Cloth Napkin Size

[robbie3982]

Does anyone know what the dimensions of a typical cloth napkin are? While I was unable to sleep last night I came up with the idea of using a colored cloth napkin spread out in the center of the tables under the centerpieces to add something to them, but I can''t seem to find how big a napkin actually is.

A full size dinner napkins is 20" square.
