Boxes per Corrugated Sheet Calculator
Compare two simple rectangular arrangements of box blanks on a corrugated sheet. The calculator uses whole blanks and checks a 90-degree rotation.

First time using this calculator?
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.
Best simple rectangular layout
Compares two uniform rectangular orientations only. Excludes gutters, gripper margins, grain-direction restrictions and irregular die-line nesting.
Yield = max(floor(sheet W/blank W) × floor(sheet L/blank L), floor(sheet W/blank L) × floor(sheet L/blank W))
max(floor(1,200/500) × floor(800/400), floor(1,200/400) × floor(800/500)) = max(4, 3) = 4Saved calculations stay in this browser. No account or cloud backup is created.

Vary one input and inspect best simple rectangular layout
All other entered inputs stay fixed. Ranges are your scenarios, not statistical confidence or supplier performance predictions. This uses the same validated calculator engine.
The formula, made clear.
The normal layout fits whole blanks across and along the sheet. A second calculation exchanges the blank dimensions, and the better count is reported. This gives a transparent rectangular layout comparison. It does not search mixed orientations, interlocking dielines or irregular nesting, and a mathematically larger count may be unsuitable if it conflicts with flute direction or converting constraints.
How to use this calculator
- 01
Enter usable sheet dimensions and the blank’s rectangular footprint.
- 02
Review the counts in both orientations.
- 03
Check the selected orientation against flute direction, gripper margins and cutting clearances.
A calculation you can check
The example compares unrotated and rotated rectangular blank layouts on the same sheet before a converter confirms the production arrangement.

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.
