A surveyor sets one back line first, finds its midpoint, and runs a perpendicular across the full 55.00 metres. Every other line, every arc and every corner squares back to those two references. Start from a touchline that happens to be already marked on site and a pitch finishes out of square by a metre at one corner.
Our guide to hockey turf is built on that order of work. It treats dimensions as a checking exercise rather than a drawing detail. We tuft grass rolls on our own line. That is why we read layouts the way a scheduler reads them: field of play, run-off, markings, goals, orientation, surface type, then roll and seam positions. Every number below carries a published source.
Field of Play and Its Two Boundary Edges
A hockey pitch is rectangular. The two longer edges are the side lines. The two shorter edges are the back lines, and the middle section of each back line between the goalposts is the goal line. The side line measures 91.40 m and the back line measures 55.00 m, which gives a field of play of 5,027 m2 before any run-off is added.
Two conventions decide whether your measurements agree with everyone else’s. First, every dimension is taken to the outside edge of the perimeter lines, because a line belongs to the area it encloses. A ball on the side line is still in play, and a ball on the circle line is still inside the circle.
Second, all line markings are 75 mm wide. That single figure is why a paint estimate works from centre paths while a layout drawing works from the outside rectangle. A check that mixes the two drifts by half a line width at every edge. Any guide to hockey turf has to state the reference before it quotes a number. The published rules behind these figures are set out in the reference description of the hockey pitch and its markings.
These are the numbers that carry through to every later decision, including roll width. Our hockey turf systems for club and school pitches are specified against a field of play that has already been fixed on paper. It is the same order most artificial turf installations follow once a client arrives with a drawing rather than a wish.
| Measurement | Value | What it bounds |
|---|---|---|
| Side line length | 91.40 m | The long perimeter edge |
| Back line length | 55.00 m | The short perimeter edge, with the goal line at its centre |
| Field of play area | 5,027 m2 | Playing surface only, before any run-off |
| Line width | 75 mm | Every painted line on the field |
| Reference point | Outside edges | Dimensions are taken to the outer edge of each line |
Run-Off in Two Layers Not One
Run-off is where most facility plans come unstuck, and the reason is that the rules ask for two things at once. The playing surface must continue past the lines by a set distance. Beyond that surface there must be unobstructed clear space. A fence placed two metres behind the back line satisfies neither requirement on its own.
Read as a single figure, run-off is ambiguous. Read as two layers, it is simple arithmetic. Behind each back line the surface extends at least 2.00 m, with 1.00 m of clear space beyond it, for a minimum total of 3.00 m. The recommended figures are wider: 3.00 m of surface plus 2.00 m of clearance, giving 5.00 m in total. Across artificial turf installations of every size, this is the pair of numbers that gets collapsed into one.
