YouTube Banner Size, Thumbnail & Video Dimensions in 2026
The exact YouTube image sizes for channel banners, thumbnails, video uploads and Shorts. Avoid blurry uploads and cropped artwork.
YouTube Banner Size, Thumbnail & Video Dimensions in 2026
You spent an hour designing your YouTube channel banner, upload it, and half your text is invisible on mobile. Or your thumbnail looks perfect on desktop but turns into an unreadable blob on a phone screen.
YouTube displays the same image at wildly different crops depending on the device. If you don't design for the safe zone, you lose control over what viewers actually see.
Here are the dimensions that work across every device in 2026.
Quick Reference Table
| Format | Dimensions (px) | Aspect Ratio | Notes |
|---|---|---|---|
| Channel Banner | 2560 × 1440 | 16:9 | Full upload size |
| Banner Safe Zone | 1546 × 423 | ~3.7:1 | Visible on all devices |
| Thumbnail | 1280 × 720 | 16:9 | Max 2MB, JPG/PNG |
| Video (1080p) | 1920 × 1080 | 16:9 | Standard HD |
| Video (4K) | 3840 × 2160 | 16:9 | Best quality |
| Shorts | 1080 × 1920 | 9:16 | Vertical full-screen |
| Profile Picture | 800 × 800 | 1:1 | Displays as circle |
Channel Banner — The One Everyone Gets Wrong
The full banner size is 2560 × 1440 pixels, but that doesn't mean the entire image is visible. YouTube crops it differently on every device:
- Desktop: Shows roughly 2560 × 423 (a thin horizontal strip from the center)
- Mobile: Shows an even narrower crop, roughly 1546 × 423
- TV: Shows the full 2560 × 1440
The practical implication: your logo, channel name, and any text must fit inside the 1546 × 423 safe zone centered in the middle of your 2560 × 1440 canvas. Anything outside that zone will be cut off for the majority of your viewers.
A common mistake is putting social media handles or upload schedules near the edges. They show on your monitor but disappear on phone screens, which account for over 70% of YouTube watch time.
Thumbnails — 1280 × 720
Custom thumbnails are non-negotiable. YouTube's own data says 90% of the best-performing videos use them.
Requirements:
- Minimum resolution: 1280 × 720 (width minimum 640px)
- Aspect ratio: 16:9
- Max file size: 2MB
- Formats: JPG, PNG, GIF (no animated), BMP
For CTR, the thumbnail matters more than the title. Keep text large (readable at 100px wide, which is how it appears on mobile feeds), use high contrast, and include a face when possible. Faces with expressive reactions outperform text-only thumbnails consistently.
Video Upload Dimensions
YouTube accepts a wide range of resolutions, but these are the standard ones:
| Quality | Resolution | Use Case |
|---|---|---|
| 720p (HD) | 1280 × 720 | Minimum acceptable quality |
| 1080p (Full HD) | 1920 × 1080 | Sweet spot for most creators |
| 1440p (2K) | 2560 × 1440 | Higher quality, larger files |
| 2160p (4K) | 3840 × 2160 | Best quality, slow uploads |
Upload at 1920 × 1080 minimum. YouTube re-encodes everything anyway, so uploading at higher resolution gives the algorithm more data to work with. The difference between 1080p and 4K source footage is visible on large screens.
If you shoot vertically for Shorts, the resolution is 1080 × 1920 (same as Instagram Stories/Reels).
YouTube Shorts — 1080 × 1920
Shorts use the same 9:16 vertical format as Instagram Stories and TikTok videos. The upload requirements:
- Resolution: 1080 × 1920 (or any 9:16 ratio)
- Duration: Up to 3 minutes (changed from 60 seconds in 2024)
- File size: Standard video limits apply
One thing to know: when a Short appears on your channel page grid, it gets cropped to a taller thumbnail. Keep the key visual in the center vertical third.
Profile Picture — 800 × 800
Your profile picture displays as a circle everywhere on YouTube. Upload a square image (800 × 800 minimum) and make sure nothing important sits in the corners — they get clipped by the circular mask.
The profile picture appears tiny in most contexts (comments, suggestions sidebar), so use a simple image with high contrast. Detailed photos or small text won't be legible at 40×40 pixels.
How to Resize Images for YouTube
If your existing images don't match these dimensions, the fastest fix is to resize them before uploading:
- For banners: Use a free image resizer with the YouTube Banner preset (2560 × 1440)
- For thumbnails: Resize to 1280 × 720 keeping 16:9 ratio
- For Shorts covers: Use the same 9:16 format as Instagram Stories — an Instagram photo resizer works identically for Shorts
The key is resizing before upload rather than letting YouTube compress and crop for you. YouTube's automatic processing prioritizes file size over visual quality, so pre-sized images always look sharper.
