Increasing a font's weight can make the text appear bolder and more prominent. It can help draw attention to the text and make it stand out on the page. It can also make the text easier to read, especially in smaller sizes or on screens with lower resolution. Additionally, increasing a font's weight can convey a sense of importance, strength, or emphasis in the message being communicated.
