Paper Calculators

Calculate Grammage from Basis Weight

 

Basis weight (in pounds) =
Basis Size (width) =
Basis Size (height) =
Grams per square meter =

Formula:

Basis Weight x 1406.5

=

GRAMS PER SQUARE METER

Basis Size

Example:

Convert 25x38, 60 lb. Offset Paper to grams per square meter

60 x 1406.5

=

88.8 Grams per square meter

25 x 38

 

Common Paper Basis Sizes
Bond 17 x 22 = 374 Square Inches
Text 25 x 38 = 950 Square Inches
  Cover 20 x 26   =     520 Square Inches
Index 25.5 x 30.5 = 777.75 Square Inches
Tag 24 x 36 = 864 Square Inches
Bristol 22.5 x 28.5 = 641.25 Square Inches
Newsprint 24 x 36 = 864 Square Inches



 

Calculate Basis Weight from Grammage

 

Grams per sq. meter =
Basis Size (width) =
Basis Size (height) =
Basis Weight (in pounds) =

Formula:

Grams per sq. meter x Basis Size

=

Basis Weight in Pounds

1406.5

Example:

Convert 90 G/M2 Offset Paper to Basis Weight of 25" x 38" size

90 G/M2 x (25 x 38)

=

60.1 Lb.

1406.5

Example:

Convert 110 G/M2 Translucent Paper to Basis Weight of 17" x 22" size

110 G/M2 x (17 x 22)

=

29.25 Lb.

1406.5

 

 

Determine an M Weight

M Weight is the weight of 1000 sheets, in pounds, of a basis sheet size.

 

Given size (width) =
Given size (length) =
Basis weight =
Basis size (width) =
Basis size (length) =
M Weight =

Formula:

Given Size x Basis Weight

=

Rounded Ream Weight x 2

=

M Weight

Area of Basis Size

Example:

Calculate the M Weight of a 28x40 70# Opaque sheet.

(28 x 40) x 70

=

83 lbs. x 2

=

166 lbs.

25 * 38

 




Determine Price per Thousand Sheets

 
Cost per hundred pounds =
M Weight =
Cost per thousand sheets =

Formula:

Cost per 100 lbs. x M Weight

=

Cost per Thousand Sheets

100

Example:

Calculate the cost per thousand sheets of a 25x38 60# Offset sheet that costs $48.00/cwt.

$48 * 120

=

$57.60 per Thousand Sheets

Pieces per Sheet Calculator

Calculating the Number of Pieces per Sheet for Your Project

Example:

How many 4.25 x 5.5 pieces can be cut from a 25 x 38 sheet?


25 38
4.25 5.5


Divide vertically: 25/4.25 x 38/5.5 = 5 x 6 = 30

 

Divide diagonally: 38/4.25 x 25/5.5 = 8 x 4 = 32

Your maximum number of pieces from this sheet is 32, without considering grain direction.


Start using the calculator.

Note: Always enter the smallest number first in each of the above cases.

Please enter the size of the sheet you are purchasing X

Please enter the size of your finished piece X


You will be able to produce pieces from your original sheet.

 

Note: This does not take into consideration grain direction. Sheet grain may be important. Consult your printer for grain direction requirements.
