How Long Are The Sleeves Of A Baby Sweater?

The length of the sleeves of baby sweaters changes as the baby ages, as follows:

For babies aged 0-3 months, the sleeve length is 14cm.
For babies aged 1 year, the sleeve length is 18-19cm.
For babies aged 2 years, the sleeve length is 24cm.
These sizes can adapt to the arm lengths of babies of different ages, ensuring that the sweater is both comfortable and suitable. In addition, the thickness of the thread needs to be considered when knitting a sweater, because threads of different thicknesses require different numbers of needles, which affects the size and tightness of the sweater. For example, when using thick thread, about 120-180 needles are required; when using medium-thick thread, about 140-200 needles are required; when using thin thread, about 180-220 needles are required. This size is basically suitable for children of the above ages, and can be worn for more than a year.
