You can learn a great deal about a page of handwriting without claiming to know the person who wrote it. You can describe the size of the letters, the distance between words, the angle of the downstrokes, the baseline, the margins, and the forms that belong to a particular school model. Those observations are useful for comparison, teaching, archival description, and design.
This guide shows how to make them in a repeatable order. It also marks the point where description usually turns into unsupported inference, so you can stop before a measurement becomes a personality verdict.
1. Prepare a fair sample
Use ordinary writing, not a signature and not a carefully copied quotation. A signature is a practiced display form; a copied passage may be slower and more formal than everyday writing. Three or four lines of something you wrote without thinking about being analyzed are more representative.
Use the pen and paper you normally use. A fountain pen on smooth paper produces different lines from a ballpoint on a rough notebook, and a tablet produces no ink at all. Note the conditions: pen type, paper, whether you were standing, and whether the page was on a hard surface.
If you are comparing two samples, keep the conditions as similar as possible. A change in pen can change the apparent size, spacing, and slant. If the conditions differ, describe them before you describe the writing.
2. Describe size and proportion
Measure the height of a lowercase x-height, not the tallest ascender. The x-height is the body of a letter such as a, c, e, or o. Compare it with the line spacing and with the width of the letters. A page can have large letters and tight line spacing, or small letters with generous space.
Size is relative. A page written on a small notepad may look large when photographed, and a page written on A4 may look small. If you need a number, measure the x-height in millimetres and record the paper size. If you only need a description, use terms such as compact, moderate, or expansive, and say what you are comparing.
Proportion matters more than a single height. Are ascenders and descenders long relative to the x-height? Are the letters wide or narrow? Is the writing crowded at the top of the line or the bottom? Those relationships survive a change of paper better than absolute size.
3. Describe spacing and baseline
Look at three gaps: between letters, between words, and between lines. Letter spacing is often called tracking in typography; in handwriting it varies with speed and with the writer's model. Word spacing is easier to judge relative to the width of an average letter than in millimetres.
The baseline is the invisible line the letters sit on. Does the writing stay level, drift upward, drift downward, or wave? A drift can be caused by the page angle, the writing surface, or the writer's arm position. It is not a mood ring. Describe the drift, then look for a mechanical explanation.
Margins are part of the layout. A narrow left margin may mean the writer started at the edge of the page; a wide right margin may mean the page was rotated. Before reading a margin as a choice, check whether the paper or the writing surface constrained it.
4. Measure slant
Slant is the angle of a downstroke from vertical. Choose a straight stem, not the curved side of a letter. Align a ruler or the slant tool with the middle of the stroke and read the angle. Take three readings from different lines and report the range.
A photo can distort the angle. Keep the camera square to the page and avoid the corners of the frame. If you are comparing pages, use the same camera position and the same kind of paper. A change of 10 degrees between two pages may be a real change in the writing or a change in the photograph.
For a quick description, use left of vertical, near vertical, and right of vertical. For a comparison, record the degrees. The exact number is more useful than a trait word, and it is easier to check.
5. Describe letterforms
Pick a small set of forms that vary visibly: 4, 7, a, g, t, i, y, and the ampersand. For each, decide which form is closer. Is the 4 open or closed? Is the 7 crossed? Is the a single-storey or double-storey? Is the g looped or open? Where is the t crossed? Is the i dotted, undotted, or circled?
Name the form without explaining the person. 'Closed 4' is an observation. 'Perfectionist' is an inference. The first can be checked by another person; the second cannot. If you want to go further, ask where the form is taught and whether the writer uses it consistently.
Consistency is a useful description. Does the same form appear on every line, or does it change with speed? A writer may use a closed 4 in a careful note and an open 4 in a hurried one. That variation is a fact about the page, not a contradiction in the personality.
6. What you cannot see in a photo
A photo records ink, not pressure. A dark line can come from a soft pencil, a wet pen, or a heavy hand. Without a known pen and paper, you cannot separate those causes. Do not describe pressure from a photograph unless you have a controlled sample and a reason to trust the comparison.
A photo also loses speed and stroke order. You can sometimes infer that a line was written quickly from its smoothness, but you cannot measure speed without a process recording. If speed matters, use a digitizing tablet or a video. Even then, the measurement describes the task and the device as much as the writer.
Erasing, retracing, and correction are visible, but their meaning is not. A crossed-out word may be a change of mind, a slip of the pen, or a deliberate edit. Describe the mark; do not turn it into a character trait.
7. Keep observation and inference separate
A useful analysis has two columns. The left column contains what you can point to: 'x-height 2.5 mm', 'word gaps about one letter wide', 'stems lean 12 degrees right', 'closed 4 on all four lines'. The right column contains what you are tempted to conclude. Keep the right column empty unless you have evidence that the conclusion follows.
The evidence for graphological inferences is weak. A meta-analysis by Neter and Ben-Shakhar (1989) found near-zero validity for graphologists' predictions in personnel settings when the text was neutral. That does not mean no one can ever learn anything from handwriting; it means the specific claim that a stroke reveals a stable trait is not well supported.
You can still use handwriting analysis for description, comparison, teaching, and document study. Those uses do not require the personality leap. If you are writing about a historical figure, say what the page shows and what it does not. If you are teaching, ask students to compare forms and explain the model behind them.

Questions
- How do you analyze handwriting?
- Start with a fair sample, then describe size, spacing, baseline, slant, and letterforms. Keep observations separate from personality inferences, and note the pen, paper, and conditions.
- What does handwriting analysis reveal?
- It can reveal the forms a writer uses, the layout of a page, and some measurable features such as slant and spacing. It does not reliably reveal personality, intelligence, or honesty.
- Should I use a photo or a scan?
- A flat scan is usually better for measurement because the page is square to the sensor. A photo is acceptable if the camera is directly above the page and the writing is not near the edges.
- How do I measure handwriting slant?
- Align a ruler or the slant tool with the straight part of a downstroke and read the angle from vertical. Take three readings and report the range.
- What is a good handwriting sample?
- Three or four lines of ordinary writing on unlined paper, using your normal pen. Leave out the signature and avoid copying a printed model.
- Can handwriting show stress or illness?
- Handwriting can change with fatigue, medication, injury, and neurological conditions, but changes are not a diagnosis. A clinician assesses health, not a letterform.
- Can I use this method to compare two people?
- You can compare descriptions of two samples, but you cannot identify a person from them. Forensic document examination is a separate, trained discipline with its own limits.
