Rule and assumptions

Template width = preset circumference + bleed. Template height = preset body height minus top and bottom clearance. Presets are starting points.

  • 20 oz cup shapes are not universal.
  • Measure top diameter, bottom diameter, and height for production templates.

Use this tool for

  • Estimating 20 oz skinny tumbler wrap size.
  • Comparing 20 oz straight and tapered template starting points.
  • Adding bleed or seam overlap to a 20 oz template.
  • Creating a copyable 20 oz tumbler template spec for a test print.

Worked example

Inputs

  • Unit: inches
  • 20 oz type: 20 oz skinny
  • Bleed / seam overlap: 0.25 in

Result

A 20 oz skinny preset returns about 9.60 in starting width and 8.20 in starting height.

When to use this

Use this when the cup is a common 20 oz shape but you still want a measured production check.

What to check before pressing

Verify the exact cup model, printer scaling, seam overlap, and top/bottom clearance before sublimating.

Quick reference chart

Use case Starting point Check before pressing
Skinny Tall narrow wrap Most common 20 oz craft preset
Straight Use measured circumference Less taper correction
Tapered Use custom calculator Top and bottom differ

Common mistakes

  • Treating all 20 oz cups as skinny tumblers.
  • Skipping seam overlap.
  • Using a template without a test print.
