# How to measure a continuous curve bay…

*Curved Bay Window Curtain Pole.*

Also known as *Bow Window or Round Bay.*

*We want to get it right…*

*Please read carefully:* *By default, **these poles are for bay windows with smooth continuously curved walls of constant radius (i.e. a simple curve). If your bay also 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, shown at the bottom of the page. These poles may require compound elememts of simple curves and straight sections combined to achieve the best fit.
*

* 25mm diameter tube is best for curves!*

**Please could you also send a photo of your bay window 🙂**

**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 the measurements along the walls** where the pole is to fix and include the full length of each wall section** (even for ceiling fix poles). We will work out the pole size to fit allowing for bracket projection from these measurements.**

•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.

**For your sake and ours you must take the time to provide careful and accurate measurements. We won’t make bay poles unless we are confident they will fit!**

*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.*

For an angled bay with a curved pole, you should **measure the ****diagonals and walls** of the bay window. Please refer to the relevant measuring guide for other multi-angle bays e.g. Six Bend Bay

*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. *
