What size are custom emojis on Discord?

Discord custom emojis upload at 128×128 pixels (max 256KB, PNG or GIF) and display at 32×32 in chat.

What size are Twitch emotes?

Twitch emotes require three sizes: 28×28, 56×56 and 112×112 pixels as transparent PNGs under 1MB each.

Why do emotes need to be so small?

Emotes render inline with chat text, so platforms display them at 28–32 pixels. Designs with bold shapes and few colors — like pixel art — stay readable at that size.

What those sizes actually look like

Numbers lie; pixels don't. Here's the same dancing banana at each platform's real rendered size — notice how fast detail disappears. That's why bold pixel art wins chat.
