Ariali Thumbnail Font

Ariali is a bold sans-serif TTF font packaged inside a thumbnail font pack, which tells you exactly what it's for: big, readable headline text on YouTube and social thumbnails. At 0.6 MB it's a single lightweight font file, so installation is instant and it won't bloat your project. Bold sans-serif faces like this work best at large sizes where thick strokes stay legible even when the thumbnail is shrunk to a mobile feed. Use it for the 2-4 word hook on your thumbnail, and pair it with a contrasting lighter font for any secondary text so the hierarchy stays clear. Because it's a standard TTF, it installs system-wide and appears in the font menus of Photoshop, Illustrator, Premiere Pro, After Effects, DaVinci Resolve, Canva and CapCut. That makes it easy to keep the same look across your thumbnail, banner and video title cards.

How to use this resource

Install the TTF by double-clicking it and choosing Install (Windows) or adding it in Font Book (macOS), then restart your editing app. Select Ariali from the font menu and set your thumbnail headline in large caps with tight tracking. Add a stroke or drop shadow to keep it readable over busy backgrounds.
