Measuring for Roller Blinds
How to Measure For Face Mount
(for fitting your blind outside the window frame)
- Measure the width from the outer edge of the architrave to the opposite edge.
- Measure the drop from the top of the architrave to where you want the blind to finish.
If you do not have architraves (timber frame) around window
- Measure the opening and add at least 100mm to allow the cloth to go past the opening. (100mm will give 35mm of cloth each
side past the opening)
- Measure the opening and add at least 100mm to the drop to allow the blind to be mounted above the opening.
How to Measure For Recess Mount
(for fitting your blind inside the window frame)
- Measure the width from the inside of the window frame from left side to right side. Making sure to measure at the top of
the reveal and not the bottom of the window, as this is where the brackets will be mounted.
- Measure the drop from the top of the inside recess to the base of the inside sill.
Make sure you have enough depth to mount the blind inside the frame. 60mm will be sufficient. Less will result in the blind
protruding out of the recess. Minimum depth required is 30mm.
Do not make any deductions as our factory will do this to ensure a perfect fit.
Measuring for Roman Blinds
- Start by measuring the Width from the outer edge of the architrave to the opposite edge.
- Measure the Drop from the top of the Architrave to the where you want the blind to finish.
For shorter drop windows we recommend that you take the blind 50-100mm below the sill. Watch for any obstructions such as
desk or bed.
For full length windows we recommend that you measure to 20mm off the floor. This will give enough clearance and allow the
blind to have room to settle overtime. For drops over 2410 we recommend 30mm clearance.
- We recommend that you add 100-150mm to the drop of the blind, so you can mount the blind above the architrave to allow the
pack to clear as much glass as possible when raised. This will allow more light into the room and is important when blinds
are on doors, to allow for clearance.
- We recommend that you add 40-100mm each side of the architrave. This will help reduce the gap at the side of the blind,
providing better light control and more privacy.
IMPORTANT - We only recommend that Roman Blinds are Face Fitted and not Recessed inside the window. This
is in accordance with the Australian Soft Furnishings Guidelines.
Measuring for Vertical Blinds
How to Measure For Face Mount
(for fitting your blind outside the window frame)
- Measure the width from the outer edge of the architrave to the opposite edge.
- Measure the drop from the top of the architrave to where you want the blind to finish. We recommend 10mm off the floor and
50-100mm below the frame.
- We recommend that you take the track past the architrave each side. This will give more privacy and better light control.
The distance you take the track is entirely optional. We highly recommend that you add at least 60-100mm. Make sure that
you don't have any obstructions.
How to Measure For Recess Mount
(inside the window frame)
- Measure the width from the inside of the window frame from left side to right side. Making sure to measure at the top of
the reveal and not the bottom of the window, as this is where the track will be mounted.
- Measure the drop from the top of the inside recess to the base of the inside sill. Measure in 3 places Left, Centre and
Right and take the smallest of the three measurements.
Depth Required: You will need a depth of 135mm for the blind to fit neatly inside the recess for 127mm
slats and 97mm depth for 89mm slats. Minimum depth required for both slat sizes is 50mm. This will result in the blind slightly
protruding out of the recess but will not detract from the product.
Important: Do not make any deductions as our factory will do this to ensure a perfect fit.
Measuring for Basswood & Timberlook Blinds
How to Measure For Face Mount
(for fitting your blind outside the window frame)
- Measure the Width from the outer edge of the architrave to the opposite edge.
- Measure the Drop from the top of the architrave to where you want the blind to finish.
Important: If measuring to the top of a sill or to the floor, deduct 15mm from the drop so the
base rail is free to rotate when closing the blind. (Measurement B - Drop to sill or floor - 15mm for clearance)
If you do not have architraves (timber frame) around window
- Measure the opening and add at least 20mm to allow the blind to go past the opening (10mm each side). (Measurement A + 20mm)
- Measure the opening from the top to where you want the blind to finish. Add at least 50mm to the drop to allow the blind
to be mounted above the opening. If measuring to the floor, deduct 15mm so the base rail is free to rotate when closing
the blind. (Measurement B + 50mm for height - 15mm for clearance)
How to Measure For Recess Mount
(for fitting your blind inside the window frame)
- Measure the width from the inside of the window frame from left side to right side. Making sure to measure at the top of
the reveal and not the bottom of the window, as this is where the brackets will be mounted.
- Measure the drop from the top of the inside recess to the base of the inside sill.
Depth Required: You will need a depth of 65mm for the blind to fit neatly inside the recess. With the Valance
a total of 80mm. The minimum depth required for fixing the screws is 45mm, this will result in blind slightly protruding
out of the recess but not effecting the aesthetics of the product.
Important: Do not make any deductions as our factory will do this to ensure a perfect fit.
Measuring for Honeycomb Blinds
How to Measure For Face Mount
(for fitting your blind outside the window frame)
- Measure the width from the outer edge of the architrave to the opposite edge. Make sure to do this at the top of the window
where the blind will be mounted.
- Measure the drop from the top of the architrave to where you want the blind to finish. Repeat this across the window and
take the smallest of the three measurements.
If you do not have architraves (timber frame) around window
- Measure the opening and add at least 50mm to allow the cloth to go past the opening.
- Measure the opening and add at least 50mm to the drop to allow the blind to be mounted above the opening.

Measuring for Curtains
Measuring for curtain width & drop
The width is easily measured by providing us with the track size you require. You can take the track past the architraves
as much as you like for better light control & clearance of windows when curtains are open.
Handy Hint - Try entering small variations to your widths at our website, as you might find the price reduces
due to the amount of drops to the fabric required. So altering your measurement by a few millimetres may show a price reduction.
Curtains look best hung to the floor, alternatively you can hang them to the sill or below the sill for shorter windows.
- Measure to the floor
- Measure 100-150mm below the sill (watch out for obstructions such as desk or toy box)
- Measure to the sill Our hooks will lift the curtains above the track allowing the curtain to hang neatly just above the
floor or sill, eliminating the chance of it dragging.
- Eyelet & Tab Top Curtains are mounted above the architrave. Add 100mm to measurement A, B, or C to
allow for the Tab & Eyelet to clear the glass.
Always measure the drop in 3 places across the window to ensure the window is level. Measure Right, Centre & Left hand
side and use the shortest of the 3 measures. This is for Measurement A & C lengths only (floor or sill).
Measuring for curtains using existing track or pole

For one way tracks measure A + B = Total Curtain Width

For 2 way track with centre overlap measure A + B + C + D = Total Curtain Width

For Rods measure between the decorative ends
Measuring curtain drops for certain header types for existing rods & tracks
Tab Top Heading
Tab Top headings have a 100mm long tab which is included in the curtain drop and are suitable for poles up to 45mm in diameter.
Measure from the top of the pole to the floor, sill or below the sill.
By adding the curtain to your rod, it will automatically lift it off the floor or above your sill. Don't make any deductions.
Eyelet Heading
The eyelet will fit rods up to 30mm in diameter. The inner edge of the eyelet is set down 30mm from the top of the curtain.
Measure from the top of the rod to the floor, sill or below the sill as shown in the diagram above and then add 30mm to
your drop.
Pinch Pleat, Inverted Pleat & Pencil Pleat Headings
When using a existing curtain track, measure from the top of the track to the floor, sill or below as shown
in the above drop diagram.
When using a curtain rod, measure from the underside of the decorative ring where the curtain hooks into.
Then measure, to floor, sill or below sill as shown in diagram above.
Measuring for Valances on existing track
Measure the Valance rail width (not the curtain track). This is normally wider than the curtain track.
Measure A + B + C = Total Valance Width
Measuring for Pelmets & Valances
Points to Know
- Pelmets & Valances generally go past the architraves either side.
- You will need to make the width 40mm wider than the product you are covering (20mm each side)
- The measurement we refer to is always the inside box width (IBM)
- The projection is the distance the Pelmet or Valance will come out from the wall
- The Fascia size is the height of the Pelmet face
View the specifications of each individual product at our website for further details on projection, fascia etc. You will
also find details of sizes to order to cover specific products, such as curtains, roller blinds and more.
Measuring for Soft Valance on existing Valance Rod
A + B + C = Valance size
Measuring for multi panel windows, sliding & bifold doors for Roller Blinds
Sliding Door
Recess Mount (inside the frame)
Most sliding doors do not have enough depth to allow you to mount the blind inside the recess. You will need to have at
least 60mm’s, although you can get away with a minimum of 30mm’s, allowing the blind to project forward out of the recess
into the room.
Also make sure that the door doesn’t have a lip in the centre of the door, preventing recess mounts. If recessing your roller
blinds, we recommend that you front roll the cloth to help clear of the handle when operating.
Measuring
We only recommend one blind when recessing. If you have two blinds, you must make sure the blind beside the door, is not
in the down position when opening the door, otherwise it will easily get damaged.
Architrave Mount
(outside frame)
You have an option of having 1 or 2 blinds.
- Measure the width from the outside edge of the frame, left to right.
- If you require 2 blinds, then measure from the outside left architrave edge, to the centre of the mid panel for Blind 1.
Repeat from the right side to the centre of the panel for Blind 2. Make sure the two measurements add up to the overall
width (A)
Note: Not all panels are even and simply halving the overall width may cause a slight imbalance of the
2 blinds. It is always better to measure each panel, then making sure the 2 add up to the overall width. (B1 + B2 = A)
Measure the drop from the top of the architrave to where you want the blind to finish.
Chain controls will be on the left for the left hand blind and the right for the right hand blind.
3 Panel Door
As you do not want to have a gap between the cloths over the glass, we do not recommend 2 even blinds on 3 panel doors/glass.
It is always best to have the cloth gaps, over the timber or aluminium mullions.
Your options are;
3 individual blinds
2 Blinds - 1 Blind over 2 panels and the other over 1 panel
1 Blind if the width does not exceed 3000mm
3 Individual Blinds
A1 - For the left hand blind, measure from the outside edge of the left architrave to the centre of the panel mullion.
A2 - For the central blind, measure from the centre point of the left mullion to the centre point of the right
mullion.
A3 - For the right hand blind, measure from the outside edge of the right architrave to the centre of the panel
mullion.
B - Measure the overall width from the left hand architrave edge across to the right hand architrave edge.
Make sure all 3 individual measurements add up to the overall width.
Important-Australian Child Safety Law awareness for 3 Panel Sliding Doors
It is against Australian child safety laws to allow a unsecured chain on a blind. All blinds must have a child safety device
fitted and secured in place to prevent the risk of child strangulation. If the door is in the middle of a 3 panel window,
this may prevent the child safety device from being secured on the middle bind. There are only two options that you can
take here;
- The central blind must have a shorter chain no longer than 1.6m from the floor. You can request this in the comments field
at the checkout of our website. Please let us know the length required.
- The central blind must be ordered with a multi link, connecting the operation to one of the outer blinds. Our website has
the option of adding a multi link in the Design and Order section. A multi link allows the middle blind to operate in unison
with the adjoining blind.
- Failure to request one of the above 2 options will leave your blinds at risk of causing child strangulation and breaking
the Child Safety Laws. Blindsonline can not be held accountable for your failure to secure the blinds as requested.
2 Individual Blinds
Decide which side the 2 panel and 1 panel blind is best suited. Follow the same measuring procedure as listed above.
1 Individual Blind
Simply take the overall width x drop. It is recommend that a single blind does not exceed 3000mm width. Keep in mind the
traffic going through the door and the operation of a single large heavy blind.
Bifold Doors
- The amount of panels will determine the combination of blinds.
- Do not split the blinds over the middle of a glass panel, always divide over the timber or aluminium mullion
- Make sure the chains have a position to secure the child safety device. Due to the operation of the doors, 2 Blinds are
ideally suited.
- Make sure measurement A & B add up to the overall width of the bifold doors
Bifold Doors Recess Mount
There is often not enough depth for mounting the blinds inside the recess and face mounts are generally the method recommended.
However if you do have a deep recess and you would prefer to mount your blinds this way, simply follow the same principals
above for dividing the binds in the centre of the door frames to the combination you prefer.
Measurements are taken from inside the frame as shown above
Measuring for Corner Windows
At a Glance
- We require your measurements in millimeters
- Write the width x drop
- Make sure to take the deduction off the butt blind, to allow for the distance of the through blind.
When mounting your blinds into a corner window, one blind will run through and one blind will butt into the other blind,
as shown in the diagram below.
First you must decide which blind will be the one to run through. We generally recommend that the blind running through
is the one that is facing the front of the house or where you want to achieve the most privacy, to stop vision down the
gap between the butting blind.
Important - When ordering your blinds the measurement must have the projection depth subtracted from the
butt blind to obtain the proper ordering width. You will be ordering the finished blind size. This distance to be subtracted
will depend on the type of product. See chart below

Measuring for Panel Blinds
At a glance
- Always use a metal tape measure
- Always write down your measurements width x drop. Take care not to reverse them.
- We require your measurements in millimetres
- Measure every window, as they may have a slight variation that will effect your window furnishing from fitting perfectly
How to Measure For Face Mount
(for fitting your blind outside the window frame)
- Measure the width from the outer edge of the architrave to the opposite edge.
- Measure the drop from the top of the architrave to where you want the blind to finish. We recommend 10mm off the floor and
50-100mm below the frame.
- We recommend that you take the track past the architrave each side. This will give more privacy and better light control.
The distance you take the track is entirely optional. We highly recommend that you add at least 300mm, to enable the panels
to clear the glass as much as possible. Each panel is 600mm wide. Make sure that you don’t have any obstructions such as
light switches or bookcases etc.
