Yarn Remaining Work Estimator
Estimate work possible with remaining yarn.
Yarn Remaining Work Estimator: Quick Calculation
How Yarn Remaining Work Estimator Works?
The Yarn Remaining Work Estimator works by weighing your Remaining Yarn (g) and dividing it by the grams one row uses to give the Possible Rows you can still work.
Weigh one row
Weigh the ball before and after a row, or weigh 10 rows and divide by 10.
Weigh what is left
Weigh the remaining yarn and tap the grams into Remaining Yarn (g).
Divide
Divide the remaining grams by grams per row.
Keep a margin
Keep enough for the bind-off and a 6 in (15 cm) tail.
Yarn Remaining Work Estimator Formula
The Yarn Remaining Work Estimator formula is possible rows = remaining grams ÷ grams per row. The bind-off needs about 3 times one row's yarn.
- Possible rows
R = g ÷ rg is Remaining Yarn and r is grams per row.
- Bind-off reserve
Reserve ≈ 3 × rHold this back for the bind-off.
- Safe rows
Safe = (g − 3r) ÷ rWork no more than this before binding off.
Worked example: Thirty-eight grams left at 2.5 g per row allows 38 ÷ 2.5 = 15 rows. Keeping 7.5 g for the bind-off leaves 12 safe rows.
Yarn Remaining Work Estimator Conversion Table
The Yarn Remaining Work Estimator conversion table gives safe rows for 6 remaining weights at 4 grams-per-row values.
| Remaining | 1 g/row | 2 g/row | 3 g/row | 5 g/row |
|---|---|---|---|---|
| 10 g (0.35 oz) | 7 | 2 | 0 | 0 |
| 20 g (0.71 oz) | 17 | 7 | 3 | 1 |
| 30 g (1.06 oz) | 27 | 12 | 7 | 3 |
| 50 g (1.76 oz) | 47 | 22 | 13 | 7 |
| 75 g (2.65 oz) | 72 | 34 | 22 | 12 |
| 100 g (3.53 oz) | 97 | 47 | 30 | 17 |
Rows get longer on shawls that increase, so weigh a recent row.
What is Yarn Remaining Work Estimator?
A Yarn Remaining Work Estimator is a tool that predicts how many more rows the yarn you have left will make. The race between the last rows and the last of the yarn is called yarn chicken.
Weighing turns yarn chicken into a plan. The Stitches Counter tool saves the remaining weight and row figures in your browser.
What are the uses of Yarn Remaining Work Estimator?
There are 4 main uses of the Yarn Remaining Work Estimator, including shawl edges, last skeins and stash projects.
Shawl edges
Decide when to start the border.
Last skeins
Stretch the last skein of a sweater.
Stash projects
Plan rows from leftovers.
Stripes
Plan stripe heights from small balls.
About the Yarn Remaining Work Estimator
Weigh your remaining yarn cake to calculate how many more rows you can safely knit before losing at yarn chicken.
How to Use This Tool Efficiently
- ✓Never lose yarn chicken again! Know whether you have enough yarn to start another row.
- ✓Weigh your yarn cake before and after working 1 full row to determine yarn per row.
