Head size as expressed by the cranial module averages 157.7 mm. for all Fijians. Regional fluctuation is unimportant.
Minimum Frontal
| No. | Range | Mean | S.D. | C.V. | |
| Total sample | 815 | 99-125 | 109.9 | 4.0 | 2.7 |
| Interior | 154 | 100-121 | 109.8 | 3.6 | 3.3 |
| East | 120 | 99-122 | 110.8 | 3.8 | 3.4 |
| Coast | 210 | 100-125 | 109.7 | 4.7 | 4.3 |
| N.W. | 79 | 101-120 | 109.4 | 3.7 | 3.4 |
A minimum frontal diameter of 109.9 mm. indicates a fairly ample forehead breadth for the total sample. None of the subgroups depart much from this value.
Fronto-Parietal
| No. | Range | Mean | S.D. | C.V. | |
| Total sample | 815 | 58-89 | 70.6 | 4.3 | 6.1 |
| Interior | 154 | 63-82 | 72.2 | 3.3 | 4.6 |
| East | 120 | 64-79 | 70.5 | 3.0 | 4.3 |
| Coast | 210 | 58-77 | 69.9 | 4.1 | 5.9 |
| N.W. | 79 | 61-89 | 69.7 | 8.7 | 12.5 |
Forehead breadth relative to total cranial width is 70.6 per cent. The greatest deviation from this average occurs in the interior where the fronto-parietal ratio is 72.2 per cent and lesser head breadth more than greater forehead width causes the higher index.
