Connie-
Hi, I really don't know the answer to your question. I'd advise you to take a measuring tape.
Speaking of which, I had to take a measuring tape with me to measure some pots that I saw down in Homestead. (they are clay bulb pans and they were dirt cheap!!) The first time I bought from that place, I could have sworn it was a 6 inch pot but when I got home it was more like a 10 inch pot. I have VERY bad spatial perception.
I was out there in the heat measuring clay pots. Gosh, I'm such the orchid geek!
