Step-by-Step: Measuring for Curtains
1
Choose Your Mounting Style
Ceiling Mount:

Clean, floor-to-ceiling finish

Enhances height and maximises blockout

Ideal for both sheer and blockout curtains
2
Measure the Width
Ceiling Mount:

Measure wall to wall

Deduct both cornice widths

Subtract an additional 20mm (10mm each side) for clearance
Ceiling Mount – wall to wall
3
Measure the Drop
Ceiling Mount:

Measure from the ceiling to the floor

Take three measurements – left, centre, and right

Record the shortest drop
Ceiling Mount Drop
Wall Mount:

Mounted just below the ceiling or cornice

Flexible bracket options

Works well with outside-mounted blinds
2
Measure the Width
Wall Mount:

Measure from wall to wall or the full width you’d like your track to span

Subtract 20mm for clearance
Wall Mount – Wall to Wall
Wall Mount – Window Width
Mike’s Tip:
Deduct 20mm from your total width to allow 10mm clearance on each side. This ensures a perfect fit.
3
Measure the Drop

Measure from your intended bracket fixing point (just under the cornice) to the floor

Take three drop measurements – left, centre, and right

Use the shortest measurement
Always measure in millimetres (mm)
Don’t take any deductions – even for different hems and finishes, we make those adjustment for you.

Choose Hand-Drawn or Motorised Curtains
Hand-Drawn:

Up to 10,000mm wide

1–4 panels (equal or custom widths)

Optional wand control: 750mm, 1000mm, 1250mm, 1500mm
CurtainIQ Motorised:

Tap or Smart options

Battery powered, wire-free, DIY-friendly

Stack options: left, right, or centre

Choose motor side for centre opening
Mike’s Tip:
Choose your stack direction before ordering – it determines how your curtains open and how the motor is installed.
Note: Centre opening motorised curtains require two motors – one for each panel.
5
Select Your Track & Brackets
Track Style:

Sleek, square-profile design

White or black

Ceiling or wall mount

Tracks over 3600mm supplied in two joined sections
Wall Mount Brackets:

Standard: 20–50mm

Extension: 60–100mm

Extra Extension: 85–130mm
Allow 90mm total depth for your curtain
6
Choose Your Curtain Finish
Drop Finish Options:

Touching the Floor

Off the Floor: approx. 10mm shorter

Puddled: approx. 20mm longer (sheers only)
Hem Style Options:
Blockouts:

Overlocked hem (recommended to reduce flaring)
Sheers:

Lead weight hem

80mm sewn hem
Mike’s Tip:
An overlocked hem helps your blockout curtains fall cleanly and avoids flaring at the base.

Label Each Window
Start at your front door and move clockwise around your home. Label each window with its room name (e.g. Bedroom 1, Living Room) to stay organised during ordering.
Mike’s Measuring Tips

Use a steel tape or laser for best accuracy

Measure every window – even if they look identical

Record in millimetres (mm)

Clearly mark Width and Drop

Deduct 20mm from the width for clearance – wall to wall & ceiling mounted

Don’t make any other deductions

You’re measuring for the track, not the fabric
