Mike’s Measuring Tips

  • Use a steel tape measurer for accuracy. Make sure it’s straight and tight when you take your measurements.
  • From the front door, turn left. This becomes window 1 and then work clockwise around your house. Repeat upstairs if necessary. Also add your room name to each blind as you order them.
  • Measure at the top of the window frame where the blind is to be installed. This is where your brackets will be placed.
  • Always measure in millimetres (mm) – remember it’s OK to be 1mm short, but you can't be 1mm too long
  • Measure every window, even those that appear to be the same width and height.
  • The measurement you provide is the outside edges of the brackets – not the fabric width
  • Do not take any deductions (iSeek Blinds will do this for you)

Sizes – Minimums & Maximums

We manufacture custom roller blinds to a huge range of sizes. To ensure you always get a great result, we have minimum and maximum dimensions for our roller blinds, depending on the fabric range.

* Please note:   A small selection of our fabrics have a maximum width of less than 3,000mm.  Please refer to our Fabric Specifications for Roller Blinds for all details.

How to measure for your single roller blinds

  • How to Measure - Inside Mount

    Mike’s Tip! When measuring inside mount roller blinds, ensure that you have at least 60 mm clearance inside your window recess so you have enough space for your blinds to sit neatly inside. For living areas, we recommend inside mount roller blinds and for bedrooms inside mount your sunscreen or light filter roller blind and outside mount your blockout blind – this will give you the greatest control over privacy, glare and room darkening.

    Measure your width
    • Measure the hard width across the top inside the window recess as this is where your brackets will be fitted.
    • Note your measurement to the exact mm
    Measure your drop
    • Measure the hard drop from the inside top of your window to the inside bottom of your window
    • Note your measurement to the exact mm
    • Don’t worry if you measure the drop a little bit longer, you will
  • Customise and design your blind

    For more details on all our design choices, refer to our product specifications page

    • Roll Direction: iSeekBlinds recommends inside mount roller blinds are front rolled, this means that the fabric rolls off the front of the roll tube like a waterfall to avoid any knobs, winders or the inner window frame that may obstruct the blind. This will also create a softer, more balanced look.
    • Control type: Decide if you want a chain drive to control your blind or if you want to upgrade to a motorised control. If you choose a chain we will recommend a length for your chain drop, but you can choose a longer/shorter chain if you need it. You also need to decide which side you want your chain or motor on. For motors make sure you choose the side that is the easiest to access when you need to charge it.
    • Colour Choices: You will have the choice of a white, black or anodised bottom rail, make sure you note this for each blind as you take your measurements. Your choices of chains are either black or white as standard or you can upgrade to a metal chain or a stainless steel chain, which is highly recommended for wet areas or if you live near the coast.
    • Spring Assist: All blinds with a chain drive over 1800mm wide should be ordered with a spring assist. This will ensure your blinds glide smoothly up and down with minimal effort and will limit wear & tear on the components.
  • How to Measure - Outside Mount

    Measure your width
    • Measure the width on the outside edges of your architrave from one side to the other.
    • Measure from the top of the architrave as this is where your brackets will be fitted.
    • For windows without an architrave measure from where you want the brackets to be installed and the measurement will be from the outside of one bracket to the outside of the other bracket.
    • Note your measurement to the exact mm
    Measure your drop
    • Measure the hard drop from the top outside edge of the architrave to the bottom outside edge of the architrave. This measurement may be increased if you want the blind to drop past the bottom of your window frame or to the floor.
    • Note your measurement to the exact mm
    • Don’t worry if you measure the drop a little bit longer, you will be supplied with ball stops for your chain so you can choose exactly where you want the bottom of the blind to sit. You can also easily control the bottom limit with motorised blinds.
  • Customise and design your blind

    For more details on all our design choices, refer to our product specifications page

    • Roll Direction: iSeekBlinds recommends outside mount roller blinds are back rolled, this means that the fabric rolls off the back of the roll tube this ensures the fabric stays close to the architrave for maximum privacy and light control.
    • Control type: Decide if you want a chain drive to control your blind or if you want to upgrade to a motorised control. If you choose a chain we will recommend a length for your chain drop, but you can choose a longer/shorter chain if you need it. You also need to decide which side you want your chain or motor on. For motors make sure you choose the side that is the easiest to access when you need to charge it.

    • Spring Assist: All blinds with a chain drive over 1800mm wide should be ordered with a spring assist. This will ensure your blinds glide smoothly up and down with minimal effort and will limit wear & tear on the components.
    • Add on a Pelmet: Consider finishing off your roller blind with one of our designer pelmets. Not only will it look great, it will hide the tube and stop dust from collecting on top of the blind. Note: Pelmets are only compatible with outside mounted, back rolled roller blinds.
  • How to Measure - Corner Windows

    Got a corner window that you need to measure?
    We found the best way to show you the various ways to measure your corner windows is by showing you. Whether you want inside or outside mount watch this video with Mike and he'll take you through the process step-by-step, ensuring you achieve the outcomes you deserve!

    You can then follow the instructions we have provided in either our Inside or Outside Mount sections on this page, depending on what you have chosen for your window.

  • How to Measure - Pelmets

    To create a contemporary look and add the finishing touch to your roller blinds add one of our designer range of pelmets. Pelmets will neatly cover the top and front of the roll tube protecting your roller blinds from dust as well as hiding the roll tube.

    Mike’s Tip! Pelmets are only available on outside mounted blinds and can only be back rolled. They are available on our Single and Linked Roller Blinds only.

    Dimensions: Our Pelmet 95 range protrudes 85mm out from the architrave / wall and has a height of 95mm

    Option 1 - Extended Mount

    Best for achieving greater light control and privacy and blends the fabric into the wall without the disruption of the architrave.

    • Measure from the outside edge of the architrave to the outside edge of the architrave. Add an extra 30mm past the outside edge of the architrave on both sides (if space permits) - adding a total of 60mm to your overall width. This will then extend your fabric past the architrave for full coverage on both sides and reduce light gaps
    • This will become the width measurement you enter when placing your order and represents the finished size of the pelmet, not the fabric.
    • Note your measurement to the exact mm.
    Option 2 – Flush Mount

    The pelmet sits flush with the outside edge of the architrave

    • Measure from the outside edge of the architrave to the outside edge of the architrave for a flush finish.
    • This will become the width measurement you enter when placing your order and represents the finished size of the pelmet, not the fabric.
    • Note your measurement to the exact mm.
  • Sizes – Minimum & Maximums

    We manufacture custom roller blinds to a vast range of sizes. To ensure you always get a great result, we have minimum and maximum dimensions for our roller blinds, depending on the fabric range.

    * Please note: A small selection of our fabrics have a maximum width less than 3,000mm. Please refer to our Fabric Specifications for Roller Blinds for all details.

  • Extra wide roller blinds

    If your window is wider than 3,000mm, linked rollers blinds enable you to place blinds side by side across your windows, bifold or stacking doors. You can keep any chains clear of the centre and the gap between the blinds is greatly reduced with the use of our linking brackets.

    Our linked layouts give you the option to link 2, 3, or 4 blinds for a maximum width of 12,000mm. Link to Linked Roller Blinds / Product Specifications Page specification-linked-roller-blinds
