How to Measure Double Curtains
Get the right measurement for every window
Getting Started
Measure, customise, and install with confidence – we’re here to help you every step of the way. Double curtains are perfect for combining sheers and blockouts. Whether you’re installing hand-drawn or CurtainIQ motorised curtains, ceiling or wall mounted – we’ve made it simple.
Before you start, have you?
Let’s make sure you’re all set:
Chosen your mounting style – Ceiling Mount or Wall Mount?
Decided on hand-drawn or motorised operation?
Decided on a double curtain setup?
Ordered your free fabric samples?
Downloaded our Check Measure Worksheet?
Downloaded your Curtains DIY Measuring Templates?

Clearance to factor in:
A double curtain setup requires approx. 180mm depth
Step-by-Step: Measuring for Double Curtains
1
Choose Your Mounting Style
Ceiling Mount (Top Fix):
Both tracks are mounted directly to the ceiling
Clean, seamless floor-to-ceiling look
Sheer and blockout tracks installed in parallel (separate tracks)
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 (Face Fix):
Tracks are mounted using supplied double bracket sets
Brackets are pre-spaced to support both tracks at correct projection
Ideal for layered curtains over doors, windows, or roller 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
Wall Mount:
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).

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 in black or white
Suitable for ceiling or wall mount
Tracks over 3600mm are supplied in two joined sections
Ceiling Mount:
Tracks are installed separately in parallel
Allow 180mm total depth
Wall Mount:
Includes double wall brackets to hold both tracks
Allow 180mm total projection
6
Step 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:
Overlocked Hem (for blockouts only)
80mm Hem
Lead Weight Hem (for sheers only)
Mike's Tip!
Overlocked hems help to reduce flaring at the bottom of blockout curtains for a cleaner fall.
7
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
Minimum and Maximum Sizes
Width:
Min: 600mm
Max: 10,000mm (hand drawn)
Max: 5000mm (motorised)
Drop:
Min: 500mm
Max: 2900mm – 6000mm (check fabric specs)
You’re Ready to Order
