Discord Image Sizes: Everything Is a Circle, and Most of It Is Tiny

Discord has more separate image slots than most platforms, and three constraints run through nearly all of them: the image gets cropped to a circle, it is displayed far smaller than you upload it, and the person looking at it is almost certainly on a dark background.

The Sizes

• User avatar — upload 512 × 512. Minimum 128 × 128. Displayed as a circle, around 40 pixels in a chat list.
• Server icon — 512 × 512, circular, displayed at about 48 pixels in the server sidebar.
• Profile banner — 600 × 240, a 5:2 strip.
• Server banner — 960 × 540, 16:9. Requires a boosted server.
• Invite splash — 1920 × 1080, the background shown on an invite link.
• Custom emoji — upload 128 × 128, under 256 KB. Displayed at roughly 32 pixels inline and 22 pixels as a reaction.
• Stickers — 320 × 320, under 512 KB.
• Role icons — 64 × 64, shown beside names at a few pixels.

Always upload the full recommended size even though the display is small. Discord generates the smaller versions, and giving it more to work with produces a cleaner result on high-density screens.

The Circle Crop Costs You a Fifth of the Frame

Avatars and server icons are square files displayed as circles. The corners are simply gone — and that is not a trivial trim. A circle inscribed in a square covers about 79% of its area, so roughly one pixel in five never appears.

What follows:

• Nothing meaningful in the corners. Ever.
• Centre the subject, and leave breathing room — a design that fills the square edge to edge will have its extremities sliced off on all four sides.
• Square logos with a visible border or frame look broken, because the frame’s corners vanish while its middle survives.
• Text across the full width gets its first and last characters clipped.

Before uploading, place a circle over your square design and look at what falls outside it.

Dark Mode Is the Default

This is the Discord-specific trap, and it catches brands more than anyone.

The overwhelming majority of Discord users run the dark theme. A logo exported on a white background — the version in every brand kit — becomes a glaring white disc in a dark sidebar. It does not look like a logo; it looks like a hole in the interface.

Discord supports transparency in avatars and emoji, so the fix is usually straightforward: export with a transparent background and let the dark interface show through. But check the result against both themes, because a logo that is itself dark or nearly black will then vanish instead.

If your mark only works on a light ground, give it a deliberate background colour rather than white — something from your palette that sits comfortably in a dark interface. And if you export to JPEG for any reason, you lose transparency entirely and get whatever fill the converter chose, which is frequently black.

Emoji: the 22-Pixel Problem

Custom emoji are the part of Discord people invest the most effort in and most often get wrong, because the preview in the upload dialogue is enormous and the real display is not.

An emoji is seen at about 32 pixels inline, and smaller still — around 22 pixels — when used as a reaction under a message. At that size:

• No text. Not one word. A word at 22 pixels is a grey smear.
• One shape, one idea. A face, an object, a gesture.
• Thick outlines or none. A one-pixel outline at upload size disappears entirely.
• Strong silhouette. The emoji has to be identifiable by its outline alone, because interior detail will not survive.
• Fill the frame. Padding inside the 128 × 128 makes an already-small emoji smaller.

Test by scaling your emoji to 22 pixels and placing it beside others. This is the same discipline a favicon demands, at an even less forgiving size.

For animated emoji the binding constraint is the 256 KB limit, not the dimensions. A GIF hits that ceiling quickly, so expect to reduce the frame count or shorten the loop rather than the resolution.

Banners Are Cropped Differently Everywhere

The 600 × 240 profile banner and the 960 × 540 server banner both have the interface sitting on top of them. A profile banner has the avatar overlapping its lower-left area; a server banner has the server name over it.

So treat banners the way you would any image with furniture on top: keep the subject away from the lower left and out of the top strip, and accept that the usable area is the middle and right.

File Upload Limits

Separate from image slots, Discord limits what you can attach to a message:

• 10 MB on a free account.
• 50 MB with Nitro Basic.
• 500 MB with full Nitro.

Boosted servers raise the limit for everyone in that server. If a file is a few megabytes over, compressing it is usually quicker than finding a link-sharing service — the limit is low enough that most ordinary photos and documents clear it easily once they are not camera-resolution originals.

Quick Reference

• Avatar and server icon: 512 × 512, cropped to a circle
• The circle removes about 21% of the square — keep everything central
• Emoji: upload 128 × 128, seen at 22–32 px, under 256 KB, no text ever
• Stickers 320 × 320; role icons 64 × 64
• Profile banner 600 × 240; server banner 960 × 540; invite splash 1920 × 1080
• Dark theme is the default — use transparency, never a white background
• Attachments: 10 MB free, 50 MB Nitro Basic, 500 MB Nitro
