New Reddit card dimensions

New Reddit (redesign and mobile apps) shows link posts as cards with a large image above the title. The card image area is roughly 1.91:1 at about 600px wide. 1200 x 630 pixels is the target size.

Images smaller than 200 x 200 pixels may not display at all – you’ll get a text-only post.

Old Reddit thumbnail dimensions

Old Reddit (old.reddit.com) shows link posts as a list with small square thumbnails:

• List view: 70 x 70 pixels
• Expanded view: 140 x 140 pixels

Both views center-crop to a square. Keep your focal point centered if old Reddit matters to you.

File size limits

Embedly enforces a max of about 8MB, but larger images risk timeout failures. Keep OG images under 1MB.

Supported formats

• JPEG – best for photos, smallest files
• PNG – good for graphics, screenshots, text overlays
• GIF – only the first frame is used (no animation in previews)
• WebP – works through Embedly but JPEG/PNG are more reliable

Center-crop behavior

Both old and new Reddit center-crop images. New Reddit crops top and bottom to fit the 1.91:1 card. Old Reddit crops to a square. Keep key content (title text, logo, product shot) centered in your image and away from edges.

Multiple og:image tags

Embedly uses the first og:image tag it encounters. If your CMS or template injects an unintended og:image before yours, that one wins. When no OG image is present, Embedly ranks page body images by pixel dimensions and DOM position.
