DK Equivalent Yarn Calculator — Yarn Weight Substitution

Yes, but you need to adjust stitch counts, row counts and needle size. The key is to match the fabric density and drape. Knit a tension square with the substitute yarn and compare it to the pattern gauge. The finished garment will use different total yardage.

Multiply the pattern stitch count by the ratio of your gauge to the pattern gauge. For example, if the pattern calls for 100 stitches at 22 sts/10cm and your yarn knits at 18 sts/10cm, you need 100 x 18/22 = 82 stitches to achieve the same width.

No. A heavier yarn creates a thicker, less drapey fabric. A lighter yarn creates a thinner, more fluid fabric. The stitch definition and texture will also differ. Cable patterns look better in smoother, heavier yarns. Lace opens up more in finer yarns.

Heavier yarns use more yarn by weight but fewer metres. Lighter yarns use less weight but more metres. When substituting, always compare total metres (not grams) to determine how many balls you need.
