loss in the feed.

Pinterest Image Sizes

Pinterest is a visual search engine as much as a social platform, which means your image dimensions directly affect discoverability — taller pins take up more space in the masonry grid and get more impressions.

Format	Dimensions	Aspect ratio
Standard Pin	1000 × 1500 px	2:3
Long Pin	1000 × 2100 px	1:2.1
Square Pin	1000 × 1000 px	1:1
Story Pin	1080 × 1920 px	9:16
Board cover	800 × 450 px	16:9
Profile photo	165 × 165 px	1:1

Design tip: The 2:3 ratio (1000×1500px) is Pinterest's recommended standard and the safest choice. Pinterest caps displayed aspect ratios at 1:2.1 in the feed — anything taller gets cropped, so "long pins" beyond that threshold are counterproductive. For static image pins, design text and CTA elements in the lower half of the canvas; the top of a pin often gets cropped in grid view on smaller screens.

Pinterest compresses images to WebP on delivery, so uploading a high-quality JPG or PNG at 1–3 MB is sufficient. Very high-contrast or highly detailed images tend to hold up well through Pinterest's compression pipeline compared to gradients or subtle texture work, which can look muddy after re-encoding.

Snapchat Image Sizes

Snapchat is a full-screen vertical platform — every format is 9:16 with no exceptions, and the interface overlays are significant.

Format	Dimensions	Notes
Snap / Story	1080 × 1920 px	9:16 full screen
Spotlight	1080 × 1920 px	9:16, same as Story
Ad / Commercials	1080 × 1920 px	9:16, 3–180 seconds

Design tip: Snapchat overlays username, tap-to-reply UI, and other interface elements at the top and bottom of the screen. Keep your key visuals and any text within the central safe zone: roughly 1080×1420px, centred vertically, leaving about 250px of breathing room at the top and 250px at the bottom. Anything outside that zone risks being obscured by the platform UI.

Snapchat's audience skews younger and expects native-feeling content — overly polished, studio-looking visuals can underperform compared to content that mimics the visual language of user-generated snaps. That said, for ads and brand content, clear product visibility and a readable call to action matter more than looking raw.

How to Design for Every Platform Without Rebuilding Each Visual

More than 80% of social media content is consumed on mobile devices, yet most designers preview their assets on desktop. A LinkedIn banner that reads perfectly in a browser may have its key text partially obscured by the profile photo on a phone. Building to mobile-first safe zones — and testing every asset on a real device before publishing — is the single most skipped step in social media asset production.

The common mistake is designing a YouTube thumbnail, then starting over for Instagram, then starting over again for LinkedIn. That's three times the work for the same campaign.

A smarter approach: design at your largest required canvas (usually 1280×720px for landscape or 1080×1920px for vertical), then use an AI design tool to resize and adapt it for each platform's spec without losing the visual intent. Playyy's AI image editor lets you resize a canvas and regenerate background areas to fill the new dimensions — so a YouTube thumbnail can become an Instagram story without manual cropping or awkward letterboxing.

In practice, this cuts visual asset production time for a single campaign from 3–4 hours to under 45 minutes.

Understand aspect ratios, not just pixel dimensions. Pixel dimensions are what platforms specify, but aspect ratios are what you actually design to. The key ratios to internalise are 16:9 (landscape: YouTube, Twitter, Facebook post), 1:1 (square: Instagram, LinkedIn post), 4:5 (portrait feed: Instagram), and 9:16 (vertical full-screen: Stories, Reels, TikTok, Snapchat). If you build design templates at these four aspect ratios, you cover every major platform — it's the pixel dimensions that vary, not the underlying proportions.

File size limits matter, but not the way most people think. Platforms don't reward larger files with better quality — they re-compress everything on their own terms. What matters is uploading above the minimum quality threshold so the platform's compression starts from a clean source. For most platforms, a 1–3 MB JPG at sRGB is that threshold. Uploading a 15 MB PNG doesn't give you a sharper image; it just makes your upload slower.

Colour space affects how images look after upload. This is the spec detail almost nobody checks. Most platforms display images in sRGB, which is the standard web colour space. If you export from a design tool using a wide-gamut colour profile (Adobe RGB, DCI-P3, Display P3), the colours will appear washed out or shifted when the platform converts them on display. Always export social media assets as sRGB. In Figma, this is the default. In Photoshop, it requires explicitly choosing "Convert to sRGB" on export. If your brand colours look wrong after uploading despite using the correct dimensions, colour space is almost always the culprit.

Test on mobile before publishing. More than 80% of social media consumption happens on mobile, but most designers preview on desktop. A LinkedIn banner that looks great in a browser may have its key text hidden behind the profile photo on a phone screen. A Twitter header CTA that reads clearly at full width may be unreadable at 375px. Build a checklist: before any asset goes live, open it on your phone and confirm it communicates what you intended.

Common Mistakes That Get Your Images Cropped

Even with the right dimensions, images get cropped or visually broken in ways that are entirely avoidable.

1. Putting key content at the edges. Every platform has a safe zone — the region guaranteed to be visible regardless of screen size or UI overlays. The edges outside that zone are at risk. Profile photos, navigation UI, and interface chrome all eat into your canvas. Design with a mental inset of about 10% on all sides for any content that matters: headlines, faces, logos, CTAs.

2. Designing landscape when the platform prefers portrait. For Instagram, Facebook Stories, and TikTok, the feed is vertical. Uploading a landscape image (say, a 1920×1080px banner) forces the platform to show a letterboxed or tightly cropped version. If you're repurposing a horizontal asset for a vertical format, don't just upload it — resize and recompose. Playyy's image expand tool can extend the background of a landscape image to fill a portrait canvas without distorting the subject.

3. Not accounting for profile photo overlap. LinkedIn, Twitter/X, and Facebook all place the profile photo over the banner in the bottom-left or bottom-centre area. This is one of the most common banner design mistakes: a logo or tagline gets half-covered. Map out where the profile photo lands on both desktop and mobile before finalising your layout.

4. Ignoring the grid view crop. On Instagram, your portrait post appears full-size in the feed but is cropped to a 1:1 square in your profile grid. If the most important element of your design is at the top or bottom, it will disappear in grid view. The same issue affects TikTok cover images. Design so that the central square crop of any portrait image still communicates the core message.

5. Using PNG for everything. PNGs are great for graphics with transparency, logos, and images with solid colours or hard edges. But for photographic content, PNG files are much larger than equivalent JPEGs — and platforms that enforce file size limits (YouTube's 2 MB thumbnail limit is the most punishing) will reject oversized PNGs when a compressed JPEG at the same dimensions would be fine. Use JPEG for photos, PNG for graphics.

Platform-Specific Design Tips That Actually Matter

Compression artifacts are platform-dependent. YouTube is more aggressive with thumbnail compression than Instagram; Instagram is more aggressive than LinkedIn. If you're seeing JPEG blocking artifacts in uploaded images — those blocky squares that appear in gradients and dark areas — the fix isn't to upload a larger file, it's to reduce large flat areas of a single colour (which compress poorly) and increase contrast slightly before exporting. This gives the compression algorithm more to work with.

Safe zones differ between desktop and mobile. Every platform has published safe zone specs, but the practical safe zone — the area you can guarantee will be visible on a random device in a random app version — is more conservative than the official specs. For Stories and Reels (1080×1920px), the platform-published safe zone is typically 1080×1420px (250px top/bottom buffer). In practice, adding an extra 50px of margin on all sides is worth it, because some devices add OS-level overlays (notches, dynamic islands, gesture bars) that the platform's specs don't account for.

Mobile previews compress more than desktop previews. When Instagram or LinkedIn serves an image on a low-bandwidth mobile connection, it may serve a lower-resolution version than what you uploaded. This is invisible when you check your post on a fast Wi-Fi connection but visible to a portion of your audience. The best defence: make sure your design reads clearly even if it were displayed at half the resolution. High contrast, large text, and clean composition matter more for mobile reach than pixel-perfect detail.

Background removal changes compression behaviour. If you use background remover to isolate a subject and then place it on a flat coloured background, be aware that flat backgrounds compress very poorly as JPEGs. A solid dark background with a subject in the foreground will produce visible JPEG blocking around the subject edges after platform compression. Save images with isolated subjects on flat backgrounds as PNGs where file size limits allow, or add a subtle texture or gradient to the background to give the JPEG algorithm something to work with.

LinkedIn posts render differently in external shares. When a LinkedIn post is shared externally (e.g. someone copies the URL), the Open Graph image is what appears in the preview — not the image you attached to the post. These are two separate image slots with different dimension requirements. If you care about how your LinkedIn content looks when shared outside the platform, set OG images separately at 1200×628px.

Wrapping Up

Platform specs change more often than most people realise — usually without announcement. What was correct 18 months ago may be subtly wrong today. The safest practice is to bookmark a maintained reference (this one is updated as platforms change), design to the aspect ratios rather than memorising pixel numbers, and test every asset on mobile before publishing.
