1 inch square or 24.5 mm square for people who use non-Imperial measure

25.4 mm side length would be the correct conversion for 1 inch.

I just measured from my 122 Model F and it was about 21mm squared.

I got a better scale and magnifying glass. The 24.5mm is about as close as I can get but the badge is really about 0.97 inch.

I am measuring a naked metal badge, not the space where it goes.

This is the one that says "Personal Computer" in small italics under the large IBM logo. I think it came from an XT.

The plain one from a 122-key terminal looks to be about 25/32" or 19.5mm square.
