twelve basic characteristics for comparing handwriting

Experts usually examine the following characteristics when examining handwriting samples:
1. Line quality: Do the letters flow or are they written with very intent strokes?
2. Spacing of words and letters: What is the average space between words and letters?
3. Ratio of height, width, and size of letters: Are the letters consistent in height, width, and size?
4. Lifting pen: Does the author lift his or her pen to stop writing a word and start a new word?
5. Connecting strokes: How are capital letters connected to lower-case letters?
6. Strokes to begin and end: Where does the letter begin and end on a page?
7. Unusual letter formation: Are any letters written with unusual slants or angles? Are some letters printed rather than in cursive?
8. Pen pressure: How much pen pressure is applied on upward and downward strokes?
9. Slant: Do letters slant to the left or right? If slant is pronounced, a protractor may be used to determine the degree.
10. Baseline habits: Does the author write on the line or does the writing go above or below the line?
11. Fancy writing habits; Are there any unusual curls or loops or unique styles?
12. Placement of diacritics: How does the author cross the t's or dot the i's?
