How Do You Measure Curtains for a Perfect Fit?

Ever stood back to admire your newly hung curtains only to find they look oddly proportioned? Too short, too narrow, or simply not quite right? The perfect curtains transform a room, but achieving that polished look requires precise measurements. At Softhome, we've helped countless homeowners achieve that perfect fit, and today I'm sharing our expertise with you.

Why Proper Curtain Measurements Matter

Properly measured curtains do more than just cover your windows. They create visual harmony in your space, enhance privacy, and can even improve energy efficiency. Ill-fitting curtains, on the other hand, can make even premium fabrics look awkward and unprofessional.


Taking accurate measurements is the foundation of beautiful window treatments. It's a small investment of time that yields significant aesthetic returns. Let's walk through the process step by step.

Essential Tools for Measuring Your Curtains

Before you begin, gather these simple tools:

  • Metal tape measure (not fabric, which can stretch and give inaccurate readings)

  • Step ladder for reaching higher points

  • Notepad and pen for recording measurements

  • Pencil for marking installation points

A metal tape measure is crucial for accuracy. Fabric measuring tapes can stretch over time, leading to measurements that are off by several centimetres.

However the best is to equip yourself with a digital laser range finder measuring tool.

How to Measure Curtain Width Correctly

The width measurement determines how much fabric you'll need and affects how your curtains will hang when closed.

For Existing Curtain Rods or Tracks

If you already have curtain hardware installed:

  1. Measure the entire length of your curtain rod or track from end to end

  2. For decorative rods with finials (those ornamental ends), measure only the usable portion of the rod, excluding the finials

  3. If your track has an overlap in the centre, add this to your measurement

For New Installations

If you're starting from scratch:

  1. Measure the width of your window frame

  2. Add at least 15-20cm to each side (30-40cm total) to allow curtains to cover the window completely when closed

  3. This extended measurement will be your ideal rod or track width

For optimal light blocking and a more luxurious look, consider adding even more width—up to 30cm on each side for larger windows.

Determining the Perfect Curtain Length

The length or "drop" of your curtains significantly impacts the overall appearance of your window treatment.

Where to Start Your Measurement

The starting point for your length measurement depends on your curtain type:


For Double pleat Pleat Curtains:

  • On a track: Measure from the top of the track

  • On a pole: Measure from the underside of the pole, ignoring the rings

For Eyelet Curtains:

  • Measure from the top of the pole

  • Note that eyelet curtains work best with poles up to 29mm in diameter

Where Your Curtains Should End

You have several stylish options for where your curtains should finish:


Sill Length:

  • Measure to just touching the windowsill

  • Creates a clean, tailored look perfect for kitchens and bathrooms

Below Sill:

  • Measure to 15-20cm below the windowsill

Floor Length:

  • Measure to just touching the floor

  • Creates an elegant, formal appearance

Pooling on the Floor:

  • Add 5cm for a luxurious puddle effect

  • Best for stationary panels that won't be opened and closed frequently

Always take multiple measurements across your window span, as floors and windowsills aren't always perfectly level. Use the shortest measurement to ensure your curtains don't drag on the floor.

Calculating Curtain Fullness for a Luxurious Look

Fullness refers to how much fabric is used relative to your window width. This single factor dramatically affects how professional your curtains look.


For a luxurious, full appearance, your curtain width should be 2 times the width of your window or rod. This fullness factor ensures proper draping and a professional look.


For example:

  • If your rod measures 200cm, your curtains should have a total width of 400cm

  • This might mean purchasing two panels of appropriate width

Common Measuring Mistakes to Avoid

Even experienced decorators can make these measuring errors:

  1. Measuring only the window instead of the rod or track

  2. Forgetting to account for fullness

  3. Not considering radiators, furniture, or other obstructions

  4. Taking only one measurement (floors and ceilings aren't always level)

Take your time with measurements. A single mistake can result in curtains that never look quite right!

Special Considerations for Different Window Types

Bay Windows

For bay windows, you have two options:

  1. Treat each section as a separate window and measure individually

  2. Use a flexible or custom-bent rod that follows the window's contour

Take measurements for each section of the bay window from the outermost edge of each frame.

Sliding Glass Doors

For sliding doors:

  1. Measure the width of the doorframe

  2. Account for any hardware like handles that might extend beyond the frame

  3. Consider adding extra width for better coverage when closed
