A standard pack of cigarettes typically contains 20 cigarettes. This is the most common and regulated pack size in many countries, including the United States, where it is a legal minimum requirement

. However, pack sizes can vary depending on the country and brand:

• In the U.S., packs usually have 20 cigarettes, but some brands offer packs of 25

• In Australia, packs commonly contain 25 cigarettes, with some having 26, 30, or even 40 or 50 cigarettes

• Canada often has packs of 25 cigarettes but also sells packs of 20

• In the UK and many European countries, 20 is standard, but packs of 10 or other sizes may also be available

• Some Asian countries may have packs with 14 or 25 cigarettes

Additionally, cigarette cartons generally contain 10 packs, totaling 200 cigarettes

. In summary, while 20 cigarettes per pack is the global standard and legal norm in many places, variations exist based on local regulations and market preferences.
