wire size

[pianotune05 at comcast.net]

Hi John,
I have special reading glasses for these, and I've seen one where the numerals weren't too bad.  I wanted to make certain that there weren't any out there that I was missing.  Thanks for the idea.  I need to get my hands on one.

They have digital readout micrometers, if the numerals are too small, a magnifying glass can be used.

Does anyone out there have any recommendations on a micromiter to measure wire thickness for those of us who are vision impaired.?  I have one of those round slotted kind, gray in color that you place over the string to see how think it is.  It's a little tough to read.

 Michelle,

A good way to remember without a chart:

Subtract 5 from the thickness, then divide by two, and voila!  The wire size  

(41-5+36, 36 divided* by 2 = 18)

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.

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

I’m new at this game Avery so please tell me if I’m wrong.  I just measured the scrap string I took off the piano at .041.  Am I correct that this would be a size 18?
 
It’s a giant old piano.
 
Thanks!
 
Michelle

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