Sleeve increases: how many rows between?
Enter the stitches you have now, the stitches you want at the end and how many rows to work over. The plan tells you how often to increase or decrease.
Usually 2: one at each side.
Increase 2 sts: every 9th row 4 times, then every 8th row 8 times.
Increase 2 sts · 100 rows
| Knitted | Rows between | Times |
|---|---|---|
| 9 | 4 | |
| 8 | 8 |
Each mark is a row; the green ones are the shaping rows.
Make it a counter in KnitBuddy that reminds you on every shaping row, and keep the plan in your project.
How to work it out yourself
Example: a sleeve goes from 52 to 76 stitches over 100 rows, 2 stitches each time.
- The difference is 76 − 52 = 24 stitches. At 2 stitches each time that is 24 ÷ 2 = 12 shaping rows.
- Share the 100 rows out over the 12 shaping rows: 100 ÷ 12 = 8, with 4 rows over.
- Those 4 rows make 4 of the gaps one row longer: 9 rows, and they come first. The other 8 gaps are 8 rows.
- Check: 4 × 9 + 8 × 8 = 100, so the last shaping row is row 100. Written as a pattern:
Increase 2 sts every 9th row 4 times, then every 8th row 8 times
Decreasing down a body works the same way, the other way round: from 80 to 56 stitches over 104 rows is 12 shaping rows, Decrease 2 sts every 9th row 8 times, then every 8th row 4 times.
Questions
- Why 2 stitches each time?
- On a sleeve you usually increase one stitch at each side on the same row, so each shaping row adds 2. Knitting in the round, the two increases sit either side of a marker under the arm.
- What if the numbers don't add up?
- The stitches to add or take away must divide by the stitches each time: going from 52 to 77 cannot be done 2 at a time. You also need at least as many rows as shaping rows; if not, the calculator says there are too few rows and how many you need at least.
- Does it work for rounds as well as rows?
- Yes. Count rounds instead of rows: every 9th round 4 times works just the same on a sleeve knitted in the round.
- Where do I get "Over how many rows" from?
- It is the length you knit the shaping over, turned into rows with your tension: rows per 10 cm times the length in cm, divided by 10. The tension (gauge) calculator on this site does the conversion for you.
