Do you need 2 curtain panels per window?

Quick Answer

The quick answer is that it depends. Some key factors to consider when deciding if you need 1 or 2 curtain panels per window include:

  • Window size – Larger windows often look better with 2 panels, while smaller windows may only need 1.
  • Room size – 2 panels can help a window feel more proportional in a larger room.
  • Curtain panel width – If the panels are very wide, 1 may suffice. Narrower panels usually require 2.
  • Privacy needs – 2 panels provide more coverage for privacy.
  • Light control – 2 panels generally provide better insulation and light blocking.

So in summary, for larger windows, rooms, and better light control/privacy, 2 panels are recommended. But 1 wider panel can work for smaller windows. Go with what looks most proportional and meets your specific needs.

Do you really need two curtain panels per window?

When it comes to choosing curtain panels for your windows, one of the most common questions that comes up is how many panels you need per window. The short answer is that there is no definitive rule – it truly depends on your specific window, the look you want, and your own personal preferences. However, there are some general guidelines you can keep in mind.

Here are some pros for using two curtain panels per window:

  • It creates a fuller, more luxurious look. Two panels simply drape more elegantly on either side of the window compared to a single panel.
  • It provides more privacy. With two panels, you can be certain no gaps will be left uncovered.
  • It enables better light filtering. During the day, you can draw both panels to dim the incoming light.
  • It offers more insulation. Two layers of fabric help trap heat in winter or block sun in summer more effectively.
  • It looks more proportional on wider windows. A single panel might look skimpy or get lost on a big window, whereas two balance it symmetrically.

On the other hand, there are also some reasons one panel per window can work just fine:

  • It’s often sufficient for smaller windows. One wider panel can cover a narrow window perfectly without needing two.
  • It allows more light in. With just one panel, you can leave the window partially uncovered to retain some natural lighting.
  • It provides easier access to the window. You only need to draw back one panel to open or access the window easily.
  • It’s more economical. You only need to purchase half the number of panels.
  • It creates a leaner, sleeker look. Some contemporary rooms look best with a minimal single panel style.

Window Size and Room Size

Two major factors to consider are your actual window size and the room size the window is in.

For very small, narrow windows like those in bathrooms or kitchens, a single curtain panel is usually sufficient. Even if you purchase wide panels meant for larger windows, trimming them down to properly fit a tiny window often results in a finished width comparable to regular smaller panels anyway. So there’s no real advantage to using two here.

However, as your windows get wider, two panels really become more useful. A single panel on a very wide window can appear skimpy, get blown around in breezes, and not provide full coverage. Using two panels on large windows like sliding glass doors helps them feel properly dressed.

The room size also impacts the decision. A window that feels nice and wide in a small room may look narrower in a large open space. Consider the window proportions compared to the wall size. In a big room, two panels can help anchor the window and make it feel intentional.

As a general guideline:

  • For windows under 30 inches wide, 1 panel is usually sufficient
  • For 30-60 inch windows, 1 or 2 panels can work depending on other factors
  • For over 60 inch wide windows, 2 panels tend to look best

But it still depends on your room and personal taste. A small living room window could still suit two panels nicely, while a large kitchen window may only need one if it has an unobstructed view.

Curtain Panel Width

The width of the actual curtain panels themselves is also very important.

If you purchase or make very wide panels, then you may only need one per window. A single 100 inch wide panel, for example, can cover a standard window nicely on its own. But such wide panels may not be common or easy to find.

More often, people are working with narrower curtain panels in standard widths like 40-50 inches. In this case, most windows will need two panels to entirely cover each side fully.

Again, think about the width of your specific window. If a single 50 inch panel leaves 10 inches of window exposed on either side, then going with two narrowed down to 25 inches apiece makes a better fit.

But if your wide window is 60 inches across, a single 60 or 80 inch wide panel could work beautifully to cover it alone.

Some typical curtain panel widths and combinations include:

  • 2 20-25 inch panels for a standard small to medium window
  • 2 30-40 inch panels for a larger window
  • 1 60-inch panel for a standard width single window
  • 1 100-inch wide single panel for a sliding glass door or two adjacent windows

Aim to have your panels overlap the window frame by at least 2-3 inches on either side for full coverage. Account for whether the panels puddle at the bottom or just below the frame as well. This will help you determine the ideal widths.

Privacy Needs

If privacy is a top concern, two curtain panels per window are always recommended. With a single panel, even when fully drawn, there is the risk of small gaps at the edges of the window being uncovered. People could potentially peek through these gaps from outside, especially at night when there is light within the room.

With two panels fully drawn, you can be sure no such gaps will exist and complete privacy is achieved. This is especially important for windows that are low or close to walkways where people could see in. Rooms like bedrooms and bathrooms benefit most from the added privacy factor of two curtain panels instead of one.

On the other hand, if your windows already have blinds or shades behind the curtains, or if they don’t face any risk of people seeing in, the extra privacy from two panels may not be as necessary. A living room window that faces the backyard or a second story window likely only needs one out of aesthetics alone.

Light Control

Curtains typically serve a dual purpose of both decoration and utility. On the utility side, blocking light is a major consideration. Again here, two panels have an advantage over one.

With two curtain panels on each window, you double the ability to filter and block light based on your needs throughout the day. At night, you can draw them both fully closed to prevent any exterior light like street lamps from disturbing your sleep.

In the mornings, you can leave one panel open to let in some natural light while keeping the other drawn for softening the glare. And during the day when midday sun is streaming in brightly, you can block it out entirely by using both closed panels.

The added layer of fabric from the second curtain panel acts like extra insulation against sunlight and heat too. This helps keep rooms cooler in summer.

With a single curtain panel, you lose a lot of this nuanced control over the amount of incoming light. Your only options are fully open or fully drawn. And when drawn, there is less material to thoroughly block harsh light.

So for functionality, energy efficiency, and comfort, two panels beat one for better regulating light in your rooms.

Look and Style Preferences

Beyond the practical factors above, the number of panels per window ultimately comes down to visual appeal and what pleases your eye. It’s your home, so the aesthetic look you like is most important!

Here are some style considerations that can help decide one vs. two panels:

  • Formal vs. casual decor – For a formal living room or dining room, two panels create an elegant fullness and frame the window nicely. In more casual rooms, one relaxed panel has a simpler charm.
  • Busy vs. clean look – Some people like the symmetry of two panels that balance the window. But others prefer the minimal, clean sightlines of just one panel, avoiding a busier look.
  • Traditional vs. modern design – Two panels fit better with traditional spaces, while contemporary rooms often suit the sleeker style of one wide panel.
  • Texture interests – Deep colors, patterns, or textures in panels can benefit from doubling up to really showcase the details.

Knowing the overall vibe you want for a room helps determine if one or two curtain panels fit best. Stand back and consider the window within the whole space for a holistic design decision.

Mix and Match per Window as Needed

One final note – you don’t have to stick with the same number of panels on every window within a room or home. Feel free to mix and match different windows with one or two panels depending on what works best for each individual size, privacy needs, and style.

Some variety can actually help add more design interest and customization to your space. Just be sure to maintain a sense of overall harmony so windows don’t clash.


In summary:

  • Larger windows usually look best with two panels, while smaller windows only need one.
  • Two panels provide more light filtering ability and privacy compared to one.
  • Narrow panels around 25-40 inches wide each normally need two per average window.
  • Very wide panels over 60 inches may only require one.
  • Ultimately choose the number that meets functional needs but also looks most pleasing to your eye.

Follow the general guidelines but don’t be afraid to mix and match as needed per window. Tailor your decision to the space both practically and aesthetically for the best curtain design.
