Section 1: Introduction
NCAA Women's Basketball is the collegiate variant of women's basketball played under the rules of the National Collegiate Athletic Association. NCAA women's basketball differs from NCAA men's basketball in several key ways: four 10-minute quarters (vs. two 20-minute halves in M's, since 2015-16), per-quarter team-foul bonus reset, and a smaller official ball (size 6). Other rules — 30-second shot clock, three-point arc distance, court dimensions — match the men's collegiate framework.
The canonical text is the NCAA Women's Basketball Rules Book, published on a two-year cycle by the NCAA Women's Basketball Rules Committee. The current edition is the 2025-26 NCAA Women's Basketball Rules Book, in effect through the 2026 NCAA Division I Women's Basketball Tournament and the 2026-27 regular season.
For the men's collegiate variant see Basketball (NCAA Men); for international rules see FIBA Official Rules; for the WNBA professional game see WNBA Official Rulebook; for 3x3 see FIBA 3x3 Rules. This entry summarizes the major rule mechanics for educational purposes; it does not reproduce rule text.
Section 2: Equipment
The Ball
- Women's ball: size 6, circumference 28.5 inches (72.4 cm), weight 20 oz (567 g)
- NCAA-approved leather or composite cover; orange standard color
Court Equipment
- Basket: 18-inch ring at 10 feet (3.05 m) height
- Backboard: 6 feet wide × 3.5 feet high, rectangular
- Net: white cord, 15-18 inches
- Shot-clock displays at each end (30-second)
- Game clock visible to players, officials, and spectators
Player Apparel
Same uniform standards as the men's variant: team uniform with school logo and unique numbers, athletic shoes for indoor surface. Mouthguards recommended; jewelry prohibited except per religious-exemption framework.
Section 3: Playing Area
- Court dimensions identical to NCAA men's: 94 feet × 50 feet (28.65 m × 15.24 m)
- Lane: 12 feet wide × 19 feet from baseline to free-throw line
- Three-point arc: 22 feet 1.75 inches (NCAA W's expanded to match the men's distance for the 2021-22 season)
- Restricted-area arc: 4-foot radius for charge/block decisions
- Center circle: 12-foot diameter
- Free-throw line: 15 feet from the backboard
Bench, scorer's table, and 28-foot coach's box layout match the men's specification.
Section 4: Players & Officials
- 5 players on court per team; rosters typically 13-15 for D1
- Three-person on-court crew (referee + two umpires); scorer, timekeeper, shot-clock operator
- Video-replay official for designated reviewable situations
- Coaches' challenge framework: each team has one challenge per game (out-of-bounds in last 2 minutes, basket interference, goaltending, made-basket validity, flagrant fouls)
- Media timeouts: 4 per quarter at predetermined intervals; do not count against team timeouts
Substitutions
Unlimited substitutions at dead-ball stoppages on the scorer's signal; substituted players may re-enter.
Section 5: Rules of Play
Game Structure
- Four 10-minute quarters (adopted 2015-16; distinguishes NCAA W's from NCAA M's halves)
- 2-minute breaks between Q1/Q2 and Q3/Q4; 15-minute halftime
- 5-minute overtime periods until a winner is determined
Team-Foul Bonus (Per-Quarter Reset)
- Bonus starts at the team's 5th team foul per quarter — the offended team shoots 2 free throws
- Team-foul totals reset to zero at the start of each quarter
- The last 2 minutes of any quarter: any team foul carries 2 free throws regardless of count
- This per-quarter framework differs from NCAA M's per-half 1-and-1 (7th) + double-bonus (10th) structure
Shot Clock
- 30-second shot clock — resets to 30 on possession change; resets to 20 on offensive rebound
- Shot must contact the rim before the clock expires; failure is a violation
Other Mechanics (Match NCAA M's)
- Closely-guarded 5-second rule (defender within 6 feet)
- Backcourt 10-second rule
- 3-second lane violation
- Alternating-possession arrow for jump-ball situations after the opening tip
Section 6: Scoring
- 2-point field goal inside the arc; 3-point field goal beyond the 22'1.75" arc; 1-point free throw
- Most points wins; tied at end of regulation = 5-min OT periods until winner
Section 7: Violations & Penalties
Personal Fouls
5 personal fouls = foul out. Common personal fouls: blocking, charging, pushing, holding, hand-checking, illegal screen. Shooting fouls award 2 or 3 free throws depending on shot location, with and-one if the basket counts.
Technical Fouls
- Class A unsporting (taunting, fighting, profanity): 2 FT + possession; 2 = ejection
- Class B (delay-of-game, illegal substitution): 1 FT + possession
- Class C (administrative): 1 or 2 FT
Flagrant Fouls
- Flagrant 1: excessive contact not directed at head/neck — 2 FT + possession; remains in game
- Flagrant 2: dangerous or intentional contact, head/neck contact — 2 FT + possession + ejection
- Replay review confirms flagrant fouls
Other Violations
- Traveling, double dribble, carrying, goaltending, basket interference
- 5-second closely-guarded, 10-second backcourt, 3-second lane
Section 8: Safety Considerations
Concussion protocol identical to NCAA men's: medical observers and team medical staff have authority to remove a player; graduated return-to-play assessment required. Flagrant-2 ejection framework protects against head/neck contact. Backboard and goal padded to NCAA-approved spec; certified athletic trainer required at every NCAA-sanctioned game; emergency action plan with AED access at every venue.
