    FINISHED CURTAIN WIDTH

    For a pair of curtains the Finished Curtain Width for each curtain is half the pole length plus 5cm for ease.

    FINISHED CURTAIN LENGTH

    To calculate the Finished Curtain Length :

    • Decide where you will be attaching the curtain hooks on the curtain heading tape (there are usually 3 positions on pencil pleat tape).
    • Choose the position that will give you a Hook to Top distance nearest your measurement in Step 1, taking into account the curtain protrudes 0.5cm above the top of the heading tape.
    • Attach a hook to your heading tape and measure from the top of the attached hook to the top of the tape.

    The calculation for the finished curtain length is then.

    HOW TO CHOOSE THE FULLNESS OF YOUR CURTAINS

    When deciding how full we want our curtains to be we talk in terms of Fullness Ratio. Fullness Ratio is the ratio of the width of the curtain before pleating to its finished width when pleated or gathered. The higher the fullness ratio the more gathered and heavier the curtains will be.

    We recommend a Fullness Ratio of 2.4 to 2.5 for a pencil pleat curtain. Note that some heading tapes come with a recommended fullness ratio suggested by the tape manufacturer.
