Tumbler Wrap Calculator
Calculate top/bottom wrap widths from diameters for straight or tapered tumblers.
How it works
Top width = π × top diameter.Bottom width = π × bottom diameter.
If they differ, the wrap is a trapezoid.
Worked example
Top 3.1 in / bottom 2.7 in → widths ≈ 9.74 in / 8.48 in at 8.2 in height.Sublimation tips
| Tip | Why |
|---|---|
| Use brand template | Beats hand math for tapered cups |
| Mirror art | Most presses require it |
| Leave seam gap | Prevents overlap wrinkles |
Frequently asked questions
Can I use the mug wrap tool instead?
Only for straight cylinders. Tapered tumblers need this tool or a supplier template.
Why does my logo lean?
Usually a rectangular wrap on a tapered cup. Use the trapezoid template from the blank maker.
Do I mirror the art?
Most mug/tumbler presses need mirrored files — confirm for your press.
What about seams?
Leave a small overlap or safe gap depending on your tape and press method.
