MS Word adds extra line spacing for asian fonts

Hi,

I found that MS Word is adding extra line spacing for Asian fonts  compared ti e.g. Windows Wordpad.

For example for font Gulim I see line heights are 13% higher than usual (defined by the font / GDI), for MS Gothic font I even see 30% extra spacing, for MingLiU only 8%.

For latin / other language fonts I do not see this behaviour. For them the font height provided by Windows GDI matches the line height in MS Word.

Does anybody know how Word decides how much extra line spacing is added for a font?

I need to predict the line heights, so I would know how Word decides how much extra space is added.

Thanks,

Christian

    I noticed a very strange behaviour when rendering asian fonts (compared to GDI):

    • MS Word adds extra line space
    • Windows Wordpad ommits the line space completly

    It occurs in all current Word versions starting Word 2007. I don't know if it already occured in Word 2003 (since it is out of support I cannot test). I tested on different machines using different Word (2010-2016) and Windows (7-10 / 2008-2016) versions.

    The issue I see only occurs for asian (Korean, Japanese, Chinese) fonts. I just compare how Wordpad displayes a test in the font with Word.

    In my tests it varies as said from 8% to 30%.

    Let me give you these examples:

    Korean font Gulim in 10 pt size

    has a GDI line height of 11.5pt but Word uses 13.0pt

    Japanese font MS Gothic in 10 pt size

    has a GDI line height of 10.0 but Word uses 12.95pt

    Microsoft JhengHei font in 10 pt

    has a GDI line height of 12.7pt but Word uses 13.3pt

    Yu Mincho font in 10pt size

    has a GDI line height of 16pt but Word uses 16.7pt

    SimSun font in 10pt size

    has a GDI line height of 11.4pt but Word uses 12.95

    Microsoft YaHei font in 10pt size

    has a GDI line height of 12.95 but Word uses 17.2pt

    these differences do not occur with latin fonts like Arial, Calibri, Tahoma, Times New Roman ...

    It probably makes sense and makes the document more readable. I would just be interested, or would need to know, how Word decides how much extra space is added.

    Regards,

    Christian
