## What is Wood Movement Calculator?

Wood Movement Calculator helps woodworkers, joiners, and furniture 
makers predict how much a timber board will expand or contract as 
moisture content changes.

Enter your board width, choose your timber species and grain 
orientation, and set your moisture content range. The app instantly 
calculates the expected movement and flags whether it's low, moderate, 
or high risk for your project.

FEATURES
• 40+ timber species with real shrinkage coefficients
• Flat, rift, and quartersawn grain orientations
• Inches and millimetres
• Climate region presets for seasonal EMC ranges
• Visual board diagram showing direction of movement

PRO UPGRADE
• Save calculations by project name
• Share results with clients and colleagues
• Review your full calculation history

A one-time purchase — no subscription.
