Recreational basketball rules — game clock, team size, fouls and bonus, scoring, and overtime for adult rec leagues, adapted from NFHS/FIBA.
Players
5v5 (rec: also 3v3)
Game length
2 × 20 min running clock (typ.)
Court
94 × 50 ft (rec: 84 ft common)
Scoring
2 / 3 pointers, 1 pt FT
Common: min 2 women on court; some use 2-pt women’s arc bonus
Co-ed divisions typically require at least two women on court at all times; some leagues score women’s three-pointers as four or add similar bonuses — check the league rule set.
5 on court; min 4 to start
Five players per side on court. Leagues commonly allow starting with four to avoid forfeits; rosters usually carry 8–12.
2 × 20 min running; stop clock last 2 min
Most rec leagues play two 20-minute halves with a running clock, switching to a stopped clock in the final two minutes of the second half if the margin is within a league-set threshold (commonly ≤10).
3 min stop-clock; regular season may end tied
Playoff overtime is commonly 3 minutes with a stopped clock in the final minute. Many leagues let regular-season games end tied after one OT.
2 per half (typ.), 1 in overtime
Rec leagues typically allow two timeouts per half (no carryover) and one per overtime period; the clock stops during timeouts even when otherwise running.
Bonus at 7 team fouls; double bonus at 10
On the 7th team foul of a half the opponent shoots one-and-one; on the 10th, two shots. Shooting fouls are always two (or three) free throws.
NFHS Rule 4-8
None in most rec leagues
Most rec leagues play without a shot clock; referees may apply a five-second closely-guarded count and stall warnings late in games.
2 inside the arc, 3 beyond, 1 per free throw
Field goals count 2 points, or 3 from beyond the three-point arc. Free throws count 1.
NFHS Rule 5
Legal in play; no hanging on the rim
Dunking is legal during live play. Hanging on the rim (except to protect a player underneath) is a technical foul, and pregame dunking is commonly barred by facility rules.
5 personal fouls
A player is disqualified on their fifth personal foul. Two technical fouls also disqualify and typically carry a league suspension review.
These are the recreational baselines. Leagues on UnderDraft publish their own rule sets — players see exactly which variations apply before every game, and referees enforce them from the sideline.
