What cutout and cooktop size does Bosch list?

Source: Bosch spec sheet (PDF), page 1. The page 2 drawing repeats the cutout as 34 15/16 (887) by 19 1/8 (486), inches with millimetres.

Does it fit a KitchenAid KCGS556ESS cutout?

Not exactly. Bosch's cutout width, 34 15/16 in, falls inside the KitchenAid KCGS556ESS range of 34 7/8 to 35 5/8 in, but Bosch's cutout depth, 19 1/8 in, is below the KitchenAid minimum of 19 1/2 in.

This comparison is our reading of the two makers' figures. KitchenAid figures: our KCGS556ESS page, from W11116971C.

Other 36-inch gas cooktop: Whirlpool WCGK5036PS. All cooktop cutouts.
