📏 YouTube channel art specs to respect

YouTube's help center specifies 2560 × 1440 px banners with a central 1546 × 423 px safe area for text and logos, and a 6 MB max upload size (YouTube Help). Snappa's 2025 update reinforces the same safe-zone dimensions and notes that the minimum upload is 2048 × 1152 px at a 16:9 ratio (Snappa).

Quick checklist for your YouTube channel art safe area 1546×423:

• Keep key CTAs and logos centered horizontally.
• Allow at least 210 px padding at top and bottom so TV crops look clean.
• Export in PNG for gradients or JPG for photography to stay under 6 MB.

🧠 How AI stretching keeps logos readable

Generative Expand in Photoshop extends canvases while matching lighting and textures, ideal for filling the edges of 16:9 channel art without cloning artifacts (Adobe Photoshop). When you pair it with Content-Aware Scale, you can lock your logo or host portrait while stretching low-detail spaces like skies or walls (MakeUseOf).

Benefits of an AI banner extender for YouTube workflow:

• No warping: Protect subjects before stretching to avoid elongated faces on TV screens.
• Consistent branding: Generate extra negative space for schedules, upload cadence, or value propositions.
• Speed: Save presets for 2560×1440 and 2048×1152 to batch different campaigns.

🛠️ Workflow: Stretch banners for every device

Use this repeatable sequence to stretch banner backgrounds without distortion:

1. Crop to final ratio. Start with 2560×1440 canvas and overlay a 1546×423 guide.
2. Protect focal points. Mask hosts, product renders, or logos before you stretch.
3. Expand edges. Run Generative Expand or background fill to add space on the sides for taglines.
4. Audit mobile view. Preview at 1546×423 to ensure text stays centered and legible on phones.
5. Export variants. Save both full-size and 2048×1152 versions for faster uploads when bandwidth is limited.

Thread long-tail keywords like “resize YouTube banner without cropping” into your asset library documentation so teammates can surface the playbook quickly.
