Reddit Image Size Cheat Sheet 2026

Q: What is the best Reddit post image size?

The recommended Reddit post image size is 1200x628 pixels. This displays well in both card and classic view layouts. Reddit supports JPEG, PNG, and GIF formats up to 20 MB for image posts.

Q: What size is the Reddit avatar?

Reddit avatars should be 256x256 pixels. The image is displayed as a circle next to your posts and comments. Custom image uploads are separate from Reddit's Snoo avatar creator.

Q: What is the Reddit community banner size?

Reddit community banners should be 1920x384 pixels. This wide format covers the full width of the community page header. The visible height varies between desktop and mobile, so center important content vertically.

Q: Does Reddit compress uploaded images?

Reddit does compress images on upload, particularly large files. For the best quality, upload at the recommended dimensions and keep file sizes under 5 MB. Reddit also converts some formats during processing.

Reddit supports image posts, user avatars, and community banners at specific dimensions. Post images display best at 1200x628 (matching the standard link preview ratio), avatars at 256x256, and community banners at 1920x384. Properly sized images look professional and help posts and communities stand out. FastEdit makes it easy to hit these dimensions.

Before you upload

Reddit displays images differently in card view (large preview) vs classic view (thumbnail): design for card view since it is the default.
Community banners are cropped to different heights on mobile vs desktop: keep important content in the center vertical third.
Post images with readable text overlays perform well on Reddit since many users browse in card view mode.
Use PNG for screenshots and graphics with text; use JPEG for photographs to keep file sizes manageable.
