I have a 10 inch pot. It measures 10 inches across the top of the pot(on the money).

I found my diameter tape measure. :thumbsup:

That same 10" pot (that says 10" on the sticker) measures 38 inches in diameter, using the diameter tape.

So a pot that measures to 8.5 inches in diameter is just over 2.75 inches across.

Edit,.. And I AM wrong.
