DIY Kiln Drying Schedule Calculator
Use this calculator to generate a custom drying schedule. Enter a few simple details about your wood and kiln. This tool returns a practical drying plan with phase-by-phase temperature, humidity, and time ranges for a small dehumidification kiln.
Wood & Kiln Information
Best results come from 4 inputs:
wood species, whether the wood is green or already air dried, starting moisture content, and board thickness.
wood species, whether the wood is green or already air dried, starting moisture content, and board thickness.
Choose the closest match. If you are unsure, use “Other / Unknown.”
This changes how gentle the early phases need to be.
Example: air-dried hardwood is often around 15–25%.
For indoor furniture, 6–8% is common.
Thicker boards dry slower and need a longer schedule.
A fuller kiln takes longer because there is more wood mass to dry.
Used to estimate how hard the kiln can pull moisture.
