YouTube thumbnails are your video's first impression. Using the right dimensions and following design best practices helps your videos stand out and get more clicks.

YouTube Thumbnail Dimensions

Official Requirements

Recommended Resolution: 1280 x 720 pixels Minimum Width: 640 pixels Aspect Ratio: 16:9 Maximum File Size: 2MB Accepted Formats: JPG, GIF (non-animated), PNG, BMP

Why 1280 x 720 Works Best

This resolution:

YouTube Shorts Thumbnail Size

Shorts Specifications

File Size Guidelines

Under 2MB Required Keep files small without losing quality:

Color Space and Quality

Use RGB Color Mode

Contrast is Key:

Text Placement:
