Social Media Image Sizes 2026: Every Platform in One Place

Every time I prepare assets for a new project, I end up searching "Instagram image size 2026" or "LinkedIn cover photo dimensions" because I can never remember them all. And half the results are outdated articles from 2023 still recommending sizes that have since changed.

So I put together this reference — updated for 2026 — covering every platform I actually use. Bookmark it. You'll need it again.

When I was preparing launch assets for a restaurant client app through Brenqo, I shipped a LinkedIn company banner built from a cropped landscape photo instead of designing for 1128 × 191 — everything important sat in the strips that get clipped on desktop. It looked stretched and awkward for nearly two weeks before someone on the sales team flagged it during a demo.

Why Image Sizes Matter More Than You Think

Uploading the wrong size doesn't just look bad — it actively hurts you:

• Cropped wrong: Platform crops your image automatically, cutting off your logo or text
• Stretched or squished: Low quality appearance, looks unprofessional
• Pixelated: Uploading too small and platform stretches it up
• Algorithm penalty: Some platforms deprioritize posts with low-quality images

Getting the dimensions right takes 2 extra minutes and makes everything look intentional.

Instagram

Instagram is the most size-sensitive platform. It supports multiple formats depending on where the image appears.

Feed Posts

Which to use: Portrait (4:5) takes up the most screen space in the feed — more visibility, more engagement. Use it unless your content is specifically designed for square or landscape.

Stories & Reels

Always design Stories with safe zones — keep important content 250px from the top and bottom edges to avoid being covered by UI elements.

Profile Picture

• Size: 320 × 320 px minimum
• Displays as: Circle crop — keep your logo/face centered

A square wordmark squeezed into 320 × 320 without padding will kiss the circular edge and look chopped. I learnt that the hard way on a SaaS client's profile — we added a tighter mark version with breathing room centered in the circle, and it finally read cleanly at feed scale.

Twitter / X

Twitter/X changed its image handling multiple times. Here are the current specs:

Feed Images

Important: Twitter crops images in the feed to a 16:9 preview. The full image shows when tapped. Keep your most important content in the center 2/3 of the image.

Profile & Header

The header gets heavily cropped on mobile. Design it so the center matters most — don't put text at the very edges.

Link Preview (OG Image)

• Size: 1200 × 630 px
• This is the image that shows when you share a URL
• Set this in your <meta property="og:image"> tag

For SnapResizer's own Next.js app, OG images live in metadata.openGraph and twitter alongside metadataBase. Once I tweaked a landing description but forgot openGraph.images still pointed at a square asset — link previews picked up awkward padding in Slack until I exported a crisp 1200 × 630 and cleared the crawler cache.

LinkedIn

LinkedIn is where professional content lives, so image quality and sizing matters a lot here.

Feed Posts

Landscape is the default and most common. If you're sharing a blog post link, LinkedIn pulls the OG image — make sure your site's OG image is 1200 × 627 px.

Profile & Company Page

The company cover image is extremely wide and short — design specifically for this ratio, don't just stretch a regular image.

Article Cover Image

• Size: 1200 × 644 px
• Used when you publish a LinkedIn article (not a regular post)

Facebook

Facebook supports the widest variety of content types, each with different requirements.

Feed Posts

Profile & Cover

Cover photo tip: Design at 820 × 312 px but keep important content within the center — mobile crops it to 640 × 360 px, so the sides get cut.

Facebook Stories

• Size: 1080 × 1920 px (same as Instagram Stories)

Event Cover

• Size: 1920 × 1080 px
• One of the few places Facebook recommends landscape format

YouTube

YouTube is primarily video, but the image assets matter for channel branding and discoverability.

Thumbnails

• Size: 1280 × 720 px (minimum), 1920 × 1080 px (recommended)
• Format: JPG, GIF, PNG, or WebP
• Max file size: 2MB
• Aspect ratio: 16:9

Thumbnails are arguably the most important image asset on YouTube — they directly determine click-through rate. Design them at 1920 × 1080 px even though 1280 × 720 px is accepted.

I watch a ton of coding walkthroughs, and thumbnails with a readable title treatment plus a human face consistently outperform flat IDE screenshots — I mirror that when exporting channel art now: crop tight, crank contrast, assume half the viewers are on their phone first.

Channel Art

The channel banner has a complex safe zone — only the center 1546 × 423 px is guaranteed to show on all devices. Design your important content (name, logo, tagline) within that area.

TikTok

TikTok is almost entirely vertical video, but profile images matter for brand recognition.

Videos

• Size: 1080 × 1920 px (9:16 vertical)
• Safe zone: Keep text and faces away from bottom 20% (overlaid by UI)

Profile Photo

• Size: 200 × 200 px minimum
• Displays as a circle

TikTok Ads (if running paid promotion)

Pinterest

Pinterest is built around images, so quality and sizing directly impacts reach.

Pins

2:3 portrait is the Pinterest sweet spot. Longer pins get cut off in feeds. Stick to 1000 × 1500 px for maximum visibility.

Profile Photo

• Size: 165 × 165 px

WhatsApp

Often overlooked, but if you're sharing assets via WhatsApp (especially for client work or business):

WhatsApp compresses images heavily. If you need to share a high-quality image, send it as a document (tap the attachment icon → Document) instead of a photo — it skips the compression.

I use that document trick anytime a founder wants to approve hero photography or UI exports from Figma snapshots — JPEGs routed as photos come back muddy; the DOC path keeps pixels intact enough for Slack forwards later.

How to Resize to These Dimensions Quickly

The fastest workflow I use:

1. Design your asset at the largest size needed (usually 1920×1080 or 1080×1920)
2. Export as PNG
3. Open SnapResizer
4. Drop the file in, enter the target dimensions
5. Download — done in under 30 seconds

No Photoshop. No upload queue. Your file never leaves your browser.

For batch work (resizing the same image to 5 different platform sizes), SnapResizer's batch resize handles all of them at once.

One Last Tip

These sizes are correct as of May 2026, but social platforms update their specs occasionally — usually after major app redesigns. If something looks off after uploading, always double-check the platform's own help documentation before spending time redesigning.
