Thai and East Asian Text and Font Sizing
Affected Internet Explorer Document Mode
- IE9 Standards
Feature Impact
- Severity: Low
- Probability of Impact: High
Description
Thai and East Asian text may look smaller in IE9 than in IE8 and earlier releases. In IE8, Thai and East Asian text could be rendered at a larger font size than specified when:
- The specified font size was 9pt or smaller
- The specified font family did not support Thai or East Asian characters such as Arial
Thus, a Thai paragraph of 8pt Arial would be rendered using the fallback font specified in Internet Options-Fonts and the latter would then be scaled up to match Arial metrics. As a result, the real size is larger than it would have been if the web author had requested that font at 8pt.
In IE9, the specified font size is always respected. Thus, as the fallback font is no longer scaled up, text may appear smaller.

Guidelines
When possible, make sure the first value of the CSS font-family property supports your language.
For instance, instead of asking for Arial, use MS PGothic. Instead of Times New Roman, use Mincho. Instead of Verdana, use Meiryo. You can use the Internet Options – Fonts dialog to check the default fallback mappings used by IE.
This will ensure your text renders using the specified font size in all versions and modes of IE.
