From the Bosch OM ”In order to achieve a good cooking result, ensure that the ferromagnetic area of the cookware base corresponds to the size of the cooking zone.”

A good cooking result to me means optimal performance. If I don't match the sizes of the burner and the pot am I getting suboptimal performance or am I actually damaging the cooktop?

I’ve never closely measured anything. I just pick the hob that looks close to the size of the pan. Never had a problem with cooking results or the induction top in seven years.

Ditto, I’ve had Bosch induction cooktops in two houses now - just pick what looks like approximately the right size and have at it. I’ve certainly never measured.

Problem solved then! Now all that's left to do is buy compatible cookware! Looking into cast iron to avoid humming and other noises which is my biggest fear (aside from kitchen lights flickering while stove is on and everything else I've read on the forum over the past 5 hours)

I just bought a house and replaced the radiant cooktop with a 30 inch Bosch Benchmark induction cooktop. At my other house I have an Electrolux induction range - their least expensive one eight years ago. I have a variety of cookware there - All Clad, Le Creuset and I bought an inexpensive set of Duxtop on A'zon to replace some RevereWare pieces I used from time to time. That cooktop does some clicking on lower settings - like heat on, heat off. I don't recall much of the buzzing that people mention but maybe there's some of that. At the new house I have a couple pieces of Le Creuset and a Lodge cast iron frying pan but everything else is a new set of Duxtop. I haven't used the new cooktop all that much - just had it in place for about a week - but I don't notice any kind of noise whatsoever. I don't know if the difference is the cooktop or the pans. The first Duxtop pans I got recommended not putting in the dishwasher. The new ones are dishwasher safe so maybe they're different. In any case whatever noise I've had has never bothered me and I would certainly NOT let it prevent me from using induction.

Thanks for the recommendation wdccruise! I always wanted to try IKEA cookware and all I needed was a recommendation (just placed an order for a 5 qt pot). I really want to try All Clad but man it's expensive! Le Creuset is outside my budget but I want to try a dutch oven and will look at more affordable alternatives. In short, super excited to experiment!

Madein dutch oven is superior to the Le Creuset (I have both) also made in France and the price point is much better! https://madeincookware.com/collections/enameled-cast-iron

I actually pulled the trigger and bough a bunch of Le Creuset cookware and I opted for them because their dutch ovens are lighter compared to other brands. I have couple pieces and they all work great on induction. Another reason I prefer Le Creuset it because of their handles - I find them more comfortable compared to other brands. Made-In is great, too, if I didn't buy Le Creuset I'd definitely go with them!
