Social Media Image Sizes — 2026 Cheat Sheet
Every platform dimension in one table: Instagram, Facebook, X, LinkedIn, YouTube, TikTok, Pinterest and Threads.
No signup, no trackingEvery social platform has its own pixel dimensions, and uploading the wrong size means a blurry crop or wasted whitespace. This is the lookup table: one page with every dimension you actually need, organized by platform.
All dimensions below are in pixels (width × height). Where a platform accepts a range, the recommended size is listed first. Sizes were last verified in August 2026 — platforms update periodically, so check back if something looks off.
Instagram image sizes
Instagram supports square, portrait and landscape posts. Portrait (4:5) gets the most screen real estate in the feed and is the recommended default for engagement.
| Image type | Dimensions (px) | Aspect ratio | Notes |
|---|---|---|---|
| Profile photo | 320 × 320 | 1:1 | Displays at 110 × 110; upload at least 320 px for sharpness on Retina screens. |
| Square post | 1080 × 1080 | 1:1 | The classic Instagram format. Safe for every placement. |
| Portrait post | 1080 × 1350 | 4:5 | Takes the most feed space — recommended for engagement. |
| Landscape post | 1080 × 566 | 1.91:1 | Loses vertical space in the feed; use for panoramic shots only. |
| Story / Reel | 1080 × 1920 | 9:16 | Full-screen vertical. Keep text and faces away from the top 250 px and bottom 400 px (UI overlays). |
| Reel cover thumbnail | 1080 × 1920 | 9:16 | Displays cropped to 1:1 on profile grid; center the subject. |
| Carousel | 1080 × 1080 or 1080 × 1350 | 1:1 or 4:5 | All slides in a carousel must share the same aspect ratio. |
Facebook image sizes
Facebook aggressively compresses uploads, so starting with a sharp, correctly sized file matters more here than on most platforms. JPG at 80–85% quality or PNG for graphics with text.
| Image type | Dimensions (px) | Aspect ratio | Notes |
|---|---|---|---|
| Profile photo | 170 × 170 | 1:1 | Displays at 170 px on desktop, 128 px on mobile. Crops to a circle. |
| Cover photo | 820 × 312 | ~2.63:1 | Desktop display; mobile crops to roughly 640 × 360. Keep key content centered. |
| Shared image (post) | 1200 × 630 | 1.91:1 | The standard for feed posts and shared links. Also used for og:image. |
| Event cover | 1200 × 628 | 1.91:1 | Nearly identical to post image; avoid text near edges. |
| Story | 1080 × 1920 | 9:16 | Same as Instagram Stories. Top and bottom 14% are covered by UI. |
| Group cover | 1640 × 856 | 1.91:1 | Wider than a page cover. Displays differently on desktop and mobile. |
X (Twitter) image sizes
X crops images aggressively in the timeline. A 16:9 or 2:1 ratio avoids most unexpected crops; a single image in a tweet can display uncropped if it falls within the 2:1 to 3:4 range.
| Image type | Dimensions (px) | Aspect ratio | Notes |
|---|---|---|---|
| Profile photo | 400 × 400 | 1:1 | Displays at 200 px circle in the feed, larger on the profile page. |
| Header / banner | 1500 × 500 | 3:1 | Appears behind the profile photo; bottom ~70 px are obscured by the avatar. |
| Single image in tweet | 1600 × 900 | 16:9 | Up to 5 MB for photos, 15 MB for GIFs. JPG or PNG. |
| Two images in tweet | 700 × 800 each | 7:8 | Side by side; each image is cropped to a tall rectangle. |
| Summary card (link) | 800 × 418 | 1.91:1 | Set via twitter:image meta tag. Minimum 300 × 157. |
| Summary card (large image) | 800 × 418 | 1.91:1 | Same dimensions; uses twitter:card = summary_large_image. |
LinkedIn image sizes
LinkedIn supports both personal profiles and company pages, each with different cover dimensions. Post images display well at 1.91:1, the same ratio used by Facebook and X for link previews.
| Image type | Dimensions (px) | Aspect ratio | Notes |
|---|---|---|---|
| Profile photo | 400 × 400 | 1:1 | Minimum 200 × 200. Displays as a circle. |
| Personal cover | 1584 × 396 | 4:1 | The background image on a personal profile. |
| Company page cover | 1128 × 191 | ~5.9:1 | Narrower than personal covers — do not reuse the same image. |
| Post image (landscape) | 1200 × 627 | 1.91:1 | Recommended for shared images and articles. Also used for og:image. |
| Post image (square) | 1200 × 1200 | 1:1 | Square posts take more feed space on mobile. |
| Article cover | 1200 × 644 | ~1.86:1 | The header image for LinkedIn articles / newsletters. |
YouTube image sizes
YouTube thumbnails are arguably the single highest-leverage image on any platform — they directly determine click-through rate. Upload the full 1280 × 720 even if the video is short.
| Image type | Dimensions (px) | Aspect ratio | Notes |
|---|---|---|---|
| Video thumbnail | 1280 × 720 | 16:9 | Minimum 640 × 360. Must be under 2 MB. JPG, PNG, or GIF (static). |
| Channel profile | 800 × 800 | 1:1 | Displays as a circle at various sizes across YouTube. |
| Channel banner | 2560 × 1440 | 16:9 | Safe area for all devices: the center 1546 × 423 px. Text outside this zone gets cropped on mobile or TV. |
| Video watermark | 150 × 150 | 1:1 | The subscribe-button branding overlay. Transparent PNG recommended. |
TikTok image sizes
TikTok is video-first, but the profile photo and video cover thumbnail still matter for brand recognition and search appearance.
| Image type | Dimensions (px) | Aspect ratio | Notes |
|---|---|---|---|
| Profile photo | 200 × 200 | 1:1 | Small display size — use a simple, high-contrast image. |
| Video | 1080 × 1920 | 9:16 | Full vertical. Same dimensions as Instagram Reels and Stories. |
| Video cover | 1080 × 1920 | 9:16 | The frame shown on your profile grid. Pick a frame with a clear subject. |
Pinterest image sizes
Pinterest is a vertical-scroll platform, so tall images dominate. The sweet spot is 2:3 — tall enough to stand out, short enough that Pinterest does not truncate it in the feed.
| Image type | Dimensions (px) | Aspect ratio | Notes |
|---|---|---|---|
| Standard pin | 1000 × 1500 | 2:3 | The recommended default. Taller pins (over 2:3) are truncated in the feed. |
| Square pin | 1000 × 1000 | 1:1 | Works but wastes vertical space — prefer 2:3 for engagement. |
| Profile photo | 165 × 165 | 1:1 | Very small display; keep it simple. |
| Board cover | 600 × 600 | 1:1 | Displays as a square thumbnail for the board. |
Threads image sizes
Threads uses the same image infrastructure as Instagram. Portrait (4:5) works well; the profile photo is pulled directly from your linked Instagram account.
| Image type | Dimensions (px) | Aspect ratio | Notes |
|---|---|---|---|
| Post image (portrait) | 1080 × 1350 | 4:5 | Recommended for maximum feed presence. |
| Post image (square) | 1080 × 1080 | 1:1 | Safe fallback — works everywhere. |
| Post image (landscape) | 1080 × 566 | 1.91:1 | Supported but loses vertical real estate. |
| Profile photo | 320 × 320 | 1:1 | Synced from Instagram — cannot be set separately. |
Quick format tips
- JPG for photos, PNG for graphics with text or transparency, WebP for both if the platform accepts it (most do in 2026). AVIF support is growing but not universal.
- Always export at the exact pixel dimensions listed above — do not rely on the platform to downscale cleanly. Upload a 4000 × 2250 thumbnail and YouTube will recompress it harder than a 1280 × 720 one.
- sRGB is the only safe color space. Upload an image in Display P3 or Adobe RGB and the colors will shift on most viewers’ screens.
- Keep file sizes reasonable: under 1 MB for most posts, under 2 MB for thumbnails, under 10 MB for high-res covers. Smaller files load faster in feeds, which affects engagement.
- If you need to resize quickly, the Social Media Image Resizer on this site does it in your browser — no upload, no watermark, no sign-in.
