INTRODUCTION
The new
Quilter’s FabriCalc
Design and
Fabric Estimating Calculator is perfect for
all of your design needs.
The
Quilter’s FabriCalc
easily calculates
your material yardage so you can focus on
creativity.
Your Calculator Helps You Solve:
• Quilt Fabric Yardage for any size or
style of quilt, including:
• Backing Yardage
• Border Yardage (mitered or straight
corners)
• Drop Yardage (mitered or straight
corners)
• Binding Yardage
• Yardage for various sizes of Blocks,
including Sashing, if needed.
• Yardage, cut sizes (including seam)
and number of strips to cut for various
sizes of Squares, including 1/2
Square and 1/4 Square Triangles.
• Yardage, cut sizes (including seam)
and number of strips to cut for 45˚
and 60˚ Diamonds.
• Also calculates number of Squares or
Diamonds that can be cut from any
size of fabric you want to use – make
the most of your “stash” of fabric.
• Easily keep track of how much fabric
you need for various colors of fabrics;
store up to six different types of fabrics.

GETTING STARTED
Your calculator is designed to work
with common fabric measurements for
easy calculation of various quilt
requirements.
Your calculator is defaulted to display
the calculated results in fractional format. You can also set your calculator
to display in decimal or metric format
(see Preference Settings for details
on how to change formats).
Basic Operation and Entry Keys
N — On/Clear Key
Turns on power. Pressing once
clears the display. Pressing twice
clears all temporary values.
F — Off Key
Turns all power off, clearing all
entered Quilt, Block, and Square
values. Your calculator is also
designed to shut itself off after
about 8-12 minutes of non-use.
+ - x ÷ =
Arithmetic operation keys. See
Basic Math section for details.
%
Four-function (+, –, x, ÷) percent
key. See Percentage Calculations
section for details.
POCKET REFERENCE GUIDE — 2
0 – 9 and •
Keys used for entering digits.
/ — Fraction Bar
Used to enter fractions. Fractions
may be entered as proper (1/2, 1/3,
1/4, 1/8) or improper (7/6, 9/3).
They will be displayed in 1/8, 1/4,
1/3, or 1/2 increments. You can also
use / to toggle between fractional
and decimal displays.
c
Used to convert between units of
measure or access secondary
functions.
R
Used for recalling entered or stored
values.
Fabric Default Values
These keys are used for storing
values used for proper calculation of
fabric Yardage.
c + — Seam
Stores the Seam width (default: 1/4
Inch). This value is used in the
material functions for proper
material calculations.
POCKET REFERENCE GUIDE — 3
c 8 — Binding Cut
Stores the Binding Cut Width
(default: 2 1/2 Inches). This value is
used in the Binding calculation
found in the Total Quilt Yardage
function. This value should be
stored with seam allowance
included in the stored value (no
seam allowance adjustments are
made to the Binding calculations).
c - — Fabric Width
Stores the Fabric Width (default: 40
Inches). This value is used in all of
the material functions for providing
the proper Yardage based on the
stored Fabric Width.
c ÷ — Backing +
Stores the Backing Overage (default:
4 Inches). This value is used in the
Backing calculation found in the Quilt
Yardage function, and is added to all
four sides of the quilt to accommodate the extra material needed for
the quilting process.
Yardage and Meterage Keys
y — Yardage
Enters or converts to
Yardage (linear
Yards
).
Yardage
is based on the
stored Fabric Width (default is 40
Inches). Also used with the / key for
entering fractional Yardage values
(e.g., 4 y 1 / 2).
(Cont’d)
POCKET REFERENCE GUIDE — 4
Note:
Repeated presses after ctoggle
between fractional and decimal values
(e.g.,
4 y 1 / 2 c y
converts to 4.5
linear Yards (“yardage”); press
y
again to
return to fractional Yardage).
m — Meterage
Enters or converts to linear
Meters
.
Meterage
is based on the stored
Fabric Width (default is 40 Inches,
but you may store any fabric width
desired (e.g. 1 Meter).
Convert Fractional Yardage to
Decimal Yardage
Convert 8-1/8 Yards to Decimal Yards.
Then convert back to Fractional Yards.

Dimensional Measurement Unit Keys
The following keys are used for
entering units of measure, with ease
and accuracy:
i — Inch
Enters or converts to
Inches
. Also
used with the / key for entering
fractional Inch values (e.g., 9 i
1 / 2).
Note:
Repeated presses after ctoggle
between fractional and decimal Inches (e.g.,
9 i 1 / 2 c i
converts to 9.5 Inch;
press
i
again to return to Inch-Fractions).
ç — Centimeters
Enters or converts to
Centimeters
.
c 9 — Millimeters
Enters or converts to
Millimeters
.
Entering Linear Dimensions
When entering fractional values for
Inches, identify your entry by using the
i key
.
Enter fractions by entering the
numerator (top), pressing / (fraction
bar key) and then the denominator
(bottom). Press N after each
example.

Entering Area Dimensions
You can enter or calculate area values
for Inches, Centimeters, or Millimeters.
For instance, if you are working with a
piece of fabric that is 40 Inches x
10 Inches (400 sq. Inches), you can
enter this area for use in the Square,
Triangle, and Diamond functions
(see sections for examples).

stored values.
CALCULATING QUILT YARDAGE
The following keys are used to
calculate Yardage including backing,
binding, borders, and drops.
t
Enters finished width of quilt top for
calculating the top Yardage of
material required.
T
Enters finished length of quilt top for
calculating top Yardage required. A
second consecutive press of T
calculates the diagonal of the finished top quilt based on the entered
Top Width and Top Length.
POCKET REFERENCE GUIDE — 8
ƒ
Enters the finished Border Width
(4-sided border). This value then
calculates, upon repeated presses,
the following:
Press
Result
1 Border Yardage
2 Number of Strips
(to cut for the Border)
3 Border Strip Cut Width
Note: Border values are based on the Corner
(Miter vs Straight) Preference Setting (default:
Mitered Corners). See Preference Settings for
details.
d
Enters the finished Drop Width
(3-sided drop). This value then
calculates, upon repeated presses,
the following:
Press
Result
1 Drop Yardage
2 Number of Strips
(to cut for the Border)
3 Drop Strip Cut Width
Note: Drop values are based on the Corner
(Miter vs. Straight) Preference Setting (default:
Mitered Corners). See Preference Settings for
details.

*Backing Yardage does not include repeats
.
**If Border or Drop is not entered, these values are
not displayed in the above Total Quilt Yardage list.
***All calculated items include adjustments for
seam allowance, except for Binding (it is
assumed the seam allowance is included in the
stored Binding cut value used for calculating
Binding Yardage and number of strips).
Note: Entries of top width, top length, border,
and drop are semi-permanent entries; that
means, they do not clear until you turn off your
calculator or until you enter a new value. You
can enter zero to clear these values if you have
previously stored values.

Quilt Top Length, Top Width,
Border and Drop
Find the top Yardage of a standard
queen-size quilt (80 Inches length x
60 Inches width), with a finished
Border width of 4 Inches, and a finished Drop width of 18 Inches.
Then calculate the following values:
• Top Yardage
• Backing Yardage
• Border Yardage, number of strips
and strip cut width
• Drop Yardage, number of strips
and strip cut width
• Binding Yardage, number of strips
and strip cut width
Note: You will notice the Drop is outside of the
Border (this is typical for a standard bedspread). If
you need your Drop to be included inside of the
Border, add your Drop values to your Top Width
and Top Length (do not enter Drop separately).
