How to Use the Curtain Size Calculator

Step 1: Measure Your Window

Using a tape measure, accurately measure the width and height of your window in inches. For width, measure from the outer edge of one side of the window frame to the other. For height, measure from where you plan to install the curtain rod to where you want the curtains to end.

Step 2: Enter Window Dimensions

Input the measured width and height into the respective fields in the calculator. Ensure you’re using inches and double-check your numbers for accuracy.

Step 3: Select Curtain Fullness

Choose your desired curtain fullness from the dropdown menu. Options include Standard (2x), Deluxe (2.5x), and Ultra (3x). This determines how gathered or full your curtains will appear when closed.

Step 4: Choose Curtain Style

Select your preferred curtain style from the options provided. This could be standard length, floor length, or puddle style, which affects the overall height of your curtains.

Step 5: Specify Rod Type

Indicate whether you’re using a standard or decorative curtain rod. This choice can impact the final height calculation for your curtains.
