Size sublimation wraps for straight and tapered tumblers from top/bottom diameters and height. Rectangle files on tapered blanks are a classic skewed-logo mistake.
Straight versus tapered tumbler wrap template shapes.

How it works / formula

Calculation steps

  1. Top width = π × top diameter.
  2. Bottom width = π × bottom diameter.
  3. If they differ, the wrap is a trapezoid.

Worked example

Example (illustrative)

  • Top 3.1 in / bottom 2.7 in → widths ≈ 9.74 in / 8.48 in at 8.2 in height.

Assumptions & limitations

This calculator provides an estimate for planning and quoting. Actual results vary with supplier pricing, ink coverage, waste, labour rates, equipment and marketplace fee changes. Always verify critical numbers before production. See the disclaimer.

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.
