Accurate Curtain Measurements for apex and shaped windows
Measuring curtains for apex, triangular and architectural windows is very different from standard windows. Angles, height and proportions all play a role in how the final curtains will look and operate.
A small measuring mistake on a shaped window can affect the entire result. This is why accurate, on-site measurement is one of the most important parts of the process.
Why apex windows are harder to measure
Apex and triangular windows introduce angles that standard curtain measuring guides do not account for. The top point, sloping sides and varying wall heights all need to be considered together.
- Sloping ceilings and angled walls
- Uneven heights across the window
- Track positioning and fixing points
- How the curtains will stack when open
What we measure during a home visit
During a professional consultation, we take multiple measurements to build a complete understanding of the window and surrounding space.
Width
Full span of the window and beyond, including stack-back space.
Drop
Multiple drop points are taken due to angled ceilings.
Apex height
The highest central point of the window.
Track position
Where the curtain track will be fixed for best visual result.
Why DIY measurements often fail
Measuring shaped windows without experience can lead to incorrect proportions, poor curtain flow and installation issues.
Common issues include curtains sitting unevenly, incorrect stacking, or tracks being positioned in the wrong place.
The difference professional measuring makes
Accurate measuring ensures that the curtain design works with the architecture of the window, rather than against it.
- Balanced proportions across the window
- Correct curtain fullness and drape
- Smooth operation on angled tracks
- A cleaner, more considered final finish
Get your windows measured properly
If you have an apex or shaped window, the best results start with accurate measurements taken on site.
