In the US we call large or wide patterns B52 patterns and as a controller I DO NOT like them and will tell you to tighten your pattern up closer to the airport, I do this for your safety and so that I can better control pattern traffic.
Wide patterns make it harder for the controller to see you, and to give you a sequence. In a situation with multiple acft in the pattern, you run the risk of being cut off by someone else who is flying a normal pattern.
If for some odd reason you want to fly wide patterns, ask for approval from ATC, this way you don't surprise the controller.
