How to measure up for a curved bay window pole

We want to get it right…

Please read: By default, these poles are for bay windows with smooth continously curved walls of constant radius. If your bay has straight wall sections at the mouth of the bay please measure per “Curve with flat ends” , or as a multi-angle bay if appropriate, as below…


Along the face of the curved wall
Measure in millimetres from A to C =
Depth of the Bay
Measure in millimetres from B to D =
Across the front
Measure in millimetres from A to C =


Along the Return walls too?

If you’d like the pole to continue around the return walls please also measure:

Measure in millimetres from 1 to A =
Measure in millimetres from 2 to C =

Along the face of the curved wall
Measure in millimetres from A to C =
Depth of the curved part of Bay
Measure in millimetres from B to D =
Across the front of curve
Measure in millimetres from A to C =
Side Walls
Measure in millimetres from A to E =
Measure in millimetres from C to F =
(If the walls  are not parallel (i.e. splay out) also measure the diagonals A to F and  E to C as well as E to F)

Along the Return walls too?

Measure in millimetres from 1 to E =
Measure in millimetres from 2 to F =


•Take measurements along the wall at pole fixing height, above the window, where the brackets are to be fixed (even for ceiling fix poles).
•If necessary state the distance you’d like between the wall and the pole (the default is 45mm (16mm dia), 50mm (25mm dia))
•If necessary state where you’d like the finial to end (the default is the mouth of the bay). The poles can have return bends too.
•Measure in millimetres as errors can accumulate
** Use a  metal tape measure, held taut for the straight lengths.
** Use a fabric or fibre-glass tape flat along the face of the curved wall.

You’ll need someone to give you a hand especially for the curve depth B to D length. Please be as accurate as possible here as a small error can make a big difference.

We can make a pole fit with remarkably little space for brackets but please let us know if there are any potential issues.

Notice how a curved pole of constant radius varies in distance from the wall, being greatest at the wall angles (vertices). In this situation it’s often better to fix the pole to the ceiling to avoid varying wall fix bracket projections.

For an angled bay with a curved pole, you should measure the diagonals and walls of the bay window.


How much will it cost?
