Designers should use a variety of fonts and sizes, especially when designing for a website, says Jennifer Tompkins, associate professor of marketing at the University of South Florida.
For an email newsletter, she recommends using the following fonts: Courier New, Courier, Helvetica, Times New Roman, and Sans Serif.
If you’re looking for something more specific, she suggests using a larger font, such as a Times New Gothic or Times Modern, or using a sans-serif typeface like Helvetique or Arial.
The same goes for your branding and design elements, such in how they’re designed, she says.
