Text.fontSize

public int fontSize;

Description

The size that the Font should render at.

This is the size of the Font of the Text. Use this to fetch or change the size of the Font. When changing the Font size, remember to take into account the RectTransform of the Text. Larger Font sizes or messages may not fit in certain rectangle sizes and do not show in the Scene.

//For this script to work, create a new Text GameObject by going to Create>UI>Text. Attach the script to the Text GameObject. Make sure the GameObject has a RectTransform component.

using UnityEngine;
using UnityEngine.UI;

public class Example : MonoBehaviour
{
    Text m_Text;
    RectTransform m_RectTransform;

    void Start()
    {
        //Fetch the Text and RectTransform components from the GameObject
        m_Text = GetComponent<Text>();
        m_RectTransform = GetComponent<RectTransform>();
    }

    void Update()
    {
        //Press the space key to change the Font size
        if (Input.GetKey(KeyCode.Space))
        {
            changeFontSize();
        }
    }

    void changeFontSize()
    {
        //Change the Font Size to 16
        m_Text.fontSize = 30;

        //Change the RectTransform size to allow larger fonts and sentences
        m_RectTransform.sizeDelta = new Vector2(m_Text.fontSize * 10, 100);

        //Change the m_Text text to the message below
        m_Text.text = "I changed my Font size!";
    }
}
