What "grower" and "shower" really mean
A "grower" looks modest soft and expands a lot when erect. A "shower" looks big soft and gains comparatively little. Most men sit somewhere in the middle. It's a description of change, not a grade — and it says nothing about how big you end up where it counts.
How the ratio is calculated
We divide your erect length by your flaccid length. A ratio around 2× or more leans grower; around 1.35× or less leans shower; in between is the crowded middle, where the population average lands. Flaccid length swings with temperature, stress and time of day, so treat the label as fun, not a verdict.
So which is "better"?
Neither. Erect size is what matters for sex, and flaccid size barely predicts it — see why flaccid size tells you almost nothing. For your actual percentile, run the main calculator.
