The size is a setting in the conversion software. You can choose
whatever size you want.  The reason you are getting a large result is
because the conversion tool you are using is defaulting to that target
quality of bitrate.

Of course, the quality is always going to be worse than the h264 file
because you are converting from one lossy format to another.

Have bugs been filed for Theora output for whatever tools you tried
using?   If you'd like I can help you off-list in getting them filed.
