How the NFL Season Is Structured: Preseason, Regular Season and Playoffs

By 4Football Staff · September 21, 2026 · 11 min read

A plain walk through the three phases of an NFL year, from exhibition games and roster cuts to the 17-game schedule, the bye week, the playoff rounds and the Super Bowl.

You turn on the television one August evening and see a team's starters leave the field after a single series. A month later the same team is playing games that count. A few months after that, fewer than half of the league's teams are still playing in January while the rest are already thinking about the draft. Nothing about that rhythm is obvious if nobody has laid it out for you.

The National Football League (NFL) calendar has three competitive phases: the preseason, the regular season and the postseason. Each one has a different purpose, different rosters and a different set of rules about who plays and why. Understanding the purpose of each phase explains many things that otherwise look strange, such as why a coach rests his best players in a game that is televised nationally, or why a team with a worse record can still host a playoff game.

This article walks through the whole competitive year in order. The exact number of games, weeks and playoff teams has changed over the decades and can change again, so the numbers below describe the format in use in recent seasons. For today's matchups and results, use the schedule and scores pages, which always reflect the current season.

The year is longer than the season

Before the phases, a quick distinction that clears up a lot of confusion. The NFL runs on a league year, which begins in March when contracts can be signed and traded and the new fiscal and roster rules take effect. The season is the stretch from the first preseason game to the Super Bowl. Everything else (free agency, the draft, minicamps, training camp) happens between seasons but inside a league year.

That matters because the league year, not the season, is what the salary cap and most roster rules are measured against. A player signed in April is working under the new league year even though no game has been played. If you want the full off-field calendar, see the NFL offseason calendar, month by month. Here we stay on the competitive part.

The preseason: practice with a scoreboard

The preseason is a short run of exhibition games played in August, after training camps open. In recent years each team has played three of them; for decades before the league moved to a 17-game regular season each team played four. The results do not count in the standings, and no one gets a playoff spot or a draft position out of them.

What the games are for

The preseason exists for evaluation. A team arrives at camp with a roster that can be as large as 90 players, and by the end of the preseason it has to cut that number to the regular-season limit. The exhibition games are the last live tryout. Coaches want to see:

• Rookies and undrafted free agents playing against players from another team's uniform, which is different from practicing against their own teammates.
• Players competing for the last roster spots, especially at depth positions and on special teams.
• Young quarterbacks running a full offense under a game-day clock and noise.
• New schemes, new offensive line combinations and new defensive alignments in a setting where a mistake costs nothing.

Who plays and who does not

Established starters often play very little or not at all. Each coach decides for himself how much risk to take with proven players, and the common reasoning is simple: the information gained by playing a veteran quarterback for a dozen snaps in August is small, and the injury risk is the same as in any other game. Backups and players fighting for roster spots usually play most of the snaps, which is why preseason box scores are full of names that never appear again.

The game that opens the preseason is traditionally the Hall of Fame Game, played in Canton, Ohio, the home of the Pro Football Hall of Fame. It is tied to the induction weekend for the new class.

Roster limits and cut-down day

Roster size shrinks in steps defined by the league. The offseason roster can be as large as 90. Before the regular season begins, every team has to reach the active roster limit, which has been 53 players in recent years. The deadline for that is known as cut-down day, and it is followed immediately by a wave of waiver claims and practice squad signings. Details on how that works are in Waivers, Claims and Cut-Down Day. The interim steps in the cut process have been changed over the years, so check the league's current operations rules if you need the exact schedule.

The regular season: 17 games in 18 weeks

The regular season is the part that determines the playoff field. In recent seasons each team plays 17 games over 18 weeks, which means every team gets exactly one bye week, a week with no game. From 1978 through the 2020 season it was 16 games over 17 weeks, and before 1978 it was shorter than that.

How the calendar fills in

The season traditionally opens on a Thursday night in early September, with the reigning champion hosting. Most games are played on Sunday afternoons, in two main windows, with a Sunday night game as the headline of the day. Monday night has a long history as a showcase slot. Thursday night games are played during most weeks of the season. Late in the season the league also adds Saturday games once college football winds down, and holidays such as Thanksgiving and, in recent years, Christmas have featured games. Which games land where is the product of the schedule formula and the television contracts, covered in The NFL Schedule Formula and How NFL Games Reach Your Screen.

The bye week is placed somewhere in the middle of the season, never in the first few weeks and never in the final stretch. For a player it is a chance to recover; for a coach it is a chance to look at film of the first half of the season and fix what is not working. Fantasy managers and bettors also pay attention to it, because an off week changes how a team looks the following Sunday.

Where the 17 games come from

Each team plays six games against its three division rivals (home and away), then a rotating set of opponents from other divisions and, finally, one more game against a team that finished in the same place the year before. The formula guarantees that over several years every team plays every other team, and that every team hosts and visits a fair mix of opponents. The details, with a worked example, are in the schedule article. For now, the key point is that the 17 games are not equally difficult across teams, and that is by design: the league deliberately ties part of the schedule to the previous year's standings so that strong teams meet each other more often than the weakest ones do.

The standings and the tiebreakers

At the end of 18 weeks the teams in each of the league's eight divisions are ranked by record. The league has two conferences, the American Football Conference (AFC) and the National Football Conference (NFC), with four divisions in each. Every division winner makes the playoffs, and so do the next three best records in the conference, called wild cards. When two teams finish with the same record the league applies the tiebreaker list explained in How NFL Playoff Tiebreakers Actually Work. A tie game is possible and counts as half a win and half a loss in winning percentage; see How Ties Count in the NFL Standings.

You can watch this sort out live on the standings page. Keep in mind that our page is a simplified version of the full league list and may differ from the official seeding late in the year.

Overtime

If a regular-season game is tied after four quarters, the teams play a single overtime period of 10 minutes in recent seasons (earlier it was 15). The game can end in a tie if neither team wins in that time. The playoffs are different: a playoff game has to produce a winner, so overtime periods are played until someone wins. NFL Overtime Rules Explained covers the possession rules, which have been modified several times.

The postseason: single elimination

The playoffs take the 14 qualifying teams, seven from each conference, and reduce them to one champion through four rounds of single-elimination football. A loss ends a team's season; there are no series. That is the biggest structural difference between football and most other American sports, and it is why a playoff run feels so fragile even for the best team.

The four rounds

The No. 1 seed receives a bye in the first round, so it plays one fewer game and has an extra week of rest. In the divisional round the bracket is re-seeded rather than fixed: after the first round, the best remaining seed plays the worst remaining seed. This is one reason the top seed is so valuable, and it is why teams fight for it even when they have already clinched a playoff spot. A longer treatment is in How the NFL Playoff Bracket and Seeding Work.

Home field in the playoffs

Through the Conference Championship round, the home team is the higher seed, with one common surprise: a division winner is always seeded above a wild card, even if the wild card has a better record. A 9-8 division champion can therefore host a team that won more games. The rule exists to give the division title real meaning, but it produces some awkward looking games every few years.

The Super Bowl

The league championship game is played at a neutral site, which is chosen by a vote of team owners years ahead of time, and it has been held about two weeks after the conference title games. The designated home team alternates between the AFC and the NFC from year to year, and that designation decides who wears which uniform and which sideline each team uses; it does not decide the stadium. The winner receives the Vince Lombardi Trophy. The Super Bowl: How the Game Is Organized goes into the host-city process.

What changed over time

The structure above is a snapshot, and every piece of it has moved at some point:

• Regular-season length: from 14 games, to 16 games from 1978, to 17 games in recent years.
• Preseason length: reduced from four games to three when the 17th regular-season game was added.
• Playoff field: the number of teams has grown in steps over the years. In recent years it has been seven per conference, and before that six.
• Overtime: moved from sudden death toward rules that guarantee more possessions, and shortened from 15 to 10 minutes in the regular season.
• Neutral-site and international games: the league now plays some regular-season games outside the United States, which affects the home and away balance of the schedule. See International Games: How the NFL Plays Abroad.

When you read an old article or watch a classic game, remember that the numbers you are hearing about (games per season, teams in the playoffs) may be different from the numbers today. When you read a new rule announcement, remember that the league's owners can and do change these details. For anything with a deadline attached, check the league's current announcement rather than relying on memory.

Common misunderstandings

"The preseason record means something." It does not count toward anything. Some teams treat the games almost as practices, and a team that goes undefeated in August has no more claim on January than one that lost every exhibition.

"A bye week is a vacation." Players get time away from the facility, but coaches use the week for self-scouting, and the week sits in the middle of the season at a point the league chooses, not the team.

"The best record gets the best seed." Mostly, but the divisions come first. A division winner outranks every wild card, so the second-best record in the conference can end up as a No. 5 seed if it did not win its division.

"The top seed has already won a round." It has not. Of the seven playoff teams per conference, six play in the Wild Card round and the seventh, the No. 1 seed, simply enters the divisional round without playing a first game, which is why the bye is valuable but not a victory.

"A tie means both teams go to overtime again." Only in the playoffs, where the game must have a winner. In the regular season a tied game can end the day as a tie.

A season at a glance

Think of the year as three filters. The preseason decides who is on the roster. The regular season decides who is in the field and in what order. The postseason decides the champion. Each filter applies a different pressure: the first rewards depth and effort, the second rewards consistency over four months, and the third rewards being ready on one particular Sunday.

If you follow a single team, the useful dates to circle are the opening game, the bye week, the final month when the standings tighten and the Wild Card weekend. For the league as a whole, the dates that matter are the cut-down deadline, the trade deadline in the middle of the season, the end of the regular season and the Super Bowl. You can follow each of those from the teams pages and the live standings.

The short version

• The NFL year has three competitive phases: preseason exhibition games, a regular season, and single-elimination playoffs.
• The preseason does not count toward the standings. Its job is evaluation, and it ends with the cut from a large camp roster to the active roster limit.
• In recent seasons the regular season is 17 games in 18 weeks, with one bye week per team.
• Seven teams per conference make the playoffs: four division winners and three wild cards. Only the top seed skips the first round.
• Division winners are always seeded above wild cards, which is why a team with fewer wins can host a playoff game.
• After the first round the bracket is re-seeded, so the highest remaining seed always meets the lowest remaining seed.
• The Super Bowl is played at a neutral site, and the format details (number of games, playoff teams, overtime) have changed over the decades and may change again.
