Reading Ice Hockey Diagrams

Overview

In a rink diagram a circle is a forward and a triangle is a defenceman, while an open glyph is your own team and a solid one the opposition. A goaltender is a bare G with no shape around it, and an X is a pylon — a practice cone, never a player. So shape tells you what a player is and fill tells you whose side they are on: a winger is a circle whether they are attacking or backchecking, because the shape follows the player rather than the moment. That is one published key's convention, and the other cited below uses the same two shapes for the two teams instead — which is the first thing to know if you meet a diagram from somewhere else. Colour carries nothing in the player glyphs or the line symbols, which is why they still work printed, photocopied or in either theme. The shaded regions described further down are the single exception — a region drawn as a hazard is tinted red rather than blue, a difference greyscale loses, so their captions say in words which one they mean. And where a caption says a detail is a coaching choice, believe the caption rather than the picture: a diagram is the most absolute-looking thing on a page, and it shows one moment of one system among several. You do not need to memorise the rest; come back when a symbol is unfamiliar.

The notation is drawn from two published symbol keys, and one symbol is compared below against a third source that is a coaching manual with its own house key, not a governing-body one. The two keys disagree in places, so it is worth two minutes to know which is which.

Where each symbol comes from. Six line symbols are drawn the same way in both keys: forward skating, skate and stickhandle, passing, shooting, the drop pass and the two-bar mark. The two keys often differ on what to call a symbol even where they draw it identically — the wave is skate and stickhandle on one and skating with control of the puck on the other, and the two-bar mark is a sudden stop on one and stopping on the other. Where this guide had to pick one name in public, the bullets below say which. Backward skating is not one of them: the Hockey Eastern Ontario sheet draws it as a tight wave, and the IIHF key draws it as a row of separate overlapping arches, flatter than they are wide. These diagrams follow the IIHF key. The rest:

• A line ending in two bars is a sudden stop — the IIHF key's name for it, and the one the key above uses. The Hockey Eastern Ontario sheet draws the same mark and calls it stopping, so the two keys agree on the glyph and differ only on the name. The IIHF key's plain stop, a pair of slashes, is a different mark and is drawn here too.

• A line ending in one bar is not used here at all, and that is deliberate. It means checking pressure on the Hockey Eastern Ontario sheet, and the IIHF key has no such symbol — one bar is half of its two-bar sudden stop, and a second published meaning exists — a coaching manual whose key gives the same mark as screen, pick, or block (Johnston & Walter, Hockey Plays and Strategies, 2nd ed., 2019). One mark, two published meanings and one published key that does not define it at all. Draw a one-bar route for pressure and an IIHF-trained reader sees a player stopping where you meant a player closing. It is the clearest reason on this page not to assume a key you meet elsewhere matches this one.

• A route that closes on an opponent ends in the two-bar mark, not an arrowhead, and that is the one place these diagrams knowingly draw one glyph for two things. The two-bar mark is the sudden stop above; a pressure route also ends in it. The reason is that the two marks have to be told apart by where the route finishes rather than by their shape. An arrowhead reads as continuing past the point the line ends at; the bars read as ending there. Where that end point is an opponent rather than open ice, read the bars as arrive under control, and the destination and the caption carry the rest.

• Bars across a line are lateral crossovers — the one line symbol here taken from the Hockey Eastern Ontario sheet rather than the IIHF key, because the IIHF key has no lateral-crossover symbol at all. (The player glyphs come from that sheet as well; it is the line symbols that are mostly the IIHF key's.) It is kept, where the one-bar pressure glyph was not, because a barred line collides with nothing in the IIHF key, so it cannot be read as some other symbol. The published glyph is a bare picket of bars with no line through it and no direction; the arrow and the line are added here, because a picket that does not say which way you are going is no use in a play diagram. The IIHF key's nearest equivalent is a different shape again.

• Dropping the puck follows neither key. Both draw it as a wave — the carrier skating with the puck — then a marker, then a straight line and an arrowhead. These diagrams draw the marker and the straight line without the leading wave, so the mark shows the drop and not the carry that set it up. It is this guide's own version.

Shaded regions and faint dashed lines are this guide's own, and neither published key has anything like them. Many diagrams here wash an area of the ice in a light tint with a thin dashed edge, usually with its name written inside it — the slot, the house, home plate, the box, the passing lane. Neither key defines an area symbol of any kind: the Hockey Eastern Ontario sheet's seventeen rows are players, lines and a cluster of pucks, and the IIHF key's list runs from forward skating to body check with no region mark in it. So this one is a house convention rather than a borrowed symbol, and four things are worth knowing about it.

First, the tint is not paint on the ice unless the caption says it is. The slot, the house and the high slot are names for regions rather than markings, and Rink Map is where their edges are defined. The edge is drawn thin and broken on purpose so that it cannot be taken for a line on the rink. The trapezoid is the exception — that one really is painted, and its caption says so.

Second, the shading does not tell you whether the region is somewhere to go or somewhere to stay out of. The caption does, and the diagrams here use it both ways: a shaded box marks the ice a centre is heading for in one picture and the ice a pass must never cross in another. Where the region is a hazard it is tinted red rather than blue, and that is the one thing in this notation carried by colour alone — at a light wash the two tints are nearly identical in greyscale or a photocopy, so the caption is what you should be reading.

Third, drawn between two points with no tint at all, the same mark is a line rather than a region: faint, dashed, with a short name beside it. It marks something you need to see that is neither on the ice nor a route — the royal road, or the shooting lane a defenceman had a second ago before an opponent stepped into it. Nothing travels along it and nobody skates it; it is there so you can see what someone else is set up for.

Fourth, where one region is tinted more heavily than another in the same picture, the strength of the tint is a ranking rather than a second symbol. The map of what a mistake costs in Risk Management grades ice by how expensive a turnover there is. It marks five regions: four in red and one in blue, and the four reds carry only three strengths, because two of them are deliberately identical. ⚠️ That equality is the picture's teaching rather than an oversight — the middle of the neutral zone is shaded exactly as heavily as your own end, because a mistake in the two costs about the same — so do not expect four distinguishable reds and do not try to rank them by eye. Nothing new is being said with colour — red is still the hazard tint and blue still the ice you want — but the depth of the red is carrying an order, and neither published key has anything of the sort. ⚠️ Read that order out of the caption, not off the page. A light wash is a poor ranking device: the tints are close together by design, greyscale and photocopying compress them further, and where a red region has to be compared against a blue one the order inverts outright, because a light blue prints darker than the faintest red. So a graded picture names its regions in order in words, and the words are the part to trust.

Shape is the position. The International Drill Symbols sheet gives it in two lines — "● ○ Forward / Player" and "▲ △ Defender / Player" — so a circle is a forward and a triangle is a defenceman, and that stays true of a player from one picture to the next. A goaltender is a bare G. Both keys offer that form — though the IIHF key also carries a goaltender a second way, as the numeral 1 inside a team glyph, which is the convention this guide does not use. No shape is wrapped round the letter here because a circle would say forward and a triangle would say defenceman.

Fill is the team. An open glyph is your own team and a solid one the opposition. The key prints a solid and an open version of each player row without saying what the difference means — "● ○ Forward / Player" could as easily be read as solid-is-a-forward and open-is-any-player — so reading that pair as the two teams is this guide's doing rather than the key's. So both facts are in every picture: the shape tells you what a player is, the fill tells you whose side they are on. Neither depends on colour, so neither is lost in greyscale, in a photocopy, or to a reader who does not see red and green apart.

Which side has the puck is not carried by the shapes at all — the puck is drawn, and the caption says the rest. It is a small solid dot, about a third the width of a player, and it is this guide's own mark: neither key publishes a symbol for a single puck. Keep it apart from the marker on a drop-pass line, which is the same ink and sits on a route rather than beside a player.

Two departures on top of that, so you are not caught out:

1. The letters inside a glyph are roles, not positions. The IIHF key puts a numeral inside — 1 goaltender, 2 right defence, 3 left defence, 4 right wing, 5 centre, 6 left wing. They are not used here, because F1, F2 and F3 are roles set by order of arrival and not people, and a numeral would say "F1 is the centre" where the text takes care to say it is not. So the glyph carries whatever label the surrounding section uses. One of those labels collides: a circled C means coach on both published keys, and here it means a centre. No diagram in this guide draws a coach, so nothing is ambiguous on the page — but on someone else's diagram a circled C is the person on the bench.
2. Reading fill as the team at all is this corpus's choice, and so is which fill means "you". The key prints both a solid and an open version of every player row without saying what the pair is for — it could as easily mean solid-is-a-forward and open-is-any-player — and it has no opposition symbol of any kind. Here open is yours and solid is theirs.

And one thing that is almost not a departure: the player glyphs and the line symbols are monochrome, and none of the keys consulted separates the teams by colour either. That is agreement, not invention. It is done so that a printed page, a photocopy and a reader who does not see red and green apart all get the same information as the screen — which holds for every symbol here except the red tint on a hazard region, where the caption has to carry the warning instead.

Numbered tags say what happened first, and they count routes rather than players. A still picture cannot say whether the pass beat the forechecker or the forechecker beat the pass, so where the order matters each route carries a small numbered tag a short way along it. The numbers run in the order the things happen. They are never a player's name and never sit inside a player's shape, which is where the letters go — and like the shading, the tag is this guide's own and appears in neither key.

What a diagram is and is not. A diagram shows one moment. A movement that only makes sense over time needs two diagrams, so where you see a pair, read them as a sequence or as two answers to the same instant — the captions say which. And a picture is the most absolute-looking thing on a page: where a caption says a detail is a coaching choice, believe the caption, not the picture.

Common Mistakes

• Reading a diagram as the way hockey is played. A picture is the most absolute-looking thing on a page. Almost every diagram here shows one system among several, and the caption says so — believe the caption.
• Taking a shape as a place to stand. Positions in a diagram are drawn at one instant. Where the play moves, the shape moves with it.
• Assuming a key you meet elsewhere means the same thing. The two shapes are the biggest trap: a circle is a forward here and the attacking team on the IIHF's own key, so the same picture reads two ways. One mark — a line ending in a single bar — is checking pressure in one published key, half of a sudden stop in another, and screen, pick, or block in a coaching manual. Check the key in front of you before you read the picture.
• Assuming your coach uses these symbols. Nothing here has been checked against how any particular club draws things. If your coach's whiteboard disagrees, their whiteboard wins.
• Taking a shaded region for a marking on the ice. The slot, the house and the rest are names for areas, not paint; go and look at a rink and there is no line marking any of them out. The trapezoid is the one shaded region in these diagrams that really is painted, and its caption says so.
• Ranking regions by how dark they look. Where a picture grades ice by tint, the order is in the caption. Comparing the washes by eye fails in greyscale, on a photocopy and on e-ink, and it fails in colour too the moment a red region has to be set against a blue one.
• Expecting a diagram to show a whole play. One frame shows one moment. Where a movement only makes sense over time you will find two diagrams, and the captions say whether they are a sequence or two answers to the same instant.

Key Takeaways

1. A circle is a forward; a triangle is a defenceman; a goaltender is a bare G. An open glyph is your own team; a solid one is the opposition. Shape and fill carry different facts, so the diagrams work in either theme, in print and in greyscale. A player's shape does not change when play turns — a winger is a circle backchecking as well as attacking. Reading fill as the team is this guide's own convention — the key prints the pair and never says what it is for — so on another diagram open and solid may mean nothing at all. ⚠️ The IIHF's own key uses these two shapes for the two teams instead, with the position as a numeral inside, so do not carry this reading onto one of its diagrams.
2. An X is a pylon — a practice cone — and never a player.
3. Solid arrow, forward skating. Long smooth wave, skate and stickhandle. A row of overlapping flattened arches, skating backwards — each arch is a C-cut, the half-circle a skate carves to push backwards, turned on its side and repeated — and a sharp zigzag, backward crossovers. Dashed arrow, a pass. Double line, a shot. A line ending in two short bars is a route that stops where it ends — the mark used where a player closes on an opponent, and the one to read as arrive under control rather than carry on through. Those cover most of what you will meet.
4. A tinted area with a dashed edge is a named region of ice, and the same mark between two points with no tint is a line that is not on the ice. Neither published key has either one, so both are this guide's own. The tint never says whether the region is somewhere to go or somewhere to keep out of — the caption does, and it is the caption that carries the warning where one is tinted red. Where a picture tints regions at different strengths, that is a ranking — and the ranking is in the caption's words, because the shades themselves do not survive greyscale, a photocopy or a comparison across the red and blue tints.
5. A small numbered tag on a route says what happened first. It counts routes in order, never players, and it never sits inside a player's shape.
6. The letters inside a glyph are roles, not positions. F1 is whoever arrives first, not the centre.
7. Where a caption says a detail is a coaching choice, it is. Ask which version your team runs rather than taking the picture as the answer.
