What are social media specs?
Social media post specs are the recommended dimensions, file types, and limits for images, videos, and other media on each platform.
When you design within specs, your content shows up clearly, loads faster, and feels intentional instead of improvised.
Why post specs matter:
- Look professional: Avoid awkward crops, stretched images, or blurry videos
- Support engagement: Clean, well-formatted posts are easier to stop and interact with
- Stay consistent: Each platform displays content differently – specs help protect your brand's look
- Work with the algorithm: Platforms favour content that loads quickly and displays correctly
- Save time: Design it right the first time and skip last-minute resizing
Think of post specs like the rules of the road for social media. Follow them, and your content flows smoothly. Ignore them, and things can get a little bumpy.

FAQs
What are the media specs for Instagram?
Instagram supports several formats – square, portrait, and landscape images, carousels, Stories, and Reels. Each one has its own recommended dimensions and file limits. Following those specs helps your content look sharp, fill the screen properly, and feel native in the feed.
Do social media specs change often?
Yes. Platforms tweak layouts, feeds, and formats more often than we’d all like. Core dimensions usually stay fairly stable, but it’s a good idea to double-check specs regularly so your content doesn’t fall out of step with platform updates.
What happens if I use the wrong image or video size?
Your post might get cropped, look pixelated, or display oddly – especially on mobile. In some cases, key text or visuals can be cut off entirely, which can hurt engagement and make your brand feel less polished.
Are social media post specs the same for all platforms?
Nope. Every platform plays by its own rules. TikTok is built for vertical video, LinkedIn leans into documents and landscape visuals, and Instagram offers a mix of feed and Story formats – all with different specs.
What image format is best for social media posts?
JPEG and PNG are your safest bets across platforms. JPEGs work well for photos, while PNGs are better for graphics, text, and logos that need crisp edges.
Are social media specs different for mobile and desktop?
Yes. Most platforms are mobile-first, which means specs are designed with smaller screens in mind. Using the recommended sizes helps your content display cleanly on both mobile and desktop – without surprise crops.
Best practices across all platforms
No matter where you’re posting, these best practices help your content feel intentional and perform better:
- Design mobile-first: Most of your community will see your posts on their phones
- Add captions to every video: Autoplay is muted, and captions support accessibility
- Keep branding consistent: Fonts, colours, and visual style should feel cohesive across formats
- Use carousels with purpose: Each slide should move the story forward
- Test and learn: Track performance and adjust based on what actually works
- Do a final human review: A last pass keeps your tone, authenticity, and brand voice intact
Using the right post sizes in 2026 helps your content look professional, feel polished, and show up the way you intended across platforms.
