Why Curtain Sizing Matters?

Curtains do more than cover windows; they set the tone for an entire room. Selecting appropriate length and width measurements is crucial in creating an inviting aesthetic and an inviting look in any setting. Curtains must reach between just kissing the floor or pooling dramatically below sill level for proper function and aesthetics.

How to Calculate Curtain Length and Width?

Measuring Your Window for Curtain Length

Choosing the right length depends on both personal preference and the room’s function. Here are the most common curtain-length styles:

Sill Length: Curtains end just above the window sill. This works well for kitchens and bathrooms.
Apron Length: Curtains hang slightly below the sill, typically 4 to 6 inches. This style suits casual spaces like dining rooms.
Floor Length: Curtains reach the floor, giving a polished and formal look. This is ideal for living rooms and bedrooms.
Pooling: For a luxurious effect, add 6 to 12 inches of extra fabric to the curtain length so the material pools on the floor.

To calculate your curtain length:

Measure from the top of the curtain rod to where you want the curtain to end.
Add extra inches for pooling if desired.

The formula for Curtain Length:

Standard length = Window Height + Rod Height
Pooling Length = Window Height + Rod Height + 6 to 12 inches

Example: If your window height is 84 inches and your curtain rod is installed 4 inches above the frame, your standard curtain length will be 88 inches. If you want to pool, you would add 6 inches for a total length of 94 inches.

Calculating Curtain Width

The correct curtain width ensures the panels cover the window entirely and hang elegantly on the sides when open. As a general rule, the total width of your curtains should be 1.5 to 3 times the window’s width, depending on the desired fullness.

Standard Fullness: Multiply the window width by 2.
Deluxe Fullness: Multiply the width by 2.5.
Ultra Fullness: Multiply by 3 for a luxurious, gathered look.

The formula for Curtain Width:

Curtain Width = Window Width × Fullness Factor

Example: If your window is 60 inches wide, for deluxe fullness, you would need curtain panels with a combined width of 150 inches (60 × 2.5).

If you’re working with curtain panels, divide the total width by the number of panels you’re using to determine each size.

How to Decide Curtain Rod Length?

Curtain rods should extend beyond the sides of the window to ensure the curtains frame the window properly when open. This also allows more natural light into the room.

Rod Length Formula:

Rod length = Window Width + 6 to 12 inches on each side

Example: If your window is 48 inches wide, your curtain rod should be at least 60 inches long (48 + 12).

240 cm (94 inches) Window:
Rod Length: 260-280 cm
Curtain Width: 480-720 cm (depending on fullness)
Length: Use the calculator for precise measurement and avoid guesswork.

Should Curtains Touch the Floor?

Yes, in most cases, curtains should either touch the floor or hover slightly above it (½ inch). Floor-length curtains offer a more elegant and complete look, especially in formal spaces like living rooms and dining areas. However, you can let the curtains pool on the floor for a more dramatic effect.

How Far Should Curtains Hang Below a Window?

For apron-length curtains, allow the curtains to extend 4-6 inches below the window sill. This offers a traditional look while still being practical for dining rooms and casual spaces.
