This website is viewed globally and at the last time of looking had been used by people from 136 different countries.

The instructions and videos on this website show you the traditional methods of making a roman blind. Many countries have introduced safety regulations with respect to child safety, to reduce the threat of injury or strangulation to young children from the cords of roman blinds.

It is your responsibilty to find out what the regulations are for your country and modify these instructions to make your blind compliant with those regulations

Examples of safety advice and rules used by some countries of the world are:

  • Do not place furniture or beds near windows where children can climb up and access the blind cords.
  • For roman blinds with rod pockets greater than 20cms apart at any point a breakaway device must be used on each cord.
  • The cleat must be 150cms from the floor and accumulate all/most of the cord – only a single cord of no more than 20cms can hang below the cleat.
  • The bottom loop of the chain or cord must be 150cms from the floor and secured with a safety device OR If the operating chain/cord has a breakaway device then the bottom loop of the cord/chain can be 60cms from the floor.
  • Some countries require that all the blind's components have been tested and certified when used together.

  • Step 2: Calculate the Rod Pocket Positions
    Printable Worksheet
    Printable Worksheet

    You now have the finished blind width, length and a preferred Top Section size

    Next you need to calculate the number of rod pockets on the back of the blind and their positions. This will determine the style and depth of the blind when it is pulled up.

           

    The making process is the same for all 3 styles of blind, the only difference is the calculation of the number of rod pockets and their positions. In our tutorial videos we will be making a standard folds blind where flaps all line up in the up position. If you are making a cascading blind or a blind with an extended bottom flap, see the links at the bottom of the page for some extra information.

    DETERMINE YOUR HEADRAIL ALLOWANCE

    First we need to establish the Headrail Allowance

    The headrail allowance must be sufficient to cover the batten/headrail face and allow enough room under the blind for the folds to pull up to the correct position..

    We use a minimum of 6.5cm for headrail allowance for our headrails. As a general rule use an absolute minimum headrail allowance of:

    Headrail mechanisim: Headrail depth + 2.5cm
    Traditional wooden batten: Batten face + 3.5cm

    Please see our BLOG entry HEADRAIL ALLOWANCE EXPLAINED for more detail

    STANDARD FOLDS CALCULATION

    • Deduct the headrail allowance from the finished blind length to give the amount of fabric to be folded.
    • Divide the length of fabric to be folded by an odd number of fold sections - this will be the fold depth for that number of fold sections.
    • Add the headrail allowance to the fold depth to get the Top Section size.
    • Find the odd number that gives a Top Section size nearest your preferred Top Section size.
    • The odd number that was closest is now your number of fold sections and the answer in (2.) is now the depth of your folds.
    • The number of rod pockets = (number of fold sections -1) divided by 2

    PRO TIPS

    1. When choosing the best Top section size also consider your pattern if using patterned fabric. If possible choosing a depth that gives the best pattern placement when the blind is up.
    2. Adjust the headrail allowance slightly to tweak a Top section size. (never below minimum). Eg when trying to get 2 blinds of slightly different lengths the same size when pulled up, or getting the Top section the perfect size for the pattern.

    ROD POCKET POSITIONS

    With the number of rod pockets (3) and fold depth (12.0cm), we can now calculate the rod pocket positions

      EXTRA INSTRUCTIONS


    To calculate the rod pocket positions for a cascading blind please use our FREE Cascading Roman Blind Folds Calculator



    To calculate the rod pocket positions for a blind with a bottom flap please use our FREE Cascading Roman Blind Folds Calculator

    Enter your bottom flap size and a cascade increment of 0. The folds will then all line up with just the bottom flap hanging lower when the blind is pulled up.


    FAQs

    Yes that is normal,standard folds form a very slight cascade due to the way the rods and rings stack on each other when the blind is pulled up. The calculation of the rod pocket positions means that if the rods were all pulled up to exactly the same height, all the folds would be exactly inline. (see image)

    However that is not how a blind pulls up, the rods and rings stack on each other on the cord which creates a very slight cascade. If you were really wanting to make the folds line up exactly inline you would have to make make an adjustment to your rod pocket position calculation . It would involve making a mock up to see what the slight cascade depth is caused by the type of rod pockets and ring/breakouts you are using. Then recalculating the rod pocket positions to adjust for this. (this is not something we do)

    Your Questions & Comments

    Jane

    Thank you for your great tutorial. I have to make 4 Roman blinds using patterned material, should I cut the face fabric for all the blinds at the same time at the beginning of the project or as I go?

    SewHelpful:

    When I make up several blinds in the same fabric I tend to cut the face panels all at the same time to ensure that they all start at the same point in the pattern, as this avoids confusion later.
