YouTube Image Sizes

YouTube uses three primary image surfaces: video thumbnails, the channel banner, and the profile picture. Each has tight specs because YouTube re-displays them across phones, TVs, tablets, and embedded players where bad sizing breaks visibly.

YouTube image strategy

Thumbnails are 1280×720 (16:9), capped at 2MB. Larger files get rejected outright. The thumbnail is the single biggest CTR lever on YouTube — high contrast, large faces, and minimal text (3-5 words max) consistently outperform busy designs. Test variants on the same video using YouTube's built-in A/B testing. The channel banner is 2560×1440 (16:9) but appears differently on every device. The "TV-safe area" is the centre 1546×423 — anything outside that gets cropped on desktop, mobile, or TV depending on the device. Treat the centre band as the only reliably visible area; treat the rest as decorative. Profile pictures appear as 800×800 source but render at 98×98 in headers and 24×24 in inline mentions. Simple, high-contrast designs survive the downscale. Avoid fine detail, tagline text, or multi-element compositions — none of those read at 24×24. YouTube re-encodes thumbnails for different surfaces (search results, suggested videos, embeds). The re-encode is noticeably more aggressive than Instagram or Facebook, so start with a sharp, high-contrast source — fuzzy or low-contrast sources degrade visibly after re-encode. For end-card and watermark overlays inside videos, YouTube recommends 800×800 PNG with transparency. The watermark scales down to about 150×150 in the bottom-right corner of every video.

YouTube sizing FAQ

What size should a YouTube thumbnail be?▼

YouTube thumbnails should be 1280×720 pixels (16:9), under 2MB, in JPG, GIF, or PNG. Anything outside these specs gets rejected at upload. Always design at 1280×720 — designing larger and downscaling can lose detail you wanted YouTube to see.

What is the YouTube banner size?▼

YouTube channel banners are 2560×1440 pixels (16:9). The TV-safe area is the centre 1546×423 — keep all important content within that band. The rest of the banner gets cropped differently across desktop, mobile, and TV.

What size is a YouTube channel profile picture?▼

Upload at 800×800 pixels minimum. The picture displays as a circle at sizes from 98×98 (header) down to 24×24 (inline mentions). Design for legibility at the smallest size.

Why does my YouTube thumbnail look pixelated?▼

Either your source was under 1280×720, or YouTube re-encoded a low-contrast or noisy source. Always design at exactly 1280×720, use high contrast, and avoid noise or grain in the source image.

Are PNG thumbnails better than JPEG on YouTube?▼

PNG preserves text sharpness but produces larger files. JPEG at 90% quality is usually within YouTube's 2MB limit and survives the re-encode equally well for typical thumbnail content (faces, gradients, large text). Use PNG only when you have sharp text or a logo over a flat colour.
