YouTube Community Post Image Size Guide

A practical reference for creators publishing still-image updates and promo graphics in Community posts.

YouTube Community posts do not need the same exact design treatment as thumbnails, but they still benefit from clear aspect ratio planning and readable text. In practice, square and portrait-friendly promotional layouts tend to hold up better than overly wide designs.

Best practical approach

• start with clean high-resolution source art
• prefer balanced square or portrait-friendly layouts for readability
• keep text large enough to survive mobile previews
• reuse thumbnail-safe contrast habits when promoting video content

What to avoid

Avoid tiny caption blocks, weak contrast, or landscape graphics that depend on fine edge detail. Community posts are often consumed quickly in-feed, so clarity matters more than visual complexity.
