Market sizing (events)

Event market sizing works best bottom-up. Instead of starting from an industry's total value and assuming a slice, build the exhibitor universe by name: list the suppliers in the segment, from trade directories, competitor floorplans, association memberships, and databases, then estimate what share would take a stand and at what average size. A hundred named companies with realistic stand values is a forecast; "1% of a $40 billion industry" is a wish. Do the same for the audience — count the buying roles within travel range — and sanity-check both against comparable shows in adjacent sectors or the same sector abroad, which tell you what penetration and pricing the market has already proven it will bear. Commercially, sizing drives the go/no-go on launches, the price paid in acquisitions, and honest growth targets for existing shows. The common mistake is top-down sizing with optimistic percentages, which produces big numbers and no accountability; nobody ever revisits whether the 1% appeared. One honest nuance: audience size and revenue size are different questions. Some large audiences support no exhibition because the supplier side is concentrated in five companies who don't need stands to reach anyone — size the paying side first.
