What materials and furniture need to determine the size! Ceiling fan light size is as follows:
36 inches (wooden blade) installed diameter is 96CM6–10 square feet
38 inches (iron blade) installed after the diameter is 100CM8–12 square meters
42 inches (wood leaf) installed diameter is 108CM9–15 square feet
48 inches (iron leaf) installed diameter is 126CM12–20 square feet
52 inches (wood leaf) installed diameter is 132CM13–25 square feet
The larger the size, the wider the range of blowing wind, but the load of the motor will be heavy, so the rotation speed will be slow; wind power will also be reduced. On the contrary, the smaller the size of the fan blade, the smaller the range of blowing air, but the motor load will be light, so the rotating speed will be fast and the wind power is naturally high. Rooms with poor natural air flow or very hot weather areas should be properly sized to achieve the right amount of airflow.
