Why there is no fixed XS–5XL rule
A size label does not define the printable area. Two medium shirts can have different widths, necklines and cuts. An oversized tee can suit a larger graphic, while a fitted tee may look better with a smaller print.
Use the actual garment dimensions instead of automatically increasing the print for each shirt size.
Measure the visible artwork
Check the artwork’s outermost printed edges. Empty transparent margins can make a file look larger than the design that will actually appear on the shirt.
Confirm how your ordering tool measures the file and review the final width and height before checkout. Keep the original proportions.
Make placement work with the neckline
A crewneck, V-neck and scoop neck create different spaces above the design. Start with a visual centerline, then adjust the design until it looks balanced on the wearer.
Placement distances in this guide refer to the top of the printed artwork, not the carrier film. Chest logos sit on the wearer’s left, which appears on your right when facing the shirt.
Hoodies, pockets and seams
Check the clear area between the neckline and pouch pocket on a hoodie. A hood can cover the upper back design. Zippers, thick seams and raised pockets also affect where a transfer can be pressed evenly.
Measure both the garment and the usable platen area. Do not treat a suggested print area as a guarantee that every garment or press can accommodate it.
One design across several garment sizes
You may prefer one consistent logo size across a group, or smaller and larger versions for different garments. Neither approach is mandatory.
Try a paper mockup on the smallest and largest garments first. If the same print looks too large on one or too small on another, prepare separate sizes.
Large prints change the feel
A large solid graphic covers more fabric than an open, airy design. Think about the visual weight and how the wearer wants the garment to feel.
Photographs and mockups help compare styles, but they are not proof of an exact fit. Your real-size paper test and preferred look should guide the final choice.
