According to John Travis, "A Guide to Restringing", a Steinway Square Grand uses a unison of #23 wire.
A Kranich and Bach, Ser No 57389, has 4 unisons of #24.

  Basically, no where on a piano. At least that I know of. But that chart had several 
  sizes even larger than that!

      Michelle, 


      Dave beat me to it but here's a chart you might like to keep handy. 

      I have one similar hanging on a wall in my shop. I can also send it

      to in Excel if you can open that.

        That would be correct.  Wire that thick can have a mind of it's own!

        Iâ?Tm new at this game Avery so please tell me if Iâ?Tm wrong.  I just measured the scrap string I took off the piano at .041.  Am I correct that this would be a size 18?



        Itâ?Ts a giant old piano.



        Thanks!



        Michelle

        Wow. That seems awfully big for middle C. You sure it wasn't a lower note?
