Embedded IE Text Size Too Small (or Large)

Ever notice the text or font in applications that use an embedded Internet Explorer just isn’t the right size?  Either too small or large?  I’ve encountered this in a number of apps including Microsoft HTML Help Control (for .chm files), Windows Live Writer, and others.

Since I couldn’t find the answer online, I used my MS resources to track down this issue.  It warrants a blog post to help anyone else investigating this.  What’s going on here is that there is a registry key that defines the default text size for IE6 and earlier.  IE7 kept the old key for embedded browsers but uses a new one for full instances of IE.  Some apps (like Product Studio, an internal MS app) change the regkey without setting it back.  The result is that embedded browsers across your PC now look wrong, and there isn’t an easy way to fix it since embedded browsers don’t usually present a text size option.

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\International\Scripts\3
Change IEFontSize to “02 00 00 00” for a Normal Font Size

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\International\Scripts\3]

Example of the CORRECT SIZE:

IE Font Size Small, AutoHotKeyHelp, Correct Size

Example of TOO SMALL:

IE Font Size Small, AutoHotKeyHelp, Too Small


Example of TOO LARGE:

IE Font Size Small, AutoHotKeyHelp, Too Large

    Thanks, Noah. I’ve needed this since IE7 came out.

    Thank you Noah!!  I was having a heck of a time trying to figure out why the fonts in Windows Live Writer were shrunk!  Figures that Product Studio would be the culprit …

  3. Thanks Noah! What a bummer for folks who don’t know how to do registry hacks, but nice info for the rest of us geeks! 🙂

    Hey Kevin,

    That’s why the ‘Download Reg Fix’ link is there, non-registry hackers can just click that, open it, and it’ll apply the fix.

    I used to think it was just a bug in one of my Winamp plugins till I noticed other programs malfunctioning similarly.

    Thanks so much for the fix!

    Thank you, thank you, thank you!!  No more squinting at an application I use daily that "suddenly" developed an inexplicable case of "Honey, I Shrunk the Fonts!"

    A better alternative: ChmZoomer from  http://www.goldgingko.com/…/index.htm

    ChmZoomer gives you handy full page zoom functionality in all other browser-based applications, such as Chm files, e-Books, RSS Reader and so on. That is just like in IE7/8.
