imageImageAbout Social Media Specs
Social Media Specs is a free, searchable reference guide that lists the recommended image and video dimensions for 156 format slots across 16 major platforms: Instagram, Facebook, X (Twitter), LinkedIn, Threads, Pinterest, YouTube, TikTok, Twitch, Snapchat, Etsy, Reddit, Spotify, Bluesky, Discord, and Mastodon. Each card shows the format name, media type (Image, Video, or Display), pixel dimensions, and aspect ratio — everything a designer or content creator needs before opening their editor.
Platform requirements differ significantly and change over time. Instagram favors 4:5 vertical posts for maximum feed real estate, while LinkedIn article covers expect a wide 16:9 crop, and Pinterest Standard Pins perform best at 2:3. Getting any of these wrong means the platform crops or compresses your asset, degrading quality and wasting production time. This tool lets you look up the exact spec in seconds rather than hunting through scattered help-center articles.
All 156 specifications are bundled directly into the page. Nothing is fetched from a server at runtime, so lookups are instant, work offline once the page has loaded, and involve zero data upload. There are no accounts, paywalls, or rate limits — just a fast reference you can keep open in a browser tab while you design.
Key Features
156 specs across 16 platforms
Covers every major platform from Instagram and TikTok to Bluesky, Mastodon, and Etsy, with individual cards for feed posts, stories, ads, profile photos, banners, and more.
Search by name, platform, or dimension
Type a format name like "Reels", a platform like "LinkedIn", or a pixel value like "1080x1920" and the list narrows in real time without a page reload.
Filter by platform and media type
Isolate a single platform with the platform dropdown, then narrow further to Images or Videos so you only see the subset relevant to your current project.
Grid and list view modes
Switch between a card grid for visual scanning and a compact table for dense comparison — useful when you need to compare multiple formats side by side.
Aspect ratio shown alongside pixel dimensions
Every card displays both the pixel size and the aspect ratio (e.g., 9:16, 4:5, 1.91:1) so you can confirm crop ratios before resizing, not after.
Instant, offline-ready reference
All data is stored in the page bundle. Once loaded, the tool responds immediately and continues to work without an internet connection.
How to Use

- arrow_circle_right
Preparing assets before a design session
Look up the exact pixel dimensions for every placement — feed post, story, cover photo, ad — before opening Figma or Photoshop, so you create artboards at the correct size from the start.

Auditing a content calendar for spec compliance
When planning a multi-platform campaign, cross-reference each scheduled asset against the spec list to catch mismatches before production, not after a rejection from an ad platform.
- arrow_circle_right
Briefing freelancers or agencies
Share the exact dimensions and aspect ratios with a designer or video editor who may not know your target platforms, reducing back-and-forth and revision cycles.

Diagnosing cropped or compressed uploads
If a published image looks wrong, look up the platform spec to confirm whether you submitted the correct dimensions and aspect ratio, or identify exactly which dimension needs adjustment.

Learning the differences between platforms
Compare how Instagram, LinkedIn, and Pinterest each handle portrait images — all three accept vertical content but at different aspect ratios (4:5 vs 4:5/1.91:1 vs 2:3) — to choose the right crop for cross-posting.
