YouTube Watermark size at a glance
YouTube watermarks are small transparent overlays in the bottom-right of videos. They function as subscribe buttons when viewers hover over them.
Why 150×150 matters
A well-designed watermark is subtle branding that also drives subscriptions. It appears on every video automatically once set.
What happens when the size is wrong
Non-transparent backgrounds create an ugly opaque box over video content. Complex designs are unreadable at 150×150.
Best practices
- Use a simple logo mark with transparent background (PNG required).
- Keep it subtle — a large or busy watermark annoys viewers.
- Test visibility against both light and dark video backgrounds.
