May I suggest  different font if your website is having a rehaul? From a professional point of view, and quoted from one of the top designers in Australia whom I met and worked with, "Arial is not a font." There are much better formed and more precise corporate fonts out there. I don't want to come across as a know it all, but its just something to think about. I know where your coming from though, its an easy font to use, and it's on every computer. There are other common corporate fonts that have better and more even form within the letters.

Kind Regards

Stuart
