Liutalab

Liutalab is the essential tool for luthiers who want to understand the mechanics of their instrument and avoid costly mistakes.

The secret to a powerful, resonant guitar lies in the correct flexural rigidity of the soundboard. Liutalab lets you calculate it precisely — no more guesswork.

WHAT YOU CAN DO

Calculate the ideal thickness of the soundboard based on string tension and wood properties.

Design brace dimensions for any bracing pattern: X-bracing, Fan, Falcate, or Lattice.

Verify the actual rigidity of your soundboard before gluing it to the ribs, using the built-in deflection-based stiffness check.

MATERIALS DATABASE

Choose from the most common tonewoods — Spruce, Cedar, Sitka, Balsa — or enter your own measured Elastic Modulus for maximum accuracy.

TARGET REFERENCE VALUES

Liutalab provides benchmark flexural rigidity values for different instruments:
· Classical guitar
· Acoustic guitar
- Ukulele

SAFE EXPERIMENTATION

Design and test new bracing patterns and immediately see how they affect the structural behaviour of the soundboard before committing to a build.

Liutalab is built for professional luthiers, students of lutherie, and anyone who wants to go beyond intuition and truly understand their instrument.
