Why Size Matters More Than Ever
Platforms crop, compress, and downscale images that don't match their native dimensions. Using the wrong size means:
- Cropping — faces, text, and key details get cut off
- Compression artifacts — platforms re-encode images not uploaded at native resolution, visibly reducing quality
- Feed display issues — wrong aspect ratio forces letterboxing or cropping in the feed
Uploading at the exact correct size gives you full control over what the viewer sees.
Instagram has the most format variety of any platform. Each format has its own ideal dimensions.
Feed Posts
| Format | Dimensions | Aspect ratio |
|---|---|---|
| Square | 1080×1080 px | 1:1 |
| Portrait (recommended) | 1080×1350 px | 4:5 |
| Landscape | 1080×566 px | 1.91:1 |
Portrait (4:5) is the best-performing feed format. It takes up the most vertical space in the feed — which means more scroll real estate and more attention.
Minimum width: 320 px. Maximum width: 1440 px (Instagram downscales above this).
Instagram Reels
| Spec | Value |
|---|---|
| Dimensions | 1080×1920 px |
| Aspect ratio | 9:16 |
| Minimum dimensions | 500×888 px |
| Video length | 3 seconds – 3 minutes |
| Max file size | 4 GB |
| Recommended formats | MP4, MOV |
Safe zone: The bottom ~35% of the screen is covered by the caption, username, and action buttons. Keep faces and important text in the top 60% of the frame.
Instagram Stories
| Spec | Value |
|---|---|
| Dimensions | 1080×1920 px |
| Aspect ratio | 9:16 |
| Image file size | Up to 30 MB |
| Video length | Up to 60 seconds |
| Recommended formats | MP4, MOV (video), JPG, PNG (image) |
Stories and Reels share the same canvas size. Safe zone rules apply: keep key content 250 px from the top and 400 px from the bottom.
Instagram Carousels
Same dimensions as single feed posts — 1080×1080, 1080×1350, or 1080×566. All slides must use the same aspect ratio. You can include up to 20 slides per carousel.
Instagram Profile Photo
Displays at 110×110 px in the feed. Upload at 320×320 px minimum for crisp quality across all devices.
TikTok
TikTok is a vertical-first platform. Every format is 9:16.
TikTok Videos

| Max file size | 287.6 MB (mobile), 500 MB (desktop) |
| Recommended formats | MP4, MOV |
| Recommended frame rate | 30fps or 60fps |
| Bitrate | At least 516 kbps |
Safe zone: TikTok overlays are heavy. The bottom 30% is covered by caption, username, and buttons. The right side has the action bar. Keep faces centered and key text in the middle 40% of the screen.
TikTok Profile Photo
Displays as a circle. Upload at 200×200 px minimum — higher resolution recommended.
YouTube
YouTube supports the widest range of resolutions because content lives permanently and is often watched on large screens.
YouTube Videos
| Resolution | Dimensions | Quality |
|---|---|---|
| 4K (Ultra HD) | 3840×2160 px | Best |
| 1440p (2K) | 2560×1440 px | Excellent |
| 1080p (Full HD) | 1920×1080 px | Recommended minimum |
| 720p (HD) | 1280×720 px | Acceptable |
Aspect ratio: 16:9 for standard videos. YouTube adds black bars to videos with other ratios.
Max file size: 128 GB. Max length: 12 hours.
Recommended formats: MP4 (H.264 codec), MOV, AVI.
YouTube Shorts
| Spec | Value |
|---|---|
| Dimensions | 1080×1920 px |
| Aspect ratio | 9:16 |
| Max length | 3 minutes |
| Max file size | 256 MB |
| Recommended formats | MP4, MOV |
YouTube Thumbnails
Thumbnails are one of the highest-leverage design assets on YouTube — they directly affect click-through rate.
| Spec | Value |
|---|---|
| Dimensions | 1280×720 px |
| Aspect ratio | 16:9 |
| Max file size | 2 MB |
| Formats | JPG, GIF, PNG, BMP |
Design thumbnails with bold, high-contrast text and a clear focal point. They display at a small size in search results — make sure they're readable at 200×113 px.
YouTube Channel Art (Banner)
| Spec | Value |
|---|---|
| Dimensions | 2560×1440 px |
| Safe zone for all devices | 1546×423 px (centered) |
| Max file size | 6 MB |
The banner displays differently across devices. Design your key content — logo, tagline — within the central 1546×423 px safe zone.
YouTube Profile Photo
Upload at 800×800 px. Displays as a circle in most contexts.
Feed Posts
| Format | Dimensions | Notes |
|---|---|---|
| Landscape (recommended) | 1200×630 px | Best for link previews and shared content |
| Square | 1080×1080 px | Best for image-only posts |
| Portrait | 1080×1350 px | Maximum portrait ratio Facebook supports |

| Dimensions | 1080×1920 px |
| Aspect ratio | 9:16 |
| Image duration | 5 seconds |
| Video length | Up to 20 seconds per story card |

Same specs as Stories — 1080×1920 px, 9:16, up to 60 seconds.
Facebook Cover Photo
| Context | Dimensions |
|---|---|
| Desktop display | 851×315 px |
| Mobile display | 640×360 px |
| Upload recommended | 1640×924 px (covers both contexts) |
Facebook Profile Photo

Facebook Event Cover Photo
1920×1005 px. Aspect ratio approximately 1.91:1.
Pinterest is portrait-dominant. Vertical pins take up more feed space and consistently outperform other orientations.
Pinterest Pins
| Format | Dimensions | Aspect ratio | Notes |
|---|---|---|---|
| Standard (recommended) | 1000×1500 px | 2:3 | Best for discovery and reach |
| Square | 1000×1000 px | 1:1 | Acceptable, less prominent |
| Long pin | 1000×2100 px | 1:2.1 | Pinterest clips to 1:2.1 max in feed |
| Story pin | 1080×1920 px | 9:16 | Full-screen format |
Avoid going longer than 1:2.1. Pinterest crops anything taller in the feed, hiding the bottom of your content.
Max file size: 20 MB for images. Formats: JPG, PNG, GIF (static).
Pinterest Video Pins
| Spec | Value |
|---|---|
| Dimensions | 1:1, 2:3, or 9:16 |

Aspect Ratios Cheat Sheet
If you work in ratios rather than pixel dimensions:
| Ratio | Name | Where it's used |
|---|---|---|
| 9:16 | Vertical full-screen | TikTok, Reels, Stories, Shorts — the universal vertical format |
| 4:5 | Portrait | Instagram feed best-performer — taller than square, not full screen |
| 1:1 | Square | Universal — works everywhere |
| 16:9 | Landscape widescreen | YouTube, Twitter, LinkedIn articles |
| 1.91:1 | Landscape | Facebook feed, link previews |
| 2:3 | Pinterest portrait | Pinterest standard pin |
Universal Design Rules for Every Platform
1. Design for mobile first. Over 90% of social media is consumed on phones. Preview every design on a phone screen before posting.
2. Keep text in the safe zone. Every vertical-format platform has overlays — captions, usernames, buttons — covering the top and bottom of the screen. Keep your key content in the central 60% of the frame.
3. Use the native resolution. Don't upscale a small image to fill the required dimensions. Upscaling doesn't add resolution — it just blurs. Start at the correct size.
4. Export at 72 dpi for images. Screen resolution is 72 dpi. Designing at 300 dpi (print resolution) creates unnecessarily large files that get compressed more aggressively by platforms.
5. Use sRGB color profile. Social platforms display sRGB. If you design in Adobe RGB or P3, colors may shift on upload.
6. Check your file size limits. Large files take longer to upload and may be rejected. Compress images with a tool like Squoosh or TinyPNG before uploading.
File Format Guide
| Format | Best for | Notes |
|---|---|---|
| JPG | Photos, complex images | Smaller file size, slight quality loss |
| PNG | Graphics with text, logos, transparent backgrounds | Larger file, no quality loss |
| GIF | Short animations | Limited to 256 colors, large file sizes — avoid if MP4 is an option |
| MP4 | All video | Universal format, best compression |
| MOV | Video (Apple native) | Larger than MP4, but accepted everywhere |
| WebP | Images (where supported) | Better compression than JPG/PNG, not yet accepted on all platforms |
For video, always use MP4 with H.264 encoding. This gives you the widest compatibility and best quality-to-file-size ratio across every platform.
Posting Across Platforms Without Resizing Every Time
The most time-consuming part of a multi-platform strategy isn't creating content — it's adapting it for every format.
The practical workflow:
- Design at 1080×1920 px (9:16) — this is the universal vertical canvas. It works for TikTok, Reels, Stories, and Shorts.
- Export a 1080×1350 px (4:5) crop — for Instagram feed and Facebook feed.
- Export a 1080×1080 px (1:1) crop — for anywhere square format is needed.
Three exports from one design covers almost every platform.
When you're scheduling across TikTok, Instagram, YouTube, Facebook, Threads, and Pinterest, PostLink lets you upload once and post everywhere — without jumping between apps or reformatting separately for each platform.
