| Type | Width × Height | Aspect Ratio | Notes |
|---|---|---|---|
| Video Thumbnail | 1280 × 720 px | 16:9 | 16:9- max 2 MB |
| Channel Banner | 2560 × 1440 px | 16:9 | Safe area: 1546×423 px |
| Profile Picture | 800 × 800 px | 1:1 | Minimum 98×98 px |
Drop your thumbnail into ResizePack and choose the YouTube Thumbnail preset (1280×720 px, 16:9).
Thumbnails need strong contrast and readable text at small sizes- crop tightly around the subject using CropRatio at 16:9, then resize.
Keep the exported JPEG under 2 MB (YouTube's limit). Use the Compress tool to reduce file size if needed, then upload directly in YouTube Studio.

Use Batch Resize for batch resizing with social media presets, or Crop & Ratio to crop to the exact aspect ratio first.
1280×720 px in 16:9 ratio is the ideal YouTube thumbnail size. It is displayed at multiple sizes- from tiny grid previews to full-width suggestions. Maximum file size is 2 MB. YouTube accepts JPG, PNG, GIF, and WebP.
Upload your channel banner at 2560×1440 px. The safe area visible on all devices is the central 1546×423 px zone. Keep your logo and key text within that area to avoid cropping on TV, desktop, and mobile.
No. YouTube thumbnails must be 16:9 (horizontal). If your source image is portrait, use CropRatio to crop it to 16:9 first, then resize to 1280×720 px.
Use high contrast between the subject and background, a bold font for text overlays, and keep the most important element in the center-left third- that's where the eye naturally goes in thumbnail grids.
