Why do beginners use the font size of the original post to get started? It is too big and too small.

Here are some points. First, if the handwriting is the same size as the original post, it is easier to compare after writing. Second, writing is too large, so it is not easy to write small, and there are also differences in writing skills (especially the use of wrists and fingers). Third, learn to master the existing materials, and it will be easier to write big or small words in the future.
