HP Roll Print Calculator (841mm Roll)

Enter your document size, then copy the results into the printer driver and print window.

Measurement unit

Side A

Tip: you can paste a number like 126.50

Side B

Doesn’t matter which way round you enter them

How to find document size (quick): look for something like “Page size” / “Document Properties” / “Drawing Size”.

Calculator link (for sharing): Open in new tab

Logic: tries both orientations, picks the one with the least reduction to fit within 841mm. Never upscales above 100%.
