Main width measurements
Chest controls upper width; hips or hem width control the lower opening. Ease can be positive or reduced for stretchy knit fabric.
Sewing pattern guide
T-shirt measurements guide
A T-shirt draft depends on body measurements and knit fabric behavior. Neckline, armhole, sleeve, and neckband compatibility are especially important.
Body length
Shirt length changes where the hem sits and how much room is needed at the hips.
Shoulder and armhole
Shoulder width positions the armhole. The armhole curve should be smooth and compatible with the sleeve.
Sleeve length and cap
The sleeve cap must match the T-shirt armhole, and sleeve length must match the chosen style.
Round or V neckline
A round neckline should curve smoothly; a V neckline should meet at a clean point and still connect clearly to the shoulder.
Neckband length
The neckband is usually shorter than the neckline on knit fabric, but the exact amount depends on stretch and recovery.
Before cutting fabric
After generating a T-shirt, check front/back shoulder seams, armhole and sleeve cap match, neckline shape, neckband length, stretch direction, hem allowance, and fabric recovery.
