Several font genres that fall within the regular font category influence display fonts design. These include script font, slab serif and sans serif. Because display fonts are used in headings, they can feature a wider range of designs. They simply aren't the same as other fonts that need to have high readability in a body of text. Display fonts are super popular with creatives like artists, crafters and printmakers. They are popular in projects like card-making, signwriting and the titles for eye-catching posters.
Display fonts draw on inspiration from a wide range of sources. They borrow from other lettering genres. Display fonts incorporate traditional calligraphy, vintage and hand-drawn signage. Display fonts are not good for text sizes that will appear under 14 points. Steer clear of display fonts if smaller text than 14 points is needed.
A great thing about display fonts is that they lend themselves fabulously well to unusual and eccentric projects. Anything that needs a decorative, ornamental or even exotic feel will suit a display font.
Display fonts can evoke some strong emotions. Think of old-fashioned circus and travelling fair signs. Artists, Etsy sellers and creatives might find that a display font works well for their product or brand image. Think of tattoo artists parlour signwriting and web presence, steampunk retailers and restaurants and bars with a nod to the Wild West.
