Knitting row calculator

How to use this calculator

1. Measure row gauge after washing and drying the sample as you will finish the project.
2. Enter the target length, then the row repeat. Use 1 for a pattern with no repeat constraint.
3. Add starting and finishing rows only if they are outside the repeat; inspect both suggested lengths.

How do I convert knitting length to rows?

Divide the rows in your swatch by its measured length to get rows per unit. Multiply by your target length. If a pattern has a row repeat, choose a whole number of repeats plus any fixed starting and finishing rows.

The calculation

Ideal rows = length × rows per cm. Valid totals = row repeat × positive whole number + fixed extra rows.

A worked example

70 cm at 28 rows per 10 cm is 196 rows. With an 8-row repeat and no extras, 192 rows gives 68.57 cm; 200 rows gives 71.43 cm. The tie selects 192.

Before you cast on

Confirm whether your pattern counts the cast-on or bind-off as a row. Row gauge must be measured in the same stitch pattern after the same washing and blocking treatment.

Measure a representative, washed and dried swatch without stretching it. See method sources and measurement guidance.

Display values round to 2 decimals; calculations keep full precision. Counts are whole numbers. No calculator can promise fabric behaviour.
