How the kids' block is drafted
Choose a height and the tool fills in the child's measurements for that height from standard body measurements tables: bust and hip, back waist length and garment length. If the child is slimmer or bigger than their peers, adjust the bust: neck, shoulder width and armhole depth still come from the height. Up to about age 9–10, boys' and girls' figures are nearly the same, so the pattern fits both.
The kids' block differs from the adult one. The neckline is wider by ⅜ in1 cm on each side so the head fits through: a child's head is large relative to the neck. Children's shoulders are wider relative to the bust, so the shoulder slope is smaller, and for little ones it shrinks further in proportion to height. The sleeve cap is low, and the cap itself is ⅝ in1.5 cm shorter than the armhole — the knit fabric eases in when you set in the sleeve; sleeve length and hem width are filled in by height on the "Sleeve" tab.
We checked the draft against proven commercial patterns for the same style: the key measurements match.
Sleeve and hood
Draft the block, then go to the "Sleeve" tab: the tool takes this block's armhole and makes the cap lower for a dropped shoulder. On the "Hood" tab, the hood neckline is taken from this block's neckline.
How to print and tape
Download the PDF on Letter or A4 sheets and print at 100%, without "fit to page". The first sheet has the test square: measure it with a ruler. Sheets are taped together with an overlap along the ⅜ in1 cm strips; sheet numbers and the assembly diagram are on the first page. For a copy shop or plotter, choose "One-sheet PDF".
What you get
Full-size T-shirt front and back on the fold: armhole notches for the sleeve and a notch at the waistline, grainline, seam allowances and hem allowance.
FAQ
How do I sew a long-sleeve tee?
Draft the T-shirt, then on the "Sleeve" tab keep the length the tool filled in — that's a long sleeve to the wrist with a little room to grow. For a short sleeve, set the length to 3⅞–5⅞ in10–15 cm and the hem width to ¾–1⅝ in2–4 cm more than the upper arm.
What if the child is between heights?
Choose the next height up and adjust the bust if you know it. Neck, shoulder and armhole measurements will then come with a little extra room, and you can shorten the garment length by ⅜–¾ in1–2 cm.
