Height of cooktop/oven + length of countertops

2) If I have calculated this correctly without coffee, the cut would be too close to the hotplate. On the one hand, there is possibly a risk of breaking due to the thin bridge, but above all, the joint/cut edge being so close to stoves/sinks is not good because of liquid.

1) With the backhoe, only the front is 594mm high, the rest of the housing above which the cooktop lies is "only" 579mm or 572mm. Should then fit,

Regarding 1): As Schmidti82 already wrote, the front is higher than the built-in part of the oven. Many manufacturers assume that the cooktop is installed above an oven from the same manufacturer and do not specify minimum distances. For ventilation, you should definitely make a cutout in the back panel of the cabinet with the prescribed dimensions.

Regarding 2): Ikea specifies a minimum distance of 10 cm between the cooktop and the edge of the countertop for Karlby (you can view the instructions online).

KARLBY is just particleboard with a 3.5 mm thin veneer. The surface is not resistant and needs to be maintained. A Personlig laminate worktop is cheaper, more durable, and easier to care for. Consider whether a continuous laminate worktop, which you can later replace with a solid wood top, is currently the better choice.

Thank you very much for the answers.

IKEA expert, we were already considering whether a wooden surface – regardless of whether veneer or solid – is really right for us. Now I am really not sure. But assuming we initially use two removable laminate panels and perhaps later replace them with a Personlig panel. As far as I can see, among the removable ones only the SÄLJAN has a thickness of 3.8 cm, which would be necessary for the installation of the oven and the cooktop. Unfortunately, it is not available in the desired look, but we could probably live with black for now. The question remains whether it will fit at all. Even taking into account Schmidti’s helpful tip (thanks!), I have the 579mm oven + 55mm cooktop - 38mm worktop = 596mm, which should fit but leaves only 4mm for the ventilation gap. Unfortunately, as mentioned, the installation instructions do not specify exactly how large the ventilation gap between the cooktop and oven must be. Does anyone perhaps have experience and can say whether this is usually sufficient?

The alternative would of course be to choose other appliances, but I would prefer to avoid that if possible – I have already carefully selected them (but apparently not quite carefully enough regarding the size)!

Why not just a PERSONLIG?
