The size of the lobby water sign

The size range of lobby water mark is relatively wide, and the sizes of different types of lobby water marks are different. Take the horizontal lobby water sign as an example, its width is generally between 1.2m-3.5m, its height is about 1.4m, and the included angle between the inclined plane and the horizontal plane is about 30 degrees, so the front and back depth should not be too large, which is about 1.2m, otherwise reading will be affected.
