This article discusses the relevance of determining wind loads on freely waving flags in connection with the emerging trend towards the competitive construction of ultra-high flagpoles equipped with flags of a huge area. The main scientific works have been reviewed in which attempts to investigate the complex phenomenon of flow around a waving flag was made. A comparison of wind loads on the flags calculated using different approaches from codes and standards as well as from available technical literature is provided. As a result of comparative analysis, significant differences in wind loads determined using various methods were revealed. Recommendations for engineers and designers are developed and provided in this paper.
