With all the choices of knitting needles sizes, how do you know the size Metric, US or Canadian to go with? Each pattern you use and each gauge you need to come up with comes from different yarns and needles.
The knitting needle or knitting pin is a long stick or rod, used to make knitted articles. The needle is what is used to snag the yarn through the stitch. The simplest design of the knitting needle is smooth, and long enough to reach through the stitch.
Knitting needles come in all shapes and sizes. They also usually come in pairs. The oldest known knitting needles, still very much in use, are double-pointed needles.
Straight needles are narrowed nearly to a point at one end and capped at the other with a knob or head (like the head of a straight pin), and are used almost exclusively for knitting flat two-dimensional fabrics like rectangles and squares.
They are generally used to form tubular fabrics such as socks and the bodies or sleeves of sweaters. As the name implies, double-pointed needles are tapered at both ends nearly to points. They are normally used in sets of four or five.
Typical 21st century double-pointed needles range from about 4 to 15 inches in length. Shorter needles are used for knitting socks and the fingers of gloves. Longer needles are used for nearly all other work, including sweaters, shawls and blankets.
Both tubular and flat knitting is also done on circular needles, today consisting of two pointed needles joined together by a flexible wire or length of nylon. Some manufacturers sell the two needles and the joining length of nylon separately.
Knitting needles are often selected for color. This color should be different from the color you are choosing to knit with, length, size and number. Choosing the right needle will be detrimentatl to the success of your knittting project.
To no surprise the needles differ in manufacturers that are supposed to use the same size, though they may have different diameters. If you have to change a needle in the middle of your project, compare the actual diameter.
Single point needles size from the range 0000 to 50, the smaller of the numbers represent the thinner of the needles.
Double-pointed needles aremade in even inch lengths of “5, 6”, 7” 10” and 14”. The size of double-pointed needles varies with the material from which the needles are made. Plastic needles range from 1-10 from fine to thick. In contrast the steel double-pointed needles are made from 18-8 with the highest number being the thinnest needle. For aluminum needles it can go either way.
Circular needles consist of two flexable needles that are connected with a flexable cord.
The solid needles are made of bamboo, wood or metal. The sizes are the same way single point are. The smalllest sizes 0-3 are usually made of steel. The other part to the circular needles that are unique because you add in the length. This would typically be 29”, 16”, 20” 24” and 32” are also made. A commonly used size would be “15 by 29”.
