| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Square post | 1:1 | Safe universal format, but takes less feed space than vertical; portrait usually wins more reach. | |
| Portrait post | 4:5 | Default vertical and best all-round feed size; the profile grid crops a thin top and bottom strip to 3:4, so keep faces and text centered. | |
| Landscape post | 1.91:1 | Smallest in-feed footprint; only use for wide photos since vertical formats out-perform it on reach. | |
| Story | 9:16 | Keep text and logos out of the top and bottom ~250px so the profile bar and UI do not cover them. | |
| Reel | 9:16 | Full-screen vertical; keep captions in the central safe zone away from the right-side icons and bottom caption bar. | |
| Reel cover | 9:16 | Upload at full reel size but design the key visual inside the central ~1080 × 1420 area that shows in the grid crop. | |
| Profile photo | 1:1 | Displays as a small circle (~110px), so use a centered high-contrast mark and avoid edge detail. | |
| Carousel | 4:5 | All slides inherit the first slide's ratio; 4:5 maximizes space, keep ~50px edge padding, up to 20 slides. |
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Shared / link post (OG image) | 1.91:1 | Set via the og:image tag; keep the headline and faces centered (min 600 × 315) to avoid link-preview cropping. | |
| Square post | 1:1 | Strong mobile-feed footprint; Facebook also supports 4:5 (1080 × 1350) for more vertical space. | |
| Story | 9:16 | Keep key content inside the central 1080 × 1680 safe zone so top and bottom UI do not cover it. | |
| Cover photo | 2.7:1 | Displays 820 × 312 on desktop but crops to roughly 640 × 360 on mobile, so keep critical elements centered. | |
| Profile photo | 1:1 | Circle-cropped, showing ~176px desktop and ~196px mobile; center the subject and avoid corner detail. | |
| Event cover | 1.91:1 | Keep the bottom third clear since Facebook overlays the event title and date there. |
X (Twitter)
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| In-stream post image | 16:9 | Displays uncropped in the timeline; square (1080 × 1080) and portrait (1080 × 1350) also work, max 5MB per image. | |
| Header / banner | 3:1 | Up to ~60px can be trimmed from the top and bottom depending on screen, so keep key elements centered. | |
| Profile photo | 1:1 | Cropped to a circle so center your subject; upload square, max 2MB. |
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Shared post / link image | 1.91:1 | Best size for a shared article or link preview; an image under 200px wide shows as a small left-side thumbnail instead. | |
| Square post | 1:1 | Strongest single-image feed format; takes more vertical space on mobile than landscape, max 5MB. | |
| Personal profile banner | 4:1 | Mobile crops the banner differently than desktop, so keep text and logos centered and away from the edges. | |
| Company page cover | 6:1 | Current official spec (the legacy 1128 × 191 is the same 6:1 ratio but outdated); keep key details out of the lower-right corner. | |
| Profile photo | 1:1 | Cropped to a circle; minimum 268 × 268, max 8MB, same recommended size for a company logo. |
TikTok
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Video / cover | 9:16 | The cover and thumbnail use the same full-screen 9:16 frame as the video; keep the subject centered to avoid UI overlays. | |
| Profile photo | 1:1 | Displays as a circle; 200 × 200 is the minimum, so upload 400 × 400 or larger for a crisp retina display. |
YouTube
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Thumbnail | 16:9 | Minimum 640px wide; keep the file under the 2MB upload limit in JPG, PNG or GIF. | |
| Channel banner | 16:9 | Crops per device, so keep logo and text inside the 1546 × 423 center safe area visible on all screens; max 6MB. | |
| Profile photo | 1:1 | Auto-cropped to a circle; must read clearly down to ~40px in comments, max 4MB. | |
| Shorts | 9:16 | Vertical full-screen frame; keep captions clear of the bottom-right action rail and bottom UI. |
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Standard pin | 2:3 | 2:3 is the best-performing pin ratio; taller pins get cropped in the feed. | |
| Square pin | 1:1 | Use 1:1 for product or collection pins; vertical 2:3 still outperforms it on reach. | |
| Idea pin (vertical) | 9:16 | Idea Pins merged into the unified Pin format; build vertical multi-page content at 9:16 in the standard Pin builder. | |
| Profile photo | 1:1 | Upload square; displays as a small circle crop, so keep logos centered. |
Threads
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Post image (portrait) | 4:5 | 4:5 fills the most vertical feed space; Threads supports taller crops but 1080 × 1350 is the safe recommended upload. | |
| Square post | 1:1 | Clean 1:1 option; Threads displays it uncropped in the feed. | |
| Profile photo | 1:1 | Threads pulls your Instagram profile photo; upload at least 320 × 320, displays as a circle. |
Bluesky
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Post image | 16:9 | The server compresses each image under 1MB and caps the longest side at 2000px, so 1:1 or portrait crops work equally well. | |
| Banner | 3:1 | Keep text centered and clear of the lower-left, where the circular avatar overlaps and mobile crops the sides tighter. | |
| Avatar | 1:1 | Displayed as a circle, so center the subject and avoid important detail in the corners. |
Mastodon
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Post image | 1:1 | Default instances accept up to 16MB and downscale anything above 8.3MP, so a 1280px upload posts without recompression; per-instance limits vary. | |
| Header | 3:1 | Uploads up to 2MB are resized to exactly 1500 × 500; the avatar overlaps the lower-left, so keep key content centered. | |
| Avatar | 1:1 | Resized to 400 × 400 (max 2MB); rendered as a rounded-square by default, though some instance themes crop it to a circle. |

No credit card required - 500 free DMs/monthThe 2026 social media image size guide
Every platform crops, compresses and displays images differently, and the specs drift every year. Upload the wrong dimensions and your post gets letterboxed, your text gets cut off, or your image turns blurry. This cheat sheet gives you the exact pixel size and aspect ratio for every common format across ten platforms, kept current for 2026. Click any size to copy it.
Vertical wins almost everywhere
Feeds are mobile-first, so 4:5 (1080 × 1350) for posts and 9:16 (1080 × 1920) for stories, reels and shorts take the most screen space and usually earn the most reach. Square and landscape still have their place, but default to vertical.
Design for the safe zone, not just the canvas
Stories, reels and banners have UI overlays and per-device crops. Keep text, faces and logos in the centre and away from the top, bottom and corners so nothing important gets covered or trimmed.
Match the ratio, hit the size, watch the file limit
Wrong ratio means cropping. Too small means upscaling and blur. Over the file-size cap means recompression. Upload at the exact size here, and most blurry-or-cropped problems disappear.
The aspect ratios that matter
How creators use this guide
Export once, post everywhere
Design your Reel at 1080 × 1920 and your feed post at 1080 × 1350, and the same shoot covers Instagram, TikTok, Threads and Shorts without re-cropping.
Stop the blurry-cover tickets
Hand this cheat sheet to the team so every cover, banner and OG image goes out at the right size the first time. Copy the dimension straight into your design tool.
Set the right Open Graph image
Use 1200 × 630 for og:image so your links unfurl with a clean preview card on Facebook, LinkedIn, X and Slack instead of a tiny thumbnail.
Quick rules that save reposts
- Upload at the recommended size or larger, never smaller. Platforms downscale cleanly but upscaling looks soft.
- Profile photos are almost always shown as a circle. Centre your mark and leave breathing room around it.
- Export as PNG for graphics and text, JPG for photos. Watch each platform's file-size cap to avoid recompression.
- When in doubt, 1080 × 1350 (4:5) for a post and 1080 × 1920 (9:16) for everything full-screen covers most platforms.
The right image size gets the view. An automated DM is what turns that view into a lead.

Social media image sizes: questions
What is the best Instagram post size in 2026?
1080 × 1350 pixels (a 4:5 portrait) is the best all-round Instagram feed size in 2026 — it takes the most vertical space, which usually means more reach than a 1:1 square. Stories and Reels use 1080 × 1920 (9:16). The profile grid crops portrait posts to roughly 3:4, so keep faces and text away from the very top and bottom.
What is the ideal Open Graph (link preview) image size?
1200 × 630 pixels (1.91:1). It is the size Facebook, LinkedIn and most link unfurlers use for the preview card when your page is shared. Keep the headline and any faces centered so nothing important is cropped on smaller previews.
What aspect ratio should I use for Reels, Stories and TikTok?
9:16 vertical at 1080 × 1920 pixels, for Instagram Reels and Stories, TikTok, YouTube Shorts and Facebook Stories. Keep captions and logos inside the central safe zone so the platform's on-screen buttons do not cover them.
Why does my image look blurry or cropped after uploading?
Blurry usually means the image was smaller than the recommended size and the platform upscaled it, or it was over the file-size limit and got recompressed. Cropped means the aspect ratio did not match, so the platform trimmed the edges. Upload at the exact dimensions in this guide and keep key content centered.
How often do these sizes change?
Core sizes like 1080 × 1080, 1080 × 1350 and 1080 × 1920 have been stable for years. Banners, covers and a few platform-specific specs change more often, which is why this guide is dated 2026 and reviewed for the current crop behaviour of each app.
Is this image size guide free?
Yes. It is completely free, needs no signup and covers every major platform. You can copy any dimension to your clipboard in one click.
