Calcs For Cascade Roman Blind

[Julie Monty]

Hia
Doing some cascade roman blinds with a 46 and 3/4 drop, I just cannot get them right.
Would somebody please give me the perfect calculation, I would really appreciate it.
Regards

Hello Julie

I've assumed a 9cm allowance for your tracking and used a 5cm cascade.

119cm drop minus 9cm tracking leaves 110cm for pleating.

Working from the bottom: The calculations below do not allow for a seam allowance for making the rod pocket and I'd suggest you make a mock-up first.

1st rod pocket at 22.14cm from the hem

2nd rod pocket 34.28cm above the 1st

3rd rod pocket 29.28cm above the 2nd

Your top space will be 24.3cm plus 9cm track allowance giving a total 119cm (46 3/4")

If you need any further help just let me know.
