How to Use the YouTube Video Preview Tool
Choose Your Preview Mode
Switch between Grid Card (how your video looks on the YouTube homepage or search results) and Watch Page (the full player + metadata layout).
Enter Your Video Title
Type your video title and watch the character counter. YouTube shows roughly 60-70 characters before truncating, so this helps you write click-worthy titles that don't get cut off.
Upload Your Thumbnail
Upload your 1280×720px thumbnail image. It renders in both the grid card and watch page views so you can check it looks compelling in both contexts.
Set Channel Details
Enter your channel name, subscriber count, and whether your channel is verified. These populate both preview modes accurately.
Adjust Views, Likes & Duration
Set the video duration (appears on thumbnail corner), view count, and like count using sliders and text fields to complete the realistic mock-up.
About This Tool
The YouTube Video Preview Tool helps creators, marketers, and editors see exactly how a video listing will appear on YouTube — before uploading. Both the grid card (homepage/search) and full watch page layouts are simulated.
Your thumbnail and title are among the most critical factors in a video's click-through rate. Testing different combinations before publishing gives you a significant advantage. You can also use this tool to present video concepts and planned thumbnails to clients for approval.
