How this calculation works
A target measurement can imply a fractional or incompatible stitch count. This calculator rounds upward to the next count that fits the entered repeat plus edges, then converts the count back to centimetres. You can see the size consequence instead of receiving an unexplained integer.
Stitches = next repeat-compatible count at or above width × stitch gauge; rows = ceiling(height × row gauge)A worked example
20 stitches and 30 rows per 10 cm need 100 raw stitches for 50 cm. A 4n + 2 repeat rounds this to 102 stitches, or 51 cm, with 180 rows for 60 cm.
Good to know
Use the project stitch, yarn and tools, and measure an interior section after the care process you intend for the finished piece. A loose cast-on edge is not a representative gauge measurement. This rectangular plan does not automatically grade a garment, distribute shaping or prescribe another needle size.

The repeat can change the finished width
A target measurement can imply a fractional or incompatible stitch count.
This calculator rounds upward to the next count that fits the entered repeat plus edges, then converts the count back to centimetres. You can see the size consequence instead of receiving an unexplained integer.
The Evenly spaced stitch increase and decrease calculator turns an established starting count into an ordered shaping row. Check gauge first, then decide how many operations the pattern actually requires.
Measure the fabric you will actually use
Use the project stitch, yarn and tools, and measure an interior section after the care process you intend for the finished piece.
A loose cast-on edge is not a representative gauge measurement. This rectangular plan does not automatically grade a garment, distribute shaping or prescribe another needle size.
Change stitch gauge without changing row gauge
Increase the measured stitches across the same swatch width while keeping the row measurement unchanged. More stitches are needed for the target width, but the target row count is unchanged. The two directions are independent observations rather than one interchangeable density number.
When the repeat is four stitches plus two edges, the permitted totals are two, six, ten and so on. An exact target of one hundred stitches therefore rounds to one hundred and two. The resulting extra centimetre in the worked example is a visible design choice, not a rounding error to hide.
Work through the entered example
20 stitches and 30 rows per 10 cm need 100 raw stitches for 50 cm. A 4n + 2 repeat rounds this to 102 stitches, or 51 cm, with 180 rows for 60 cm.
Start with this case, then change one input and calculate again. Keep the other assumptions fixed so the result has an interpretable cause. The result table exposes intermediate quantities and units rather than hiding them behind a single headline number.
Use the output in a real plan
Use the project stitch, yarn and tools, and measure an interior section after the care process you intend for the finished piece. A loose cast-on edge is not a representative gauge measurement. This rectangular plan does not automatically grade a garment, distribute shaping or prescribe another needle size.
Before purchasing material or comparing alternatives, check the measurements at the point where they enter the calculation. A mathematically precise answer can still be a poor plan when the measured size, loss allowance or price basis is wrong. Save the input assumptions with any result you intend to reuse.
A few questions, answered
What is the calculation method?
Stitches = next repeat-compatible count at or above width × stitch gauge; rows = ceiling(height × row gauge)
Does this use live prices or automatic measurements?
No. All measurements, prices and allowances come from your entries. The example values are illustrative and are not a recommendation for your situation.
Can I reuse the result for a different case?
Change the inputs and calculate again. Read the stated units and limits; the assumptions must still apply to the new case.
