How can I calculate the size of one line in a Text component? For example the height of the line “HOW DO I CALCULATE” or “HEIGHT” in the picture below.

I have tried using the line height and line spacing properties but that does not give me the correct answer.

var lineHeight = textComponent.font.lineHeight * textComponent.lineSpacing;

The answer is fairly straightforward:

        private float CalculateLineHeight(Text text)
        {
            var extents = text.cachedTextGenerator.rectExtents.size * 0.5f;
            var lineHeight = text.cachedTextGeneratorForLayout.GetPreferredHeight("A", text.GetGenerationSettings(extents));

            return lineHeight;
        }

This one work with other ui scale mode:

public static float CalculateLineHeight (Text text) {
		var extents = text.cachedTextGenerator.rectExtents.size * 0.5f;
		var setting = text.GetGenerationSettings(extents);
		var lineHeight = text.cachedTextGeneratorForLayout.GetPreferredHeight("A", setting);
		return lineHeight * text.lineSpacing / setting.scaleFactor;
}
