If you've searched for "youtube channel banner size 2560 x 1440 safe area 1546 x 423 file size 6mb" or wondered about the "1235 x 338 banner" size, you're not alone. YouTube's banner requirements can be incredibly confusing because your one image has to scale across TVs, desktops, and mobile phones.

The Master Canvas: 2560 x 1440

First, your actual uploaded image must be exactly 2560 x 1440 pixels. This is the TV display size. If you upload anything smaller, YouTube might reject it. It also must be under the 6MB file size limit.

The Safe Areas: 1546x423 vs 1235x338

The "safe area" is the middle strip of your 2560x1440 image that is guaranteed not to get cropped off on smaller screens.

1546 x 423 (The Standard Desktop/Mobile Safe Area)

This is the most common safe area. If you keep all your logos, text, and important branding within the middle 1546x423 pixels of your canvas, it will look perfect on desktop monitors and most modern smartphones.

1235 x 338 (The Ultra-Safe / Legacy Device Area)

Some templates reference 1235x338. Why? Because on older, very small mobile screens or certain app layouts, YouTube crops even tighter. Designing for 1235x338 guarantees that absolutely nothing gets cut off, no matter the device. However, for 2026 standards, the 1546x423 area is officially supported by YouTube's current guidelines.
