A practical image size guide for websites and social media

Pixel dimensions, aspect ratios and file formats for the places images actually go — website heroes, blog posts, Instagram, LinkedIn, Facebook, X and print — and how to get them from a Photofolio download.

Every Photofolio purchase is a full-resolution JPEG, typically 4,000–8,000 pixels on the long edge. That is far more than any screen needs, which is the point: you resize down for each use and never up. Here are the sizes that matter in 2026.

Websites

  • Full-width hero: 1920 × 1080 for most sites; 2560 × 1440 if you want to look sharp on large retina displays. Aspect ratio 16:9, or wider (2.4:1) for slim banners.
  • Blog and article images: 1200 × 800 (3:2) or 1200 × 675 (16:9). Also the size most sites use for social sharing cards.
  • Thumbnails and cards: 600 × 400.
  • Serve WebP or AVIF where your platform supports it; keep a JPEG fallback. Aim for under 200 KB for heroes on mobile.

Social media

  • Instagram feed: 1080 × 1350 (4:5) gets the most screen; 1080 × 1080 square is safe.
  • Instagram / Facebook Stories and Reels, TikTok: 1080 × 1920 (9:16). Keep text and faces out of the top and bottom 250 px.
  • LinkedIn post image: 1200 × 627 (1.91:1). Company page cover 1128 × 191.
  • Facebook post: 1200 × 630. Cover 820 × 312.
  • X: 1600 × 900 (16:9).
  • Pinterest: 1000 × 1500 (2:3).

Print

Work at 300 dpi: an A4 page needs about 2480 × 3508 pixels, an A3 3508 × 4961. Most of our files comfortably cover A3 and many cover A2. The image page lists the pixel dimensions before you buy.

Orientation matters more than size

The biggest practical problem is not resolution but shape: a landscape image will not become a Story without a brutal crop. Use the orientation filter on any Photofolio search, or start from our vertical collection or hero image collection.
