    What are the two 6 inch lines just toward the baseline from the free-throw line and inside of “the paint” for? they seem to be aligned with the edge of the free-throw circle closest to the baseline. What rule are they intended to be associated with?
    Thanks, Paul

      Paul,

      We have done extensive research and are finding that these lines are not consistently used throughout the entire sport of basketball (high school, college; women’s, men’s; etc.), and I’m not showing a specific name. If I happen to come across this I will pass along the information. Great question!

    What is double foul ?

    • Alicia Schilke on December 6, 2019 at 9:52 am

      When two fouls are committed at the same time by opposing players against each other. The penalties offset each other, but both players are charged with personal fouls.

    Paul, the two lines inside the key (aligned with the edge of the free throw circle) help mark the top of the Lower Defensive Box (LDB). The hash marks on the baseline mark the sideways extent. This otherwise unmarked region is mentioned a bit in the NBA rulebook for eligibility of certain fouls.

    The 5′-3″ offset of the three point line from the outer boundary line of the court is ambiguous. It should be 3′-0″ from the side outer boundary line.

      Thank you for the feedback. Recreation Unlimited will definitely take this into consideration.

    Do you have the sizes with the out of bounds part of the court included in the full dimensions? Like the dimensions of the full slab?

    • Alicia Schilke on March 9, 2020 at 4:21 pm

      John,

      That’s a great question! We don’t provide the exact concrete slab measurements nor do we provide the actual work of laying the concrete or designing courts. However, we do our best to provide tools such as the basketball court diagram blog for our basketball goal customers. I hope this helps! Have a great day.

    On the last diagram of the high school basketball half court, the vertical/short size says 50′ and the horizontal/long side says 47′. Are those measurements flipped? Or is the horizontal line really supposed to be 3′ shorter than the vertical line (it looks longer)? Thanks!

  8. Molly Campbell on June 10, 2020 at 2:57 pm

    Hi Smurti, thanks for your comment, and good eye! The optimum width of the court is 50′, and the half court length is 47′, so yes, it is 3′ shorter. The last diagram you’re referring to is not 100% to scale, so that is the reason for the discrepancy.
