What is the most commonly used English font in America?

This is suitable for people

We have learned a font since the first grade, and most people are used to it when they grow up, Zaner-Bloser. And this font is very suitable for left-handed people. I am always laughed at by my friends in China. Zaner-Bloom is the surname of two Americans. Zaner is Charles paxton Zaner and Bloom is Elmer Ward Bloom. Zaner established a calligraphy school in Columbus, Ohio in the middle and lower levels of the18th century. /kloc-At the end of 0/8, Zaner cooperated with Bloser, who is not only an old classmate of Zaner, but also a highly skilled calligrapher. So Zaner-Bloser came into being and began to sell Zaner-Bloser fonts and their English calligraphy materials. This font was later popular in the United States, so you can buy their book Zaner's Method of Arm Movement for reference.
