These logos are built entirely of the word or words that make up the company’s name. The main focus here is typography, obviously. This style of logo strongly ties a brand’s visual identity to the name of the company.
A monogram is a logo that contains one to four letters, usually a company’s initials or first letter. It’s used instead of a traditional symbol, turning a company’s identity into an eye-catching visual.
A wordmark or lettermark with a symbol (often called a logomark) is what makes up a combination logo. It’s the most common type of logo design, in part due to its flexibility. You can use the symbol on its own (e.g. in social media profile photos or favicons), or just the wordmark or lettermark when you need it.
One of the oldest forms of a logo is the emblem. Simply put, it’s text inside of a symbol, often a circle or other shape, with curved text and a vintage feel — think of badges, seals or crests. This logo is treated as a cohesive image, rather than typography.
