What is a Yarn Combination and Guages Chart?

When you knit from a pattern, it will tell you the gauge (also called tension) the designer used—usually written as the number of stitches and rows over a 10 cm / 4" square.

This gauge is important because it helps ensure your finished item ends up the right size.
The chart from Knitting for Olive shows you which yarn combinations and needle sizes typically produce specific gauges.

In other words, it helps you answer the question:

“What yarn thickness and needle size should I use if I need to reach this gauge?”

Here’s how to think about it:

Each row in the chart lists different yarn combinations (for example, a single strand of Merino, or Merino + Soft Silk Mohair).

Each combination tends to produce a certain gauge range, depending on the needle size you choose.

By finding your pattern’s gauge in the chart, you can see which yarns and needles are likely to get you close.

You still need to knit a swatch to check, but the chart gives you a reliable starting point so you don’t have to guess.

Common Questions about yarn combinations and gauges

A yarn combinations and gauges chart shows you which Knitting for Olive yarns — used alone or held together — will produce specific stitch and row counts over a 10 cm × 10 cm swatch. When you're working from a pattern, the designer specifies a target gauge; this chart helps you identify the right yarn combination and needle size to match it, giving you a reliable starting point before you cast on.

Yes — yarn substitution is one of the most practical uses for this chart. Because multiple yarn combinations can produce the same gauge, you can find your pattern's target stitch count and see all the pairings that should get you there. For example, both a single strand of Merino and two strands of Compatible Cashmere reach 28 sts / 38 rows on 3 mm needles, giving you flexibility depending on the look and feel you want.

Always. The chart gives you an excellent starting point based on typical results, but individual knitting tension varies from person to person. Even with the recommended yarn and needle size, your swatch may come out slightly tighter or looser — so it's always worth knitting a 15 cm square, measuring carefully, and adjusting your needle size up or down before committing to a full project.
