Reddit Image Sizes — Post, Banner & Community Icon Dimensions
Reddit serves the same image across desktop feeds, the official mobile app, third-party clients, and the old.reddit interface — each of which crops and scales differently. Uploading at the right dimensions keeps post previews sharp and stops community banners from chopping off important content on mobile.
All Reddit Dimensions
Posts
- 1200 x 675 — Post image (16:9, recommended for feed previews)

- Upload up to 20 images per gallery post; max 20MB per file
Supported Formats
- PNG, JPG, GIF, WEBP for static images

Community Branding

- Mobile crops the banner aggressively — keep critical content centered

Reddit Post Image Size
The recommended Reddit post image size is 1200 x 675 pixels (a 16:9 aspect ratio), with a hard cap of 20MB per file. Reddit accepts PNG, JPG, GIF, and WEBP for static images. Feed cards render previews at 16:9, so a 1200 x 675 image fills the preview cleanly, while taller or square uploads get letterboxed with bars on either side.
For multi-image posts, Reddit gallery posts hold up to 20 images, each subject to the same 20MB limit. Reddit re-encodes large uploads, so compress photos before posting — use JPG for photographic content and PNG for graphics, logos, and infographics with sharp edges or text.
Reddit Community Banner Size
The Reddit community banner — the wide header on a subreddit’s page — is 1920 x 384 pixels (a 5:1 aspect ratio), capped at 10MB in PNG or JPG. It runs full-width across the top of the subreddit on desktop, behind the community name and icon.
Safe zone: the official mobile app crops both sides of the banner hard, so keep logos, taglines, and key art inside the central 50% of the canvas. Anything near the far left or right edge is the first thing to disappear on a phone.
Reddit Community Icon Size
The Reddit community icon (also the avatar shown next to posts) is 256 x 256 pixels (1:1) and is masked to a circle everywhere it appears — the subreddit header, feed cards, and comment threads. Upload it as PNG or JPG under 500KB.
Because it renders small and circular, keep the mark centered with at least 10% padding on every side so the circular crop doesn’t clip it. The Discord server icon follows the same circular-crop rule but wants a 512 x 512 upload, so one master file at 512 covers both — and the Discord PFP size guide covers the personal-avatar equivalent.
Reddit Profile Banner Size
The Reddit profile banner — the header on your user profile, not a subreddit — is 1920 x 384 pixels(5:1), capped at 10MB. It shares the community banner’s dimensions but is a separate slot: this one sits behind your username and snoo avatar on your personal profile page.
The same crop rules apply — the mobile app trims the sides, so center anything you can’t afford to lose. For another wide channel-art spec with published safe zones, compare the YouTube banner size guide.
Reddit Image Optimization Tips
- Design for 16:9 feed previews: taller or square images get letterboxed in the feed card. A 1200x675 image fills the preview cleanly without cropping the subject.
- Center content in community banners: the 1920x384 banner is built for desktop, and the mobile app crops both sides hard. Keep logos, taglines, and key art inside the middle 50% of the canvas.
- Use galleries for multi-image posts: Reddit gallery posts support up to 20 images and tend to outperform single-image posts in image-heavy subreddits.
- Pick PNG for graphics, JPG for photos: Reddit re-encodes large uploads, and JPG holds up better on photographic content. Keep PNG for text, logos, and infographics that have sharp edges.
- Mind the avatar crop: avatars and community icons render as circles at small sizes. Upload a 256x256 image with the subject centered and at least 10% padding on every side.
- Stay under the file caps: 20MB is the per-image hard limit. Compress photos before uploading so the post doesn’t silently fail on slower connections.

Frequently Asked Questions
What size should a Reddit post image be?
Upload Reddit post images at 1200x675 pixels (16:9) for the best feed preview. The maximum file size is 20MB, and Reddit accepts PNG, JPG, GIF, and WEBP. Taller or square images get letterboxed in the preview card, so 16:9 keeps the subject filling the frame.
What is the Reddit community banner size?
The Reddit community banner is 1920x384 pixels (5:1) on desktop. The mobile app crops the sides aggressively, so keep logos, taglines, and key visuals centered within the middle 50% of the canvas. The banner is one of the first things visitors see when they land on a subreddit, so treat it as a wide centerpiece, not a billboard.
What size is a Reddit avatar or community icon?
Reddit avatars and community icons are 256x256 pixels (1:1) and are cropped to a circle. They display small in feeds and comment threads, so use a clean, centered mark with plenty of padding around the edges so nothing gets clipped by the circular mask.
What is the Reddit profile banner size?
The Reddit profile banner — the header on your user profile — is 1920x384 pixels (5:1), capped at 10MB. It shares the community banner’s dimensions but is a separate slot that sits behind your username on your personal profile page. The mobile app crops the sides, so keep key content centered.
Can you upload multiple images to a Reddit post?
Yes. Reddit supports gallery posts of up to 20 images, with each image capped at 20MB. Galleries display as a swipeable carousel and tend to perform well in image-heavy subreddits compared to single-image posts.
What image formats does Reddit support?
Reddit accepts PNG, JPG, GIF, and WEBP for static images, and MP4 or MOV for video. Use PNG for graphics with text or sharp edges and JPG for photographs — Reddit re-encodes large uploads, and JPG tends to hold up better on photographic content.
