For anyone producing images for several networks who wants one page of current, sourced numbers instead of a chart that may be years old.
Social media image sizes, checked against each platform's own docs.
Most size charts copy each other, so old numbers live on long after a platform changes them. This reference takes each size from the platform's own help center, ads guide or developer docs, as checked in October 2026, and says where a platform does not publish a number. Each platform has its own table, followed by the MockupX canvas that matches. Sizes change; when a table and the platform's composer disagree, trust the composer.

Instagram image sizes
Instagram's help center says photos are kept at their original resolution when they are 320 to 1080 pixels wide with an aspect ratio between 1.91:1 and 3:4; wider images are resized to 1080 pixels, and other ratios are cropped. Carousels hold up to 20 items with one orientation for the whole post. Story specs come from Meta's Ads Guide, since Instagram's help center does not list a Story pixel size. The Instagram Story and carousel pages on this site cover safe zones and sequencing.
| Format | Ratio | Size | MockupX canvas |
|---|---|---|---|
| Feed, portrait | 4:5 | 1080 × 1350 px | Portrait preset |
| Feed, tallest | 3:4 | 1080 × 1440 px | Custom size |
| Feed, square | 1:1 | 1080 × 1080 px | Square preset |

Facebook and Meta ad sizes
Meta's Ads Guide gives the ad specs below; the Facebook Help Center gives Page sizes. For Stories and Reels ads, Meta recommends leaving about 14% at the top, 35% at the bottom and 6% on each side free of text and logos. The Facebook ad page on this site has the full placement table and text limits.
| Format | Ratio | Size | MockupX canvas |

LinkedIn image sizes
LinkedIn's help center covers organic posts and documents; the LinkedIn Marketing Solutions ads guide covers ads. The swipeable carousel most people post is a document (PDF recommended) up to 100 MB and 300 pages. The LinkedIn carousel page on this site explains how to build those pages and assemble the PDF.
| Format | Ratio | Size | MockupX canvas |
|---|---|---|---|
| Image post | Any | At least 552 × 276 px; 1080 px wide recommended; up to 20 photos | Square or Portrait preset |

X (Twitter) image sizes
X's developer documentation lists formats, file sizes and how many images a post can carry, but does not publish a recommended in-feed pixel size. The canvases below are working sizes; the X post page on this site covers crops and multi-image layouts.
| Item | Limit or size | Source | MockupX canvas |
|---|---|---|---|
| Formats | JPG, PNG, GIF, WebP | docs.x.com | - |
| Image file size | 5 MB maximum; GIF 15 MB | docs.x.com | - |
| Media per post | 4 photos, or 1 GIF, or 1 video | docs.x.com | - |

| Header | 3:1, 1500 × 500 px | Working canvas; check in the profile editor | X cover preset |
YouTube thumbnail sizes
YouTube's help center now recommends 3840 × 2160 thumbnails rather than the long-quoted 1280 × 720, which remains valid because it is 16:9 and above the 640-pixel minimum. Custom thumbnails require a verified account. The YouTube thumbnail page on this site covers layout and the small-size test.
| Format | Ratio | Size | MockupX canvas |
|---|---|---|---|
| Video thumbnail | 16:9 | 3840 × 2160 px recommended, 640 px minimum width | YouTube preset (1280 × 720) or custom 3840 × 2160 |
| Shorts thumbnail | 9:16 | 2160 × 3840 px recommended, 640 px minimum height | Story preset or custom 2160 × 3840 |
| File limits | - | JPG or PNG; 2 MB on mobile, 50 MB on desktop | Export JPEG for large thumbnails |
Pinterest image sizes
Pinterest recommends 2:3 at 1000 × 1500 pixels and warns that taller Pins may be cut off. Its Pin specs page lists a safe zone of 270 px top, 65 px left, 195 px right and 790 px bottom alongside the full-screen format. The Pinterest Pin page on this site covers layout and reusable templates.
| Format | Ratio | Size | MockupX canvas |
|---|---|---|---|
| Standard Pin | 2:3 | 1000 × 1500 px; 20 MB on web | Custom 1000 × 1500 |
| Full-screen video Pin | 9:16 | 1080 × 1920 px | Story preset |
| Carousel ad | 1:1 or 2:3 | 2 to 5 images, 20 MB each | Square preset or custom 1000 × 1500 |
| Pin title | - | 100 characters; first 40 most likely to show | - |
Product Hunt and app store sizes
Product Hunt is not a social network, but its gallery is where many software launches are judged, and its help center publishes exact sizes. App store screenshots follow Apple's and Google's own rules; this site covers them on separate pages, linked below.
| Format | Size | Notes | MockupX canvas |
|---|---|---|---|
| Product Hunt thumbnail | 240 × 240 px recommended, square | Under 3 MB; GIFs animate only on hover | Custom square, 320 px or larger |
| Product Hunt gallery | 1270 × 760 px recommended | At least 2 images before the gallery shows | Custom 1270 × 760 |
| App Store screenshots | Set by Apple per device | See the App Store screenshot sizes guide | App Store presets |
| Google Play feature graphic | 1024 × 500 px | See the feature graphic generator | Feature graphic preset |
Four shapes cover most of it
Across all of these tables, four shapes do most of the work: 1:1 square, 4:5 portrait, 9:16 vertical and 16:9 wide. A campaign that builds those four from the same screenshot, headline and background covers Instagram, Facebook, LinkedIn, X and YouTube with only a few specialized additions (a 2:3 Pin, a 1270 × 760 Product Hunt gallery image, a document for LinkedIn).
Do not simply crop one master image into all four. A layout that works at 4:5 usually needs its headline moved for 9:16 and its screenshot cropped tighter for 1:1. Keep the screenshot, headline, background and frame the same, and recompose each shape. Track each variant's destination, size, owner and approval date in a simple sheet so stale versions do not get posted.
| MockupX canvas | Size | Fits |
|---|---|---|
| Square | 1080 × 1080 | Instagram feed, Meta carousel and Marketplace ads, LinkedIn and X posts, LinkedIn document pages |
| Portrait | 1080 × 1350 | Instagram and Facebook feed, LinkedIn vertical ads (mobile), Instagram carousels |
| Story | 1080 × 1920 | Instagram and Facebook Stories, Reels covers, Shorts thumbnails, full-screen Pins |
| X post | 1600 × 900 | X posts, wide LinkedIn and Facebook posts |
| YouTube thumbnail | 1280 × 720 | YouTube video thumbnails |
| 1200 × 627 | LinkedIn horizontal posts and ads | |
| X cover | 1500 × 500 | X profile header |
| HD | 1920 × 1080 | Slides, landing pages, video title cards |
| Custom | 320 to 6000 px per side | Pins, Product Hunt, Facebook covers, 1440-wide Meta ads, 4K thumbnails |
Produce a multi-platform image set in four steps
Build the four core shapes from one design, then add the platform-specific extras.
- List the placements you actually publish to and look up each one in the tables above.
- Design the 4:5 version first, then recompose the same screenshot, headline and background at 1:1, 9:16 and 16:9.
- Add the specialized sizes you need (a 1000 × 1500 Pin, a 1270 × 760 Product Hunt image, a 3840 × 2160 thumbnail) using custom canvases.
- Export each version, name it with platform and size, and preview it in the platform's composer before publishing.
social media image sizes FAQ
What is the best image size for all social media?
There is no single size. A 1080 × 1080 square is accepted almost everywhere, but 4:5 uses more feed space, 9:16 is needed for Stories and Reels, and 16:9 suits YouTube and wide posts. Build those four from one design.
Where do these image sizes come from?
Each size comes from the platform's own documentation: the Instagram Help Center, Meta Ads Guide and Facebook Help Center, LinkedIn Help and LinkedIn's ads guide, X's developer docs, YouTube Help, Pinterest's help center and business site, and Product Hunt's help center, as checked in October 2026.
Why do different charts give different sizes?
Platforms change their specs, and many charts copy older charts. YouTube now recommends 3840 × 2160 rather than 1280 × 720, and Instagram's help center now lists 3:4 as the tallest feed ratio. Check the platform's own page or composer when in doubt.
What is the Instagram post size?
1080 pixels wide with an aspect ratio between 1.91:1 and 3:4: 1080 × 1350 for 4:5 portrait, 1080 × 1440 for 3:4, 1080 × 1080 for square.
Which sizes does MockupX have built in?
Square 1080 × 1080, Portrait 1080 × 1350, Story 1080 × 1920, X post 1600 × 900, LinkedIn 1200 × 627, YouTube thumbnail 1280 × 720, X cover 1500 × 500, HD 1920 × 1080 and others, plus custom sizes from 320 to 6000 pixels per side.
