How Pattern Row Validator Works?

The Pattern Row Validator works by comparing the Needle Stitches you have with the Stitches Consumed by a written row. A valid row uses exactly the stitches on the needle.

  1. Enter the needle count

    Tap in the stitches on your needle.

  2. Add up the row

    Press → once for each stitch the written row uses: k1 uses 1, k2tog uses 2, yo uses 0.

  3. Compare

    The row is valid when Stitches Consumed equals Needle Stitches.

  4. Count stitches made

    Add up stitches made by each move to get the count after the row.

Pattern Row Validator Formula

The Pattern Row Validator formula is stitches consumed = Σ (stitches used by each move), and the row is valid when that sum equals the needle count.

Consumed
C = Σ used

Add the stitches each move uses.

Produced
P = Σ made

Add the stitches each move makes.

Valid row
C = needle stitches

A mismatch means a typo or a wrong size.

Worked example: The row "k2, [yo, k2tog, k4] ×10, k2" uses 2 + 10 × 6 + 2 = 64 stitches and makes 2 + 10 × 6 + 2 = 64 stitches, so it fits a 64-stitch needle with no change.

Pattern Row Validator Conversion Table

The Pattern Row Validator conversion table checks 6 written rows against their needle counts.

[k6, k2tog] ×12968496 ✓
[k4, M1] ×15607560 ✓

A row that does not fit your needle count often means the pattern is for a different size.

What is Pattern Row Validator?

A Pattern Row Validator is a tool that checks a written row uses exactly the stitches on your needle and works out the stitches it produces. Pattern typos happen, and a quick check catches them before you knit.

The validator counts each move once. The Stitches Counter tool saves both totals in your browser.

What are the uses of Pattern Row Validator?

There are 4 main uses of the Pattern Row Validator, including typo checks, size checks and design checks.

  • Typo checks

    Catch pattern errors before knitting.

  • Size checks

    Confirm you are reading your size.

  • Design checks

    Check rows in your own patterns.

  • Lace rows

    Check yo and decrease balance.

About the Pattern Row Validator

Verify mathematical consistency of a written row instruction: confirms stitches consumed match your needle count and calculates stitches produced.

How to Use This Tool Efficiently

  • ✓Catch pattern errata or typos in published books before you begin knitting.
  • ✓Double decreases (CDD) consume 3 stitches and produce 1; yarnovers consume 0 and produce 1.
