Falconry & Raptor Calculator

Professional equipment fitting, fitness metrics, and hood sizers.

Load Preset:

Hood Dimensioning

Beak Width at Gape19 mm
4.0 mm35.0 mm
Cranial/Head Circumference124 mm
30 mm220 mm

Estimated Hood Pattern Sizes

Estimated Dutch SizeSize 20.7Based on head radius
Estimated Indian SizeSize 9.9Based on beak gape ratio

Hood Clearance & Block Ratios

Brace Beak Opening21.8 mm
Approx Block Circumference39 mm (Diameter)
Pattern RecommendationWide Head Ratio: Highly recommend standard Dutch-style hood blocks for ample eye-clearance.

A properly fitted hood must never contact the raptor’s sensitive cornea/eye area, and should seal completely over the beak opening without interfering with respiration.
