To clarify your query about what size curtains I need, we have represented this blog post with a step-by-step guide. This will help you measure the right length, width, and fullness ratio for standard to exceptional window curtains.

How to Measure Your Window?

To determine the right size of your window, you must know the right way to measure its dimensions. Have a look at the steps below for accurate measurement of your window width and length for perfect sheer curtains.

Step 1: Measure the Width Of The Window Frame

Measure the width of the window frame using the right tool, which is a measuring tape. Hold one end of the tape and start measuring the window horizontally. Start from the outer end of one side of the window frame to the outer end of the other side. See the figure on the tape, and this is your window width.

Step 2: Measure Height From Rod To Desired Length

After measuring the window width, the next step is to calculate the window height or the length from the curtain rod to the floor or to the length you need to achieve. Floor length is the vertical dimension of your drapes that barely touches the ground. Sill length means the curtain length that ends at the lower end of the window. Whereas the puddle means your curtains are longer than the floor limit, and they rest on the floor for a stylish impact.

Tips For Different Curtain Styles (Floor-Length, Sill-Length, Puddle)

Follow the expert tips while measuring the window’s width and length for the right curtain styles.

• Measure the length of the window to the floor, or just 1-2 cm above it, to achieve a tailored, neat look with silk curtains that touch the floor.
• For sill-length style drapes, measure the length from top to 1cm below the window’s lower end. So, after preparation, your curtain will be 1 cm above the window sill for a perfect look.
• For puddle-style drapes, when measuring the window vertically, your endpoint should be the floor. Then add 1-2 inches of extra length to get the puddle-length drapes.

Determine Curtain Width

You can calculate the width of your bedroom curtains from the window width you have measured. The final drape width should be wider than your window width. Read the description below for a better understanding.

Rule Of Thumb: Curtain Width Should Be 1.5x To 3x The Window Width

As a general rule, your window cover width should be 1.5 to 3 times the window width. This extra measurement will provide full window coverage, filling the gaps on either side, and give space to curtain folds to set smoothly & deeply for an elegant look. If your window width is about 60 inches, then add 6-12 inches for gap filling. Your final curtain width will be 72 x 1.5 = 108 inches, 72 x 2 = 144 inches, or 72 x 3 = 216 inches, depending on the required fullness.

How Curtain Width Affects Fullness And Gathering

The drapes’ width will directly affect the fullness and gathering. The wider the width, the higher the fullness and the gathering. Fullness is the ratio of your curtain width to the window frame. While gathering is the way to reduce the curtain width after stitching or to achieve the final look of your drapes after making the fold or pleats. You can adjust the drapes’ width to achieve the following fullness and gathering.

• For maximum fullness & gathering, multiply the window width by 3. This will create more folds for a gathered, luxurious effect. This is usually achieved with the hotel curtains.
• For a sleek, modern look, you can multiply the curtain width by 2, creating a sophisticated, balanced effect. This is widely used in living room curtains.
• For a contemporary look, usually achieved in casual places. In this fullness ratio, your curtains will appear soft & minimalistic. This is acquired by multiplying your window width by 1.5.

Single Panel Vs. Multiple Panels

When calculating the final window curtain width, the panel selection matters. For a single panel, the final width will be equal to your measured curtain width. For multiple panels, divide the total drape width by the total number of panels to get the width of each panel. For example, if your drape is 120 inches wide, then the panel will be of the same width. But for 2 panels, it will be 120/2=60 inches for each panel.

Determine Curtain Length

Once you have evaluated how wide your curtains will be, the next step is to assess your curtain length. For a better idea, go through the following description.

Floor-Length, Sill-Length, Apron-Length Options

• Prefer floor-length curtains for areas where you need a sophisticated, neat look.
• Sill-length drapes are good for practical rooms where you need easy, quick maintenance. Kitchen and bathrooms are the best places for this style. If the furniture is placed in front of the window, then this length style will give a casual yet formal impact.
• Apron-length curtains (reaching 2-5 inches below the bottom of the window and high above the ground) are best for living rooms that receive high foot traffic.

How Rod Placement Affects Curtain Length

The placement of curtain rods will affect the length you want to achieve. The general rule is to place the rod high and wide on your window. If the rod is close to the window’s upper edge, the hung curtains will appear smaller, creating an incomplete room aesthetic.

Similarly, if the rods are higher above the upper window, the drapes will hang nicely with an elongated effect. They will create an imaginary vertical impact, making your room ceiling look higher with longer drapes. Keeping them close to the ceiling in larger rooms will give them a taller and broader effect.

Tips For Achieving A Polished Look

Hence, for a polished, balanced look in your space, follow the tips below when determining the best length for drapes.

• Measure the window’s length accurately.
• Select the curtain length style that best suits your window and the room’s function.
• For less active areas, sill-length or apron-length drapes are best.
• Choose full-length, durable drapes for busy rooms, as they resist daily wear and tear.
• For rooms with kids and pets, apron length will be a good option.
• For dramatic effect, puddle-length drapes are suitable.

Consider Curtain Style and Fabric

When choosing drapes, give careful attention to the desired style and fabric to achieve the aesthetics you want while meeting your space needs.

Sheer Vs. Blackout Curtains

The fabric selection for your drapes affects light control, privacy, energy efficiency, and the overall mood and style of your space. Sheer curtains are made from the lightweight fabric, while blackout curtains are made from heavy fabric. Voile, lace, chiffon, or net are lightweight fabrics that diffuse light and provide some privacy. Linen and velvet are blackout fabric options that block light completely, providing 100% darkness and the highest level of privacy.

Heavy Vs. Lightweight Fabric Considerations

If you want an energy-efficient drape with more light control and sound-dampening properties, opt for a heavy fabric like brocade, velvet, or linen. They give a fine look with a good level of privacy. For an airy and soft look, consider choosing lightweight fabrics. They are easy to hang on every style rod and are easily adjustable to different heights.

How Header Style Affects Width And Length Choices

The header style of your drapes will affect the curtain width and length choices. We need to decide on the extra width for fullness and the right curtain drop. The common heading styles include tab-tops, rod pocket, grommet, or eyelet curtains. They create a sleek look and need less fullness than the pleated curtains. The heading also affects the length to which you need to hang your drapes.

For grommet & eyelet curtains, the curtain drop is measured from the upper end of the rod to the floor. Whereas for pleated window curtains, the measurement starts from the hook to the floor. As the pleats are pinched, they make neat folds that reach the floor. With this style, you can hang drapes at floor length to make the room’s ceiling taller. Tab top and rod pocket look good in sill-length or apron-length for a casual look..

Special Cases

For special or complex windows, you need to pay closer attention when measuring the width and length. This will help you get the perfect fit drapes for a harmonious effect.

Bay Windows

As you know, bay windows consist of three or more panels that extend outward. To take dimensions, measure each window separately. Start at one end of the window frame and work to the other, including any trims. You can place one single rod for the entire window or a separate panel for each window. For right-sizing, follow the exact instructions for width and length as we have discussed for the regular standard windows.

Sliding Doors

To determine the right size for sliding door curtains, measure the sliding doors. Start by measuring the doorframe from one side to the other, including any protruding handles or locks. For length, measure the door frame from top to desired sill, apron, full, or puddle length. Make sure the curtains are wide and easy to open.

Unusually Shaped Windows

For arched, irregular, or angled windows, measure the window from three different points. Measure the length from the uppermost point of the window to the desired length. For width, measure the rod width that is fixed on the window. You can use a single rod for these windows and get a customized rod that complements the window shape.

Layered Curtains And Double Rods

When layering sheer with heavy blackout curtains, the essential thing is to hang them on double rods/tracks. After measuring the window, adjust the width of both curtains for fullness. As sheer curtains are light in weight, they require more fullness than heavy curtains. For lengths, make sure the sheer window curtains are slightly longer than the floor for a luxury look. In comparison, it would be good if the blackout drapes touch the ground or just above the floor for a sophisticated look.

Tips for Accurate Curtain Sizing

When measuring windows for the right-sized curtains, follow the tips below.

• Measure the windows twice and record the measurements to calculate the curtains’ accurate dimensions.
• If you are selecting natural fabric for drapes, consider their shrinkage to avoid undersizing. Washing the fabric before stitching the drapes would be a good idea.
• Do not forget to leave an extra allowance for hardware and pleats.
• Use a steel tape to measure window dimensions, as fabric tape increases the risk of error.

Conclusion

The right size for your drapes will enhance the aesthetics and functionality of the space. Choosing the correct curtain size is essential to ensure full window coverage for light control and privacy. Your curtains, with the proper width and length, enhance the room’s perception and style through their fullness, length, and fabric. If you want a perfect look with complete and balanced decor, you must select the right drapery. At the end, we would like to say follow this guide for a perfect fit and style for the curtains.
