Paper tuning: What distance?

Paper tuning is simple in theory: shoot an arrow through paper and use the tear to infer how squarely the arrow is leaving the bow. The tricky part is distance. Too close, and the arrow may not have fully revealed the launch error. Too far, and the arrow may already be recovering.

The practical question is: for an out-of-tune launch, where is the arrow yawing the most? That is the distance where paper should be most sensitive to tune error.

We used the 2026 front-of-center slow-motion yaw fits for the torqued shots. The torque condition deliberately injected launch error, which makes it a useful proxy for an out-of-tune or inconsistent launch.

Each build was fit with a damped sinusoid. For this article, we subtract the fitted centerline offset and look for the maximum oscillation magnitude. That avoids treating a camera or model offset as tuning error and focuses on the yaw motion itself.

Across all 11 torqued builds, the fitted yaw motion peaked between 10.0-14.5 ft. The median peak was around 12.0 ft.

The exact peak moved a little by build, but the range was tight enough to be useful. It lands right in the common paper-tuning neighborhood: not directly off the rest, and not so far downrange that the arrow has already started to clean itself up.

Based on this test, paper tuning should be conducted around 10-15 ft from the shooter if the goal is to make launch yaw as visible as possible.

A few caveats:

• This was one bow setup, not a universal proof across every compound platform.
• It did include multiple arrow builds, so the estimate is not tied to a single arrow configuration.
• The result uses fitted slow-motion yaw data, not direct paper tears. It tells us where yaw error should be most visible, not that every paper setup must use the same distance.
