In our homes, windows are more than just openings—they are the soul of a room’s narrative. Whether you’ve chosen our Elise Heavyweight blackout drapes or our signature Lorna Linen, achieving that refined, high-end look comes down to one thing: the perfect fit.
If you are ready to elevate your space, this guide will show you exactly how to measure for curtains to achieve that effortless, designer-level drape we all strive for.
1. The Pro’s Tool: Trust Your Steel Tape
Before we begin, put away the fabric sewing tape. For a true bespoke fit, always use a metal steel tape measure. Fabric tapes can stretch or sag over time, and in custom window treatments, a fraction of an inch is the difference between "just right" and "just off."

2. The "High & Wide" Strategy
To capture that timeless Transitional or Classic American aesthetic, we always recommend mounting your hardware higher and wider than the window itself.
- The Wide Look: Extend your curtain rod 6 to 10 inches beyond the frame on each side. It makes your windows feel grander and floods the room with light.
- The High Look: Mount your rod 4 to 6 inches above the trim—or even halfway to the ceiling—to create an airier, more expansive atmosphere.
3. Calculating Width: Fullness & Formulas
In the world of custom drapery, the most common mistake is skimping on fabric. To ensure your curtains maintain a rich, textured look rather than looking like a flat sheet when closed, you must choose the right "Fullness" based on your hanging style:
A. Tailored Pleats (e.g., Pinch Pleat, Tailored Box Pleat)
These curtains are sewn with permanent pleats. They come with a default 2.0x fullness built into the craftsmanship.
-
The Formula:
Panel Width = (Rod or Track Length) / Number of Panels - Pro Tip: Since the pleats are fixed, you only need to provide the exact length of your rod. We handle the complex fabric math to ensure the perfect drape.If you desire a fuller visual effect, simply add extra width to this calculated result.
B. Flat Panels (e.g., Rod Pocket, Flat Hooks)
These panels create natural folds through hanging. You can choose your desired aesthetic by adjusting the multiplier:
- 1.6x (Minimalist): Clean and subtle, perfect for modern, airy spaces.
- 2.0x (Classic): The gold standard for American homes, offering a balanced, rhythmic fold.
- 2.5x (Luxury): Ideal for our Elise Heavyweight collection to create an indulgent, high-end silhouette.
-
The Formula:
Panel Width = (Rod Length × Fullness Multiplier) / Number of Panels
4. Choosing Your Length: Three Signature Silhouettes
- The Float: Stopping 1/2 inch above the floor. Clean, modern, and practical.
- The Kiss: Just barely brushing the floor. The understated and sophisticated gold standard.
- The Puddle: Allowing 2-4 inches of extra fabric to pool on the floor for a romantic, indulgent feel.
5. Measuring Based on Your Hardware
- Rings & Hooks: Measure from the bottom of the ring or eyelet to the floor.
- Grommets: Measure from the top of the rod to the floor, then add a 1.5" header (the fabric sitting above the rod).
