Basketball Coaching Toolkit
The Basketball Coaching Toolkit is a FIBA-geometry court (28 × 15 m, 6.75 m three-point arc with 0.9 m corners) for drawing reads and counters, plus a drill library, session planner, fitness timers and a match desk that keeps shooting denominators honest. Select a player to see whether a shot from that spot is worth two or three.
How to use this calculator
- Start on the Tactics tab: the board opens with an illustrative Basketball example, drawn to scale in metres. Drag tokens, or select one in the object list and move it with the arrow keys.
- Use Run, Pass, Carry and Screen to draw movement: click a token, then where it goes (for a pass, click the receiver). Set timings and an instruction in the inspector.
- Add scenes with 'Continue to new scene', and add branches for what happens when the opposition or context changes. Play a scene or the whole sequence; captions and a transcript follow along.
- Open a starter drill from the Drills tab, plan sessions (including parallel stations) on the Training tab, time fitness work on the Fitness tab and keep a match record on Match day.
- Export a PDF, SVG, PNG or .zcoach file. Exports are anonymised unless you choose to include names, notes or results.
How it works
Everything on the board is stored in real field units, not screen pixels: the board scales uniformly to fit, and rotating or zooming the view never changes a stored position. Field markings are generated from geometry, so fixed-size markings keep their size on a custom field.
A playbook is a graph of scenes joined by labelled branches. Paths move tokens at constant speed along their length; a pass carries the ball to its receiver, and a warning appears if the receiver will not be there. A loop must have a repeat limit before it can play or export.
Shot value comes from the court geometry: beyond the arc or in the corner channel is three, and the foot-on-the-line option counts it as two.
Effective field-goal percentage is (made + 0.5 × threes made) ÷ attempts; with no attempts it shows no data.
Playbooks branch on the defence's response — a switch, a denied cut, a protected rim — so the counter is part of the plan.
Your work saves automatically in this browser about half a second after each change, with undo for the last 100 edits and the last 20 saved revisions kept. A board changed in another tab is never overwritten silently — you can keep yours as a copy.
Worked example
Worked example: eFG% and points. 8 field goals made, 3 of them threes, from 20 attempts: (8 + 0.5 × 3) ÷ 20 = 47.5% eFG. Four twos, three threes and two free throws: 2 × 4 + 3 × 3 + 2 = 19 points.
Common mistakes
- Mixing free throws into field-goal attempts. They are recorded and reported separately.
- Comparing percentages built on very different numbers of attempts. The summary always shows the made/attempted counts next to the percentage.
- Sharing a named export by accident. Exports leave out names, notes and results unless you tick them in, and anonymising removes them from the file rather than hiding them.
Frequently asked questions
Where does the three-point line meet the corner line?
On a 15 m-wide FIBA court the 6.75 m arc meets the straight corner lines 0.9 m in from each sideline, about 2.99 m from the baseline: 1.575 + √(6.75² − (7.5 − 0.9)²) metres. The board draws it from that formula, so a custom court stays consistent.
Is my team's information uploaded?
No. Boards, rosters, sessions, results and matches are saved only in this browser on this device, with no account. Anyone using the same browser profile can see them, and clearing site data removes them — download a backup from the Library tab if they matter.
Are the drills and plays official?
No. The Basketball starter drills and playbooks are original teaching examples written for this toolkit and still awaiting review by qualified coaches. They are a starting point, not a complete curriculum, and contact is none by default.
Does the toolkit apply the rules of my competition?
It draws field markings from published geometry and keeps every competition-dependent value — scoring values, period lengths, interchange limits — as a setting you confirm. Advisories (legal areas, offside position, retreat lines) are teaching overlays, never a referee's decision.
Can I share a play with my team?
Yes, by file: export a PDF or image for players, or a .zcoach file another coach can import. An imported file opens as a new copy and never overwrites your work. There is no hosted team link.
Is the shuttle timer a beep test?
No. It is a custom paced shuttle you configure — lane length, speeds, shuttles and recoveries — and it is labelled as not a standardised test. Named standard tests stay switched off until their exact timing, rules, edition and reuse rights are verified, and no VO2 or fitness ranking is produced.
