In some cities, it is about 2.8 or 2.9 meters, but the thickness of a board should be deducted, so the clear height of the living room and room is generally around 2.8-2.9. Sometimes the living room is thicker than the room, so the clear height of the living room is smaller than that of the room. However, if the bathroom is equipped with a concave pool, the height of the bathroom is generally only about 2.5 meters. After the renovation, cement sand and floor tiles (or floors) should be laid on the ground, so the ceiling should be made on it, and the clear height of the living room is only about 2.6-2.7 meters.
Theoretically, indoor walls are generally 120,180,240, and there is a single brick wall, that is, there is only one stacked bottom, in that case, it is 60mm wide. 370 wall is rare indoors, basically exists in the form of columns, and may also be used in large exhibition halls and offices. The algorithm is click calculation: 24 walls: masonry 240mm(24cm), along two 2× 1 15+ 10 (mortar joint) =240mm(24cm). 37 wall: after one piece is fixed, it will be 240+115+15 (two mortar joints) = 370mm；; Follow three 3× 1 15+25 (three mortar joints) =370mm(37cm). This is a layer-by-layer assembly, and the vertical joints between layers should be staggered by not less than 60mm, otherwise it is called "common fault". The masonry (broken flowers) of the wall (meeting) is commonly used, such as Yishun Dingyi, Sanshun Dingyi and Meihua Shunding.
