YouTube Channel Banner
Downloader + Safe-Zone Checker
Save any channel's banner at the full 2560×1440 source resolution — or flip the switch and check your own design before you upload: YouTube's size rules plus a pass/fail verdict for every device crop, computed from where your design actually puts its detail.
- ● Safe-zone checker: pass/fail per device
- ● Full-res source downloads
- ● TV / desktop / tablet / mobile crops
- ● YouTube's rules, applied
Full 2560×1440 source, safe-zone overlay, and per-device crop downloads.
Upload the design before YouTube sees it: size rules, aspect ratio, file weight and a per-device verdict computed from where your detail actually sits.
TV keeps the full frame; phones keep a 1546×423 strip. The checker and the downloads both speak in real device crops, not one blurry preview.
The checker runs entirely in your browser on a canvas — your unreleased artwork never touches a server.
Banners come straight from Google's image CDN at source resolution, with TV, desktop, tablet and mobile variants one click each.
Reference
The crop sheet
One 2560×1440 upload feeds every screen. These are the exact crops — and the rules the checker applies. The verdict thresholds are printed too, so a pass means something you can verify.
| Fact | Value | Why it matters |
|---|---|---|
| TV crop | 2560×1440 · 100% | Sees the full upload |
| Desktop crop | 2560×423 · 29.4% | Full-width strip |
| Tablet crop | 1855×423 · 21.3% | Narrower strip |
| Mobile · safe zone crop | 1546×423 · 17.7% | The strip every device keeps |
| Minimum upload | 2048×1152 | YouTube rejects anything smaller |
| Recommended | 2560×1440 · 16:9 | Sharp on TV, no upscaling |
| Max file size | 6 MB | The upload hard limit |
| Verdict math | quiet < 2.5 · pass < 0.45 · fail ≥ 0.9 | Outside/inside detail-density ratio per device |
How to
Ship a banner that survives every screen
Paste a competitor's handle and download their banner with the safe zone overlaid — see exactly how they use the strip.
Full frame for TV, but treat the 1546×423 centre as the real canvas — that's all a phone keeps.
Drop your file into the checker: size rules plus a pass/caution/fail per device, computed from your actual pixels.
Move anything the verdicts flag into the safe zone and re-run — a clean sheet means no surprises in Studio.
Who it's for
From design reference to upload confidence
Channel designers run every client deliverable through the checker — the per-device verdicts turn "trust me, it'll crop fine" into a sheet the client can read.
Creators rebranding pull banners from the channels they admire, study how the safe zone is used, then verify their own take against the same crops before switching.
Brand & compliance teams check that logos, schedules and sponsor marks sit inside the strip that actually renders on phones — where most subscribers are.
Agencies archive full-resolution banner art across a client roster for redesign references, without asking anyone for source files.
Two modes
Grab theirs or check yours
Same geometry, two directions: the downloader pulls any channel's art with the crops marked; the checker points that machinery at the file you're about to upload.
Any channel's banner

Which should I use?
Researching a niche or collecting references — the downloader, straight from the handle. About to upload new art — the checker, every time; it costs one drag and catches the crop mistakes Studio only shows you after publishing.
One tool, every intent
However you searched for it, this is the page
People land here to download channel art, to find the youtube banner size, or to check the banner safe zone. One geometry answers all three.
Banner size, settled
2560×1440 to design, 2048×1152 minimum, 1546×423 safe zone, 6 MB limit — the whole spec sheet lives in the reference table above, and the checker enforces it on your actual file.
Channel art downloader, honest
The asset comes from Google's own image CDN at source resolution. Use it for reference and research — re-uploading someone else's artwork as your own is copyright infringement.
Safe zone, visualised
Every preview on this page draws the 1546×423 strip in place — on their banner and on yours. If a template ever told you "keep it in the middle-ish", this is the exact rectangle it meant.
A checker, not a vibe
The verdicts are computed from your pixels with thresholds printed on the page — re-run it after every edit and watch the ratio move. No AI, no opinion, just geometry and gradients.

FAQ
Frequently asked questions
How do I download a YouTube channel's banner?+
Paste the channel's handle (@name), URL or UC… ID above. The tool resolves it through the official YouTube Data API, reads the banner's source image from Google's CDN and gives you the full-resolution file plus TV/desktop/tablet/mobile variants.
What is the banner safe zone?+
The 1546×423 central strip that stays visible on every device. TV shows your full 2560×1440 upload, desktop and tablet show wider strips, and phones keep only the safe zone — anything outside it can be cropped away.
How does the safe-zone checker decide pass or fail?+
Deterministically, with the math printed on this page: your image is scanned for visual detail (luminance edges), and each device compares the detail density in the bands it crops away against the strip it keeps. Quiet bands pass; bands nearly as busy as the visible strip fail. File checks (2048×1152 minimum, 16:9, 6 MB) apply YouTube's published rules.
What size should my banner be?+
Design at 2560×1440 (16:9). YouTube rejects uploads under 2048×1152 and over 6 MB. Keep text, faces and logos inside the 1546×423 safe zone — the checker overlays it on your file so you can verify before uploading.
Does it work if the channel has no banner?+
If a channel never uploaded banner art, YouTube has no asset to serve — we tell you explicitly instead of returning a broken image.
