What is the difference between sizes and grading? A size is usually based on the chest circumference if it is a sweater. Sizes for babies, with the exception of the 0-3 months to 6 months span, tend to jump up a size every six months. Standard sizes are 3 months, 6 months then it jumps to 12 months, and jumps another 6 to 18 and another 6 to 24.

The grading for sizes is uniform. The information can be found on any knitting or crochet schematic. Grading is the increments you increase a neck width, shoulder width, chest width, sleeve width, sleeve length, armhole depth, length from hem to armhole, total length of garment, waist, and hip from one size to the next size. The increments are usually pretty standard and are given in the schematic.

Read a schematic for a baby outfit and you will see that finished chest sizes for a 6 month old is always 2″ (5) cm larger than the 3 month size. If the sweater is a cardigan 1″ (2.5) cm difference in chest size between the 6 month and 12 month. Between the 12 and 18 month the chest size increases a half inch (1.25) cm. Between the 18 and 24 month size its another half inch (1.25) cm.

Neck widths start at 3 inches (7.5) cm for a 3 month old, increase a half inch (1.25) cm for size 6 months and doesn’t increase again until baby is 24 months when it is another half inch (1.25) cm larger at 4″ (10) cm.

Shoulder widths start at 2 inches (5) cm. The width remains the same for the 6 month size. Then the widths are graded a quarter inch (0.64) cm larger for sizes 12 and 18 months. The 24 month size is the same as the 18 month size 2.5″ (6.5) cm.

The armhole depth is graded in quarter inches (0.64) cm from 3.75″ (9.5) cm to 5″ 12.75) cm for each size.

Body length to underarm is graded 1″ greater (2.5) cm between 3 and 6 months. Then remains steady at a half inch (1.25) cm grade for 6 through 24.

Sleeve length is graded 1″ greater between all sizes.

Body width at shoulder also called the crossback is graded in increments of a half inch (1.25) cm.

Again, all the increments are on the schematic. It is just a matter of subtracting the larger number from the smaller number to see their grading.

Read a lot of schematics and create a grading resource for yourself. Collect enough numbers to make a grading guideline you feel is best for the clothes you are designing.

Finding information on how to grade children’s clothes and adult clothes is done the same way. Research, collect the numbers, find out how they work together and make them your own.
