Protofo-BoldItalic

Protofo Bold Italic font by Lafontype is a free humanist sans serif font that hits the sweet spot between geometric precision and easy, conversational warmth. Its bold weight and forward-leaning stance add momentum to text, while the soft curves and open shapes keep everything highly readable on screens and in print. As part of the wider Protofo family, it drops effortlessly into systems where you need clear hierarchy and consistent voice.

Using Protofo Bold Italic, you get a go-to style for app interfaces, buttons and CTAs, tech branding, editorial subheads, web banners, and punchy social graphics. The italic angle injects energy without shouting, making emphasis feel intentional rather than loud. This free font pairs naturally with lighter Protofo weights for body copy—set Bold Italic a size or two larger to create crisp, confident headings that still feel approachable.
