Generally speaking, the exhibition hall space is a four-dimensional art with perfect combination of time and three-dimensional geometric space. In this space, there are many spaces with different functions and sizes, which are organized in an orderly way and connected in series in an open and circular way. Through people's display behavior, the four-dimensional effect of combining time and space is displayed. The biggest feature of exhibition hall design space is that it belongs to the type of flowing space. The exhibition hall space is a single and multi-directional pure space, and its structure is dynamic and open, which can be combined into different space forms according to needs.

Generally speaking, the design space of the exhibition hall consists of the space around the exhibition area, including the upper space, exhibition space, sales space and exchange exhibition space, such as the exhibition hall of museums, large art galleries and large expositions. And it will extend a lot of auxiliary space, such as aisle space, lobby space, rest space and various service facilities space. In other words, to design the layout of the exhibition hall design space, we must first meet the needs of various functions in the exhibition hall design space, including the layout of the external space of the exhibition hall design area. Therefore, the design of exhibition hall space is usually carried out by grasping the theme of "moving |", using the rhythm of space and multiple routes to let visitors feel the change of time and space and the artistic charm of three-dimensional space in the flow.

An exhibition hall without reasonable planning and layout is not a good exhibition hall. The planning and layout of the exhibition hall and the allocation of space design directly affect the impression and experience of exhibitors. Therefore, if modern exhibition hall designers want to make the exhibition hall beautiful and attractive, they must make more efforts in the planning and layout of the exhibition hall design space, which can not only improve the aesthetics of the exhibition hall, but also make visitors feel good and deeply understand the true meaning and feelings of the exhibition hall designers in the design concept.
