1. Definition and measurement significance of uterine height
Uterine height is the vertical distance from the upper edge of the pubic symphysis to the base of the uterus. By measuring the height of the uterus, you can initially determine the development of the fetus, the amount of amniotic fluid, and whether there is an abnormal pregnancy (such as fetal growth restriction or macrosomia, etc.).
2. How to measure uterine height

2.Measure body position:Pregnant women need to lie flat with their legs straight and their abdomen relaxed.
3.Measurement steps:
- Locate the upper edge of the pubic symphysis (the lowest hard bone in the abdomen).
- Feel the fundus of the uterus (the hard edge at the highest point of the abdomen).
- Use a soft tape to measure the vertical distance between them.
4.Record data:Record the measurement in centimeters.
3. Normal range of uterine height
The height of the uterus increases with the gestational age and is usually consistent with the gestational age (within ±2cm is normal). The following are reference values for uterine height for each gestational age:
| Gestational age | Uterine height (cm) |
|---|---|
| 20 weeks | 18-22 |
| 24 weeks | 22-26 |
| 28 weeks | 26-30 |
| 32 weeks | 30-34 |
