Why 400×400 for Profile Pictures?
400×400 is one of the most widely required sizes for profile pictures and avatars across social media platforms. It is twice the pixel density of 200×200, which means it looks sharp on Retina and high-DPI screens — increasingly important as most phones and laptops now have high-resolution displays.
Twitter/X officially stores profile photos at 400×400 and displays them at smaller sizes depending on context (48×48 in feeds, 200×200 on profiles). Uploading at 400×400 ensures maximum sharpness across all display sizes.
Profile Picture Requirements by Platform
| Platform | Recommended size | Display shape | Max file size |
|---|---|---|---|
| Twitter / X | 400×400px | Circle | 2MB |
| 400×400px | Circle | 8MB | |
| 170×170px (min 320×320) | Circle | None stated | |
| 320×320px (min) | Circle | None stated | |
| Discord | 128×128px (min) | Circle or square | 10MB |
| GitHub | 460×460px (recommended) | Circle | 1MB |
Other Uses for 400×400 Images
Team member photos
Company websites, "About Us" pages, and team directories often display headshots at 300–400px square. 400×400 is large enough to look sharp and small enough to load fast.
Podcast artwork
Podcast directories (Spotify, Apple Podcasts) require artwork at 3000×3000 for full quality, but 400×400 is used for preview thumbnails in feed readers and smaller displays.
App user avatars
Mobile apps, web apps, and SaaS platforms typically display user avatars at 64–128px but store them at 400×400 for Retina support. Upload 400×400 and the app will scale it down as needed.
Email signature photos
Professional email signatures include a headshot at around 100–150px display size. Upload 400×400 to your email client — it will display at the correct size while remaining sharp on all email clients.

Frequently Asked Questions
Is 400×400 the right size for a Twitter profile picture?▼
Yes. Twitter/X recommends uploading profile photos at 400×400px. The platform displays them at different sizes — 48×48 in tweet feeds, 200×200 on profiles — and scales your 400×400 down cleanly. Larger uploads (up to 2MB) are also accepted.
Why is 400×400 better than 200×200 for profile photos?▼
200×200 displays blurry on Retina and high-DPI screens, which now include most iPhones, MacBooks, and modern Android phones. 400×400 has 4× the pixels, so it appears sharp when the OS doubles the pixel density for Retina display.
Should I use JPG or PNG for profile pictures?▼
Use JPEG for headshots and photos — it compresses efficiently and keeps file size small. Use PNG only if your image has a transparent background (e.g., a logo) or very sharp edges that JPEG compression would blur.
Will my photo look good if it is not perfectly square?▼
The tool fits your photo within 400×400 while preserving the original aspect ratio. Non-square photos get white bars on the sides or top/bottom. For a professional look, crop your photo to square first using the Crop to Square tool.
What is the LinkedIn profile picture size?▼
LinkedIn recommends 400×400px for profile photos and accepts images up to 8MB. The photo is displayed as a circle. A 400×400 JPEG from this tool meets both requirements.
Are my files uploaded to a server?▼
No. All resizing happens entirely in your browser. Your images are never sent to any server.
