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.
