Workflow · Size a Market
Illustrative walkthrough
Fix what is in and out of the market, so the size answers a specific question rather than a category.
Size from demand build-up — units, price, attach — rather than a top-down TAM headline.
Split the market into the segments that behave differently, so the mix is visible.
Attribute growth to its drivers and project a range, not a single line.
Grade the estimate's confidence and name the assumptions that most move it.
Evidence gap
A live run names the specific evidence to firm up before deciding here; this worked example marks where that check lands.
Final output
Size a Market answers “How large is this market, how fast is it growing, and which segments matter?” This worked example walks the full methodology step by step; a live run applies it to your chosen scope, carrying its own evidence, scores and recommendation.
