Instructions for
Pinch Pleat Drapery Calculator
&
Drapery Pleating Device
(DYC70)
Definitions:
Width of material: Width of a single piece of fabric as it comes off the bolt.
A panel: Half of a pair of draperies, or the entire unit on a one-way draw. Usually it is multiple widths of
material sewn together.
Basic Principles:
Rod width: is the face of the rod, not including returns.
Side hem allowance is 1 1⁄2" double folded.
Seam allowances are 1⁄2" off each width of material at a seam.
Spaces between pleats
are kept the same and as close to 3 1⁄2" as possible.
Pleat sizes (or take up) are allowed to vary in order to hide seams.
Overlap : is 4". Return : is determined by the job. They are not counted as spaces in these instructions.
Fractional width is always placed on the return side of a panel.
Please read through Part I. and Part II. of the instructions before starting. For making rail roading
draperies, read Part III.
Part I.
Pinch Pleat Drapery Calculator
On page 17 and 18, we supply workroom forms for Even Pair of Draperies; One Way Draw and for Off
Center Draw draperies. You may copy them for your own use. Workroom Form pads for Even Pair of Draperies and One Way Draw
ll in the fabric width, rod
width, return and overlap allowances. Fill in the remaining information as you go along.
Step 1
Step 2
Calculate the panel width and record it on the workroom form:
For a two way, center draw drapery:
Panel width excluding return and overlap = (Rod Width ÷ 2) - 2".
For a one way panel:
Panel width excluding return and overlap = Rod Width - Overlap.
The overlap is the space from the side hem to the first pleat at the master carrier.
For a pair of off center draperies, widths of two panels have to be determined separately. See the
Workroom Form for an Off Center Pair of Draperies on page 18.
Step 3
Step 4
On the Pinch Pleat Drapery Calculator, locate the chart for the fabric width (36", 45", 48" or 54").
Slide the insert up until the double pointer (
in window C.
) points at the number 1 in the “# of Widths” column
Slide the insert down slowly while reading the numbers in the “Panel Width” window (window D) until
the desired panel width appears. It is most desirable, if the desired panel width appears near or within 3 1⁄2" to
3 3⁄4" space size range.
Sometimes the number of widths per panel has been predetermined, then just slide the insert down until
the ( ) points to the predetermined number of widths and read the numbers in the “Panel Width” window
(window D). If the desired panel width does not appear in Window D, slide the insert down to the next setting.

Example 1
Procedure for When Number of Widths Per Panel
Have Not Been Predetermined
Use 54" wide fabric to make a pair of drapery
panels. The rod width is 110". Allow for 4" return
and overlap. Excluding the return and overlap, the
panel width will be 53".
On the calculator, locate the chart for 54" fabric.
Starting with ( ) pointing at 1, watch window D and
slowly slide the insert down until 53" is within the
range of numbers appearing near the 3 1⁄2" space
size.
Record the information in the Workroom Form
(see right):
3 widths of 54" fabric are required to construct
each panel. The total number of spaces per panel is
15 and space size is 3 5⁄8". Before hemming, trim 3"
off the overlap width and 5" off the return width.
The return, middle and overlap width will have 4,
6 and 5 spaces respectively. See page 6 for how to
apply the Pleating Device.

For Panels Requiring 9 or More Widths
The pinch pleating calculator can figure a drapery panel up to 8 widths of material. For 9 or more
widths, see example 3.
Example 3:
Use 54" wide fabrics to make a pair of drapery panels. The rod width is 464". Allow for 4"
return and 4" overlap. Excluding return and overlap, the panel width will be 230", exceeding the
limit of the Pinch Pleat Drapery Calculator.
If the number of widths allowed for each panel is predetermined, skip Step 1.
Step 1. Calculate the number of widths required to construct each panel: You may use any
fullness as requested by your customer. Here we choose 2.5 fullness.
230" x 2.5 = 575"
The panel width before pleating will be about 575" wide.
Fabric Width:
Rod Width:
575" ÷ 54" = 10.6
Return:
4¨
Round to 11. It will take 11 widths of 54" fabric.
Step 2. Find out the total number of spaces per panel:
On the calculator, locate the chart for the 54" fabric.
Slide the insert, so ( ) is pointing at the first number 8
under the # of Widths column in window C. The number
to the right of ( ) is the total number of spaces on just
8 widths, which is 45. The number in the parenthesis is
the number of spaces on each additional width. In this
case, it is (6).
Since the calculator only goes up to 8 widths, and
we need 11 widths, there will be 3 additional widths with
6 spaces each for a total of 18 additional spaces. The
total number of spaces for the panel will be 45 + 18 = 63.
Step 3. Figure out the space size: The finished panel
width excluding return and overlap is 230", and the total
number of spaces is 63.
230" ÷ 63 = 3.65"
In the Decimal Inch Converting Chart, 3.65" is
found to be between 3.625" and 3.75". Choose the
larger of the two: The space size is 3 3⁄4".

Part II. Drapery Pleating Device
The Pleating Device is essentially an elastic belt attached with plastic sleeves. Each sleeve
represents a space (Fig. 5). This device always lets one mark a pleat right next to a seam, so the
pleat will conceal the seam.

Assemble widths of material together, trim, seam and hem each drapery panel. Sew the drapery
heading as usual.
Lay the top edge of the drapery header along the edge of the worktable. For an even pair of
draperies, lay them face to face and do both of them at the same time. Keep the overlaps to your
right.
Mark the overlap and return.
Start at the overlap width and work with as much of the panel as the length of your table permits.
You may use erasable fabric marking pen (Stk#: PM21 or PM22) to mark the draperies.
Set the First Sleeve:
Position the 0" on the first sleeve of the
pleating device on the overlap mark on the
panel; clamp the sleeve and panel to the
table. This sleeve is not counted as a space
(Fig. 6). For the remaining steps, read the

Procedure for Marking a Pair of Drapery Panels When Window A Shows 0
To mark a pair of drapery panels as described in example 1 (page 3) on a 12' long
worktable:
Seam 3 widths of 54" fabric together. Total width is 160" (2 seams take away 2"). After trimming (Trim off 3" from overlap width and 5" off from return width, respectively) and
hemming (2 hems: take away 6" total), the panel width becomes 146". A 12' worktable
can accommodate the entire panel. Sew the drapery header as usual. Mark the return
and overlap. Keep the overlap to the right. Position the pleating device so the 0" mark
on the first sleeve is aligned with the overlap mark (Fig. 6) and clamp.
Starting with the next sleeve, count 5 sleeves and position the 0" mark on the fifth
sleeve on the seam and clamp (Fig. 7-A).
On the second width, count 6 sleeves after the clamped sleeve, and align the 0" mark
of the sixth sleeve on the seam as before (Fig. 7-B).
On the third width (return width), count four sleeves after the clamped sleeve, then
pick up the next sleeve and position the 3 5⁄8" mark on that sleeve on the return mark and
clamp (Fig 7-C). Recount the sleeves to make sure there are 15 between return and
overlap marks and mark the pleats as in Figure 9.
Example 5
Procedure for Marking a Pair of Drapery Panels When Window A Shows s
To mark a pair of drapery panels as described in example 2 (page 3) on an 8' long
table:
Seam 2 1⁄2 widths of 54" fabric together and the total width is 135" (2 seams take
away 2"). Trim off 2" from the return width (the half width) then hem (2 hems take away
6" total) the panels. The panels are 125" wide. The 8' table can not accommodate the
whole panel. We will mark the first width (the overlap width) first, then reposition the
panel and mark the middle width and the last half width (the return width) together.
Sew the drapery header as usual. Mark the return and overlap. Position the panels
on the table as described in the instruction.
Set 0" mark of the first sleeve on the overlap mark and clamp (Fig. 6).
Starting from the next sleeve, count 5 sleeves, move one more sleeve to the left and
position the 4 1⁄4" mark on that sleeve on the seam (because there is an s) and clamp
(Fig. 8-A). Now mark the panel as in Figure 9. Release all the clamps
Reposition the panel so the first seam is now at the right end of the table. Align the
4 1⁄4" mark on the first sleeve on the seam and clamp. Starting with the clamped sleeve,
count 6 sleeves, move one more to the left and position the 4 1⁄4" mark on that sleeve on
the seam and clamp (Fig. 8-B).
On the third width (return width): counting the clamped sleeve, count 2 sleeves, move
one more sleeve to the left and position the 4 1⁄4" mark from that sleeve on the return
mark and clamp (Fig. 8-C). Mark the pleats as in Figure 9.

Part III. Drapery Panels Made by Rail Roading Fabric
1. Estimate the Amount of Fabric Needed for a Panel:
+
+
+
=
Panel width excluding return and overlap x Fullness (typically 2.5)
Overlap (typically 4")
Return (typically 4")
Allowance for the two side hems (typically 1 1⁄2" doubled on each side for a total of 6")
The amount of fabric needed to cut off the bolt for a panel.
2. Mark the Panel
Hem the panels and sew the header as usual. Lay the top edge of the drapery header along the
edge of the worktable, keeping the overlap to your right, and return to your left. Mark the return and
overlap.
Step 1 Recalculate the fullness. Measure the distance from the overlap mark to the return
mark. This is your panel width before pleating.
Fullness = Panel width before pleating ÷ Finished panel width
Step 2 Estimate the pleat size. Go to the
Charts for Rail Roading Drapery Panels on page
14. Find the fullness in Chart 1. Directly underneath, is the estimated pleat size.
Step 3 Mark the last pleat. From the right side
of the return mark, measure one pleat size (calculated in step 2) and mark it as the last pleat mark
(Fig. 10).
Last Pleat Mark
Return Mark
Step 4 Divide panel into workable sections.
If the worktable is large enough to accommodate the
entire panel, go on to step 5.
0
1
2
3
4
5
Fig. 10
If the worktable can not accommodate the entire panel, the panel has to be divided into 2
or more equal sections. Measure the distance from the overlap mark to the last pleat mark.
Mark the center. You have divided the panel into 2 equal sections. If your worktable can
accommodate one section, continue on to the next step.
If the worktable can not accommodate one section, each section needs to be further
divided into two. Measure the width of each section. Divide this number by 2. That is half of
the section width. Use the half of section width to find the middle point in each section and
mark. You may keep dividing each section into two until one section is small enough for the
worktable to accommodate.
Count the number of the sections in a panel.
Step 5 Determine the # of spaces and the space size. Go to the Charts for Rail
Roading Drapery Panels on page 14 through 16. From Chart 2 through Chart 6, find the
appropriate chart with correct number of sections. In the chart, locate the fullness. The range
from two columns to the left and two columns to right is the range of desired fullness. For
example, if the fullness is 2.5, the desired fullness range is 2.7 to 2.3. Under the desired
fullness range, find the number closest to the desired finished panel width excluding return
and return. If no exact match is found, use the number slightly larger.
Follow the finished panel width across to the # of spaces column on the left. The bold
number is the total number of spaces required for the entire panel and the number in parenthesis is the number of spaces required for each section.
Follow the finished panel width down to the bottom of the chart and you will find the space
size in bold letters.

Step 6 Apply the pleating device. Work on one section at a time, starting at the overlap.
For First Section: Take the first space sleeve of the pleating device, position the 0" on
the overlap mark and clamp. This sleeve is not counted as a space (Fig. 11-A). Starting with
the next sleeve, count each sleeve as one space until reaching the number of spaces required
for one section. Stretch the device to the section mark and align 0" mark on that sleeve with
the section mark and clamp (Fig 11-A). With fabric marking pen, mark the fabric at the 0" mark
and at the predetermined space size mark on each sleeve (Fig. 9). Release all the clamps.
Reposition the panel, so the next section is laying flat on the worktable.
Do not count this
sleeve as a space

a space belonging to this middle section. Starting with the next sleeve, count each sleeve as
one space until reaching the number of spaces required for one section. Stretch the device to
the section mark at the left side and align 0" mark on that sleeve with the section mark. Clamp
(Fig. 11-B) and mark.

Example 6:
Procedure for Marking Rail Roading Drapery Panels
Estimate the Amount of Fabric Needed for a Panel: To make a pair of drapery
panels for a rod that is 188" wide, with 4" return and 4" overlap. The pleated panel width
excluding return and overlap will be:
(188"÷2) - 2" = 92".
If the customer asks for 2.5 fullness:
92" x 2.5 = 230"
230" + 4"(Overlap) + 4"(Return) + 6"(Allowance for side hem)=244"
One needs to cut a 244" long piece of fabric to make one panel. After hemming and
sewing the header, you are ready to mark the panels.
Step 1. Recalculate the fullness: The length measured from overlap mark to return mark
is 230". The desired panel width excluding return and overlap is 92".
230 ÷ 92 = 2.5
The calculated fullness is 2.5
Step 2. Estimate the last pleat size: In the Chart 1, underneath the 2.5 fullness, you will
find estimated last pleat size is 5 1⁄4"
Step 3. Mark the last pleat: Measure 5 1⁄4" from the return mark and mark it as the last
pleat mark (Fig. 10).
Step 4. Divide the panel into workable sections: The 8' long worktable can not
accommodate the entire panel. Measure the length from overlap mark to the last
pleat mark. It is 224 3⁄4". Half of that is 112 3⁄8". From overlap mark measure 112 3⁄8"
and mark. The panel is now divided in to two sections. Each is 112 3⁄8" long. The
8' table still can not accommodate one section. You need to further divide each
section into two. Half of 112 3⁄8" is 56 3⁄16", round to 56 1⁄4". Using this number, find
the mid point in each section and mark. The panel is now divided into 4 sections.
Each section is about 56 1⁄4" wide. An 8' worktable can accommodate one section.
Step 5. Determine the number of spaces and space size: Since there are 4 sections
in a panel, go to Chart 4. For Panels Divided into 4 Sections on page 15. In the
chart, locate the calculated fullness 2.5. The desired fullness range is 2.7 to 2.3. In
that range you will find 93" is closest to 92". Toward the left, you will find the total
number of spaces is 24, and the number of spaces in each section 6. At the bottom
of the chart, you will find the space size 3 7⁄8".
Step 6. Apply the Pleating Device: Start from the section next to the overlap. Lay the
panel so the first section is laying flat on the table with overlap at your right. Align 0"
mark on the first sleeve with the overlap mark (Fig. 11-A). Clamp. Starting from the
next sleeve, count 6 sleeves. Stretch the pleating device and align 0" mark on the
sixth sleeve with the first section mark (Fig. 11-A). Clamp. Mark panel at 0" mark
and at 3 7⁄8" mark on each sleeve (Fig. 9). Release the clamps.
Reposition the panel so the second section is laying flat on the table. Align 0" mark
with the right side section mark. Clamp. Starting from the next sleeve, count 6
sleeves. Stretch and align 0" mark on the sixth sleeve with the section mark at the
left side as described in the instructions. Clamp and mark as before (Fig. 11-B).
Continue in the same fashion on the remaining sections. On the last section, clamp
the first sleeve and count the sleeves as before. After counting 6 sleeves, stretch
the device and align 0" mark on the sixth sleeve with the last pleat mark. Clamp and
mark (Fig. 11-C).

Part IV. Care & Tips for Using Drapery Pleating Device
1. Care:
• Do not leave the Drapery Pleating Device stretched for prolong period of
time.
• Do not rest hot iron on the Pleating Device.
• Choose clamps with cushion bumpers. Position clamp foot evenly on the
Pleating Device sleeve, then clamp. Do not let sleeve twist while clamping.
• Always hold Pleating Device while releasing clamp. After releasing clamp,
gently return the Pleating Device to its original un-stretched position.
• Fan fold Pleating Device neatly after each use.
2. Tips:
• Our Quick Set/Release Clamps (Stock #: QC10) are indispensable for
clamping down the Pleating Device as described in the instructions. You
need at least two clamps. However, having an extra 2 or 3 more will enable
you to mark more than one width at a time. It is convenient and worth the
time you save.
• Our Erasable Marking Pen (Stock #: PM21) is very handy for working with
the Pleating Device. Using the eraser end of the marking pen, a mistaken
mark can be erased by a single stroke. The marks last about two to
fourteen days depending on the fabric, if you do not erase them.
You can also use our straight pins (Stock #: TP44 and TP48) to mark the
pleats.
