Shirorekha
Definition
The horizontal headline stroke at the top of most Devanagari consonant characters, joining adjacent letters; its individual variation in height, pressure, continuity, and terminal treatment is the primary individualising feature in Hindi/Marathi/Nepali handwriting examination.
- Position
- Horizontal stroke across the top of Devanagari consonants
- Function
- Joins adjacent letters into a visually continuous word
- Individualising features
- Height, pressure, continuity, and terminal (start/end) treatment
- Scripts affected

Common questions
Why does the shirorekha matter so much in Devanagari handwriting comparison, more than in Latin script analysis?+
Latin cursive has no single continuous stroke shared by every letter in a word, but the shirorekha runs across nearly the whole word in Devanagari, so its habitual height, pressure, and breaks give an examiner a single, repeatedly sampled feature to compare across a large body of writing, functioning similarly to how baseline and slant are used in Latin script.
Can a forger disguise handwriting simply by altering the shirorekha?+
Altering it alone rarely defeats examination, because the stroke's habitual pressure pattern and connection points tend to persist even when a writer consciously changes its height or slope, and an examiner compares it alongside letter formation, spacing, and other features rather than in isolation.
