That can only be achieved by buying the extentions. It's misleading and digitec/galaxus should add that in the description. I've measured the gate (white part) which comes to ~68.3 cm and then with those 4 clamp-thingies you can fit it to a ~80 cm door frame. For anything wider you need the extensions. Hope that helps. Oh, and I did find an image showing extentions and their ranges on amazon.de https://www.amazon.de/Safety-1st-24304310-Treppenschutzgitter-Verl%C3%A4ngerung/dp/B00EVR5KHG/ref=sr_1_2?adgrpid=1194070282761252&hvadid=74629510789996&hvbmt=bb&hvdev=c&hvlocphy=153702&hvnetw=s&hvqmt=b&hvtargid=kwd-74629598312545%3Aloc-175&hydadcr=15529_2314800&keywords=safety%2B1st%2Beasy%2Bclose%2Bdeco&qid=1669995914&sr=8-2&th=1
