Look in your stylesheet (the template area of your blogger blog) to find instances of font-size:. If the font size is in pixels (for instance: 11px), chances are that it is too small. The real disadvantage to pixel for font-size is that IE viewers cannot resize the text in their browsers.
Please use relative sizes instead of pixels for font-sizes!
Or if you really want to specify the font-size, choose to use em. That way even IE browsers will be able to adjust the size of font.
For more information on this, take a look at:

- How to size text using ems (www.clagnut.com/blog/348/)
Just remember that not everyone can read tiny fonts easily. Be kind to your shortsighted viewers.
