How to measure

Roller shades

Send us the opening, not the shade. We apply the deductions, so every figure below is the raw measurement taken at the window.

Width first, then drop. Always to the nearest 1/8 inch. Never deduct anything.

Before you start

  • Decide the mount: inside the frame, or outside on the wall.
  • Check the frame depth. An inside mount needs enough room for the bracket and the roll.
  • Decide the control: cordless, chain, wand or motorized.
  • Have a steel tape. A cloth tape stretches and a phone app is not accurate enough.

01

Choose the mount

An inside mount sits within the frame for a clean line and takes up no wall space. It needs enough frame depth for the roll and brackets, measured in the next step, and it leaves a small light gap at each side that a channel closes if the client wants full darkness.

An outside mount covers the opening and is the better answer for blackout, for a shallow frame, or where something in the recess gets in the way.

Inside the frame
Outside the frame, overlapping each side

02

Measure the frame depth

Inside mount only

An inside mount only works if the frame is deep enough to hold the roll and the brackets. Measure from the face of the frame back to the glass, at the top where the shade will sit, and check it against the depth the chosen top treatment needs.

Depth requirements differ by top treatment: an open roll needs least, a cassette most. On Meridian, for example, an arc cassette needs more than 3 1/4" for the small and more than 4" for the large. [Confirm the Skyfall figures against the specification table before this goes live.] Not enough depth means an outside mount, or a shallower top treatment.

03

Measure the width

Inside mount: measure across the opening at the top, the middle and the bottom. Send the narrowest of the three. Openings are rarely square and the shade has to clear the tightest point.

Outside mount: measure the area to be covered, overlapping the opening by at least 1 1/2 inches each side, so 3 inches in total.

04

Measure the drop

Inside mount: measure at the left, the centre and the right, and send the shortest. Outside mount: measure from where the top of the shade will sit down to where it should finish, usually the sill or a set distance below it.

Drop at the left, centre and right

05

Check for obstructions

Handles, cranks, alarm sensors, a deep sill or tile return. Anything in the path changes the mount or the roll direction, and it is the most common reason a correctly measured shade will not fit.

Check what the shade has to clear

06

Pick the roll direction

Standard roll brings the fabric down the back of the tube, closest to the glass, for maximum coverage and the least light at the edges. It is the default.

Reverse roll brings the fabric down the front, away from the glass. Use it to clear a handle, a crank or a deep sill, and remember it only works with two of the six top treatments.

Standard roll, fabric to the rear
Reverse roll, fabric to the front

07

Set the control side

Standing in the room facing the window, say which side the chain or wand sits. On a run of shades keep them consistent unless the client asks otherwise, and check nothing blocks the control at that end.

Control on the left or the right

08

Label every window

Name each opening by room, and number them where a room has several. Start at the front door and work clockwise. It costs a minute on site and saves an hour when the order and the install both refer to the same window.

Label every opening by room

Chain lengths

A chain drive ships with the chain cut to suit the drop, so there is nothing to specify on the order. The lengths supplied:

Up to 48"
[TO CONFIRM]
48" to 72"
[TO CONFIRM]
72" to 96"
[TO CONFIRM]
96" and over
[TO CONFIRM]

A chain that reaches the floor is a safety failure, so tell us if a window needs a shorter chain than the drop suggests.

Motor options

Every motorized collection uses the Apollo range, so one remote or hub runs the whole house whatever mix of products is specified.

Hardware and finishes

Bottom rail finishes

Bottom rail

A flat profile as standard, in [TO CONFIRM] finishes. Fabric wrapped is available, and matching the bottom rail to the top treatment is what makes a run of windows read as one job.

Bracket color to suit the frame

Bracket color

White or black as standard. White disappears against a painted reveal, black suits a dark frame or a deliberate contrast. Covered entirely by a cassette or fascia, so this only matters on an open roll.

Top treatments

Open roll, arc cassette, square cassette, metal fascia, fabric-wrapped cornice or raceway. The full detail is on the Skyfall page; what matters when measuring is that a cassette needs more depth than an open roll.

Openings wider than one shade

A single shade runs to [TO CONFIRM] wide. Past that, the opening takes two or more shades. They can share a cassette so the window reads as one treatment, or sit as separate shades with their own controls.

  • Two or more shades under a single cassette, up to [TO CONFIRM] overall
  • Independent controls at each end, or one control if they are on a shared tube
  • A slim light line where the shades meet, which a client should be told about before it is quoted

Putting the order together

With the windows measured and labelled, the order takes a few minutes in the portal.

  1. Pick the collection, fabric and color
  2. Enter width and drop for each window, in inches to the nearest 1/8
  3. Choose the control type and the side it sits on
  4. Choose the roll direction and the top treatment
  5. Add the room name you labelled the window with
  6. Check the summary against your schedule before submitting

What causes remakes

  • Width and drop entered the wrong way round. Width is left to right, always first.
  • Deducting for the brackets. We do that. Send the opening.
  • One measurement taken for a run of windows that look identical.
  • Rounding up. Round down to the nearest 1/8 inch.
  • Measuring an inside mount without checking the frame depth, then finding the cassette will not fit.
  • Recording in a mix of inches and decimals.

Where the sizes stop

Full specification tables are in the Skyfall guide, which approved dealers receive. The headline limits:

Maximum fabric width
Up to 110", depending on the fabric
Inside mount deduction
Applied at the factory, not by you
Reverse roll
Available with two top treatments
Raceway
Cordless open roll only

Not sure on a window?

Send the measurements to your dealer success manager before you order. A five minute check beats a remake.
