Held-together yarn has a weight class of its own, and the labels already know it: per meter, the bundle weighs what its strands weigh together. Enter each strand’s label numbers; the combined class comes back with the math shown.
Your Strands
From each label: the skein’s grams and its length. Leave strand 3 empty unless you’re holding three.
Held Together, This Knits As
2 strands · 224 yd per 100 g combined
- Strand 10.250 g/m (437 yd/100 g)
- Strand 20.238 g/m (460 yd/100 g)
- Combined density0.488 g per meter
- Combined224 yd / 100 g → class 4
The Formula
combined grams per meter = strand 1’s + strand 2’s (+ strand 3’s) · combined yd per 100 g = 100 ÷ grams per meter × 1.0936A meter of the held bundle contains a meter of every strand, so the weights per meter simply add. The combined yards-per-100-grams then reads against the same density ranges that class single yarns.
Worked Example
Fingering (100 g / 437 yd) held with lace-weight mohair silk (50 g / 230 yd):
- Fingering: 0.25 g per meter. Mohair: 0.238 g per meter. Together: 0.488 g/m → about 224 yd per 100 g.
- That density reads as light worsted / DK: exactly the class knitters report for this famous combination.
- Swatch anyway: mohair’s halo knits loftier than its grams suggest, so many knitters needle it as DK-to-worsted.
The Quick Rules, Checked by the Math
| Held together | Knits as, roughly |
|---|---|
| 2 × fingering | DK |
| 2 × sport | Worsted |
| 2 × DK | Aran / chunky |
| 2 × worsted | Chunky / super bulky |
| Fingering + lace mohair | DK |
| 3 × fingering | Worsted |
How to Measure Your Inputs
- Both numbers from each label: grams and length. Meters? Multiply by 1.0936 for yards, or let the conversion calculator do it.
- No label: weigh the skein, measure ten yards, weigh those if your scale reads tenths, or wrap for WPI and borrow a same-class label.
- Yardage planning: each strand spends its full length: a 1,000 yd project held double needs 1,000 yd of each strand.
Assumptions and Defaults
- Class boundaries use typical yd/100 g densities; fibers bend them: lofty wool knits lighter than its grams, dense cotton heavier.
- Two strands don’t double the WPI: the bundle rounds, landing near single-strand WPI ÷ 1.4.
- The gauge swatch outranks the class: hold the strands, knit, measure.
