finally one I can answer .... using "very near" calipers, the overall height is 1" and the overall width is 2" for each letter ..... I say "overall" because the edges are bevelled (in at top - didn't measure this) .... measurements taken from original letters in great condidtion ..... actaully, I took several measurements and all where within +/- .010" of above stated dimensions .... hope this helps ....
