Ordering custom curtains online has revolutionized home design. It allows you to access luxury fabrics and tailored fits without the markup of a designer showroom. However, the fear of making a mistake—resulting in non-returnable drapes that don't fit—is real.
We have helped thousands of customers transform their homes, and we often see the same errors popping up. The good news? They are entirely preventable. Here is your guide to avoiding the pitfalls and getting that professional, showroom look on the first try.
Mistake #1: The "One-Measure-Fits-All" Trap (Height Accuracy)
The most frequent issue we see is curtains that arrive slightly too short (creating light leaks) or too long (dragging awkwardly). The root cause usually isn't the tape measure; it's where you start measuring from.
Many homeowners assume you always measure from the rod. This is incorrect. The measurement point changes depending on the header style:

- For Rod Pockets or Grommets: You must measure from the top of the curtain rod to your desired ending point (usually the floor).
- For Pleated Styles (Pinch Pleat, Pencil Pleat): These are hung using rings and hooks. You must measure from the bottom of the ring eyelet (where the hook inserts) to the floor.
⚠️ Pro Tip: If you measure from the top of the rod for a pleated curtain, your drapes will arrive too long, ruining the look.
Mistake #2: Ignoring the "Stacking" Width

When ordering custom window treatments, many people order the exact width of their window frame. This results in curtains that look flat when closed.
- The Fix: You need to account for "fullness." For a luxurious, gathered look, your total curtain width should be 1.5x to 2.5x the width of your curtain rod or track.
Mistake #3: Choosing the Wrong Header Style for Usage
Headers aren't just cosmetic; they dictate how the curtain functions.

- Rod Pocket are beautiful but difficult to slide. They are best for decorative panels that you rarely close.
- Pinch Pleat or French Pleat glides effortlessly on rings or tracks. If you plan to open and close your curtains daily (like in a bedroom), opt for a pleated style for smooth operation.
Mistake #4: Hanging the Rod Too Low
A common instinct is to install the rod directly above the window frame. However, interior designers agree that this makes the room feel smaller.
- The Golden Rule: Install your hardware high and wide. Place your rod 4–6 inches above the window frame (or even up to the ceiling molding) to draw the eye upward. For more on this, read Better Homes & Gardens' guide on The Dos and Don'ts of Hanging Curtains.
Mistake #5: Forgetting the Lining

Fabric looks different when light shines through it. Without a lining, even a dark fabric can look washed out during the day.
- Privacy: Standard lining protects your furniture from UV rays.
- Sleep: For bedrooms, always upgrade to blackout lining to ensure 100% light control.
Conclusion
Getting custom curtains right is about precision, but it doesn’t have to be stressful. By double-checking your measuring points based on your chosen header style, you guarantee a perfect fit that elevates your entire room.
