How to Measure Curtains Like a Professional: The Complete Guide to Choosing the Perfect Curtain Size

Choosing beautiful curtains is only half the journey—the right measurements are what create a polished, custom-made look. Curtains that are too short, too narrow, or incorrectly installed can make even the most luxurious fabric look unfinished. By taking accurate measurements before ordering, you can achieve the elegant, designer-inspired appearance every home deserves.

At Lilijan Home, we specialize in custom-made curtains crafted to your exact specifications. This step-by-step guide will help you measure your windows correctly and determine the ideal curtain size for your space.


Step 1: Measure Your Curtain Rod, Not Your Window

One of the most common mistakes homeowners make is measuring the window frame instead of the curtain rod.

Always measure the full width of the installed curtain rod, including any decorative finials if your curtains will cover them. If you haven't installed your rod yet, it should extend 6–12 inches (15–30 cm) beyond each side of the window. This allows your curtains to stack neatly when open and lets in more natural light.

Example:

  • Window Width: 60 inches

  • Recommended Curtain Rod Width: 72–84 inches

The wider your rod, the larger and more luxurious your windows will appear.


Step 2: Choose the Correct Curtain Length

Curtain length has a significant impact on the overall appearance of your room.

Sill Length

Ends at the window sill.

Best for:

  • Kitchens

  • Bathrooms

  • Laundry Rooms

Apron Length

Ends approximately 4–6 inches below the window.

Ideal for:

  • Casual spaces

  • Small windows

Floor Length (Most Popular)

Curtains stop about ½ inch above the floor, creating a clean, modern appearance.

Perfect for:

  • Living Rooms

  • Bedrooms

  • Dining Rooms

  • Home Offices

Puddle Length

Curtains extend 2–6 inches onto the floor, creating a luxurious designer look.

Best suited for:

  • Formal Living Rooms

  • Luxury Bedrooms

  • Elegant Dining Rooms


Step 3: Measure Curtain Height Correctly

Measure from the top of the curtain rod (or the curtain ring, depending on your heading style) to your desired finishing point.

Many interior designers recommend installing the curtain rod 6–12 inches above the window frame to create the illusion of taller ceilings.

Floor-to-ceiling curtains make almost every room appear larger and more elegant.


Step 4: Consider Your Curtain Heading Style

Different heading styles require slightly different measurements.

Lilijan Home offers multiple heading options, including:

  • Back Tab

  • Rod Pocket

  • Grommet (Eyelet)

  • Pinch Pleat

  • Pencil Pleat

  • Clip Rings

  • Hook Rings

  • Traverse Rod Tape

Each heading style hangs differently, so measuring from the correct starting point is essential for achieving the desired finished length.


Recommended Curtain Fullness by Fabric Type

Different fabrics create different draping effects.

  • Sheer Curtains: 2.5–3× fullness for a soft, flowing look.

  • Semi-Sheer Curtains: Around 2× fullness for balanced light filtering and privacy.

  • Linen & Linen Texture Curtains: 2–2.5× fullness for a relaxed, elegant drape.

  • Velvet Curtains: 1.8–2× fullness due to the fabric's weight.

  • Blackout Curtains: 2× fullness for excellent coverage and a luxurious appearance.


Common Measuring Mistakes to Avoid

Avoid these common errors when ordering custom curtains:

  • Measuring the window instead of the curtain rod.

  • Ordering curtains that are the same width as the rod.

  • Hanging the rod too close to the window frame.

  • Forgetting to account for curtain rings or pleats.

  • Choosing curtains that are too short.

  • Not considering fabric fullness before ordering.

Taking a few extra minutes to measure correctly can make a dramatic difference in the final appearance of your window treatments.
