Question: What does the bowl measure across on the bottom?
Document: The bowl does not fit my mixer --  bottom is to small. Apparently the mixer I have is not a standard size as I can only find one size bowl to fit it. However the bowl is a quality purchase and I do use it -- just not with my mixer.
This bowl is perfect for smaller recipes. The only trouble I had is that after one hand-washing, the bottom of the inside of the bowl developed tarnish spots that smelled like rust. I returned it for a replacement (that came 2 days later! )and have not had that issue again.
I have never had problems with the ingredients flying across my kithcen, just keep the mixer at slow speed when mixing dry ingredients. In fact, this bowl is a great addition to your favorite mixer. Delivery by Amazon, was fantastic as always, and the price, the best!
this bowl is so convenient for me. i thank you for being such a good company to deal with and for your great prices.
The bowl was given as a gift. Arrived fast and there were no dings from it being tossed about during  shippment.
This bowl is perfect for my mixer. This is a good find because the price is reasonable. Live my bowl.
I'm only upgrading the review to 4 stars due to the defective first bowl.
We received the mixing bowl in a timely manner and in excellent condition and it works with our new mixer.
This bowl is exactly what I wanted, and does exactly what I need it to do. KitchenAid has once again exceeded my expectations.
But if you're short on space and would like a bowl for small jobs, this would be a good buy.
Answer: I had to measure from the underside and it is about 3 inches. Hope that helps
