For maximum efficiency, never use a duct of a smaller size than the manufacturer’s specifications, because this will lead to a lack of suction performance and generate more noise.
The more powerful range hoods require greater duct sizes, up to 10” diameter. Refer to the range hood specifications or to its installation guide to make your choice.
