Choosing between 60cm, 70cm, 80cm and 90cm induction cooktops in Australia — cutout dimensions, zone layouts, and matching pan sizes to zones.
60cm is the default width in Australian kitchens, dropping into a cutout commonly around 560 x 490mm and offering four zones — enough for the large majority of households. 90cm models add a fifth zone and more space between pans, but cost substantially more, often need a higher-rated circuit and a deeper benchtop, and consume 30cm of preparation space you no longer have.
The more useful question than width is zone layout. Two cooktops with the same four zones can be very different to cook on depending on zone diameters and the spacing between them — and the constraint people actually hit is not running out of zones but discovering that four full-size pans physically collide. Check the largest zone against your biggest frypan, the smallest against your milk pot (most cooktops will not detect a base under about 110–120mm at all), and the gap between zone centres against two pans you would genuinely use together.
