Rule and assumptions

Preset width uses a common starting circumference plus bleed. Custom cups should use pi x measured average diameter.

  • Brand and model variation can make presets wrong.
  • Tapered cups need measured top and bottom values.

Use this tool for

  • Finding a starting sublimation tumbler wrap size from a preset.
  • Comparing straight, skinny, tapered, and handled tumbler wrap needs.
  • Adding bleed or seam overlap before printing a test wrap.
  • Moving from a preset chart into a custom tumbler calculator.

Worked example

Inputs

  • Unit: inches
  • Tumbler preset: 20 oz skinny
  • Bleed / overlap: 0.25 in

Result

The preset returns a starting wrap size around 9.60 in wide by 8.20 in high.

When to use this

Use this when you need a fast starting point before measuring a common cup shape.

What to check before pressing

Measure the actual cup circumference and height, then print a paper wrap to check seam alignment.

Quick reference chart

Use case Starting point Check before pressing
20 oz skinny Use as starting preset Measure actual cup
20 oz straight Less taper risk Still check height
40 oz handled Use split zones Handle cutout required

Common mistakes

  • Using a preset without measuring the cup.
  • Forgetting seam overlap.
  • Ignoring handle or taper on larger tumblers.
