Understanding Differences Between US and Metric Sizes
- US Sizes: These are typically whole or half numbers, with smaller numbers indicating finer needles.
- Metric Sizes (mm): Measured in millimeters, metric sizes specify the diameter of the needle. Since metric sizes are based on actual measurements, they provide a more precise standard for needle thickness.
Tips for Converting Knitting Needle Sizes
-
Check Your Pattern’s Gauge: Different designers may prefer specific gauges or knitting tensions, even if the size of the needle seems slightly off. Always knit a swatch to confirm that the needle size you’re using will produce the correct gauge.
-
Experiment with Slight Variations: If you don’t have the exact needle size called for, it’s often okay to go up or down by 0.25 mm. This can give you a similar result, particularly for small adjustments.
-
Invest in a Needle Sizer: A needle sizer tool can help you confirm your needle sizes, especially if your needles aren’t clearly labeled.
-
When in Doubt, Go Metric: Since metric sizes are based on precise measurements, they can be easier to match universally.
