Materials and Methods: Ninety nine female Saudi subjects aged 18–35 were selected. Inter commissural width was measured directly on the participants of the study using digital caliper with precision of 0.01mm.Combined width of maxillary central incisors were measured indirectly on the cast with the help of dental floss and digital caliper.

Results: The mean values for inter commissural width and distance between the distal aspects of canines (combined width of maxillary anterior teeth) in females were 45.51mm and 49.81 mm. In addition, the correlation value between inter commissural width and the difference between inter commissural width and the distance between the distal surfaces of the canines in Saudi female participants was found to be statistically significant (r = 0.273, p-value = 0.018).

Conclusion: The findings of the study indicated that, to select the combined mesiodistal width of maxillary anterior teeth, inter commissural width of the required patient should be multiplied by 1.094.
