A. NEEDLE SIZES & LENGTH
Knitting needle sizes conversion chart
You can find out what size knitting needles and gauge you will need to achieve with a specific yarn by looking at the product details on a yarn page or by simply looking on the label of a skein of yarn.
Long or short. The type of project determines the length of your needle. Most patterns have suggestions for the length.
Most straight needles are 10-16″ (25-40 cm) long. Circular needles range enormously and can be as short as 22cm (8½in) or as long as 150cm (60in), however the most commonly used lengths are 40, 60 or 80cm (16, 24, or 32in)
If you want to knit blanket or sweater needs a longer needle. Small, flat projects can be worked on any needle length. Small ones like socks need a short circular needle or double-pointed needles.
B. TYPES OF KNITTING NEEDLES
1. Straight Needles
Straight needles come in sets of two needle, and each has a point at one end and a knob or stopper at the other, they are straightforward and easy to use.
2. Double-Pointed Needles

4. Interchangeable Needles
They have a firm tip and a flexible cord. Interchangeable knitting needles have a lot more functionality than fixed circulars, the pieces separate so you can change out the needle sizes and cord lengths. You can also connect needles to cords and attach caps at the ends so you can use them like straight needles.
Having this flexibility is incredibly helpful for most knitting projects
