T-shirt print area size in inches
For sizes S through L, the Shirtready print area is 36 × 50 cm, about 14.2 × 19.7 inches. The designer draws that box on the shirt preview, and your artwork has to sit inside it.
Where the box sits
The box is centered side to side on the shirt. Its top edge starts about 4 cm (1.6 inches) below the collar.
Larger sizes
XL and larger sizes can show a different box. The print-area label above the preview gives the exact size for the shirt and size you picked.
Sizing a design
Measure your artwork in inches at the size you want to print. If it is 14.2 inches or less wide and 19.7 inches or less tall, it fits the S to L box at that size.
