How to Mark a GAA Pitch | Step-by-Step Guide Ireland

A well-marked GAA pitch is the foundation of a great game. This step-by-step guide covers everything you need to mark a GAA pitch correctly — from measuring out to applying the final line.

What You Need

GAA Pitch Dimensions

A standard GAA pitch (Gaelic football and hurling) measures:

  • Length: 130–145 metres
  • Width: 80–90 metres
  • End zones: 14 metres deep from the goal line
  • 45-metre line: 45 metres from the goal line
  • 65-metre line: 65 metres from the goal line (hurling only)
  • Penalty spot: 11 metres from the centre of the goal
  • Goal area: 4.5 metres from each post
  • 21-metre line: 21 metres from each goal line

Step-by-Step Guide to Marking a GAA Pitch

Step 1 — Prepare your paint

If using a concentrate paint, mix thoroughly before filling your machine:

  • Clubline White: 2.5L paint + 4L water per pitch
  • Lumen White: 2L paint + 4.5L water per pitch
  • Extreme White: 1.5L paint + 5L water per pitch

If using a ready-to-use paint (Edge, Direct, Ecoline+), fill directly from the container — no mixing required.

Step 2 — Mark out the goal lines

Start by establishing the two goal lines at each end of the pitch. Measure the full length of the pitch and hammer in pegs at each corner. Run a string line between the corner pegs to define the goal line. Check squareness by measuring diagonally corner-to-corner — both diagonals should be equal.

Step 3 — Mark the sidelines

Run string lines along both sidelines connecting the four corner pegs. The pitch should now have a clear rectangular outline. Double-check width measurements at several points along the pitch to confirm parallel sidelines.

Step 4 — Mark the 21-metre lines

Measure 21 metres infield from each goal line and mark across the full width of the pitch. Use string lines to ensure perfectly straight lines.

Step 5 — Mark the 45-metre lines

Measure 45 metres from each goal line and mark across the full width of the pitch.

Step 6 — Mark the 65-metre lines (hurling only)

For hurling pitches, mark the 65-metre lines 65 metres from each goal line across the full width of the pitch.

Step 7 — Mark the midfield line

Measure the exact midpoint of the pitch and mark a line across the full width.

Step 8 — Mark the goal areas

At each end, measure 4.5 metres from each goalpost along the goal line. From these points, measure 4.5 metres into the pitch at right angles to mark the corners of the goal area. Connect these points to form the rectangular goal area in front of each goal.

Step 9 — Mark the penalty spot

Measure 11 metres from the centre of each goal, directly in line with the centre of the goal, and mark a penalty spot.

Step 10 — Apply the paint

Using your spray marker or transfer wheel machine, follow each string line carefully. For spray markers, maintain a consistent height and speed for uniform line width. For concentrate paints, use a Green Flat Fan Nozzle (F110-015). For Extreme White, use a Yellow Flat Fan Nozzle (F110-020).

Step 11 — Remove string lines and inspect

Once all lines are applied, remove string lines and stakes. Walk the pitch and touch up any gaps or missed sections while the paint is still wet if possible.

Tips for Perfect GAA Pitch Lines

  • Mark on dry grass where possible — wet grass reduces paint adhesion
  • Mark in dry weather or allow 1–2 hours before rain is forecast
  • For county standard pitches, use Lumen or Extreme for brighter, longer-lasting lines
  • Re-mark lines weekly during the playing season for best appearance
  • When switching from football to hurling lines (or vice versa), use Line-Out green paint to cover unwanted white lines
