How many cigarettes are typically found in a standard pack?

A standard pack of cigarettes typically contains 20 cigarettes. This standardization is common in many countries and is rooted in packaging regulations and historical norms within the tobacco industry. The choice of 20 strikes a balance for consumers in terms of convenience and price, making it a widely accepted quantity.

In contrast, packs containing 10 or 30 cigarettes are less common and may be found in some specific brands or markets, but they do not represent the standard. A pack of 40 cigarettes would not only be impractical for typical consumer use but also largely uncommon, making 20 the definitive norm for a standard pack.
