Row Gauge Adjuster
This handy spreadsheet will help you make adjustments to the number of rows needed for your top down armhole. To use it, you'll need Microsoft Excel, Apple Numbers, or a similar spreadsheet application. To use it, just enter the pattern's stated row gauge, your gauge (measured from your swatch), and the armhole depth for your size that's shown on the pattern's schematic. That's it—the spreadheet will calculate how many rows more or less you should work to maintain the armhole depth. Works with both imperial (inch) and metric measurements.
