Why is the kitchen generally hanging ceiling to 2 4 meters high, my kitchen is 2 9 meters high,

Of course not. The height of the lifting frame is different for each unit. Of course, the height of the ceiling hanging will be different.

This height of yours is good. When making cabinets, wall cabinets can be made a little higher. There will also be plenty of storage space.

Of course, it also depends on the actual size of the kitchen. If the area is too small, the wall cabinet will be made too high, which will give people a depressing feeling. If the kitchen area is large enough, the height of the wall cabinet should not exceed 960.

The area is small, the roof is too high, and the space feels bad.

It depends.

If the area is not too small, it is still a little higher.

This makes cooking cooler in the summer.

As long as you consider the space for ventilation equipment and drain pipes, you can make it as high as you want. But now the porcelain tiles on the market are generally 300, 450, 600 specifications, so you should also consider the beauty of the tile paving, do not have a very small piece of porcelain.

The kitchen ceiling can block the sewer pipe that can be seen, don't hang it too low, there will be a sense of depression.

Personally, decide how you want to decorate your own house.
