YouTube Banner Size: 2560×1440 and the Safe Area That Saves You

One guide says the YouTube banner safe area is 1235×338 pixels. Another says 1546×423. A third tells you to design at 2560×1440, but your file comes out of your template tool at a "16:9" size that YouTube rejects. You upload anyway, and the result is a channel name sliced on mobile, a logo invisible on TV, and a banner that looks blurry where it used to look crisp on the designer's mockup.

This is the most common creator frustration with channel art, and it has nothing to do with design skill. It happens because the numbers that actually govern a YouTube banner are spread across conflicting third-party guides, and most of them quietly skip the one figure that decides whether your text survives — the safe area. This guide is based on YouTube's official help documentation and hands-on testing with real uploads, so every number below can be checked against the source rather than taken on trust.

The YouTube banner size numbers that actually matter

YouTube documents channel branding specs in one place, and the list is shorter than most guides make it look. These are the figures you should build around:

The only hard numbers you must memorize are 2560×1440 (design target), 2048×1152 (absolute minimum), and 6 MB (file cap). Everything else on this page is about how those three interact with cropping.

Why the safe area numbers conflict — and which one you should use

Here is the exact reason guides contradict each other, and once you see it you'll never be confused by it again. YouTube's official documentation states that the safe area — the band where text and logos are guaranteed to stay visible on every device — is 1235 × 338 pixels. What most guides leave out is the measuring stick: that figure is given on the 2048 × 1152 minimum canvas.

If you design at the recommended 2560 × 1440 size instead, that same region scales up by the ratio of the two canvases (2560 ÷ 2048 = 1.25), which gives you about 1546 × 423 pixels. That is a conversion of the official figure, not a second specification. A guide quoting 1235×338 and a guide quoting 1546×423 are quoting the same official number at two different design sizes — and neither is wrong.

How to use it in practice:

• If you work on a 2048 × 1152 canvas, keep your channel name and logo inside the central 1235 × 338 band.
• If you work on a 2560 × 1440 canvas (the recommended size), keep them inside the central ≈1546 × 423 band.
• Everything critical — channel name, tagline, upload schedule, website — belongs in that central strip. The further out you place text, the more devices will cut it.

One image, three crops: how mobile, desktop, and TV differ

The single image you upload is displayed in at least three very different ways, and understanding this is what turns the safe area from a confusing number into an obvious habit:

• TV: shows the full 2560 × 1440 frame. This is why the recommended size is tied to TV — a smaller canvas gets stretched and softened on a big screen.
• Desktop: shows a wide, centered strip of the banner. In practice most of the middle band is visible, and the desktop display of the safe area is exactly where the 1546 × 423 figure (at the recommended canvas) comes from.
• Mobile: shows little more than the center of the image, close to a 1:1 region around the middle. The left and right thirds of your banner effectively do not exist on phones.

The practical consequence: the safe area is the intersection of every device crop. Put your channel name, logo, and tagline in the middle, and use the outer thirds for atmosphere — texture, scenery, a color wash, visual noise that does not need to be read. A banner designed this way survives all three crops at once.

Common banner mistakes (and how to fix each one)

Most "why is my banner broken" threads on Reddit come down to a small set of repeatable mistakes. Here is the full list, with the fix:

Why every YouTube banner size guide says something different

Search "youtube banner size" and you will see 2560×1440, 2048×1152, 6 MB, 4 MB, 1235×338, and 1546×423 all in the first page of results — sometimes in the same article. The contradictions are worth naming, because they are exactly where creators get burned:

• The 6 MB vs 4 MB conflict. YouTube's official help page states a 6 MB file-size limit for channel branding. Canva's documentation has, at times, told users the limit is 4 MB. Only one of those can be right, and the official YouTube figure is 6 MB. When a guide disagrees with YouTube's own help page, trust YouTube's page.
• The safe area omission. The majority of template tools and third-party tutorials never mention the safe area at all, or show it as a one-size-fits-all box without explaining which canvas it belongs to. That omission is why so many people upload perfectly sized banners and still lose their channel name on mobile.
• The canvas mix-up. Guides that quote 1235×338 and guides that quote 1546×423 are both quoting YouTube — from different design canvases, as explained above. The contradiction disappears once you know the measuring stick.

The check you can always run yourself: open YouTube's official help page on channel branding, and confirm the figure against your own test upload using the live preview on mobile, desktop, and TV. Two minutes of verification beats trusting a random blog that copied another blog.

Getting the exact size without doing the math

You now know the numbers, but knowing them and producing a file that hits them are two different jobs — which is exactly where most creators lose the afternoon: resizing in a generic editor, guessing the safe area by eye, re-exporting until the uploader stops complaining.

A dedicated tool removes that entire loop. The Vogoo AI YouTube Banner Maker opens on a locked 2560 × 1440 canvas (with a 2048 × 1152 minimum option), draws the safe area onto the image so you can see where the 1546 × 423 central band sits before you place anything, and downloads the file at the exact target pixel dimensions instead of a browser-rescaled approximation. You describe your channel in a prompt, check the center band, and download a file that is already the size YouTube asks for. If you want to style a matching avatar or thumbnail while you are at it, the same account can generate standalone images with Vogoo Text to Image, and if you need help describing your channel visually, our AI picture prompt guide covers prompt structure in depth.

That is the whole trick: the correct YouTube banner size is not a secret — it is 2560 × 1440 with a 6 MB cap and a safe area you must respect — but the reliable way to hit it is to make the canvas itself enforce the spec, so you can spend your time on the art instead of the file. Try the banner maker with your channel's description and see your first correctly-sized banner export in a couple of minutes.

FAQ

What is the recommended YouTube banner size?

2560 × 1440 pixels is the size YouTube recommends, especially for TV, and it should be your design target. The minimum upload is 2048 × 1152 pixels at 16:9, and anything below that is rejected.

Is the YouTube banner safe area 1235 × 338 or 1546 × 423?

Both figures describe the same region: 1235 × 338 px is the official safe area measured on the 2048 × 1152 minimum canvas, and ≈1546 × 423 px is that same region scaled onto the 2560 × 1440 recommended canvas. Use the figure that matches the canvas you design on.

What is the minimum YouTube banner size I can upload?

2048 × 1152 pixels at a 16:9 ratio is the smallest accepted upload. A smaller file — even one with the correct 16:9 shape — will be rejected on upload.

Why does my YouTube banner look blurry after uploading?

Your source image almost certainly had too few pixels for the slot. YouTube recompresses channel art, so a banner that starts below the minimum canvas softens further. Design at 2560 × 1440 or at least 2048 × 1152 to keep it sharp.

How big can my YouTube banner file be?

6 MB is the official file-size limit for channel branding. Keep exports under that — a 2560 × 1440 JPG is usually well below 1 MB — and avoid oversized uncompressed PNGs.

Will my banner be cropped on mobile?

Yes. Mobile shows only the central region of the image, close to a 1:1 area around the middle, while desktop shows a wide strip and TV shows the full frame. Keep text and logos inside the safe area so they survive the mobile crop.
