The Tanner stage calculator is an experimental program designed to determine a person's stage of sexual development based on self-assessed physical characteristics. This tool is not a substitute for professional medical advice and should not be used to diagnose or treat any medical condition.
How to Use the Tanner Stage Calculator

Access the Tanner stage calculator on this website by clicking the link here.
-
Enter your age, gender, and self-assessed physical characteristics, including height, weight, and pubic hair growth.
-
Click the "Calculate" button to receive your personalized Tanner stage classification.
-
Interpret the results, keeping in mind that the Tanner scale goes from 1.0 to 5.5, with 5.0 representing adult development and above indicating additional development after height growth stops.
What Does the Number Mean?
The Tanner stage numbers correspond to the stage of sexual development as follows:
| Tanner Stage Number | Stage of Development |
|---|---|
| 1.0 | Childhood |
| 2.0 | Early青春期 |
| 2.5 | Mid青春期 |
| 3.0 | Late青春期 |
| 4.0 | Adult |

Are You Curious About What Each Stage Bring?
Each Tanner stage brings about significant physical changes, including:
- Stage 1: The beginning of childhood, during which height increases rapidly and reproductive organs mature.
- Stage 2: An age when pubic hair begins to grow in preparation for fertility.
- Stage 3: A period of rapid growth in height and increased body mass.
- Stage 4: A decrease in height growth and the end of the growth spurt.
- Stage 5: Full physical maturity, with adult reproductive organs and body shaping complete.
