Packing Tape Roll Size Chart: Widths, Lengths, Mil and Boxes Per Roll
A packing tape roll’s width, footage, adhesive and purchase count answer different buying questions. Estimate usage from the actual seal pattern, then select the tape and dispenser requirements for your carton.

Center strips = 2 × (seam length + 2 × overhang). H pattern adds 4 × (seam width + 2 × overhang). Usable roll inches = yards × 36 × (1 − waste %). This geometry is a quantity estimate, not an approved closure specification.
With a 12-inch length and width and two-inch overhang at each end, top-and-bottom center strips total 32 inches. The defined H pattern adds four 16-inch edge strips for 96 inches total. At 5% unusable footage, a 55-yard roll supplies 1,881 usable inches: approximately 58 center-sealed boxes or 19 boxes with this H pattern. Other closing methods require their own measured strip lengths.

| SKU | Listed width × length | Film thickness | Rolls per case |
|---|---|---|---|
| T902220 | 2 in × 110 yd | 2.2 mil | 36 |

Use each listing’s exact width and the dispenser’s supported width, core and outside diameter. One inch is 25.4 mm: an exact two inches is 50.8 mm, while 48 mm is approximately 1.89 inches. Commercial nominal sizes may differ; do not assume every 48 mm roll and every two-inch roll have identical width.
Acrylic, hot-melt, natural-rubber and water-activated tapes have different formulations and application requirements. This page assigns no universal temperature range, storage life, payload or bonding performance to an adhesive family. Confirm the exact product’s application and service specifications.
For cost per purchased yard, divide the merchandise total by rolls supplied × yards per roll. Include actual delivery for the same order when comparing delivered cost. Do not carry the 36-roll count from a two-inch case over to the 24-roll three-inch case.
Questions before ordering
Does three-inch tape seal more boxes per roll?
Width does not change the stated roll length. Under the same strip-length plan, yield comes from footage; adhesion and closing suitability need their own evaluation.
Will a longer roll fit my hand dispenser?
Confirm the actual core and outside diameter along with width. Roll footage alone cannot establish compatibility.
Is reinforced water-activated tape the same as acrylic tape?
It uses a different application method. Match the dispenser and moistening process separately from pressure-sensitive tape.
