How to Measure for Curtains: A Step-by-Step Guide for Irish Homeowners
One of the most common questions we hear from customers visiting our Dublin showroom is, How do I make sure I measure my windows correctly?
Ordering bespoke made to measure curtains is an investment. The good news is that measuring your windows is actually quite simple once you understand the basics.
Whether you live in a modern apartment in Dublin, a new detached home in Kildare or a traditional cottage in the countryside, accurate measurements ensure your curtains hang beautifully and function properly.
Follow this simple step by step guide to measure your curtain correctly.
Why Correct Curtain Measurements Matter
Curtains that are too short or too narrow can completely change the look of a room.
Incorrect measurements can lead to:
- Curtains that do not fully cover the window
- Gaps where light enters the room
- Curtains that look awkward or unfinished
- Fabric dragging excessively on the floor
Taking accurate measurements ensures your curtains fit perfectly and create a polished interior look.
Step 1: Install Your Curtain Hardware First
Before you start measuring, make sure your curtain pole or track is installed.
Many homeowners make the mistake of measuring only the window frame. Curtains actually hang from the pole or track, so that is what you need to measure.
If you have not installed your curtain hardware yet, a good rule of thumb is to extend the curtain pole or track 15 to 20 cm beyond each side of the window frame.
This allows the curtains to stack neatly to the side when open and ensures the window is not blocked by fabric.
Mounting the pole slightly higher than the window frame can also make the room appear taller.
Step 2: Measuring the Curtain Width
The width measurement depends on whether you are using a curtain track or a curtain pole.
Measuring for a Curtain Track
Measure the full length of the track from one end to the other.
This measurement represents the full width your curtains need to cover.
Measuring for a Curtain Pole
Measure the pole between the decorative end pieces, also called finials.
Do not include the finials in your measurement, as the curtain fabric will not extend over them.
Once you provide this measurement, your curtain maker will calculate the correct amount of fabric needed to create the desired fullness and folds.
Step 3: Determining the Curtain Drop (Length)
The drop refers to the length of the curtain from the top of the pole or track to the bottom of the curtain. There are several common curtain lengths used in Irish homes.
Sill Length Curtains
These curtains finish just above the windowsill.
Standard measurement:
1 to 1.5 cm above the sill
This style works well for kitchens, bathrooms and small windows.
Below Sill Curtains
These curtains fall slightly below the windowsill.
Standard measurement:
15 cm below the sill
This option is often chosen for practical reasons as it helps block cold drafts coming through the window.
Floor Length Curtains
Floor length curtains are the most popular choice in modern homes.
Standard measurement:
1 to 1.5 cm above the floor
This creates a clean and elegant appearance.
Puddled Curtains
For a more dramatic and luxurious look, some homeowners prefer curtains that extend slightly onto the floor.
Standard measurement:
5 cm longer than the floor
This creates a soft puddling effect.
Measuring for Different Curtain Styles
Different curtain styles may require slightly different measurements.
Eyelet Curtains
Measure from the top of the curtain pole to where you want the curtain to finish.
Because the eyelet ring sits on the pole, this measurement determines the final drop.
Pinch Pleat Curtains
For pinch pleat curtains, measure from the top of the curtain track to the desired curtain length.
The hooks will attach directly to the track.
S Fold Curtains
For S Fold or wave curtains, measure the total width of the curtain track and the drop from the track to the desired curtain length.
These curtains require a specialised wave track system.
How to Measure for Bay Windows
Bay windows are very common in Irish homes, especially in older Dublin properties.
Measuring bay windows can seem complicated, but it becomes easier if you break it down.
Measure each section of the bay window individually and record the measurements separately.
If you are installing a curved track, measure the full length of the track once installed.
For professional results it is recommended measuring bay windows twice to ensure accuracy.
Common Curtain Measuring Mistakes
Many measuring mistakes happen because homeowners rush the process.
Here are a few common mistakes to avoid.
Measuring Only the Window Frame
Always measure the curtain pole or track, not just the window.
Forgetting the Finials
When measuring a pole, exclude the decorative ends.
Choosing Curtains That Are Too Short
Curtains that are too short can make a room look unfinished. Floor length curtains generally create a more elegant appearance.
Not Checking Measurements Twice
Even a small measurement error can result in curtains that do not fit properly.
The Golden Rule of Measuring Curtains
Always use a metal tape measure.
Fabric or plastic measuring tapes can stretch over long distances, which may result in curtains being slightly too short.
A metal tape measure ensures accurate measurements and avoids costly mistakes.
It is also a good idea to measure twice before ordering your curtains.
Final Thoughts
Measuring for curtains may seem intimidating at first, but once you understand the process it becomes straightforward.
Taking a few extra minutes to measure carefully ensures your curtains fit perfectly and enhance the overall look of your home.
