Today I wanted to show a picture comparison of the sizes:
You will notice I only have a picture of the larger Diva cup.
According to the Diva website both the Model 1 and Model 2 Diva cups are 57 mm tall and differ in diameter only.
for the Diva the sizing is:
The Model 1 cup is 1 11/16" (~4.3 cm or 43 mm) in diameter and the Model 2 cup is 1 13/16" (~4.6 cm or 46mm) in diameter. Both cups are approximately 2 1/4" (~5.7 cm or 57mm) in length in the body of the cup, with another 3/8" (~1 cm) stem (2 5/8" total length). The stem may be trimmed to adjust for comfort.
for the Lunette the sizing is:
Model 1: The diameter is 41 mm (1.6 inches) by 47 mm (1.9 inches). The stem measures 25 mm (1 inch). The volume of the cup is 25 ml (0.85 fl oz).
Model 2: The diameter is 46 mm (1.8 inches) by 52 mm (2 inches). The stem measures 20 mm (0.8 inches). The volume of the cup is 30 ml (1.0 fl oz).
