this calculator is really handy and useful but it does not cater for bigger returns eg my returns are 5.5 and 7.5 and overlaps are 3.5

THIS IS A GREAT IDEA BUT WHAT DO YOU DO IF YOU HAVE A 3 1/2 OR 4″ OVERLAP AND RETURN.

hi….take the flat width minus the finished width (what you want your panel to be in width) this equals the amount to be pleated…now take that amount and divide by the number of pleats you want …this will give you the size pleat…then take the flat width and minus your return and overlap or leading edge then divide that number by.. number of spaces you want ( remember… one less space than pleats) kinda of a rule a 54″ width panel after side hems will be a flat panel of 48″ should give five pleats and four spaces… a 6″ pleat and a four inch space is nice….or a 5 inch pleat and three inch space…on smaller width remember to start pinning pleats from the leading edge side…

HOW DO YOU CALCULATE IF YOU HAVE A 3 1/2, 4 OR 6 INCH RETURN AND OVERLAP

I thought the curtain started with a space and ended with a space. Therefore there would always be one pleat less. The calculator gave more pleats than spaces. Let me know sent the answer to my email

Hi Maria,

The spaces at the end of the curtains are called returns. The calculator

Then you have your pleats and spaces.

So… return – pleat – space – pleat – space – pleat – return

hope that helps

Hi Jenny, I hate to bother you but your pleat calculator is not working. Thanks, Penny

How do you mean? I just tested it and it seems to work ok. The calculator opens up in a pop-up window. Is your browser blocking it? Are you not getting a calculation? Let me know and I’m glad to help.

your calculator has only 3″ returns how do you calculate how many pleats if you have a 3.5″ return?

• ###### Jen Thoden
January 8, 2015 at 12:25 pm (2 years ago)

Hi Rachel,

The best way to do this is to make the value of both returns 0 and subtract the returns from the finished sewn panel width. The calculator is calculating the pleat size and spacing from pleat to pleat.

So, if your sewn flat panel is 54″ before pleating… and your returns are 3.5″ each. Instead of entering 54 in the first field, enter 47 and 0 for the return fields.

Hope this helps

Exellent calculator but I just need to know whether the calculator include the 10cm ease or do I need to add this into the desired width of my drapery panel after it has been pleated?

When using the calculator I have added the 10cm onto my width, but wanted to check.

Chris,

The calculator takes into account all the measurments you’ve entered. So your returns and the number pleats… to get to your desired width. The calculator will give you the numbers that… after pleating… will give you the edge to edge desired width. Not pleat to pleat. Hope that helps
