IBO Archery
IBO (International Bowhunting Organization) is one of the major 3D archery organizations in the United States, running national and regional tournaments on bowhunting-themed 3D courses. IBO faces use simple concentric rings — an 11-ring inner spot at the centre of the 10-ring, surrounded by an 8-ring vital area and the body silhouette — making them visually less busy than ASA faces.Details
IBO national events run on standardized animal targets at color-coded stake distances. The Pink stake is 20 yards, Red is 30, and Blue is 50 — each colour corresponds to a class. Bowhunter classes shoot Pink/Red; Open and Pro classes shoot Red/Blue. A round typically covers 20 targets across two days, with arrow scoring on a per-target basis.
Scoring is straightforward: 11 (centre dot, 11 points), 10 (the kill ring, 10), 8 (the vital ring, 8), body (anywhere on the silhouette, 5 points), and miss (off the silhouette, 0). No calling mechanic, no asymmetric zones — the design is meant to mirror real bowhunting shot placement decisions. The 11-ring on McKenzie IBO targets is approximately 25% of the 10-ring diameter (so on a medium target where the 10 is 5 inches, the 11 is around 1.25 inches).
For training, scaled IBO faces reproduce the same ring geometry at a calibrated print scale. The 11/10/8/body cascade also serves as the geometric base for our WA-3D and IFAA practice prints, which reuse the same physical face geometry but apply different scoring rule overlays.

Common questions
- What does the 11-ring mean in IBO scoring?
- The 11-ring is the small inner spot at the dead centre of the 10-ring. Hitting it scores 11 points instead of 10, rewarding centre-mass precision. The 11 is roughly a quarter-inch to one-inch diameter depending on target size — small enough that it's a deliberate aim rather than a free upgrade on every 10.
