Platform-by-Platform Details
X (formerly Twitter)
X recommends 400 × 400 px for profile icons.
- Timeline display: Scaled down to about 48 × 48 px
- Header image: 1500 × 500 px (3:1)
- File limit: 2 MB for both icon and header
- Formats: JPG, PNG, GIF (animated GIFs supported)
Header images may have their top and bottom ~60 px cropped on some devices, so keep important content centered.
Instagram displays profile icons at 320 × 320 px, but uploading at 720 × 720 px or larger is recommended for clarity.
- Minimum: 110 × 110 px
- Recommended upload: 720 × 720 px+
- Highlight icons: 320 × 320 px (circle)
Instagram is mobile-first, so icons appear relatively small. They're larger on the profile page, though, so higher-resolution source images help.
Facebook displays profile images at different sizes depending on the device.
- Desktop: 176 × 176 px
- Mobile: 128 × 128 px
- Recommended upload: 320 × 320 px+
- Cover image: Desktop 820 × 312 px / Mobile 640 × 360 px
The cover image's visible area differs between desktop and mobile, so center important elements.
LINE
LINE recommends 640 × 640 px — larger than most other platforms.
- Profile image: 640 × 640 px (circle)
- Background image: 720 × 1280 px
- Chat view: Shown at a smaller size, but full size on the profile screen
YouTube
YouTube channels use 800 × 800 px profile images — the largest recommendation among major platforms.
- Recommended: 800 × 800 px
- File limit: 2 MB
- Banner image: 2560 × 1440 px (accounts for TV display)
YouTube considers TV-screen viewing, so prepare a high-resolution image.
TikTok, Threads & Bluesky
| Platform | Profile Image | Header / Cover |
|---|---|---|
| TikTok | 400 × 400 px | None |
| Threads | 400 × 400 px | None |
| Bluesky | 400 × 400 px | 1200 × 675 px |
All three recommend 400 × 400 px. Threads may pull your Instagram profile image automatically since the accounts are linked.

Design for Circular Cropping
Since every platform crops to a circle:
- Center faces and logos — the corners will be clipped
- Leave margin — don't place text near the edges
- Keep it simple — the image needs to be recognizable even at very small sizes
Why Images Look Blurry (and How to Fix It)
The main cause is insufficient resolution.
- Use the recommended size or larger for each platform
- Avoid over-compressing JPEGs — keep quality at 80% or above
- Never upscale — stretching a small image always degrades quality
Benefits of a Consistent Profile Image Across Platforms
If you manage multiple social accounts, using the same profile image everywhere builds brand consistency:
- Recognition: Followers instantly identify you across platforms
- Trust: A unified visual identity looks professional
- Discoverability: Fans from one platform can find you on another
For a unified image, create it at the largest size needed — YouTube's 800 × 800 px — and upload the same file everywhere.

FAQ
What pixel size is best for a social media profile image?
It depends on the platform: X is 400 × 400 px, Instagram 320 × 320 px (720 × 720 px+ recommended), LINE 640 × 640 px, YouTube 800 × 800 px. When in doubt, create your image at 800 × 800 px and it will work everywhere.
Why does my profile image get cropped into a circle?
All major social platforms display profile images as circles. Square uploads have their corners automatically clipped, so keep important elements (face, logo, text) in the center.
Can I resize a phone photo for use as a profile image?
Yes. sakutto's image resize tool works directly in your mobile browser — no app installation needed. Choose an SNS preset and download the resized image instantly.
What size should I make one image that works on all platforms?
Create it at 800 × 800 px (YouTube's recommendation, the largest among major platforms). Each platform will scale it down automatically, and starting large preserves quality.
Should I use JPG or PNG for my profile image?
Use JPG for photos and PNG for logos or images that need transparency. JPG is lighter and uploads faster; PNG preserves sharp edges. Stay within each platform's file size limit (X: 2 MB, YouTube: 2 MB, etc.).
Summary
Profile image sizes vary by platform — X at 400 × 400 px, Instagram at 320 × 320 px, LINE at 640 × 640 px, and YouTube at 800 × 800 px. All platforms crop to a circle, so center your key visual elements. For a single image that works everywhere, create it at 800 × 800 px and use an online tool to resize for each platform.
