Sizing up needlesA needle’s size is determined by its diameter. The smaller the size, the narrower the needle and the smaller the stitch it makes. The following figure shows needle sizes and their US and metric equivalents.
If you aren’t sure what needle sizes you’ll need in the future, try a circular knitting needle set with interchangeable tips. Even though the needle is designed for circular knitting, you can also use it to knit back and forth. Some sets feature plastic needle tips, some metal. These sets allow you to combine different-sized needle tips with different connector cords to make a very large range of needle sizes on the fly. An interchangeable circular needle is especially handy when you’re unsure which needle size to use for a given yarn. If the current size isn’t giving you the right gauge, simply switch the tip up or down one size instead of starting over on another needle.
Accounting for needle makeup and tip typeKnitting needles, which were first mass-produced in steel, have been made in ivory, tortoiseshell, silver, whale bone, and more. Today you can find them made in ebony and rosewood, sherbet-colored pearly plastic, Teflon-coated aluminum, and even 14-carat gold-plated (no kidding!). And that’s only the beginning. Whatever your needles are made of, the material does contribute more or less to your knitting comfort, speed, and the quality of your stitches. Here are some recommendations:
If you’re new to knitting, you’re working on double-pointed needles, or you’re executing color patterns, good choices include wood (bamboo, walnut, and so on) and plastic. Wood and some plastics have a very slight grip, giving you more control over your work and discouraging dropped stitches.
If you’re knitting in stockinette or a straightforward stitch pattern, a slippery needle makes sense. The fastest ones are nickel-plated brass and call themselves Turbo. Use these needles and watch your stitches fly by before your eyes. (Also watch for more-easily dropped stitches.)
Needle tips can be long and tapered or rounder and blunter (see the figure below). If you’re working a project with a lot of stitch manipulation (as in lace or cables), or if you’re a snug knitter (that is, your stitches are tight rather than loose), you’ll have an easier time if you use a needle with a long, tapered tip. If you’re knitting with a loosely spun yarn and/or you’re a relaxed knitter with looser stitches, you may prefer a blunter point.
Though they don’t fall directly into the category of different needle composition or tip type, square needles can be a great choice if you’re new to knitting. They’re made of metal or wood, and the shape makes them easier for the hands to hold. Stitches don’t fall off these square needles as easily as the standard round ones.
