Market Sizing is a common business research method used to figure out how big a market is in terms of money or number of customers. It's like estimating how many pizzas are sold in a city or how much people spend on smartphones each year. Market research professionals use this skill to help companies understand business opportunities and make smart decisions about entering new markets. You might also see this called "market size analysis," "market estimation," or "TAM analysis" (Total Addressable Market). It's a key skill especially valued in consulting firms, market research companies, and business strategy roles.
