Rear Emblem for 2008 Corolla

Can anyone tell me what is the size (in inches) of the rear emblem on a 2008 Corolla? I think it is either 3.5inch or 3.75. I just need to be sure when I order on off EBay.
In case anyone is interested, I am working with a company to design these LED light kits called Lo-Glows that illuminate the Toyota badge from behind. Their website is This is why I need to buy the right size emblems.
