Paper Cup Sleeve Calculator

A sleeve is a band cut from the same cone as the cup. Enter the cup dimensions and the sleeve height to get the flat blank, the arc length, the paper area and the weight per 1,000 sleeves.

Geometry, not a factory die. Real sleeve dies add a glue tab, a small top/bottom allowance and machine registration. Use this to sanity-check a quote and a board weight, then confirm the die with the factory before artwork.

How a Sleeve Blank Is Built

A sleeve is the same cone as the cup, cut as a band. Unroll the band and you get an annular sector — the same shape as the cup wall blank, but narrower. The radial width is the band's slant height, not the sleeve height: because the cup tapers, a 45 mm vertical sleeve is about 45.4 mm across the flat blank.

The outer radius comes from the full cup cone; the inner radius is the outer radius minus the band width. The arc length at the top equals the cup circumference, πD. Add the glue overlap to the arc, not to the width.

Standard Sleeve Sizes

These are the combinations we see most often. They assume the sleeve sits at the rim and covers the upper part of the cup.

A sleeve that covers the middle of the cup fits a narrower band; a sleeve that sits at the rim needs the full top circumference. Both are calculated from the same cone.

Paper Weight and Insulation

250 gsm is the standard: enough stiffness to hold its shape and enough insulation for a hot cup. 280–300 gsm feels more premium and insulates better, but adds cost and makes the seam harder to fold. Kraft and white board behave differently: kraft is stronger at the same weight but prints darker.

Insulation comes from the air gap and the board, not from a coating. A PE-coated sleeve does not insulate better; it only resists condensation.

Glue Seam and Fit

The seam is the weakest point. 10–15 mm of overlap with a paper-to-paper glue is standard; a wider seam wastes board, a narrower one opens when the sleeve is pushed onto the cup. If the sleeve is applied by machine, the overlap also needs a registration mark.

Test the sleeve on the actual cup, not a sample cup: rim diameter varies by a millimetre between factories, and a sleeve that is tight on one cup can be loose on another.
