Curtain Measuring Guide

Get the Perfect Fit Every Time

Measuring for curtains doesn’t have to be complicated. Just follow our simple step-by-step guide to ensure a professional, made-to-measure finish.


🪟 Step 1: Decide Where You Want to Hang Your Curtains

Option A: Above the Window Frame

  • For a more dramatic look and to make the window appear taller, fit the pole or track 15–20cm (6–8 inches) above the window.

Option B: Inside the Recess

  • Ideal for a neat, flush look. Only use this option if you're not concerned about blocking out all light.


📏 Step 2: Measure the Width

If Using a Curtain Pole:

  • Measure the full width of the pole (excluding decorative finials).

  • For gather fullness, multiply the pole width by:

    • 1.5x for a standard gather

    • 2x for a fuller, more luxurious look

If Using a Curtain Track:

  • Measure the full width of the track from end to end.


📐 Step 3: Measure the Drop (Height)

Your drop measurement depends on how you want your curtains to fall:

Heading Styles:

  • Pencil Pleat / Eyelet / Tab Top:

    • Measure from the top of the pole or track to where you want the curtain to end.

    • Standard drop lengths: Sill, Below Sill, or Floor Length.

Style Drop Point
Sill length 1 cm above the windowsill
Below sill 15–20 cm below the windowsill
Floor length 1 cm above the floor (or longer for pooling)

For eyelet curtains, measure from the top of the pole and add 2.5cm to account for the eyelet position.


🔧 Top Tip:

  • Always use a metal tape measure for accuracy.

  • Double-check each measurement twice.

  • Make a note of any obstructions (radiators, handles, skirting) that may affect the curtain drop.
