Evaluate the 851x315 canvas for community headers and project banners
851x315 forms a custom shallow header around 2.7:1. Keep logos, faces, and key banner text away from the extreme horizontal edges where responsive containers may tighten.
- Approximately 2.7:1, with an exact 851x315 output canvas
- Check subject scale and edge clearance at native size for community headers and project banners
- JPG or WebP suits photographic headers; PNG is better for flat brand artwork
