The YouTube channel banner — also called Channel Art — is the large header image that occupies the top of your channel homepage. It is the first visual impression a visitor forms before they watch a single video, and a well-crafted banner communicates your channel’s subject matter, personality, and content cadence instantly. The unique challenge of the YouTube banner is that the same image must work across four distinct display environments — television, desktop, tablet, and mobile — each of which shows a different portion of the image. This guide explains exactly what each device displays, defines the safe zone, and offers actionable design guidance.
| Device / Specification | Visible Area (pixels) | Notes |
|---|---|---|
| Recommended upload size | 2560 × 1440 pixels | Full canvas — use this as your design base |
| Smart TV display | 2560 × 1440 pixels | Full image visible |
| Desktop browser | 2560 × 423 pixels (top strip) | Full width, cropped to top 423px height |
| Tablet | 1855 × 423 pixels (centered) | ~353px trimmed from each side |
| Mobile (smartphone) | 1546 × 423 pixels (centered) | ~507px trimmed from each side |
| Universal safe zone | 1546 × 423 pixels (centered) | Visible on ALL devices — place key content here |
| Minimum recommended size | 2048 × 1152 pixels | Below this, quality degrades on large screens |
| Maximum file size | 6 MB | — |
| Supported formats | JPG, PNG, GIF (static), BMP | Animated GIFs not supported |
On smart TV YouTube apps, the channel banner renders at the full 2560×1440 pixel resolution — the only viewing environment where the entire image is visible. This means you can design decorative elements in the outer regions of the canvas knowing they will appear on television. However, since most YouTube audiences consume content on mobile or desktop rather than TV, the outer regions should be treated as visual enhancements, not the home for critical information.
On desktop browsers (Chrome, Safari, Firefox), the banner appears as a horizontal strip spanning the full browser window width. The height is fixed at approximately 423 pixels, cropped from the top of the image. The bottom 1,017 pixels of your 1440-pixel-tall canvas are never shown on desktop. The full 2560-pixel width is displayed, but only the topmost 423 pixels of height are visible.
On tablets (iPad, Android tablets), YouTube shows a centered portion of the banner approximately 1,855 pixels wide and 423 pixels tall. This means approximately 353 pixels are trimmed from each side of the full-width image. Content placed in the outer 353-pixel margins on each side will not be visible to tablet users.
On smartphones, the visible banner width narrows further to approximately 1,546 pixels at 423 pixels tall. This is the most restrictive display environment and the basis for the universal safe zone. About 507 pixels are cropped from each side of the full 2560-pixel width. The majority of YouTube viewership occurs on mobile, making this the most important device to design for.
Based on the display ranges above, YouTube recommends keeping all critical content — text, logos, and key visual elements — within the central 1546×423 pixel area of the full 2560×1440 canvas. Anything outside this safe zone may be invisible to a portion of your audience depending on their device.
Think of your banner as a wide panoramic painting measuring 2560×1440 pixels:
Your design must ensure that the safe zone (central 1546×423 pixels) reads as a complete, self-contained design when isolated, while the full canvas looks balanced and intentional when viewed on a television.
Unlike Stories or social media posts, channel banners do not need to be updated frequently. The most appropriate moments to refresh yours include:
