He is a medium-height man.Is it correct ?
It's correct. However, it would be more common to say, "He is a man of medium height."
To determine whether the statement is correct, we need more information about what is considered medium-height. Generally, medium height can vary depending on cultural and regional factors. However, to get a better understanding, you can compare the person's height to the average height in their population or use standard height categories like short, medium, and tall.
If you have access to the person's height measurement, you can compare it to the average height for their age, gender, and geographical location. You can find average height charts or statistics online that can help you determine if someone's height falls within the medium-range.
Without specific measurements or comparative data, it's challenging to confirm if the statement is correct.
