Fonts and typography have become significantly important as graphic designing forms an integral part of the marketing and advertising world. It takes a keen eye to understand which font looks good when paired with another and whether these different fonts need to have a different size. Unfortunately, this is where the most designers fall short and end up making a mistake.
The best idea is to choose the fonts that contrast. The thumb rule is this, either don’t use different fonts or use fonts that create a huge contrast. There is no in-between. Go big or go home, that’s the mantra for creating the perfect font contrast.
