The 17 Laws of the Game Explained in Plain English

The laws of the game explained properly start with a single fact: seventeen laws govern every organised football match on the planet, from a county league fixture to a World Cup final. They sit in a document of roughly a hundred pages, maintained by one body rather than a parliament of leagues. That is why a supporter in Buenos Aires and a referee in Bolton still argue about the same clause, and why this lawbook can be read by anyone willing to take it one law at a time.

The laws were first codified by the Football Association in 1863 and have been maintained by IFAB since 1886. They are numbered, and the numbering is the most useful thing about them: when a pundit says "that is Law 12", they are pointing at a specific clause with a specific sanction attached.

Laws of the game summary: how the lawbook is arranged

The first four laws describe the stage and the equipment. Laws five and six cover the officials, which is where the modern game has grown fastest. Laws seven to ten deal with time, restarts and the result itself. Then comes the part everyone argues about: offside, fouls and misconduct. The last four laws cover the restarts that follow a decision.

1. Law 1 — The Field of Play. Dimensions, markings, the goal, and what happens if a goalpost is the wrong shape.
2. Law 2 — The Ball. Size, pressure and what to do when a ball bursts during play.
3. Law 3 — The Players. Eleven a side, substitutes, and the consequences of a player leaving the field without permission.
4. Law 4 — The Players' Equipment. Shirts, shin guards, jewellery and the referee's power to send a player off to fix a problem.
5. Law 5 — The Referee. Authority, discretion and the fact that a decision can still be corrected.
6. Law 6 — The Other Match Officials. Assistants, fourth officials and the video assistant referee.
7. Law 7 — The Duration of the Match. Two halves, half-time, and the added time that everyone now watches on a big screen.
8. Law 8 — The Start and Restart of Play. Kick-off, dropped ball and the coin toss.
9. Law 9 — The Ball In and Out of Play. When the game is live, and why the ball on the line is still in.
10. Law 10 — Determining the Outcome of a Match. Extra time, penalties and the order of kicks.
11. Law 11 — Offside. Position, phases and the moment the ball is played.
12. Law 12 — Fouls and Misconduct. Careless, reckless and excessive, plus every card in the book.
13. Law 13 — Free Kicks. Direct and indirect, and the four metres of respect.
14. Law 14 — The Penalty Kick. The spot, the keeper's line and encroachment.
15. Law 15 — The Throw-in. Two hands, both feet, and the foul throw nobody can quite define.
16. Law 16 — The Goal Kick. When the ball is in play, and how far a defender may stand away.
17. Law 17 — The Corner Kick. The arc, the ball in play, and a new route to a corner in the goalkeeper law.

The 17 laws of football: the clauses that decide most arguments

Four laws generate almost all of the noise. Law 11 decides whether a goal stands. Law 12 decides whether a challenge was a foul, a booking or a sending-off. Law 14 turns a single moment into a penalty. Law 5 is the one that explains why the referee on the pitch still has the last word, even after a video review.

The two clauses that decide most matches

If you only ever learn two sentences of the lawbook, make them these: the whole of the ball must cross the whole of the line for a goal, and a player is only offside when they become involved in active play. Between them, those two definitions account for more overturned decisions and more furious arguments than any other clauses in the document.

The rest of the lawbook is largely administrative, and that is not a criticism. Laws about the ball, the field and the equipment exist so that nobody has to negotiate them on the day.

How a law gets changed

Amendments are proposed by national associations, confederations or IFAB's technical panels, then tested in competitions before adoption. A trial can run for years before it becomes law, which is why ideas such as a stop-clock or a challenge system appear in some leagues and not others. When a change is agreed, it normally takes effect on 1 July, and competitions are given room to adopt it at the start of their own season.

Two articles are worth reading next to see the lawbook in action: Law 12 and the three words that decide every card, and the offside law explained phase by phase. For the changes still bedding into the current edition, our guide to the 2026-27 laws collects them in one place.

Five things the lawbook does not say

Most matchday arguments come from a clause that people believe exists and does not. Correcting those five beliefs in your own head solves more confusion than reading the whole document.

• “It was on the line.” The whole of the ball must cross the whole of the line. A ball touching the line is still in play.
• “He was offside when the ball was played.” Being in an offside position is not an offence. The offence is what the player does next.
• “There was no intent.” The handball law is built around arm position and movement, not on whether a player wanted the ball to hit them.
• “Last man, so it is a red.” Denying an obvious goalscoring opportunity has its own criteria, and the location of other defenders decides them.
• “Any contact in the box is a penalty.” Contact in football is normal. A foul requires carelessness or worse.

Each of those beliefs survives because it is nearly right most of the time. That is exactly why they are worth pinning down: the exceptions are the moments that decide matches, and the exceptions are all written into the clauses.

Read the seventeen laws once and football stops being a set of opinions. Every decision on the pitch traces back to a numbered clause, and knowing the number is half of understanding the argument.
