It’s a common question, how big is SEMA, so just how big is the 2019 SEMA Show?

The SEMA Show is the aftermarket industry’s annual trade show in Las Vegas at the massive Las Vegas Convention Center and it’s hard to describe if you haven’t attended.

It’s a four-day aftermarket industry event that brings in 162,000 attendees including more than 70,000 buyers from the industry. Attendees come from all over the U.S. and 140 countries. They come to see more than 2,400 exhibiting companies.

One of the interesting statistics is the length of one of the exhibit halls, the Upper South Hall where you find truck products, business services, powersports companies and some first-time exhibitors. This is only one of several halls that contain the SEMA Show.

How big is SEMA?

The Upper South Hall is 464,658 square feet and is approximately 1,690 feet end-to-end. The Empire State Building is a “mere” 1,454 feet tall including the spire. If you could somehow lay the Empire State Building on its side with its base at the entrance to the Upper South Hall, the tip of the antenna would end near the Rhino Cart booth, #34309 or the Fumoto booth, #34308.

There are 1,500 feature vehicles scheduled and over 3,000 products featured in the New Products Showcase.
