Try the starting example
- Starting stitches
- 100
- Required increases
- 20
- Available rows
- 10
- Final stitches
- 120
- Change count by row
- 2, 2, 2, 2, 2, 2, 2, 2, 2, 2
- Rows with changes
- 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Try another scenario
- Starting stitches
- 20
- Required increases
- 3
- Available rows
- 5
- Final stitches
- 23
- Change count by row
- 0, 1, 0, 1, 1
- Rows with changes
- 2, 4, 5
Calculation method
Calculation method
Final stitches
Starting stitches plus the total required changes.
Change count by row
Row j receives floor(j × changes/rows) minus floor((j−1) × changes/rows), with rows numbered from 1.
Rows with changes
List the one-based row numbers whose allocated change count is positive.
Symbols and units
- a
- Starting stitches
- b
- Required increases
- c
- Available rows
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Distributes a chosen total across whole rows; it does not choose stitch positions, a garment pattern or a stitch technique. Multiple changes can be assigned to a row. Check that your pattern can accommodate them.
