There are two side lines of 16m, two base lines of 6m and two dead zone lines of 6m. There is no centre line that divides the court into equal left and right service courts.
The lines should be 4-5cm in width and contrast sharply to the colour of the surface. For sand and natural grass surfaces, boundary lines should be ribbons made of resistant material.
A bungee cord should be attached to each corner and connected to a buried anchor disk.
The bungee will provide the tension necessary to keep the boundaries in place while giving the flexibility to minimise the chance of injury should a player catch their foot under the line.
For concrete and asphalt surfaces, boundary lines should be a tape made of resistant material that sticks firmly to the ground or they can be marked/painted directly on the surface.
