The common sizes of flagpoles in front of hotels, enterprises, factories, schools, squares, and office buildings are:
1. Generally, there are 3 or 5 enterprise flagpoles, with the Chinese national flag in the middle and the enterprise flag on both sides. The enterprise flag is generally half the height of the national flag flagpole, and the highest national flag in the middle cannot exceed 30 meters.

If it is a Sino foreign joint venture, the Chinese flag should be the same height as the foreign flag, but during actual construction, the Chinese flag pole can be slightly higher than the foreign flag pole, which is generally 50mm.
3. The government and military generally use a flagpole with a height of no more than 30 meters, typically ranging from 12 meters to 28.8 meters.
The general height of square flagpoles is 18 meters to 29.8 meters.
5. The height of the flagpole in the sports hall is generally 9-15 meters.
6. Hotel flagpoles should be both luxurious and dignified, with a height ranging from 12 meters to 19.8 meters. Generally, 5 flagpoles are used, with the Chinese national flag in the middle and the flags of other countries or the hotel's own flag on both sides.
7. The school flagpole generally adopts one flagpole, which raises the Chinese national flag and has a height between 12 meters and 15.8 meters.
8. Factory flagpoles generally use 3 flagpoles, but if it is a Sino foreign joint venture or foreign-funded factory, 5 or more flagpoles can also be used, with a height generally ranging from 8 meters to 15.8 meters. For multi story factories or office buildings, higher flagpoles can be selected.
The commonly used sizes of national flags and company flags include: second flag 160 * 240, third flag 128 * 190, and fourth flag 96 * 144; These three types of flags are commonly used on flagpoles in front of hotels, businesses, factories, schools, squares, and office buildings. Let's briefly explain the other uses of these three commonly used specifications of national flags and company flags:

Size of the second national flag: 160 * 240cm; Commonly used on image flagpoles at the entrance of large enterprises such as enterprises, hotels, schools, and factories, the second flag is suitable for image flagpoles above a height of 15 meters; It can also be used as a team flag for outdoor expansion, a cheering flag for sports events, etc. Due to the slightly larger size of the second flag, it is only occasionally used as a team flag for outdoor expansion. When used as a cheering flag, it is usually accompanied by a 3-meter-long metal flagpole, and cheerleaders can hold it with both hands and wave it vigorously for better results; When using it as an outdoor expansion flag, you can choose whether to equip it with a flagpole, mainly because the size of the second flag is too large for outdoor expansion flags, making it inconvenient to hold. It is usually only used for group photos and souvenirs, so the flagpole is only an optional option; A 5cm pole cover will also be made on the left side of the flag, and the other three edges will be pressed with a sewing machine to increase the service life of the flag.

Size of the third national flag: 128 * 192cm; The purpose of the second flag is basically the same, commonly used on image flagpoles at the entrance of large enterprises such as enterprises, hotels, schools, and factories. The difference is that the second flag is suitable for image flagpoles with a height of more than 15 meters, while the third flag is generally only used on flagpoles with a height of 10-13 meters. Some sports teams also use the third flag as the leader flag for sports events; The third flag can also be used as a background decoration flag for conference rooms, a team flag for outdoor expansion, and a cheering flag for sports events. Compared to the second flag, the third flag is more suitable for outdoor expansion flags and sports event cheering flags, and waving it with a flagpole is more effective; A 5cm pole cover will also be made on the left side of the flag, and the other three edges will be pressed with a sewing machine to reduce the damage caused by strong winds to the flag.

Size of the fourth national flag: 96 * 144; It is generally used on the image flagpole of large enterprises, factories, hotels, etc. that are 9-10 meters high, as well as on the standing flagpole of conference rooms and offices. It is also used as the team flag for leading team members when entering sports games. When the fourth flag is used as the team flag, it must be accompanied by a dedicated metal flagpole; The other uses of the Fourth Flag are basically the same as the Second Flag and the Third Flag. It is used as a background decoration for conference rooms, a team flag for outdoor expansion, and a cheerleading flag for sports events. Compared to the size ratio of the Second Flag and the Third Flag, the Fourth Flag is more standardized as an outdoor expansion flag and cheerleading flag. A 5cm pole is also made on the left side of the flag, and the other three edges are also pressed with a sewing machine to reduce the degree of damage caused by strong winds to the flag.
