Measuring Guidlines

Roller Blinds

Single/Double Roller Blind

Inside Mount

It is industry standard for a blind fitting into a window reveal to sit flush with the front of the reveal. The factory will make the appropriate deductions for the product type and fixing method.

Width

▪ Measure neat internal width of the reveal
▪ Measure at three width points – top middle and base of reveal. This will be the bracket to bracket measurement. Use the smallest width measurement

Drop

▪ Measure neat internal drop of the reveal
▪ Measure at three drop points – left, middle and right of reveal. It is not critical to use the shortest drop for this product but client should be advised if window is “out of square”. Blinds can only be made square so if window is out of square it may result in irregular light gaps around the blind. Advise your client.

Measure Roller 1

Note – The blind fabric will be narrower than the bracket to bracket measurement. Refer to “Side/Light Gap” notes in Specifications. If the blind is an inside mount there will be light gaps on each side of the blind.

 

Outside Mount

Blind Fitting onto Architrave

Width

▪ Measure from outside edge of architrave to outside edge of opposite architrave at three width points. Use the largest width measurement

Drop

▪ Measure from top of architrave to base of lower architrave or floor. Measure at three drop points. Use the longest drop measurement

Measure Roller 2

Note – The blind fabric will be narrower than the bracket to bracket measurement. Refer to “Side/Light Gap” notes in Specifications. Some architrave will be visible on each side of the blind. Measuring and installing the blind on the wall past the architraves will avoid the architraves being visible on the sides when the blind is drawn down (check for solid fixing point for brackets).



Outside Mount

Blind fitting onto wall

Width (No architrave present)

▪ Measure minimum of 50mm past each side of window opening at the top







Width (Architrave present)

▪ Measure minimum of 30mm past edge of the architrave

Depth (No architrave present)

▪ If fitting blind into plaster or concrete – measure minimum of 70mm above window opening to a minimum of 50mm below window opening, or to the floor
▪ If fitting blind into brick, measure from the top of the first brick to a minimum of 50mm below window opening, or to floor

Measure Roller 3

No Architrave

Measure Roller 4

With Architrave

Linked Roller Blinds



Inside &Outside Mount

  • Use standard measuring principles for Inside and Outside Mount
  • Measure each blind individually, and provide these measurements. The factory will make the appropriate deductions for the link bracket. Indicate on paperwork that blinds are linked
  • Always measure and record the blind sizes starting from left to right across the window area

 





Measure Roller 5

DO NOT measure the complete area to be covered and then divide by the number of blinds, as the blinds may not always be the same size.

Link the blinds in front of the window mullion or framing where possible. This is where the gap between the blinds will be, and will provide a better appearance and assist in light blocking.

Note – Always have windows/ doors closed when measuring, to ensure the blinds line up with the mullion/ frame.

Butting Blinds

Blinds fitting side by side not using link bracket

  • Apply the same measuring principles as for the Linked Roller blind and state on the paperwork that the blinds are ‘Butting together’. There will be a gap between the blinds, refer to the ‘Side/ Light Gap’ notes in the specifications

 

Corner window

Inside Mount

Follow standard measuring principles and check that the reveal is deep enough to fit the roller system that you are using. Refer to the projection notes in the specifications. Check for anything that may impede operation of blind e.g. window locks.

Option One (Through Blind with Butting Blind)

  • Determine which window should be the main window for privacy, light block or aesthetic reasons. This will be the “through” blind. The gap between the blinds will sit in front of the window that the “butting” blind covers
  • Measure at the front of the reveal
  • Measure the width of Blind 1 from point A to B
  • Measure the width of Blind 2 from point C to D at the front of the reveal. Both blinds will sit flush with the front of the reveal
Measuring Corner 1

Option Two (Butting Blinds)

  • Measure at the front of the reveal
  • Measure the width of Blind 1 from point A to B
  • Measure the width of Blind 2 from point C to D at the front of the reveal. Both blinds will sit flush with the front of the reveal
Measuring Corner 2

Note

  • Front roll will provide better coverage and a smaller corner gap than back roll. A gap in the corner where the blinds meet cannot be avoided. Advise your client
  • It is not advisable to situate the control chains in the corner, as they will be difficult to access for operation
  • Thick fabrics and/or large drops may result in the fabric protruding past the mounting bracket when rolled up. Please allow for this when calculating deductions
  • Option one provides better light block, as there will be less gap where the ‘butting’ and ‘through’ blinds meet


Outside Mount

Option One (Through Blind with Butting Blind)

  • Determine which window should be the main window for privacy, light block or aesthetic reasons. This will be the “through” blind, as the gap between the blinds will sit in front of the window that the “butting” blind covers
  • Measure blinds 1 and 2 across the outside face of the corner window, along the surface to which the blinds will be fitted
  • Measure the width of Blind 1 from A to B by measuring from the outside edge of the architrave to the corner
  • Measure the width of Blind 2 from C to D by measuring from the outside edge of the architrave to the corner
  • Deduct the projection of Blind 1 from the Blind 2 width measurement. Refer to the Easy Reference Guide for product projections. Blind 2 will “butt” up to the front of Blind 1
Measuring Corner 3

Note: Refer to measuring guide for Outside Mount Blind Fitting onto Wall if there are no architraves or if you require blinds to fit onto wall.

Option Two (Butting Blinds)

  • Measure Blinds 1 and 2 across the outside face of the corner window, along the surface to which the blinds will be fitted
  • Measure the width of Blind 1 from A to B by measuring from the outside edge of the architrave to the corner
  • Measure the width of Blind 2 from C to D by measuring from the outside edge of the architrave to the corner
  • Both Blind 1 and Blind 2 require the projection to be deducted from each width measurement. Refer to the Easy Reference Guide for product projections

Note 

  • Refer to measuring guide for Outside Mount Blind Fitting onto Wall if there are no architraves or if you require the blinds to fit onto the wall
  • Front roll will provide better coverage and a smaller corner gap than back roll. A gap in the corner where the blinds meet can not be avoided. Advise your client
  • It is not advisable to situate the control chains in the corner as they will be difficult to access for operation
  • Option one provides better light block, as there will be less gap where the ‘butt’ and ‘through’ blinds meet
  • Where architraves are present, measurements should be taken on the face of the architrave

 

Bay window

Inside Mount  (135 Degree Bay Windows only)

There will be considerable light gaps in bay window corners between the blinds, as the Roller blind fabric is shorter than the bracket to bracket blind measurement.

Follow standard measuring principles, and check that the reveal is deep enough for the Roller blind system that you are using. Refer to the projection notes for this product in the specifications.

Width

  • Measure blinds 1, 2 & 3 across the front of the reveal
  •  Measure from Point A to B
  •  Measure from Point B to C
  •  Measure from Point C to D

Note  – This is the standard manner for fitting Roller blinds into a bay window. There are other options that may achieve increased coverage. You should discuss options with your installer. Front roll will decrease the corner light gaps.



Outside Mount (135 degree Bay Windows only)

Width

  • Measure blinds 1, 2 & 3 across the outside face of the bay window along the surface to which the blinds will be fixed
  • Measure from Point A (edge of architrave) to Point B
  • Measure from Point B to Point C
  • Measure from Point C to Point D (edge of architrave)
  •  If no architrave is present, add 50mm to side window opening widths
Measuring Bay 2

Note – Front roll will decrease the corner light gaps.

Take the following deductions from these measurements:

  •  Como Roller Blind
    o Deduct 27mm from blinds 1 & 3 and deduct 54mm from blind 2
  •  Como2 Roller Blind
    o Deduct 54mm from blinds 1 & 3 and deduct 108mm from blind 2
  • Acmeda Roller Blind
    o Deduct 27mm from blinds 1 & 3 and deduct 54mm from blind 2

Note – Bay windows in older homes often have considerable timber framing and moulding at the top of window frames so it is critical that you inspect where the blinds are to be fitted before you take measurements.

 

Roman Blinds

Single Roman Blinds

Inside Mount

It is industry standard for a blind fitting into a window reveal to sit flush with the front of the reveal. The factory will make the appropriate deductions for the product type and fixing position.

When drawn up the Roman Blind folds will sit back further than the headrail. This will vary depending on the drop and style of the blind, and could be as much as 70mm. Ensure that the reveal is deep enough.

Width

  • Measure neat internal width of the reveal
  • Measure at three width points – top, middle and base of reveal. Use the smallest width measurement, as the blind will be drawing up the length of the reveal and may rub or jam at narrowest point if the wider measurement is used

Drop

  • Measure neat internal drop of the reveal
  • Measure at three drop points – left, middle and right of reveal. Use the shortest drop measurement
  • Advise client if window is out of square, as this can cause irregular light down the sides of the blind and/or across the base of the blind. The blind can only be made square
Measuring Roman 1

Note – When fully drawn up the Roman Blind will stack up to an approximate depth of between 300mm to 450mm. This will vary according to the blind drop and the operation system. Show the client the approximate stack depth in the reveal.

 

Outside Mount

Blind Fitting onto Architrave

Width

  • Measure from outside edge of architrave to outside edge of opposite architrave
  • Measure at three width points – top, middle and base of window. Use the widest width measurement. Add 20mm to overall width measurement to ensure no architrave is visible down the sides of the blind

Drop

  • Measure from top of architrave to base of lower architrave or floor
  • Measure at three drop points – left, middle and right. If blind is finishing at base of architrave, use longest drop and add a minimum of 30mm. If blind is going to the floor, use shortest drop
Measuring Roman 2

Note – When fully drawn up, the Roman Blind will stack up to an approximate depth of between 300mm to 450mm. This will vary according to the blind drop and the operation system. Blind will sit in front of the window area. Show the client the approximate stack depth in the reveal.



Outside Mount

Blind fitting onto wall

Roman Blinds are often fitted onto the wall above the window even if architraves are present. This is done to reduce the depth of the blind hanging in front of the glass when drawn up, and avoids hindering the light and view through the window. This is particularly relevant when blinds are fitting over doors, as the stack depth is likely to prevent easy walk through access if fitted onto the architrave.

Width (No architrave)

  •  Measure minimum of 50mm past the window opening at the top

Width

  • Measure minimum of 30mm past each edge of the architrave

Drop

  •  If fitting onto plaster or concrete, measure a minimum of 70mm above the window opening to a minimum of 50mm below window opening, or to the floor
  • If fitting into brick, measure from the top of the first brick, or from the top of a higher brick where required

Note –  Roman Blinds will often be fitted 100mm to 200mm above the window opening.

Corner window

Some operational difficulties will occur with Roman Blinds fitted in a corner window application. Both blinds may not be able to be fully drawn up at the same time due to the fabric folds protruding past the face of the blind when drawn up. The drawn up blind may push into the other blind, causing it to sit incorrectly. As the blind is being drawn up it may rub the fabric of the other blind, resulting in some minimal wear to the fabric.

Refer to the Corner Window measuring for Roller Blinds as a guide. Refer to the Easy Reference Guide for the product projection that will need to be deducted from blinds if outside mount.

Butting blinds, rather than using a “through” blind can be a better option. There will be minimal light gap.


Bay Window


Some operational difficulties will also occur with Roman Blinds fitted into a bay window application. All blinds may not be able to be fully drawn up at the same time. If one or both of the side blinds are drawn up, the centre blind will only draw up to the base of the side blind. If the centre blind is drawn up, the side blinds will only draw up to the base of the centre blind.

It is recommended to use brackets to determine measurements for outside mount applications.

panel glides

It is very important to show your client where the panels will sit on the window and how much of the glass area they will cover. This factor may influence how many panels you decide on, as increasing the number of panels will decrease the width of each individual panel. When there is more than one blind in the same room area, it is advised to keep the panel widths (rather than the number of panels) as similar as possible to maintain consistency in product appearance. To determine an approximate width of the panel, divide the blind width by the number of panels.

Single Opening Panel Glides

Inside Mount

It is industry standard for a blind fitting into a window reveal to sit flush with the front of the reveal. The factory will make the appropriate deductions for the product type and fixing position.

Check that the reveal is deep enough for the track to fit into. Refer to the projection notes in the specifications. The depth required will vary with each different track size. Ensure there are no protruding window handles/locks etc. that will interfere with the sliding action of the panels.

Width

  • Measure neat internal width of reveal
  • Measure at three width points – top, middle and base of reveal. Use the smallest width measurement

Drop

  • Measure neat internal drop of reveal
  • Measure at three drop points – left, middle and right of reveal. Use the shortest drop measurement. Advise client if window is out of square
Meauring Panel 1

Outside Mount

Blind Fitting onto Architrave

Width

  • Measure from outside edge of architrave to outside edge of opposite architrave
  • Add a minimum of 100mm to each side. This provides better light block and privacy and ensures that no architrave is visible down sides of blind

Drop

  • If going to floor, measure from top of architrave to floor. Measure at three drop points – left, middle and right of area. Use the shortest drop measurement. Advise client if the drop height varies across the area as this will result in an irregular light gap along base of blind
  • If going to base of window, measure from top of architrave to the base of lower architrave. Add minimum of 70mm to drop to provide better light and sun block
Meauring Panel 2

Outside Mount

Blind Fitting onto Wall

Width

  • Measure a minimum of 150mm past each side of the opening

Drop

  • If fitting the blind into plaster or concrete – measure a minimum of 70mm above the window opening to a minimum of 100mm below the window opening or to floor
    • If fitting blind into brick – measure from the top of the first brick to a minimum of 100mm below the window opening or to floor

Note – Outside mount Panel Glides can be extended past the window opening to have panels sitting in front of wall and not obstructing the window area. This is achieved by increasing the width of the Panel Glide to extend past the window on one side, or if centre opening, to extend past on both sides. Check for any obstructions e.g. light fittings.

Corner window

Refer to the Corner Window measuring for Roller Blinds as a guide. Refer to the Easy Reference Guide for the product projection that will need to be deducted from the “butting” blind.

Measuring Zebra 9

NoteThis is the standard manner for fitting Zebra Blinds into a bay window. There are other options that may achieve increased coverage. You should discuss options with your installer

Outside Mount

135 degree Bay Windows only

The following instructions are to be used as a guide for Outside Mount Bay Window blinds. The most accurate procedure for measuring for this application is to install the brackets first, and measure from bracket to bracket.

Follow standard measuring principles. There will be considerable light gaps in bay window corners between the blinds, as the Zebra Blind fabric is narrower than the provided width measurement.

 

Width

  • Measure blinds 1, 2 & 3 across the outside face of the bay window along the surface to which the blinds will be fixed
  • Measure from Point A (edge of architrave) to Point B
  • Measure from Point B to Point C
  • Measure from Point C to Point D (edge of architrave)
  • If no architrave is present, add 50mm to side window opening widths

Take the following deductions from these measurements:

  • Blind 1
    o Deduct 38mm total
  • Blind 2
    o Deduct 75mm total
  • Blind 3
    o Deduct 38mm total

Note – Recommended deductions include 1.5mm clearance per blind / per meet. Bay windows in older homes often have considerable timber framing and moulding at the top of window frames so it is critical that you inspect where the blinds are to be fitted before you take measurements.

Pelmets

Pelmets are generally ordered with the blinds they are to fit over. The factory will manufacture the pelmet based on the measurements supplied for the blind. Outside mount pelmets will be 10mm wider than the blind with returns supplied as standard. Inside mount pelmets will be supplied at the opening width measurement supplied. If a specific sized pelmet is required, please specify the outside length dimensions on your order form.
