Mostly about the appearance of letters-ex. slant or curve
Letter form includes shape of letters, curve of letters, the angle or slant of letters, the proportional size of letters, and the use and appearance of connecting lines between letters.
The first picture of handwriting shows proper use of cursive handwriting and it is an example of handwriting that would be very easily identified because it is unlike most other types.
The second picture shows handwriting is still very nicely written would be set apart from the handwriting above because of its fancy characteristics such as the loops and the crossing of the letter T.
In the picture below it shows very smooth letters with even darkness both on the upward and downward strokes. It shows that the person wrote slowly and carefully and with a ballpoint pen.
Formatting includes the spacing between letters, the spacing between words and lines, the placement of words on a line, and the margins a writer leaves empty on a page.
In the picture below it shows that the spacing between letters is uneven, for example "bad things" is much closer to each other than other words. The first line is further away from the second line. The writing slants downward as he/she wrote right to left. And he/she started further to the left on the first line that they did on the other lines.
