DPI
Mug wraps are sized from circumference (π × diameter) minus handle gaps on some blanks. Enter diameter, wrap height and top/bottom clearances to get art size and a 300 DPI canvas.

Tapered travel mugs need brand-specific trapezoid templates — this tool is for cylindrical mugs.

How it works

Wrap width = π × diameter.
Art height = available height − top clearance − bottom clearance.
Pixels = inches × DPI.

Worked example

3.35 in diameter → width ≈ 10.52 in.
With 3.75 in height and 0.25 in clearances → art height 3.25 in.
At 300 DPI ≈ 3156 × 975 px.

Sublimation tips

Tip Why
Leave handle gap if needed Full 360° wraps can wrinkle at the seam
Use poly-coated mugs Standard ceramic needs coating for dye-sub
Mirror the art Most mug presses require mirrored prints

Frequently asked questions

Will this work for tumblers?

Straight tumblers yes if cylindrical. Tapered tumblers need a trapezoid template from the blank maker.

Are Mug Wrap Size Calculator results exact for production?

Treat them as planning estimates. Calibrate against your equipment, invoices and waste logs before you lock customer quotes.

Do my inputs leave my browser?

No. PressMath calculators run client-side. Only the contact form sends data you intentionally submit.

What should I do after I get a number?
