Please unzip the file.There is only one Slide and one TextFrame in it.You can see the font size is 36 which show in the toolbar.
MathPortion-Fontsize.pptx.zip (44.5 KB)
When I read the MathPortion’s font size, I get 18, Not 36.So I think I need some help.Any help would be grateful.

Thank you for the issue description. I reproduced the problem with the font height of the MathPortion objects and logged the issue with ID SLIDESJAVA-38614 in our tracking system. Our development team will investigate this case. You will be notified when the problem is fixed.

@oscarstar,
With Aspose.Slides for Java 23.5, please use the following code example:

Presentation pres = new Presentation("MathPortion-Fontsize.pptx");
try {
    ISlide slide = pres.getSlides().get_Item(0);
    IAutoShape shape = (IAutoShape)slide.getShapes().get_Item(0);
    for (IParagraph paragraph : shape.getTextFrame().getParagraphs())
    {
        for (IPortion portion : paragraph.getPortions())
        {
            if (portion instanceof MathPortion)
            {
                MathPortion mathPortion = (MathPortion)portion;

                for (IMathBlock mathParagraph : mathPortion.getMathParagraph())
                {
                    for (IMathElement mathElement : mathParagraph.getChildren())
                    {
                        if (mathElement instanceof MathematicalText)
                        {
                            MathematicalText mathText = (MathematicalText) mathElement;
                            IPortionFormatEffectiveData format = mathText.getFormat().getEffective();
                            System.out.println(format.getFontHeight());
                        }
                    }
                }
            }
        }
    }
}
finally { if (pres != null) ((IDisposable)pres).dispose(); }
