Prepare a landscape thumbnail, vertical Shorts artwork, and a channel banner without losing the important details.

Leave room for the crop.

Use a 16:9 thumbnail composition for a standard video. Channel banners are cropped differently on TVs, desktops, and phones, so keep the name and essential branding within the central safe area. A Shorts cover can display differently from a regular video thumbnail.

Work from a high-resolution original and keep important text away from the edges. Cropping changes the framing; resizing changes the pixel dimensions. A larger export will not recover detail that is missing from the source.
