YouTube Video, Shorts, Thumbnail & Banner Sizes: The Complete Reference
YouTube looks like one platform, but as a creator you're actually designing for at least four different canvases: the video player, the Shorts feed, the thumbnail grid, and your channel page. Each has its own ratio, resolution, and quirks. Here's every number you need, plus the reasoning behind them so the specs actually stick.
Standard videos: 16:9, always
The YouTube player is built around 16:9. Videos in other ratios still play, but the player pads them with bars, so exporting at 16:9 is almost always the right call for regular uploads. The standard resolution ladder:
| Name | Resolution | Notes |
|---|---|---|
| 480p (SD) | 854×480 | Minimum acceptable quality today; note 854 is a rounding of 853.33 |
| 720p (HD) | 1280×720 | YouTube's minimum bar for the "HD" badge |
| 1080p (Full HD) | 1920×1080 | The practical default for most creators |
| 1440p (2K/QHD) | 2560×1440 | Triggers YouTube's higher-bitrate VP9 encoding — a popular quality trick |
| 2160p (4K/UHD) | 3840×2160 | Future-proof; large files, slower uploads |
The 1440p trick: many creators upload 1080p footage upscaled to 1440p or 4K. Higher resolutions get processed with a better codec and higher bitrate, so even viewers watching at 1080p may see a cleaner image. It costs upload time but nothing else.
Shorts: vertical 9:16
Shorts use 9:16 — the same numbers as regular video, rotated. Export at 1080×1920. Videos must be 3 minutes or less to qualify as a Short. Square (1:1) footage is also accepted and gets padded, but full-frame vertical performs visibly better in the feed since it fills the entire phone screen.
Design caution: the Shorts interface overlays the title, channel name, audio attribution, and action buttons over the video itself — the bottom ~20% and right edge are partially covered. Keep captions and key visuals in the center of the frame.
Thumbnails: small canvas, big consequences
Thumbnail spec: 1280×720 (16:9), under 2MB, in JPG, PNG, or non-animated GIF format. The minimum width YouTube accepts is 640 pixels.
What the spec sheet doesn't tell you: most impressions happen at tiny rendered sizes — roughly 160–360 pixels wide on phones and in sidebars. That means:
- Text needs to be enormous relative to the canvas — think 3–6 words maximum.
- The bottom-right corner is covered by the duration badge; keep it clear.
- High contrast between subject and background matters more than fine detail.
Channel banner: one image, three crops
The channel banner is the trickiest asset because a single upload is cropped differently on TV, desktop, and mobile:
| Area | Dimensions | What it's for |
|---|---|---|
| Full upload | 2560×1440 | What TV apps display — the entire image |
| Desktop visible | ≈2560×423 | The horizontal strip desktop browsers show |
| Safe area | 1546×423 | The center zone visible on every device — put all text and logos here |
Rule of thumb: design at 2560×1440, but treat everything outside the central 1546×423 rectangle as decorative background that may be cut off.
Profile picture
Upload at 800×800 (1:1). It's displayed as a circle everywhere, so keep the important content inside the inscribed circle — corners are always cropped away.
Quick answers
- Can I upload vertical video as a regular (non-Shorts) video? Yes — the player adapts, but on desktop it will show large pillars. Over 3 minutes, vertical uploads are treated as regular videos.
- Does YouTube re-compress my upload? Always. That's why uploading at higher quality than strictly necessary tends to pay off.
- What if my source footage is 4:3? Upload as-is; YouTube pillarboxes it cleanly. Don't stretch it to 16:9 — distortion looks far worse than bars.
