In the United States, the most typical wall height is 8 feet. The walls of some luxury residences are 9 or 10 feet high, whereas the walls of some older homes are only 7 feet high.
Most manufactured homes feature 8-foot ceilings, similar to regular homes, while many have the choice of 7-foot 6-inch or 9-foot ceilings. The most common wall height in houses in nations that use the metric system, such as the United Kingdom, is 2.4 metres (about 7 feet 10.5 inches), while newly built residences in these countries may have ceilings that are 2.55 metres, 2.7 metres, or even 3 metres high.
