Why Accurate Curtain Measurements Matter
Correct measurements ensure curtains hang properly and look intentional. Even small errors can result in curtains that feel awkward or unfinished.
What You Need Before You Start
You’ll need a metal tape measure, a notepad, and clarity on whether your curtains will hang from a pole or a track.
How to Measure Curtain Width
Always measure the curtain pole or track, not the window itself. Curtains should typically be 1.5 to 2 times the width of the pole to achieve a full, gathered look.
How to Measure Curtain Drop
Measure from the top of the pole or track down to where you want the curtains to finish. Popular options include sill length, below sill, and floor length.
Common Measuring Mistakes
Measuring the window instead of the pole, forgetting about fullness, and rounding measurements too aggressively are all common issues.
UK Curtain Sizing Explained
Ready-made curtains are available in standard drops. Choosing the closest size above your measurement usually gives the best result.
Final Tips Before Ordering
Measure twice, order once. When in doubt, slightly longer curtains are easier to adjust than ones that are too short.
