Nib / X-height Consistency Checker
Check that repeated x-height measurements agree within tolerance under the stated rule: spread is (max-min)/mean in percent and the hand counts as consistent when spread does not exceed the tolerance (default 10%).
Description

Nib / X-height Consistency Checker: Check that repeated x-height measurements agree within tolerance under the stated rule: spread is (max-min)/mean in percent and the hand counts as consistent when spread does not exceed the tolerance (default 10%).
When to use Nib / X-height Consistency
Use this palaeographic utility to apply a stated dating, script, abbreviation, codicological, metrological, layout, or condition rule consistently while preparing manuscripts for scholarly review.
- X-heights
- Repeated x-height measurements of one hand in mm.
- Tolerance (%)
- Maximum allowed spread in percent.
How Nib / X-height Consistency works
Check that repeated x-height measurements agree within tolerance under the stated rule: spread is (max-min)/mean in percent and the hand counts as consistent when spread does not exceed the tolerance (default 10%). The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Mean x-height (mm)
- Arithmetic mean of the measurements.
- Spread %
- (max - min) / mean expressed in percent.
- Consistent
- True when the spread is within tolerance.
Limitations and assumptions
- Script and manuscript evidence varies by language, region, institution, period, scribe, material, restoration, and cataloguing convention. A heuristic flag or score is not an authoritative date, hand attribution, reading, provenance, or conservation diagnosis.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Retain page images, scale, foliation, material, provenance, diplomatic transcription, uncertainty, and comparison exemplars; confirm conclusions with codicological context and specialist judgment.

- Scribe Change Detector
Flag a possible change of scribe under the stated rule: each metric (line spacing, letters per line) is compared by the symmetric percent deviation |a-b|/mean(a,b)*100, and a deviation above tolerance (default 5%) on either metric flags a change.
- Carolingian Single-storey Flag
Flag a Caroline-minuscule-like script profile under the stated heuristic: a hand counts as showing the single-storey Caroline a profile when its single-storey a share reaches the threshold percentage (default 80).
- Chirograph Wavy-Cut Checker
Assess a cut-apart chirograph under the stated heuristic: halves whose surviving letter counts differ by no more than the tolerance count as matching when a wavy cut is visible, mismatched otherwise, and indeterminate whenever no wavy cut is visible.
