# Raddle Calculator

### What It Does

If using a raddle where the spacing doesn't directly correspond with the ends per inch (such has spacing per inch) or ends per centimeter (spacing of a centimeter), this calculator assists with how to spread the threads so that the width of the warp after spreading is equal to the planned width in the reed.

Two commonly used raddles are the Louet (.5cm per dent, or 2 dents per centimeter) and the Lofty Fiber (4 spaces per inch).  Preset patterns are available for these raddles.

If not using one of the above raddles, enter the reed dents per inch/cm and enter a pattern to calculate the effective sett.
