I had noticed this early on too and I think anything less than 50 or 52 did it on mine. I'd guess Android uses a weird 9 Patch with too much margin area. All my apps now use my View Manager Class that I made my own 9 Patch for that looks like Windows 9x Textboxes. The class automatically sizes to fit the font size, but when I use a size 5 font the view is 21 pixels tall and still shows right, so Android's 9 Patch needs some work.
