Please note, terms like “Bulky” and “Chunky” are terms for gauge and do not mean that the yarn is heavy or cumbersome!
Needle size is determined by both YOUR gauge and the type of yarn that you have selected. If you knit or crochet a yarn too tightly, the hand (or feel) will be hard and the garment will be stiff. If you knit or crochet the yarn too loosely, the hand will be too soft and the garment will be limp. As a starting point, the following needles might give you the desired gauge. However, if you produce a tight stitch, you may need to increase the needle size by 1 or 2 sizes and if your work is loose, you may need to reduce the needle size by 1 or 2 sizes.
| Polar weight: | Knitting needle sizes 15 – 17 or N crochet hook and up |
| Bulky weight: | Knitting needle sizes 10 – 13 or J – M crochet hook |
| Chunky weight: | Knitting needle sizes 9 – 10 or I – J crochet hook |
| Aran weight: | Knitting needle sizes 8 – 9 or H – I crochet hook |
| Worsted weight: | Knitting needle sizes 7 – 8 or G – H crochet hook |
| Sport weight: | Knitting needle sizes 5 – 7 or F – G crochet hook |
Again, these are simply suggestions and are intended to point you in the ballpark of what needle size may produce a specific gauge. PLEASE TAKE THE FEW MINUTES TO KNIT OR CROCHET A GAUGE SWATCH. This will help to insure greater success.
Once you gotten this information (and you've written it down in a safe place!), you might want to use the following free tool: The Knitting Companion. (This link will enable you to download The Knitting Companion.)
To quote the developer, "This program converts a knitting pattern stitch gauge (such as you would find in a knitting magazine) to your knitted swatch gauge. After your swatch gauge information is entered; it can calculate the number of stitches and rows you need to knit for a given number of inches. This permits you to take measurements for a garment, do a swatch, and convert the measurements to stitches and rows."
This certainly takes a little time (and I mean just a little time!). It should take you no longer than an hour or so and this is certainly less time than it would take to rip out a garment. It certainly will take less time than the hours of complaining (Am I the only one who does this ?) about the reasons that your project did not fit!
