Tactical board symbols and conventions

Why a fixed code matters

During a five-minute team talk, nobody should be wondering whether a dashed line is a pass or an off-ball run. When the code is stable, attention goes to the tactical idea instead of the drawing. That's why a few conventions used consistently beat many used half the time.

The three basic lines

Most invasion sports share three symbols, although the details vary between coaching schools:

• Solid arrow: a player moving without the ball (a run, a cut, a recovery).
• Dashed line: the path of the ball — a pass. Near-universal in basketball; some football coaches use it the other way round, which is exactly why you should fix it.
• Wavy or zigzag line: a dribble — the player travels with the ball.

Players: numbers, colours and roles

The two teams must be distinguishable at a glance. Pick colours with strong contrast against each other and the background, and avoid relying on red versus green alone, which many colour-blind people confuse. If you export for black-and-white printing, the Clean field style with a light team and a dark team works better than two saturated colours.

Number by position rather than shirt number when you're explaining a system: 1 (point guard) to 5 (center) in basketball; by role in volleyball (setter, opposite, middles, outsides, libero); and in baseball the classic position numbers from 1 (pitcher) to 9 (right fielder), which are also how plays like the 6-4-3 double play are scored. For a specific match plan, real shirt numbers help each player find themselves quickly.

Zones: space, not decoration

A shaded zone should mean one thing per board: the space you want to occupy, the space you want to deny, or the area where the press is triggered. If you use two zones with different meanings, give them different colours and a short label. Large, semi-transparent zones read better than many small ones because the eye groups them into a single idea.

Text: short labels, not paragraphs

Text on the board is for naming, not explaining. "Trigger: back pass", "2v1", "Help" or "Offside line" are useful labels. If you need a full sentence, that explanation probably belongs in the spoken talk or the drill description.

Order and sequence

When a play has several actions, order matters more than the strokes. There are two ways to show it:

• Number the actions with small labels (1, 2, 3) next to each arrow. Works on a printed image.
• Use animated steps: each step shows only the action happening at that moment, and playback shows the full play. It's the clearest option on screen, and export uses the active step, so you can produce one image per phase.

Sport-specific conventions worth respecting

• Basketball: a screen is drawn as a short line perpendicular to the end of the screener's movement; mixing it up with a cut confuses any trained player.
• American football: receiver routes are drawn from the line of scrimmage and offensive-line blocks as short strokes ending in a bar. Defenses are described by their coverage (Cover 1, 2, 3, 4).
• Volleyball: each player's starting spot depends on the rotation, so draw where they stand at the moment of the serve first, then the movement to their playing zone.
• Rugby: the offside line at a ruck or maul shapes the whole defensive picture; mark it with a line before drawing the defence.

A starter code for your team

1. Pick one colour per team and keep it all season.
2. Decide what is a pass and what is a run (most common: dashed for passes, solid for runs) and write it on the first board you show.
3. Reserve red for the final action (shot, attack, finish).
4. Use at most two zone colours per board.
5. One idea per board: if there are two, make two boards or two steps.
