ok, I looked at the diagram. I understand most of it, but i didn't see the dimensions for the big outside radius almost the width of the courts. and what is the meaning of the 18ft. with the "19ft. to center of circle. I understand it looks like the 18ft. is explaining the distance from the edge of court to the 2" line behind 6ft. radius, but what is the 19, because it looks like the distance from the point of the line across the 12ft width just behind the 6ft. radius to the huge radius at court edges is more than 1ft. away... Thanks.

ok, i spoke to soon... the outside line would have to be a 24ft. radius i believe, taking the length of 18ft. plus the 6ft. radius line... what is the 19ft. to center of circle?

The big circle is the three point line. The center of the radius is under the center of the basket and the length is so that it exactly intersects the top of the key. Note that the last four feet on either end are straight. I might have sent you to a drawing that has a mistake on it. I don't know what the 18' is. The free throw line is 15' from the face of the backboard, and the face of the backboard is four feet from out of bounds. Add together, and that's 19 feet.

ok, now how do you square up the the 12 feet width out to 19ft. to insure a 90 degree...i could come up with something, but is there a different technique for the basketball court.

Create a line that is 90 deg from the line connecting the goals. Square it up using either 3,4,5 method or bisect the angle method. What's different about a court is, you want to confirm that all is square by measuring diagonally from corner to corner and making sure they are the same before painting.

Here's how I did them,. backboard to foul line 15ft( inner edge of the 2" line. put a mark there,I use a roofing nail.Take a rule and go 6 ft on each side with a chalk line. Measure 2"off chalk line and tape, this is your 2" foul line. Using the center nail, take a tape measure and go away from the hoop and mark @ 6ft and 6.2 ft. Go on each side and mark 6 and 6.2 in a tight formation, this will give you the half circle atop of foul line.The box is 12ft across inside 2" line. 12.2 outside 2"line. Find the center of hoop, drive in a nail. Take a rule and measure 19.9 ft outwards. this should take you atop of the foul line circle.Again using the nail @ center hoop go in a tight formation and mark @ 19.9 and 19.11, this gives you the 3pt arch. do both sides if full court. Now find out how long the court itself is. 74 ft high school, 84 ft colledge, 94 ft pro. Pro courts have a different style box and 3pt arch.( longer distance from hoop). Hope it is 84 ft. Find center of court, drive in a nail. take ruler and in a tight formation make a circle by marking @ 6ft and 6.2ft. Same with the 2ft inner circle. mark @ 2ft and 2.2ft. now tape off. Remember the tighter the marks, the easier to make a circle.

I drop a plumb bob from each backboard, connect them with a line, square up and mark the half court line. and work everything else off of that. I can't belive anyone still tapes by hand. I just snap a chalkline, and follow it with my Sport Taper. circles are easy. Set the centerpoint down at the right place, adjust the length to the proper distance, and push it around. http://www.parkinglotplanet.com/sport_taper.htm

Robert, I bought one of those tapers from you and it's missing parts. I still haven't heard back from you.

you will today

Is the taper adjustable? If so, what are the widths?

Taper goes from a little less than two inches, to a little more than four inches in width.
