Jump Line Distance Calculator

How line distances work

US hunter and equitation courses are designed on a 12-foot canter stride. A line between two jumps budgets 6 feet for the landing arc of the first jump and 6 feet for the takeoff of the second, with 12 feet per stride in between — so a line measures 12 × (strides + 1) feet. That is why 60 feet is the canonical 4-stride line: 6 to land, four 12-foot strides, 6 to take off.

Riders read courses by walking them in 3-foot steps, four steps to a stride. Two steps off the first jump for landing, then count by fours, then two steps of takeoff at the far jump. The calculator is the same arithmetic without the boots: type the measured distance and it returns the stride count, or pick a stride count and it returns the distance the line should tape.

Change the stride setting and every number recalculates: pony divisions commonly walk on a 10 to 11-foot step, and jumper distances posted in meters convert directly. When a distance lands between clean multiples, the calculator shows both adjacent options and their true measurements — the standard way in-between distances are described on a course walk.

Line distance questions, answered

Why is a stride counted as 12 feet?

Twelve feet is the standardized canter stride that US course designers build hunter and equitation courses around, with 6 feet allowed for landing after the first jump and 6 feet for takeoff at the second. It is a design convention, not a biological constant — actual horses canter shorter or longer — but because everyone designs to it, walking and calculating lines on a 12-foot step is how riders read a course.

How do riders walk a line to count strides?

The traditional method uses 3-foot human steps: four steps to a stride. Walking a line, a rider takes two steps away from the first jump for the landing, then counts every four steps as one stride until reaching the second jump, with the final two steps as takeoff. A 60-foot line walks as 20 steps: 2 for landing, 16 as four strides, 2 for takeoff — which is exactly what this calculator computes.

What does it mean when a line rides long or short?

A line set slightly beyond the clean multiple — say 62 feet where 4 strides wants 60 — is described as riding long in 4 or steady in 5, and one set under the multiple rides short. Course designers use these in-between distances deliberately at higher levels. This calculator shows both whole-stride options with their true distances; how a particular horse should ride it is a question for the rider's trainer, not a calculator.

How do distances change for ponies?

Pony divisions are set on a shorter step — commonly around 10 to 11 feet rather than 12, varying with pony size and the governing rules for the class. The stride-length setting recalculates every distance on whatever step you enter, so the same 4-stride line that wants 60 feet for horses wants 55 feet on an 11-foot pony step.

What does it mean to add a stride?

Adding means fitting one more, shorter stride into the same measured line — riding a 60-foot line in 5 strides instead of the 4 it was set for — and leaving one out means the opposite. The phrase describes a counting choice relative to the designed distance. The calculator shows what the adjacent stride counts measure; whether adding or leaving out is the right call for a given horse and class is riding advice, which we deliberately don't give.
