Rule and assumptions

Hoodie usable width = size preset x placement factor x style adjustment. Zip-up and pocket areas reduce usable width. Adjustments are starting points.

  • Kangaroo pockets and zippers should be measured before pressing.
  • Back prints may conflict with hood position.

Use this tool for

  • Sizing hoodie front decals around kangaroo pockets.
  • Reducing a zip-up hoodie design so it does not bridge the zipper.
  • Checking sweatshirt decal size against thicker seams.
  • Planning a back hoodie print that will not be hidden by the hood.

Worked example

Inputs

  • Unit: inches
  • Hoodie size: Adult M
  • Hoodie style: pullover
  • Placement: center front
  • Design aspect ratio: 1.25

Result

The front decal starts around 8.64 in wide by 6.91 in high after the pullover and pocket-area adjustment.

When to use this

Use this when a T-shirt decal chart feels too large for a hoodie front.

What to check before pressing

Check the kangaroo pocket top edge, zipper path, hood overlap, and press pressure before production.

Quick reference chart

Use case Starting point Check before pressing
Pullover front 8 to 10.5 in wide Avoid kangaroo pocket
Zip-up front Split or reduce width Do not bridge the zipper
Back hoodie 10 to 12 in wide Check hood coverage

Common mistakes

  • Using a T-shirt chart on a zip-up hoodie.
  • Placing too low over a kangaroo pocket.
  • Forgetting the hood can cover upper-back prints.
