Curtain pole measurement guide.
Our 28mm metal bay window curtain pole kits offer two size options.
Getting the right measurements for your curtains is easy just follow our step by step guide.
A grommet that is 1 4 inch larger than the rod diameter slides smoothly along the rod.
Measure the width of the rod from left to right.
It s large enough to allow for.
Measure the length of the pole between the finials decorative ends.
Have a steel tape measure ready and something to write all of your measurements down as you go along.
For ready made curtains the width of the pole track wants to be roughly the same size as one curtain.
When a pole width falls in between the standard size widths 46 66 or 90 it depends on how full the curtains need to be.
A common rule for displaying curtains properly says the curtains finished width should be at least 2 times the width of your window if not more sheers can be 3 times the window width to achieve a look of proper fullness.
