Page guide

Make a row plan that distributes M1 increases evenly while preserving the original stitches at each edge.

How to use Knitting increase calculator
  1. Enter the measured inputs and select their units.
  2. Review the calculated dimensions, counts and rounding.
  3. Download the result and verify it against a sample before making the full project.

Use the right increase operation

This plan uses M1 between existing stitches. Each increase adds one stitch without consuming an original stitch. It is not a kfb plan. Enter the starting count, desired final count and any stitches to preserve on each edge.

Work the original row once

Increasing 12 stitches to 15 gives: work three, M1; work three, M1; work three, M1; work three. Less regular counts produce near-even spacing. Download every step and its position among the original stitches.

Save the calculation

Download a CSV of the results or instructions, a readable text report and a JSON report with values, formulas and assumptions. Calculations run locally on your device. Unit changes keep the numbers already entered, so check the selected units before using the result.
