This casserole is 12 inches across and 4.5 high. You can use it on top of the stove and in the oven to 400 degrees. I have used it less than six times. It's too big for two people. I bought it to make bread in. Good for stews etc. You can brown the meat on top of the stove and then transfer it to the oven. Both the casserole and lid are fine in the oven. Analon Umber comes with a lifetime warranty. Sorry there is a lot of reflection of my kitchen cupboards in the photos. I have bought a smaller version
