The Golden Ratio Caliper is a precision measuring instrument designed to help artists apply classical proportion with accuracy and consistency.
Based on the mathematical principle of the golden ratio (1:1.618), this tool allows artists to compare relationships between forms, refine compositions, and ensure proportional harmony in drawing, painting, and sculpture.
Purpose
Developed as a practical studio instrument, the caliper supports:
• Proportional measurement
• Comparing sculptural details from reference
• Scaling compositions
• Verifying anatomical relationships
• Applying golden ratio principles in artwork
It is suitable for artists at all levels — from foundational training to advanced studio practice.
Construction & Specifications
Pre-constructed and ready for immediate use.
Maximum measuring length: approximately 35 cm
Available in multiple color options.
Lightweight yet durable, the caliper is designed for repeated studio handling and practical application.
Studio Use
Ideal for:
• Figure drawing and portrait work
• Sculptural refinement
• Composition layout
• Classical atelier training
• Independent study
The Golden Ratio Caliper provides a physical method for understanding proportional relationships — transforming theory into measurable structure.
