Size labels are only the starting point. The Primal P185D comes in five options, so looking at the actual measurements is more useful than choosing by a letter alone.
Start with the Measurements
The table below follows the supplier’s size references. Total length includes the base. The average diameter is calculated from circumference, so it does not describe the widest point of the textured shape.
| Size | Total Length | Average Diameter* |
|---|---|---|
| XS | 14 cm | 4.8 cm |
| S | 16.5 cm | 5.7 cm |
| M | 19 cm | 6.8 cm |
| L | 22 cm | 7.8 cm |
| XL | 25 cm | 9.1 cm |
*Average diameter is estimated from the supplier’s circumference ÷ 3.14; it is not the maximum width. Total length includes the base, not just insertable length. Measurements are approximate.
Keep the Same Scale in Mind
Photography can make different sizes look similar. Use a ruler to understand the listed measurements, and compare dimensions rather than relying on image proportions.
Check the Selected Option before Checkout
Each size has its own price. Choose an option in the product selector, then confirm that the size and quantity in your cart match what you intended.
