Roller Derby Track Dimensions | Official Measurements for Fair Play

Roller derby track dimensions can vary. Roller derby tracks are round, forming an approximately oval-like circuitous path similar to the track of NASCAR. The measurements can vary slightly based on different leagues and regulations, but generally, the length of the track’s perimeter ranges from around 100 to 110 meters. The track is encircled by two main lines: the “Jammer Line” and the “Pivot Line.” These lines define where the pack starts at the beginning of a jam.

One more line takes center stage –the “Jammer Line” is where jammers (the point scorers) start each jam. The pivot line is where the pivots, blockers, and everybody else line up.

Let’s discuss the roller derby track dimensions in detail.

How big is the derby?

According to the WFTDA guidelines, the track’s length is 108 feet (32.92 meters). However, it’s essential to note that this length includes a 10-foot (3.05-meter) Outer Officiating Lane.

The Outer Officiating Lane

The Outer Officiating Lane is a designated area for officials to carry out their duties. Alongside the track’s total length of 108 feet (32.92 meters), a 10-foot (3.05-meter) Outer Officiating Lane is marked out. 

Derby Track Width

The official roller derby track’s width measures 75 feet (22.86 meters). Similar to the length, this width includes a 10-foot (3.05-meter) Outer Officiating Lane.

The 5-Foot Outer Officiating Lane

While the standard dimensions include a 10-foot Outer Officiating Lane, the WFTDA acknowledges the potential for variations under specific circumstances. If an acceptable barrier is in place, teams can utilize a 5-foot (1.52-meter) Outer Officiating Lane. 

Materials and Markings

Boundary Material

Rope or raised boundary material is a fundamental element of the track. The diameter should fall within the range of ¼ inch to ½ inch (0.6 cm – 1.3 cm), providing a sturdy and visible boundary.

A minimum length of 385 feet (118 meters) is required, and it must be secured firmly to ensure its integrity during the intensity of the matches.

Tape for Track Markings

Tape is used to create track markings, including boundary lines and other essential designations. The tape should be 1 to 3 inches wide (2.6 – 7.5 cm), providing clear boundaries. A minimum of 500 feet (155 meters) length is recommended, with additional tape on hand for repairs and maintenance.

  • Length: 108 feet (32.92 meters)
  • Outer Officiating Lane: 10 feet (3.05 meters)
  • Width: 75 feet (22.86 meters)
  • Outer Officiating Lane (with acceptable barrier): 5 feet (1.52 meters)

Roller Derby Track Elements and Their Dimensions

Start Line

The start line marks the beginning of each jam – the intense period of gameplay in roller derby. It is positioned at the inner edge of the track, perpendicular to the straightaways, and stretches the width of the track (26 feet or 7.92 meters). This line is where jammers and blockers begin their positions as the whistle blows to initiate the jam.

Pivot Line

The pivot line is located ahead of the start line, the pivot line is a crucial reference point that influences the positioning of blockers. It also runs across the entire width of the track (26 feet or 7.92 meters). Blockers line up behind the pivot line, strategizing their initial formation and defensive tactics.

Jammer Line

The Jammer line is positioned a specific distance behind the pivot line, and the Jammer line designates the starting point for the jammers – the players aiming to score points by lapping opposing team members. The jammer line is set 30 feet (9.14 meters) back from the pivot line, providing a strategic buffer that allows both teams to arrange their formations effectively.

Turn Boundaries

There are four turn boundaries, each with a distinct radius:

First and Third Turn Boundaries: These curves feature a radius of 26 feet (7.92 meters), which maintains consistency with the overall width of the track.

Second and Fourth Turn Boundaries: These curves have a slightly larger radius, measuring 28 feet (8.53 meters). 

Coach Area

The Coach Areas are designed to accommodate additional team support staff. These areas are located outside the Referee skating lane, specifically in Turn 2 and Turn 3.

Each Coach Area comprises two boxes measuring approximately 2 feet by 2 feet (0.6 meter by 0.6 meter). These little areas allow team support staff to interact with their athletes.

Roller Derby Penalty Box Dimensions

The Penalty Box resides along the straightaway that connects Turn 4 and Turn 1 – the stretch between the Jammer and Pivot Lines. It’s strategically positioned between the designated team areas, facilitating swift access for penalized skaters.

While the exact size of the Penalty Box may vary based on venue constraints, its design caters to functionality and efficiency. Ideally, it should be spacious enough to accommodate six chairs – three for each team. 

To stand behind the seats, the space should be allotted for Non-Skating Officials (NSOs) handling Penalty Box duties. The optimum depth for the Penalty Box is 10 feet (3 meters), allowing room for skaters to serve their penalties comfortably.

A minimum of 5 feet (1.5 meters) is maintained between the front of the chairs and the nearest border of the Penalty Box, which also functions as the outer boundary of the Referee skating lane.

FAQs

The Derby track dimensions vary: 108′ x 75′ (8,100 sq. ft.) officially, and with 5′ clearance, 98′ x 65′ (6,370 sq. ft.).

The playing area is defined by a straightforward rectangle measuring 108 feet by 75 feet (32.92 meters by 22.86 meters). This rectangle is divided by a center line running its length, with 54 feet (16.46 meters) marked on each side of the center line.

The official derby track spans 108 feet by 75 feet, giving us 8,100 square feet. Now, if we consider a minimum o f5 feet clearance on the outside, that space shrinks to 98 feet by 65 feet, equaling 6,370 square feet. 

A clearance lane of 10 feet (3.05 meters) is needed to ensure enough room to roll and rock. So, the space measures 75 by 108 feet (22.86m x 32.92m), which adds up to 8,100 square feet (752.51 square meters). Wrapping it up neatly takes about 385 feet (117.35 m) of rope or something similar to create those boundary lines. Now, if we look at the whole package, including the infield, it’s sized 55 by 88 feet (16.76m x 26.82m). 

Today’s race spans 1 1/4 miles (10 furlongs), but its origins trace back to a 1 1/2-mile event at the iconic Churchill Downs Racetrack in Louisville, Kentucky.

 The game spans 60 minutes, split into two  30-minute periods. Think of it like catching your breath during halftime between those action-packed periods. These periods are made up of Jams, like the building blocks of roller derby action. Each Jam can go on for up to two minutes.
