Default [Q] Setting Default Font Size in ROM Build

Where would I find the file that contains the default font size information. I'm building my own ROM and have changed the default font type but would like to set the default size of the font at time of install to the smallest possible size but have not been able to locate the file to do so. I've spent several hours looking through framework-res.apk and twframework-res.apk. I'm sure their in there somewhere and before spending more time looking for it, thought I would ask. Appreciate any help that could point me in the right direction. Thanks.
