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.
