Handy Hints
When measuring, always look out for things like window handles or tiles and take their position into account if necessary. This is so you can be sure of the perfect fit. All our blinds can be fitted into the face of your window frame or wall, or into the top of the lintel. This gives you complete control over the positioning of your blind.
What you will need
1. Tape measure (metal ones are best)
2. Pen and paper
Things to remember
1. Always use a steel tape for accuracy - make sure the tape measure is straight and tight when you take your measurements
2. Always measure in millimeters (mm)
3. Measure all windows, even those that appear to be the same width and height
4. Don't forget the stacking height of your chosen blind
5. Do not take any deductions
Face Measurement
1. For all types of blinds follow these instructions if you want your blind to hang outside the window recess.
2. Measure the exact drop from the top of where you want your blind to be to the bottom. Usually a 50mm overlap is sufficient. Note down the measurement.
3. Measure the exact width of where you'd like your blind to be. usually a 50mm overlap for coverage is sufficient. Note down the measurement.

Make sure your width is measured before the height and is clearly marked.

Check measure three times over to make sure there are not any errors.
Note the side you wish the controls to be that they are easily accessed.
Recess Measurement
1. For all types of blinds follow these instructions if you want your blind to hang inside the window recess:
2. Measure the drop by taking the measurement from the top of the recess to the window sill in 3 places as shown. Write down the shortest measurement - this is the one we'll use. Then take off a 10mm deduction.
3. Measure the width of the recess from wall to wall in 3 places as shown. Write down the shortest measurement. Then take off a 10mm deduction.

Make sure your width is measured before the height and is clearly marked.
Corner Windows
When two outside mount verticals meet in a corner, or when other inside mount products meet in a corner where there is only glass (no gibboard), there can be a privacy problem. That's due to a gap where the products "meet". In order to minimize the problem, consider making one product bypass the other, then specify the other product to butt into the first. (See illustration.)
French Doors/Arched Windows
The wider and taller you specify your product, the better your privacy, insulation, and light control. You also need room 60mm x 20mm vary per blind for the mounting brackets at the top, and the optional hold-down brackets at the bottom. Consider mounting the window treatment a bit higher than you'd think so when the blind is raised it blocks less of your view. Add at least 100mm at the top.

For the width, add at least 20 to 30mm on both sides of the glass. Usually the deadbolt latch, however, will constrain the width you'd prefer. The product will usually fall just inside the deadbolt. In the case of a lever handle, the product will slip between the handle and the door.

All products will work on either a wood or metal door. For metal doors, you'll probably need "metal screws" designed for attaching to metal doors, which are normally hollow.
Tile & wooden obstructions
Sometimes tile or trim wrap around into the window, usually several inches up from the bottom. This is common near kitchen sinks (back-splashes) and bathtubs. Most products can be cut by the manufacturers on the products' sides to accommodate this. There is a slight surcharge depending on the product and whether the cutout is on one or both sides.
Sliding Doors
All our blinds can be specified to mount either within the door frame or over it on the wall. When determining this, consider whether the handle is an obstruction, and the amount of depth available. There is sometimes moulding or trim near the baseboard which may have to be removed, or at least taken into consideration when determining width. For an outside mount it is normally sufficient to measure about 80mm wider on both sides. The wider you specify, the better your privacy, insulation, and light control. For the height, specify about 100mm above the top of the frame.
Shallow sill depth
30mm minimum sill depth is required to fasten all brackets and the minimum depth necessary for a flush mount (where the product does not protrude into the room. It has been our experience, however, that 60mm is necessary to securely anchor brackets for timber venetians and creation woods; you'll need to angle the screw back towards the glass and occasionally add one extra bracket.

Stacking Height (Outside Mount Only)
To preserve your view, you may choose to have your blinds stack completely off the window when it's fully raised. To do this, you will need to add the approx height of the stack to your measurement.
Roller Blind Controls
Spring Motor or Side-Winder (with control chain)
Check your window or sliding door opening before making your selection. If it opens left to right– select roller side-winder blind controls to be on the right side. This is called a right controls (R.C.)

If it opens right to left– select the roller side-winder blind controls to be on the left side. This is called a left controls (L.C.)

Sliding doors left side opening -two blinds are required. Left side blind with left hand controls (L.C.) right hand side blind is recommended to have right hand control.
Sliding door right side opening-two blinds are required. Right side blind with right side controls (R.C.) left hand side blind with left hand controls. If the window or sliding door opens from the centre to each end. This is called a centre-opening window - it is recommended that three roller blinds are used for this window or sliding door opening.
