Rule and assumptions

Sublimation design width = garment usable width x method factor. Height = width / ratio. Method factors are starting points.

  • This does not estimate blank garment measurements.
  • Polyester content and press setup affect final results.

Use this tool for

  • Planning sublimation shirt placement by method and shirt size.
  • Checking a sheet transfer size against the garment print area.
  • Scaling small sublimation logos without using a full shirt size chart.
  • Preparing a printable placement note for polyester blanks.

Worked example

Inputs

  • Unit: inches
  • Shirt size: Adult M
  • Sublimation method: sheet transfer
  • Design aspect ratio: 1.25

Result

The sheet-transfer starting point is about 8.40 in wide by 6.72 in high for an Adult M shirt.

When to use this

Use this when the question is design placement, not the blank garment size itself.

What to check before pressing

Confirm polyester content, paper size, bleed, and press marks before running the final transfer.

Common mistakes

  • Confusing shirt size charts with design placement charts.
  • Skipping bleed or paper limits.
  • Ignoring fabric content and press marks.
