A big sized stall is always good to have because exhibition booth designers can show their creativity for an exhibition design but if you have a small booth size it is very difficult for a designer to give a creative design with in size limits. Not only that, there are some other constraints also like design guidelines given by the exhibition an organizer is one of that. The exhibition booth designers have to design the booth exhibition design according to that.
There has to be a balance of creativity, guidelines, attraction, theme, etc. and above all the budget of client with in which a designer has to work. The designers work on the design in form of a sketch first of all which is approved by the client and after that it is created in a 3D format with the help of latest software like 3D Max, Maya, etc. The design may undergo lot of iterations until it is approved by the client and at last it is submitted to the trade show organizers for final approval. Once it is approved the design is sent for final execution.
