How to Measure for Curtains: A Simple Guide for Perfect Fit

Measuring for curtains may seem like a daunting task, but it can be quite straightforward with a few simple steps. Accurate measurements are crucial to achieving the perfect fit for your window treatments, ensuring that your curtains provide the desired look and functionality. Begin by measuring the width of your window from one end of the frame to the other. Then, consider the length, depending on whether you prefer floor-length curtains or ones just above the sill. With these measurements in hand, you can choose the right curtain rods and styles for your home, creating a beautiful and cohesive look.

Curtain or Valance sizes:

When measuring for curtains or valances, it’s crucial to understand some key principles. For curtains with rod pockets or grommets, the width listed is the flat-out width. To achieve a full and attractive appearance, you should not stretch the panel to cover an identical window width. Instead, plan on two to three times more fabric. For instance, a 60″ wide panel should ideally cover a window width of 20″ to 30″. As a general guideline, two grommet panels will cover around 40″ of window space comfortably. When dealing with pinch pleated curtains, the fullness is already sewn into the panels. If you have a pair of 48″ wide drapes, they will cover 48″ but with additional considerations for overlaps and returns, you might cover closer to 36″. These overlaps, usually around 12″, allow the left and right panels to overlap correctly when closed, while returns wrap around from the rod to the wall.

Measurement Guidelines for Different Curtains

• Rod Pocket/Grommet Curtains: 
  • Use two to three times the window width for fullness.
  • A standard set of grommet panels can cover 40″.
• Pinch Pleat Curtains: 
  • Ensure to factor in 12″ for overlap and returns.
  • A pair of 48” pinch pleat drapes typically covers around 36”.

Tips for Specific Curtain Types

• Eyelet Curtains: These typically require more panel width for adequate fullness.
• Pencil Pleat Curtains: Similar to pinch pleated options, they often have fullness built into the design.
• Custom Curtains: When ordering custom sizes, always provide accurate measurements to ensure perfect fit and fullness.

For valances, measure the width of your window, extending the rod by 2 to 3 inches beyond the frame to allow for proper coverage. If the valance is gathered, you’ll need to use 1½ to double the width of your window for a full look. Remember that all sizes are denoted as width by length (left to right by top to bottom). Choosing the right size ensures your window treatments provide both functionality and aesthetic appeal.

Measuring Your Window: Width

Start by measuring the width of your window frame using a steel tape measure. Note the measurement in both inches and centimeters if needed. Then, determine the curtain rod length by extending it beyond the window frame by several inches on each side for a fuller appearance. To ensure proper fullness, multiply the window width by at least 2. For deluxe fullness, use a multiplier of 2.5, and for ultra-fullness, multiply by 3. For example, a 36-inch wide window would require curtains at least 72 inches wide for standard fullness. Use a pencil and paper to record these details.

Measuring Your Window: Length

To find the right curtain length, measure from the top of the rod to the desired endpoint. For curtains that rest just above the windowsill, measure to just slightly below the sill. Sill length curtains typically hang at about 63 inches for standard-sized windows. Floor-length curtains are more common and usually hang about 3/8 of an inch above the floor, perfect for everyday use. If you prefer a more luxurious look, you can add 6 to 12 inches to the length for puddle curtains, but keep in mind they are less practical for frequent handling. Consider high ceilings or placement near a radiator when deciding on the exact length. Using hemming tape can help you adjust the length more easily.
