?How To Measure Pelmets & Valances
General Information
Taking potential light constraints into consideration, a valance or pelmet should measure to approximately 1/6th of the finished curtain length
The pelmet shelf must be fitted before the measurements are taken
Measuring the Length
To determine the length, divide the curtain length by six.
eg, if your finished curtain length is 150cm, the pelmet or valance should measure 25cm.
To determine the length for a shaped pelmet or valance, the measurement is taken from the top of the pelmet board to the midpoint of the arch. The sides of the pelmet or valance will then be made 20cm longer
eg, if your finished curtain length is 150cm, the pelmet or valance at the top of the arch will measure 25cm and the sides 45cm
Measuring the Width
To calculate the pelmet & valance width
measure the distance from the wall (a
along the front of the pelmet (b
and back to the wall again (c
Width of pelmet (cm) = a + b + c
