How to Measure for Curtains

Accurate measurements are crucial to ensure your curtains fit perfectly, hang beautifully, and function smoothly. Follow this step‑by‑step guide:


1. Decide on Mounting Type

  • Wall/Pelmet Mount (Outside Recess): Curtains sit outside the window frame, covering more wall area for better light‑block and visual height.

  • Inside Recess Mount: Curtains hang within the window frame for a streamlined look; best for windows without obstructions.


2. Gather Your Tools

  • Metal Tape Measure: Avoid fabric or plastic tapes for precise readings.

  • Notebook & Pencil: Record each measurement immediately.

  • Stepladder or Stool: To reach high tracks or pelmets safely.

  • Spirit Level (Optional): Ensure your rod or track will hang straight.


3. Measuring Width

  1. For Pole or Track (Outside Recess):

    • Measure the total span from outer edge of where the bracket will sit on one side to the other.

    • Add 10–15 cm on each side to allow the curtains to stack back fully and block light.

    • Example: A 120 cm‑wide window → 120 cm + (2 × 15 cm) = 150 cm pole/track length.

  2. For Inside Recess:

    • Measure the exact width between the recess walls at three points (top, middle, bottom).

    • Use the smallest measurement to ensure smooth operation without rubbing.


4. Measuring Drop (Curtain Length)

  1. Wall/Pelmet Mount:

    • Determine where your rod or track will sit (just above the window frame or at ceiling level).

    • Measure from that point down to where you want the curtains to finish:

      • Sill Length: 1 cm above the sill.

      • Floor Length: 1 cm above the floor.

      • Puddled Style: Add extra (e.g., 5–10 cm) for a gentle pool.

  2. Inside Recess:

    • Measure from the top inside edge of the recess down to the sill or floor (minus 1 cm to avoid dragging).


5. Determine Fullness

Fullness = how “rich” or gathered your curtains appear. Multiply your pole/track width by the fullness ratio:

Curtain Type Fullness Ratio
Sheers & lightweight fabrics 1.5×
Standard drapes
Pinch/Goblet pleats & luxury 2.5–3×

Tip: Fabric requirements = (Pole/track width) × (Chosen fullness ratio).


6. Note Heading Style & Hardware

Different headings need different fittings:

  • Pencil Pleat & Wave Pleat: Use track systems—measure track length and carrier spacing.

  • Eyelet & Tab Top: Use poles—ensure pole diameter matches eyelet/tab size.

  • Pinch/Goblet Pleats: Use rings and hooks on rods or gliders on tracks—measure the distance from rod to curtain top accordingly.

7. Record & Double‑Check

  • Write down three width measurements (top, middle, bottom) for recess mounts.

  • Verify your drop measurement at both sides of the window.

  • Confirm your pole/track length and bracket positions before ordering.
