The YouTube banner problem

YouTube channel art is a 16:9 image, but most devices only show a thin strip in the middle — on a phone, roughly the central 1546 × 423 pixels of a 2560 × 1440 banner. A photo resized to fit that strip leaves the rest of the banner empty; a photo resized to fill the whole banner gets its important part cut off.

Here your photo is fitted where you place it and the rest of the 16:9 canvas is extended to match. The dashed box shows the area that stays visible everywhere — keep faces and logos inside it.

Sizes

2560 × 1440 is the recommended size; 2048 × 1152 is the smallest YouTube accepts, with a 1235 × 338 safe area. Sizes are as YouTube published them in October 2026 — check YouTube Help before an important upload. YouTube also asks for 6 MB or less: choose JPG at High quality.

Questions

What size is a YouTube banner?

YouTube recommends 2560 × 1440 pixels (16:9), with a minimum of 2048 × 1152. The always-visible safe area at the minimum size is 1235 × 338 pixels in the centre.

How do I make my photo fit the banner without cropping?

Open it here; it's fitted into 2560 × 1440 and centred on the safe area. Use Photo size in the frame to make it smaller, drag it to position, and the empty sides fill to match.

Can I make a YouTube thumbnail too?

Yes — under YouTube choose YouTube thumbnail (1280 × 720).

Is my photo uploaded anywhere?

No. The photo is opened, extended and saved by this browser tab. The only optional downloads are the AI models, which are plain files coming to you — nothing about your photo goes out.
