Net curtains are a good way to ensure privacy from passersby and add a finishing touch to windows. Measurements for net curtains, or indeed any curtain, should only be taken once the fixtures and fittings for the curtains are in place, as different fixtures sit at slightly different heights. Normally the fixtures for a net curtain will be on the inside of recessed windows, and they will be less sturdy as they have less weight to hold. The style and fullness of the curtains also has an impact of the size of curtain needed, and should be considered before starting to measure.
Draw a rough diagram of the window you want to measure. If you want floor-length curtains, include a line below the drawing of the window to represent the floor.
Measure the width of the hanging rod, rail or cord, not including any decorative ends of curtain rods. Note this measurement at the top of your drawing.
Carefully standing on the stepladder or chair, measure the length of the window from the curtain fixture to the windowsill. If you want floor-length curtains, measure from the fixture to the floor. Note this measurement at the side of your drawing.
If you want curtains to be full (have excess material so they don't hang in a flat sheet) multiply the first measurement you took (the width) by 3. For example, full net curtains on a 60 cm (2 foot) fixture would measure 1.8 m (6 feet) when flat.
If you are making your own curtains, add allowances to these measurements for hems on both sides, and seams if your window is wide enough to need more than one width of net. Heavier weight curtains need less fullness; for medium weight materials such as cotton, the width of the hanging space should be multiplied by two or two and a half.
Climbing up ladders or on chairs can cause accidents. If you are unsteady on your feet, or at all unsure about this activity, get a friend to help you measure the length of your window.
