Replace the example values with figures from your supplier sheet or measurements. Choose the unit beside each value. Results update as you type; fix any highlighted field before using the result.
GSM means grams per square metre. Net weight excludes the core and other packaging. MOQ means the minimum order quantity. An optional field can stay blank unless the result you need depends on it.
Prices keep the selected currency; changing its label does not convert an exchange rate. Save or export the result after checking your inputs.
Help with process loss on gross tape
Use a measured or supplier-confirmed percentage where possible. Check whether it applies to gross input or finished output; the formula below shows the basis used here.
Whole rolls to purchase
Rolls = ceil(Tape/box × Boxes ÷ (1 − Loss%) ÷ Usable length/roll)
per = 2.6; boxes = 1000; roll = 66; loss = 5 → Whole rolls to purchase = 42 rolls; Gross tape requirement = 2736.842105 mSaved calculations stay in this browser. No account or cloud backup is created.

The formula, made clear.
Add loss on gross input, then round up whole purchased rolls. Do not confuse the consumed-tape allowance with unused stock after rounding.
How to use this calculator
- 01
Confirm measured tape per box, boxes to seal, usable tape length per roll, process loss on gross tape.

A calculation you can check
2.6 m × 1,000 boxes with 5% loss and 66 m rolls requires 42 rolls.
- Measured tape per box
- 2.6 m
- Boxes to seal
- 1000 units
- Usable tape length per roll
- 66 m
- Process loss on gross tape
- 5 %
per = 2.6; boxes = 1000; roll = 66; loss = 5 → Whole rolls to purchase = 42 rolls; Gross tape requirement = 2736.842105 mCheck the displayed formula and units against your quotation. Use measured GSM, net weight and actual layout dimensions where available. Default densities are planning assumptions, not certified material properties. Calculated cost does not certify strength, compatibility or safe loading.
