It measures 10 1/4″ rim to rim and 4″ deep. There is no pitting. The cooking surface is very slick. The only flaw (see pics) is that on the bottom of the oven, the Griswold logo has excess iron in the incised area. It is not uncleaned carbon…. Just a bad pour when originally produced. Other than that, it is a perfect oven. It sits relatively flat but has a little movement on a glass top stove. Maybe 2 inches but no real spin. It would be perfect on a gas or coil stove. Overall, this is an excellent example. I took many pictures in different lighting/angles to show the true condition of the pan. This oven was cleaned to bare iron with electrolysis and seasoned 4 times and is ready to use right away.
