To convert a women’s size 16 pants to men’s size, you typically subtract 21 from the women’s size.
So, a women’s size 16 would roughly be a men’s size 34.
This is because in general, men’s pants sizes are measured by waist circumference in inches, and women’s sizes are based on a different scale. Here’s a quick reference:
Women’s size 16 ≈ Men’s size 34 (waist size).
Keep in mind that sizing can vary by brand, so it’s always a good idea to check the specific sizing chart for the brand you’re buying from.
