How to Measure a Window for Net Curtains

How to Measure a Window for Net Curtains begins with a clear first measurement and a plan. This guide gives direct, practical steps so readers get an accurate width and drop every time. It explains when to use a recess fit versus a face fit, how much extra fabric to allow for gather, and where to position the rod or track. The instructions assume a steel tape, notepad, and a stool for high sills. By following the simple checks here, people avoid the common mistakes that lead to returns or remakes.

Tools You’ll Need Before You Start

Start with the key fact: use a steel tape, a notepad and a step stool for high windows. A steel tape gives true measurements: cloth tapes can stretch and mislead. They will need:

• Steel tape measure (at least 3 m)
• Notepad and pen for three recorded measurements
• Step stool or small ladder for high reveals
• Existing rod/track measurements if replacing curtains

A practical tip: hold the tape securely against the frame lip with one finger while recording the number to avoid a slanted read. When measuring deep reveals, put the tape flush against the inner wall and snap the end firmly so the tape’s zero point is exact. If the homeowner has an existing wire or rod, measure its visible length and note mounting brackets, this saves time when ordering a new net.

Common mistake: writing down a measurement without noting units. Always mark cm or inches beside each number. If three measurements differ, always use the smallest width and the longest drop (see later sections for why).

Measuring Width — Recess Vs Face Fit (Which To Use And Why)

Key answer: choose recess fit when the net will sit inside the window frame: choose face fit when the net must overlap the frame or hide uneven edges. Recess fit gives a neat look and keeps nets close to the glass. Face fit covers imperfections and creates more light-blocking overlap.

Recess fit suits tidy sash windows and modern frames. It requires precise inside-frame measurements because the net must pass into the reveal without catching. Face fit suits older or irregular frames, or when a fuller appearance is wanted. Install the track above the architrave and add overlap so nets clear the glass when stacked.

Practical decision rule: if the reveal is at least 3 cm deep and straight, use recess fit. If the reveal is shallow, warped, or the homeowner wants more privacy, choose face fit and allow overlap. A linked primer on window treatments shows common set-ups and can help choose style.

Recess Width: Step-By-Step Measurement Method

Fact first: measure inside the recess at three points and use the smallest reading. This prevents a tight fit that won’t slide into the narrowest spot.

Step-by-step:

1. Place the steel tape flat against the left inner wall at the top of the recess and extend to the right inner wall. Record that number.
2. Repeat at the middle (mid-height) and at the sill or bottom reveal.
3. Compare the three figures and write down the smallest width as the recess width.

Why the smallest? Frames can twist or bulge: a net must fit the narrowest section to install smoothly. For ordering the finished net or track, use this recess width as the track length. Then multiply the track width by 2–2.5 to estimate fabric width needed for standard gather (2× gives moderate fullness: 2.5× gives a fuller look). Example: a 120 cm recess track will typically need 240–300 cm of fabric.

A cautionary story: a fitter once measured only the centre of a bowed reveal and ordered nets 3 cm too wide: the nets jammed on the top corner. Measuring three points avoids that frustration.

Face-Fit Width: Overlap, Track Placement And Allowances

Direct answer: for face fit, measure the full frame width and add 5–10 cm on each side for nets: add 15–30 cm each side for heavier curtains. Track placement is typically 12–15 cm above the top of the reveal or fixed above the architrave.

How to measure:

1. Measure the outermost visible width of the window frame (end to end).
2. Add 5–10 cm per side for net curtains that need to clear the glass and stack neatly when open. If the homeowner wants full coverage and thicker stacking, add 15–30 cm per side.
3. Decide track position: place it 12–15 cm above the recess to allow the net to hang naturally and avoid hitting the sill when open.

Example: a 100 cm frame plus 10 cm each side yields a track width of 120 cm. If a heavier curtain is paired behind the net, those wider overlaps prevent light gaps when drawn. Also note that face-fit installations can hide uneven architraves: order a slightly wider net to ensure continuous coverage.

Measuring Drop (Length) For Different Hanging Styles

Short answer: measure from the rod or track top to the desired finish: take three vertical readings and use the longest. Drop differs by style, recess, face fit, café nets, so pick the method first.

Recess fit drop: measure from where the track will sit at the top inside the reveal down to the sill or desired end point. Take measurements at left, centre and right: use the longest to avoid the net pulling short on one side. Add about 1 cm if the wire sits inside a groove so the net just covers the wire.

Face fit drop: measure from the fixed rod/track position (often 12–15 cm above the frame) down to the sill or just below the sill if a puddle look is wanted. For nets that end at the sill, subtract 1–2 cm if the homeowner wants them slightly off the sill to avoid wear.

Café nets: measure from the rod to mid-window or to the desired mid-height mark. Café nets often stop at the handle height: take care to avoid interfering with window hardware.

A practical warning: do not assume symmetry. Older houses often have sills that slope: the longest measurement ensures a confident fit. For pairing nets with blackout liners, measure the outermost curtain drop too so both hang level together.

Final Checklist, Common Mistakes To Avoid, And Measurement Notes For Ordering

Immediate checklist: measure width three times, measure drop three times, note units, record whether fit is recess or face, and note existing rod/bracket positions. These facts ensure the order matches reality.

Common mistakes:

• Mixing cm and inches on the same order (always convert and label).
• Using glass size instead of recess or track size, glass is rarely the correct guide.
• Forgetting gather allowance for nets (order fabric 2–2.5× the track width).
• Omitting the mounting height for face fit tracks (12–15 cm matters).

Ordering notes: when placing an order, state whether the measurement is recess or face-fit and include the bracket projection if known. If replacing an existing wire, measure the visible wire length and the distance from the mount to the wall: include these in the notes to the fitter.

Conclusion

Measuring correctly means measuring three times, choosing recess or face fit deliberately, and adding the right allowances for overlap and gather. With a steel tape, clear notes, and these steps, the net will fit and hang as intended. If unsure, order a slightly larger fabric width for ease of alteration and consult the full site guide before final purchase.
