Paper Caliper Calculator

Estimate paper caliper (thickness) in points and mils based on basis weight, sheet size, paper type, and bulk factor. Useful for approximating paper thickness for printing, packaging, and mailing applications.

Paper Basis Weight Calculator

Calculate paper basis weight in gsm from sheet dimensions, sheet count, and total stack weight. Enter the paper size, number of sheets, and total weight to estimate the basis weight of the paper.

GSM to lb Paper Calculator

Convert paper weight from grams per square meter (GSM) to pounds based on paper grade and basis size. Enter the GSM value and choose the paper category to estimate the equivalent US basis weight in pounds.

Cardstock Weight Calculator

Estimate cardstock basis weight in lb from sheet dimensions, paper weight in grams, quantity, and paper grade. This calculator converts the measured total weight of a stack into an equivalent basis weight using the standard 500-sheet basis for the selected grade.

Microns to GSM Calculator

Convert material thickness in microns to grams per square meter (GSM) using material density. GSM is calculated from thickness and density, with common material presets included for quick estimation.

Points to GSM Paper Calculator

Convert paper thickness in points (pt) to estimated paper weight in GSM, with options for paper type and finish. This calculator provides a practical estimate because point-to-GSM conversions vary by paper density and coating.

Paper Roll Diameter Calculator

Calculate the outside diameter of a paper roll using core diameter, paper thickness, roll length, and packing factor. This helps estimate the final roll size for converting, printing, packaging, and inventory planning.

Paper Roll Length Calculator

Calculate the approximate length of paper wound on a roll using the roll’s outside diameter, core diameter, and paper thickness. Choose the unit system that matches your measurements.

Paper Roll Weight Calculator

Calculate the estimated weight of a paper roll using roll diameter, core diameter, roll width, and paper basis weight. The formula estimates paper area from the difference between the outer and core cylinder volumes and converts basis weight in GSM to total roll weight.

Cost Per Page Calculator

Estimate the cost per page for writing, design, or printing work based on total project cost, number of pages, turnaround speed, content complexity, and revision rounds.
