1. What is the Cephalic Index?

The Cephalic Index is a measurement used in anthropology and medicine to classify human head shapes. It is calculated as the ratio of the maximum width of the head multiplied by 100 divided by the maximum length of the head.

2. How Does the Calculator Work?

The calculator uses the Cephalic Index formula:

Where:

• Head Width — Maximum width of the head (cm)
• Head Length — Maximum length of the head (cm)

Explanation: The formula provides a simple numerical value that helps classify head shapes into different categories.

3. Importance of Cephalic Index Calculation

Details: The cephalic index is important in anthropological studies, craniofacial research, and medical fields for assessing head shape variations and identifying potential abnormalities.

4. Using the Calculator

Tips: Enter head width and head length in centimeters. Both values must be valid positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What are the different cephalic index categories?
A: Typically classified as: Dolichocephalic (≤75), Mesocephalic (75-80), Brachycephalic (≥81).

Q2: Is cephalic index measurement accurate?
A: While useful for classification, it's a simplified measurement and should be interpreted in context with other cranial measurements.

Q3: When is cephalic index measurement used?
A: Used in anthropology, forensic science, pediatric development assessment, and craniofacial anomaly diagnosis.

Q4: Are there limitations to cephalic index?
A: Yes, it doesn't account for overall head size or three-dimensional shape variations, and cultural/ethnic variations should be considered.

Q5: How should head measurements be taken?
A: Measurements should be taken using calipers at the maximum width (eurion to eurion) and maximum length (glabella to opisthocranion).
