Sample the combined fabric and budget the full working length for each continuous strand.
Before you start
Gather the measurements, counts or timing sample needed below. Record their units and whether they describe a sample, the whole project or one purchased package. Use a finished sample when dimensions or material use depend on fabric structure.
How to do it
- Budget two different yarns held together — For 400 m of working length with one strand of each yarn and 10% reserve, yarn A and yarn B each need 440 m. Their lengths cannot be pooled.
- Make a representative finished swatch — Use the project’s stitch pattern, working direction and finishing treatment. A smooth flat sample does not represent a textured circular garment.
- Gauge is a fabric measurement, not a needle promise — Understand why the same needle and yarn can produce different dimensions, and how a representative, finished swatch turns a chart into a reliable size.
- Interpret care information — Read temperature, agitation, drying and pressing instructions separately. The finished piece must accommodate its most treatment-sensitive component.
Try this example
A sampled scarf requires 400 m of the held pair. Before reserve, yarn A in 100 m balls needs four and yarn B in 200 m balls needs two; the pair does not halve either strand’s required length.
Check your result
- Recheck the inputs against the actual sample or label, keep units consistent and round only the final count or purchase. Repeat a sample if a small measuring difference changes the decision.
- These arithmetic examples assume the measured structure stays comparable. Shaping, borders, dense textures and color changes require their own allowances or samples.

Held-together yarn planner
Plan label-based quantities for one or two yarns held together. Enter the working length needed by each strand, not an already combined total.
Before you use this tool
Enter the working length needed by one strand, not the combined length of every strand. Select how many strands of A and B run throughout.
Each strand consumes the full working length; B can be zero. This estimates separate packages, not the combined yarn weight category or gauge.
Method and limits
Formula and assumptions
Each working strand needs the entered length plus allowance. For each yarn, multiply that length by its strand count, divide by label length, and round up to whole balls. Total purchased mass is the sum of each ball count × label mass. It assumes all strands run together throughout; estimate separate sections separately.
Worked example
Example: 400 m per strand with 10% extra needs 440 m of A and 440 m of B. At 100 m / 50 g for A and 200 m / 25 g for B, plan 5 balls of A and 3 of B: 325 g purchased.
Limits and rounding
Results are planning estimates from the values entered. Displayed decimals are rounded for craft use; whole materials and repeats round up where the method says so. Confirm gauge, material behavior, construction, and finished measurements before committing supplies.
