Youth Basketball Game Format by Age: 3v3, 4v4 or 5v5?

Canada Basketball does not recommend the same number of players on the court for every youth age group.

The Youth Rules Guidelines use a progression from small-sided 3v3 and 4v4 basketball toward more traditional 5v5 basketball as players develop.

At U7–U8, Canada Basketball recommends 3v3 or 4v4.

At U9–U10, both recreational and competitive environments can use 4v4 or 5v5.

At U11–U12, recreational basketball can still use 4v4 or 5v5, while competitive basketball moves to 5v5.

At U13–U14, recreational basketball can use 4v4 or 5v5, while competitive basketball uses 5v5.

• half-court or cross-court play
• no formal scorekeeping or standings
• equal playing time
• a Game Leader
• no formal games in the program-design table, with modified small-sided games instead

What Game Format Is Used at U9–U10 Recreational?

Canada Basketball recommends:

4v4 or 5v5

for recreational U9–U10 basketball.

The court format is cross-court.

The program-design table also says recreational U9–U10 uses modified small-sided games rather than formal games.

What Game Format Is Used at U9–U10 Competitive?

Competitive U9–U10 also uses:

4v4 or 5v5

The game format is the same as recreational U9–U10.

What Game Format Is Used at U11–U12 Recreational?

Recreational U11–U12 uses:

4v4 or 5v5

The court format remains cross-court.

This gives the recreational environment flexibility to continue using a smaller-sided format at U11–U12.

What Game Format Is Used at U11–U12 Competitive?

Competitive U11–U12 uses:

5v5

This is the first category in the Youth Rules Guidelines where 5v5 is the only listed game format.

The competitive U11–U12 environment also moves to a full court.

What Game Format Is Used at U13–U14 Recreational?

Recreational U13–U14 uses:

4v4 or 5v5

This is notable because the recreational pathway continues to allow 4v4 even at U13–U14.

The court itself is full court at this age.

What Game Format Is Used at U13–U14 Competitive?

Competitive U13–U14 uses:

5v5

U11–U12 competitive

It remains the only listed format for:

U13–U14 competitive

When Does 4v4 Basketball End?

The guidelines do not remove 4v4 from every pathway at the same age.

Competitive pathway

4v4 remains an option at U9–U10, but competitive U11–U12 and U13–U14 move to 5v5.

Recreational pathway

4v4 remains an option through:

Recreational U13–U14 is full court but still allows either 4v4 or 5v5.

How Does the Game Format Progress by Age?

The overall progression is:

U7–U8
3v3 or 4v4
