The above link may give you some idea regarding choosing right trade show display.
Choosing the right trade show display is very in trade shows. Because it is not necessary that all displays should suit all dimension booth. In case of larger booths you can select truss displays, modular displays
In case of small trade shows, you can opt to Table top displays, pop up displays
If your budget is high then you can also go with graphic displays. Make use trade show accessories, advanced technologies like LCD monitors along with your trade show displays to attract more customers.
Large expensive display booths are generally located near the show hall entrance. They typically fan out and give way to smaller booth spaces toward the back and perimeter.
You many want to keep some distance between you and your closest competitors.
Consider the architecture of the facility. Be aware of columns and variations in ceiling height.
Look for opportunities to stand out. Often, there are great opportunities away from the entrance or in another hall that can give you an advantage. Consider exhibiting near the restaurant entrance or in a space flanked by primary traffic aisles.
There are restrictions on height. Some shows strictly enforce these regulations. Don't assume the regulations in the United States are the same in Europe, Asia, and Latin America. They're not.
Don't discount perimeter booth spaces. Perimeter spaces often allow full height exhibits (up to 16 ft.). This advantage, along with placement at the start or end of high traffic aisles, can attract lots of attendees.
Consider splitting an island booth space with another company. Many shows allow two exhibitors to share a booth space and divide it to suit.
Start by knowing what size floor space you can afford at a trade show and then search for displays of that size until you see something that you like. This website ( http://www.cdsdisplays.com ) lets you search through trade show display ideas by size.
Go for lightweight and portable. Fabric displays offer the most lightweight options while giving you big, affordable full-color graphics. Message is everything so definately go for something that lets your display be a big billboard and then craft a strong message and bright visuals to grab attention.
Be approachable. Refrain from eating in the tradeshow booth, checking your Blackberry, or holding extended conversations with coworkers. It is human nature not to be rude and interrupt people and it will make your tradeshow exhibit seem uninviting.
Be sure to have a disengagement line or two. The best one is "thanks for stopping by", but if you are talking to an important prospect it might be better to say "where do we go from here?" or "how would you like me to follow up?"
Take notes. There are so many people and so little time. Brief notes will help you to be more effective with your follow-up.
Familiarize yourself with the entire convention agenda. Be aware of keynote speakers, educational sessions and social events. Prioritize them and make sure to attend. Be prepared to discuss these sessions with prospects who come to the booth.
Study the design of your exhibit. Read and understand the graphics. Have a plan for giving the prospects a quick tour of the booth and recording lead information for follow-up.
Develop a plan to deal with current customers efficiently so that they do not monopolize precious prospecting time.
Memorize a few greetings. Try not to ask questions that can be answered with a simple yes or no. Your goal should be to encourage the prospect to talk about themselves or their company, so that you can tailor your presentation to their interests.
