The height of a tiki bar roof is a personal choice that might vary depending on the design and style you wish to create. A usual advice, however, is to have a minimum clearance height of roughly 8 feet (2.4 metres) to allow for comfortable movement and to avoid a crowded sensation. This height provides enough headroom for most people and enables for the installation of thatched roofs or other ornamental components while keeping the tiki bar roof open and expansive.
