Sixty-two vinyl polysiloxane casts from subjects in the lying, supine position were measured for surface area with five shapes: conical, parallel sides, heart, slug, and pumpkin seed being included. The surface areas ranged from 65.73 to 107.07 cm2 with a mean of 87.46 cm2 and a standard deviation of 7.80 cm2. There were no significant differences in surface area among the shape groups. And no correlations with surface area were found by parity or by rod length, introital diameter, posterior length of casts as measured with string, or greatest width and greatest depth of casts. 70% of the casts had a surface area of 84.50 cm2 or above, and 90% had a surface area of 77.72 cm2 or above. Variation within the interquartile range (75th to 25th percentile) was ±5.2% of the median.
