American Football (Gridiron) Coaching Toolkit
The American Football (Gridiron) Coaching Toolkit draws a 100-yard field with 10-yard end zones and professional hash marks for building routes, coverages and call-sheet plays. Down and distance draw the line of scrimmage and the line to gain, personnel counts are checked, and the toolkit adds non-contact drills, a session planner, fitness timers and a match desk.
How to use this calculator
- Start on the Tactics tab: the board opens with an illustrative American Football (Gridiron) example, drawn to scale in yards. 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.
Down and distance clamp at the goal line: with 10 yards to go from the opponent's 4-yard line, the label is goal to go and the target cannot pass the goal line.
More than 11 players of one side on the board is flagged before you export a lineup.
All diagrams are non-contact; there are no tackling or live-rush drills.
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: field length. The field of play is 100 yd and each end zone 10 yd, so the diagram is 120 yd — 109.728 m. 100 yd alone is 91.44 m.
Common mistakes
- Using one league's rules as universal. Hash width, timing and scoring details vary by level; the toolkit labels its geometry baseline and leaves rules to your competition.
- Exporting a play with 12 players in the active unit. Fix the warning first.
- 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
What is goal to go?
When the yards needed for a first down would reach or pass the goal line, the line to gain is the goal line itself and the down is described as goal to go. The board shows this automatically from the ball spot and distance you enter.
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 American Football (Gridiron) 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.
