Choose Your Curtain Type

Different curtain thicknesses require different fullness recommendations

Sheer Curtain

Bigger fullness ratio recommended for soft top headers to achieve a fuller look.

Blackout / Room Darkening / Light Filtering Curtain

For standard 1 and 2 layer options only — 4-layer soundproof curtains are listed separately.

4-Layer Soundproof Curtain

Smaller fullness ratio for soft top headers so the curtains won't feel too heavy or difficult to draw.

STEP 1

SELECT YOUR HEADER STYLE

Grommet Header

Metal rings are evenly set into the top of the curtain, allowing the rod to pass through directly, creating smooth and uniform wave-like folds.

Soft Top Header

Applies to back tab, rod pocket headers.The rod slides through fabric loops or a sewn pocket, leaving a clean, seamless top.

Pleated Header

Applies to double French pinch pleat, triple French pinch pleat, inverted box pleat, goblet, Euro pleat headers.

Pleat Hook & Clip Ring Header

The curtain header has a sewn-in fabric tape at the back. For 4-layer soundproof curtains, only pleat hook is available.

STEP 2

DETERMINE CURTAIN WIDTH

ROD INSTALLED

NO ROD INSTALLED

For Pleated Header

The fabric's fullness is already factored into the design. We use 200-230% fabric fullness to create the pleats, ensuring the curtains have a rich and luxurious appearance.

This means only a 1.1x fullness is needed for French pinch pleat, Euro pleat, inverted box pleat, and goblet headerstyles.

200% to 230% built-in fullness

15%-25% stack width

For Soft Top Headers

* Back Tab & Rod Pocket
* Single / Double Rod Pocket

The recommended fullness ratio vary depending on the thickness of the curtain fabric:
* 2x fullness for sheer curtains
* 1.5x fullness for single/double layer blackout/room darkening curtains
* 1.2x fullness for 4-layer soundproof curtains (larger fullness may make 4-layer soft-top curtains too bulky and difficult to open)

15%-25% stack width

For Grommet Headers

The recommended fullness ratio for grommet headers is 1.5x.

Because each grommet ring creates a slight angle around the rod, the curtain cannot lay completely flat. If your ordered width matches the rod width, the curtains won't fully cover the window when closed. That's why it's important to add extra fullness for better coverage.

10%-20% stack width

For Pleat Hook & Clip Rings Headers

4-prong pleat hooks create structured, fixed pleats at the top of the curtain, which naturally requires more fabric to achieve a full, elegant look. To ensure proper coverage and avoid a flat appearance, we recommend a 1.5x fullness ratio for this header style.

15%-20% stack width

STEP 3

DETERMINE THE HEIGHT OF YOUR CURTAIN PANEL

MEASURE FROM ROD BOTTOM TO FLOOR

NO ROD: WINDOW FRAME TO FLOOR + EXTENSIONS ON TOP

The height you enter when placing the order follows our curtain length rules and refers to the finished curtain length(with an industry-accepted tolerance of ±1-2"), measured from the very top to the very bottom of the curtain in its fully hanging position — including the header.

If you're using our measurement tool, simply measure the distance from the bottom of the curtain rod or track to the floor, excluding rings or runners.

Based on your selected header style and finish length style (hover or puddle), we'll make the necessary height adjustments automatically. Place your order using the calculated result or consult with our customer service at support@thehues.com for a personalized solution.

STEP 4

SELECT YOUR FINISH LENGTH

Hover

Puddle

When choosing between different curtain lengths, there are two popular styles that can be selected in our measurements guide:

Hover: Curtains “hover” just above the floor for a clean, modern look. (Default adjustment: -1” from floor measurement)

Puddle: Curtains extend slightly onto the floor for a more elegant, dramatic effect. (Default adjustment: +3” from floor measurement)

STEP 5

DECIDE THE NUMBER OF PANELS

1 Panel

2 Panels

1 Panel: Choose 1 panel if you prefer a single curtain that pulls to one side when opened.

2 Panels: Choose 2 panels if you'd like the curtains to split in the middle and open to both sides — this is the most common choice for a balanced look and easier operation.

Curtain Panel Width Calculation

The total curtain width you enter will be split evenly based on the number of panels selected: * If you choose 1 panel, the panel width = total width * If you choose 2 panels, each panel width = total width ÷ 2

If you're using our measurement tool, it will automatically calculate the width of each panel based on the number of panels selected.

FAQ

Curtain Measuring & Installation Guide

Are the ordered width and length the final size of my curtains?
Yes. The measurements you enter represent the finished curtain size based on your curtain measurements. Please note that a slight variation of ±1-2 inches is possible due to industry-accepted tolerances, fabric properties, or necessary adjustments for product functionality.
How do I choose the right fullness for my curtains?
Fullness affects the overall curtain width and appearance. Some people prefer a looser drape for a soft, modern style, while others want a fuller, more gathered look for elegance.

Our curtain size guide recommends fullness ratios between 1.5x to 2x, meaning the total curtain panel width equals 1.5 to 2 times the rod length.
What if my windows or installation scenario is more complex?
This curtain measurement guide provides general recommendations, but some setups — like bay windows, arched frames, or floor-to-ceiling drapes — require more customized planning.

For tailored advice, feel free to email us at support@thehues.com and our specialists will help you choose the best curtain dimensions for your space.
Does this guide apply to outdoor curtains?
Yes. This guide can be used for both custom indoor and outdoor curtains. However, measuring for outdoor curtains is generally simpler, and we recommend using the measurement tool provided on the respective product detail page for the most accurate results.
