Consider using a sunscreen blind inside the window frame for daytime privacy and light control.

Roman blind Stack height

Stack Height

If you want to raise your roman blind above the window frame to maximise your view, the stack height of a roman blind is approximately 300mm.

Take this into consideration when measuring your drop.

Roman Blinds head rail

Head Rail

A fresh and contemporary design, the Acmeda ‘No Sew Headrail’ features a slim square profile design, which moves the fabric up to hide the brackets and then cascades down for a clean modern look.  Easily installed, this blind system ensures smooth, quiet movement with the strength to manage fabrics of any weight - small or large.

Bottom Rail

All Roman blinds come with a fabric covered tear drop bottom rail.  This beautiful bottom rail is designed to be aesthetically pleasing from both the front and back.

Roman Blind Back Batterns

Back Battens

Our roman blinds are cleverly designed with a smooth and slimline back batten system, which simply slides over the fabric - meaning no stitch holes, no puckering and no light penetration resulting in a neater and refined look.  Each batten comes with a colour matched end cap.

Choose from metal, black, white or stainless steel.

Stainless steel is recommended if you live near the coast.

Michael's Tips

  • Always measure in millimetres (mm)
  • Always use a steel tape measurer or a laser measurer for accuracy - make sure the tape measure is straight and tight when you take your measurements.  
  • Measure all windows, even those that appear to be the same width and height
  • Add your room name to each of your blinds as you order them.
  • Do not take any deductions 
  • Measure at the top of the window frame where the blind is to be installed.  This is where your brackets will be placed.
  • If you live near the coast, order your blinds with stainless steel chains.
