How Rows for Length Calculator Works?

The Rows for Length Calculator works by multiplying your Desired Length (in) by your row gauge to give the Required Rows. Type the rows in your 4 in (10 cm) swatch and the length into the calculator panel.

  1. Measure row gauge

    Count rows over 4 in (10 cm) on a washed swatch.

  2. Enter the rows

    Type the swatch row count into the first box.

  3. Enter the length

    Type the length you want in inches into the second box.

  4. Count the rows

    Use the main counter to count rows up to the result.

Rows for Length Calculator Formula

The Rows for Length Calculator formula is rows = desired length × rows per inch. Subtract rows already worked to get the rows left.

Rows
R = L × r

L is the length in inches and r is rows per inch.

Rows left
Left = R − worked

Worked is the rows already done.

Length from rows
L = R ÷ r

Use the reverse to check a length.

Worked example: A sleeve of 18 in (45.7 cm) at 6 rows per inch needs 18 × 6 = 108 rows.

What is Rows for Length Calculator?
