1. Header & Profile Photo: Brand First Impressions
Header Photo
- Size: 1,500 × 500 px – The 3:1 ratio ensures it fits X’s header space, but cropping varies by device:
- Desktop: Shows full width, but top/bottom may be trimmed (focus on middle 400px height).
- Mobile: Crops left/right (only ~600px width visible).
- Tip: Use a “safe area” (800 × 400 px centered) for logos, taglines, or key imagery—this stays visible across devices. Avoid text near edges.
Profile Photo
- Size: 400 × 400 px – X displays it as a circle, so keep logos/faces 10–15% away from square edges to avoid cuts.
- Tip: Use a high-contrast image (e.g., bold logo, clear headshot) – it needs to stand out in small feed previews.
2. Post Images: Engage in Feeds
- Size: 1,024 × 512 px (2:1 ratio) – X’s preferred size for standard post images; it loads fast and doesn’t get compressed heavily.
- Tips:
- For multiple images (2–4 per post): X arranges them in a grid—ensure each image follows the 2:1 ratio to avoid uneven cropping.
- Avoid text-heavy images: Feeds are scanned quickly; focus on clear visuals (e.g., product shots, infographics) instead of small text.
3. Cards & Summary Images: Boost Link Clicks
Cards Image (Promoted Content)
- Size: 800 × 320 px (2.5:1 ratio) – Used for promoted links, ads, or branded content. A sharp image here increases click-through to your website.
- Tip: Pair with concise text (under 100 characters) – X’s ad algorithm favors visuals that complement copy.
Summary Card Image
- Size: 280 × 150 px – The thumbnail that appears when you share a link (e.g., blog post, product page).
- Tip: Test previews with X’s “Card Validator” – fix blurry or missing thumbnails to make links look credible.
