Question: What is the inside diameter?
Document: It's a skillet... it's very small and holds an egg as I wanted it to. The surface for cooking inside isn't so great even with olive oil. I've only tried it once... it's ok.
This is a handy skillet for frying a single egg. It's billed as 5&#34; but the inside bottom is actually only 3.5&#34;. Also, the handle needs to be longer.
This cutey works especially well for deep frying one egg, but don't over-fill with oil or you'll have a dangerous spill. To be safe,  place it inside a larger frying pan.
But, if I'd known how LITTLE it really is, I would NOT have purchased it...I think that Amazon should make the seller RE-DO their description to say its true size OR specify that it is counting the two spouts as part of the 5" diameter...
I was very excited to get this mini skillet. However, even over low heat, it burned the food inside. I gently handwashed it as the instructions say to and it turned brown within minutes!
We ordered this knowing it was going to be small, but it looks like a toy. I uploaded a pic of the 5in inside of my 12in Lodge.Its a great little skillet to saute onions in for polish dogs or whatever..
The pan and matching lid (essential for even, thorough cooking) are superbly made in the USA out of quality cast iron. This pan is very small with the 5 inch diameter referring to the top of the pan. It is the perfect size for frying a single egg or making a mini frittata.
I have to agree with those who see this skillet as to small for much.I have found it useful for browning diced shallot and browning dicedgarlic. A single egg fits but the diameter of the skillet makes itdifficult to flip. The lid is heavier than the skillet but it isgood to use as mentioned previously. I also agree that it is a goodidea to re-season pre seasoned cast iron.
Five inches is the top diameter -- three inches is the bottom diameter. Too small for much of anything, but still, very cute. For those who are using these skillets in multiples to make individual pies, cobblers, or casseroles, I'd say it's a little expensive at this price to buy 6 or 8 -- why not just use Pyrex flan dishes or some beautiful Emile Henry mini-souffles? Cheaper and far easier to clean and maintain.
The pan itself is what it says it is EXCEPT FOR THE ACTUAL SIZE. To me, it is totally useless... I gave it to my daughter because she will use it to fry a single egg. It's not big enough for much else... The measurement of 5" includes the two pouring spouts to get to 5", but the bottom of the pan is slightly less than 3"... BIG DIFFERENCE... In my opinion, that is gross misrepresentation of the product because it IMPLIES that the cooking surface if 5" diameter when it absolutely IS NOT... EDIT: The 7" includes the HANDLE...Otherwise, the pan itself is nice looking, sturdy, quality material, and just like its big brothers.
Answer: The bottom of the inside is 3 1/4" in diameter while the top of the interior is 4 1/4".  Hope this helps.  MJ Moore, Detroit
