Curtains are an essential part of any room’s décor. They provide privacy, block out light, and contribute to the overall ambiance of a space. However, it can be challenging to know how to measure curtains to ensure they fit your windows perfectly. In this article, we will provide a step-by-step guide to measuring curtains accurately, essential tools you’ll need, tips to guarantee accuracy, and common measuring problems you may encounter.

Step-by-Step Guide for Measuring Curtains

Before you can purchase your curtains, you’ll need to measure your windows to ensure you buy the right size. Follow these steps for accurate measurements:

Measure the Window Frame

Start by measuring the window’s width and height. Measure the width from the left to the right inside the frame, then measure the height from the top of the inside frame to the bottom.

Determine the Curtain Rod Placement

Decide where you want the curtain rod to sit above the window frame. Keep in mind that the placement of the rod will affect the overall look of the curtains. A standard placement is six inches above the window frame.

Choose the Curtain Length

You will need to decide how long you want your curtains to be. Measure from the curtain rod placement to the floor to determine the length. If you want a more dramatic effect, you can add a few extra inches to the length to create a “puddling” effect. Keep in mind that curtains usually come in standard lengths, so you may need to adjust your measurements slightly to accommodate this.

Determine the Curtain Width

To get the curtain’s width, use the window frame’s width measurement and multiply it by two or three. This will allow for a full look when the curtains are closed. You can also use your personal preference to determine the ideal width.

Account for Extra Fabric for Hemming

If you plan on hemming your curtains, add an additional one to three inches to the length measurement to allow for a hemmed edge. Always double-check the measurements to ensure accuracy.

Essential Tools for Measuring Curtains

Measuring curtains requires a few essential tools to ensure accuracy. These include:

  • Measuring tape
  • Ladder
  • Pencil
  • Additional tools such as a level or cordless drill if needed

Tips for Ensuring Accuracy in Curtain Measurements

Follow these tips to guarantee accurate measurements:

  • Measure twice to ensure accuracy
  • Account for variations in fabric color and texture
  • Allow for margins for hemming
  • Consider enlisting a partner to double-check your measurements

Different Types of Curtains and How to Measure Them

There are several different types of curtains you can choose from, each requiring unique measurements:

Grommet Curtains

Grommet curtains have metal rings at the top that slide onto the curtain rod. These curtains are easy to install and require you to measure the diameter of the metal grommet to determine the rod’s size.

Tab-Top Curtains

Tab-top curtains have loops sewn into the top of the fabric that creates an opening for the rod. Measure the distance between the tabs to determine the curtain’s width and the fabric’s length for the height measurement.

Rod Pocket Curtains

Rod pocket curtains have a sleeve sewn into the top of the fabric that allows the rod to slide through. Measure the rod’s diameter to determine the correct pocket size and measure the fabric’s length for the height measurement.

Troubleshooting Common Curtain Measuring Problems

Measuring curtains can come with unique challenges. Here are some common problems you may encounter and practical solutions:

Irregularly Shaped Windows

If you have an irregularly shaped window, take measurements for each section, treating each as a different window. Then, add the measurements together to determine the total size of the curtains required.

Incorrect Measurements

If you accidentally measure a window incorrectly, you may need to purchase additional fabric or resize the curtains. It’s essential to measure twice, double-check your measurements, and take your time to avoid any mistakes.


Measuring curtains accurately is crucial to achieving the right look and function for your space. Remember to measure twice, account for variations in fabric, and choose the appropriate style for your windows. With these tips, you’ll be sure to get the perfect fit for your curtains.
