Conversions T-shirt front (adult)

Print providers publish their print areas in inches and want files in pixels. This converts between them and shows whether your design actually fits the placement.

How to read this

Pixels = inches × DPI. That is the whole calculation, and it is the one people get wrong by exporting at a fixed pixel size regardless of how large the design prints.

The diagram draws your design inside the selected print area to scale, so an overflow is visible rather than something you discover after the first order.

Questions

What size should a t-shirt front design be?
Most adult front placements are 12 x 16 in. Youth is nearer 9 x 12 in, and a left chest print is about 3.5 in wide.
Should I fill the whole print area?
No. A design that reaches the edges of the printable area lands very close to the seams on smaller sizes.
