Loose font refers to a type of font that has a more casual and informal appearance compared to formal fonts such as serif or script. These fonts often have a less structured or rigid appearance, with uneven lines and varying widths. Loose fonts can be used to convey a sense of playfulness, creativity, or informality in design projects such as posters, invitations, and social media graphics. There are various types of loose fonts available, including handwritten, brush and graffiti styles. These fonts can be great to use when you want to add personality and character to your design work.
