Picking out the correct curtain length for any homeowner’s room might seem like a pretty straightforward task, but that is not the case since it can make or break the complete décor feel of a room. There are guidelines you need to follow to have a cohesive and cozy setup. 

One of those rules is that curtains should graze the floor, which will entail measuring the windows correctly before setting out to purchase or order the fabric. Aside from the curtain size, there are other things to consider, like valance or rod sizes, to achieve a fully streamlined and finished space. [toc]

Standard Curtain Panel Sizes

Curtain or window panels will come in various sizes, some homeowners will have them custom-made to be made on the fabric of their choice, but some would want an already available product ready to be used. 

The good thing about these standard sizes is that they will fit the needs of most households wanting to use curtains for their window coverings. Also, many interior decorators and architects use and consider these numbers. 

The most common size for curtains is 45 inches or 114 centimeters long. This size can efficiently be utilized for most homes, but there are also other curtain sizes available, from 63 to 120 inches or 160 to 305 for homes that need longer curtains for longer walls. 

Standard Tier Sizes

For smaller windows in most bathrooms, above the kitchen sink, or attics that will not require full-length panels, tier curtains are there to add privacy for covering these half windows.

Usually, homeowners purchase tier windows in pairs to easily slide both on the side, just like regular full-length coverings

There are two commonly used lengths for tier curtains, the 24 inches or 61 centimeters and the 36 inches or 91 centimeters tier panels. These lengths are usually available with a standard width of 45 inches or 114 centimeters. 

Like regular full-length curtain panels, homeowners also have the option of having them made custom to fit a window

Standard Valance Sizes

Valance in curtain covering may be a foreign term to some, but once a quick web search is done, any homeowner might recognize valances from the cozy rooms of your grandparent’s home.

It is the strip of fabric used to cover the upper half of any window but is most generally seen on the full covering setup of bay windows. Valances also hide curtain rods, window blinds, or shades.  

The standard valance will have a width of 50 inches or 127 centimeters from side to side and a depth of 3 to 5 inches or about 8 to 13 centimeters. Depths can easily be adjusted according to the homeowner’s window style and the valance design

Curtain Size Chart

One of the most straightforward modes to determine a rough estimate of the curtain length and width you will need is by looking at a size chart.

When looking at a size chart, it is essential that you have an idea about your window length and width measurements to make the chart reading more effortless. 

Window Size   Curtain Size  
Length Width Length  Width
36 inches / 91 centimeters 36 inches / 91 centimeters 63 inches / 160 centimeters 48 inches / 122 centimeters
44 inches / 112 centimeters 36 inches / 91 centimeters 84 inches / 213 centimeters 48 inches / 122 centimeters
52 inches / 132 centimeters 36 inches / 91 centimeters 96 inches / 244 centimeters 48 inches / 122 centimeters
54 inches / 137 centimeters 36 inches / 91 centimeters 108 inches / 274 centimeters 48 inches / 122 centimeters

Wider Window Panel Sizes 

Panels are stationary curtains pushed to the sides to frame windows and even doors. Aside from the most common 45 inches or 114 centimeters width of panels, there are wider products that any homeowner can utilize whether they want a fully gathered or a simple gathered setup. 

For wider widths outside the standard 45 inches or 114 centimeters panel, there are the 63 inches or 160 centimeters and 84 inches or 213 centimeters products. If you have an even wider window or a full picture window, it is better to frame them using curtains with a width of 95 inches or 241 centimeters. 

The widest panel width any homeowner could get from most stores without having it made custom is 108 to 120 inches or 274 to 305 centimeters. 

Curtain Length Sizes

Aside from the panel’s width, there is also the length factor to consider, which is essentially the most important thing to ensure the full aesthetic effect of window coverings in a room. There are four lengths you can get ready-made in most décor and furniture stores, and they will be available in several types, from sheer to satin to blackout, etc. 

The four standard curtain lengths are 63 inches or 160 centimeters, 84 inches or 213 centimeters, 96 inches or about 244 centimeters, and the longest at 108 inches or 274 centimeters. 

The best choice for rooms with a lower ceiling is curtains at 84 inches or 213 centimeters. At the same time, the most versatile will be the 96 and 108 inches or 244 to 274 centimeters long size

There are three primary styles of how curtains can drape and fall to the floor, and this factor will be affected by the length of your choice. So, if you plan to achieve a specific drapery fall effect, it’s best to pick the size correctly. 

Curtain Puddling Length

Curtain puddling length sizes

The base word for puddling is puddle, and from that, we can deduce that curtains following this fall effect will be made to look like a puddle. You can often see puddling lengths for more stately and official buildings to achieve the more traditional covering style. This style will work best for thicker curtain fabrics like velvet, something you usually see on the sides of theater stages. 

If you want minimal puddling, add 1 to 3 inches or 3 to 8 centimeters to the final length of your curtains. Moderate puddling will require up to 3 to 6 inches or 8 to 15 centimeters of additional height.

At the same time, an opulent drape with a larger amount of fabric gathered to the floor will require at least 6 to 8 inches or 15 to 20 centimeters of additional curtainheight. 

Curtain Floating Length

The floating curtain fall style will look best for sheer and willowy fabrics to frame windows with a panoramic view. Homeowners can choose to add another layer of material to these to add the effect that they are floating. 

This floating effect is named because of the open space between the curtain’s end and the floor, making cleaning easier than puddling on the floor. If you have pets around the house, it is better to employ the floating style so your pets won’t reach them. 

To achieve this look, drill your curtain rod 4 inches or 10 centimeters up the window sill. This will give you a space of at least 2 inches from the floor, assuming you are getting the standard length. Homeowners can easily adjust this size by installing higher rods if they want more space between the floor and the panels

Kiss Length Curtains

The floor kiss length is perfect for any homeowner planning to install blackout curtains for their bedrooms. Unlike puddling and floating curtains, kiss length will not spill or hover above your floor. What it will do is stop strictly at floor length. 

The usual approach is to buy curtain sizes long enough to cover the entire height from the floor up to the rod, covering the window completely. Getting longer panels is also a better bet, and simply altering their position to achieve the floor kiss length is the way to go; less risk and more choices with only a bit of alteration required. 

Custom Sizes

Aside from getting curtains in standard sizes available in most décor and furniture stores, one way to buy them, especially if a homeowner requires a specific size, is to have them made to measure.

Custom-made products will be more expensive than ready-made ones, but their main advantage is getting the size perfect for whatever requirements a homeowner has, whether they want it pooling at the end or straight cut to kiss the floor. 

Most services that provide custom window treatments require the rod or the track width and height. Most of them will be the ones to calculate what will work best for the size with your requirements in check, like the material or the pooling style. 

What Size For Sliding Glass Door Curtains?

Curtains typically cover windows, but they are versatile in covering anything that needs privacy, even doors. Sliding glass doors bring light into any room, but sometimes light can be a little overwhelming, especially in the morning; this is why many choose to cover them. 

There are factors to consider when selecting the perfect curtains for a sliding door, and the dimensions are only one. Most sliding door sizes will have a length of 80 inches or 203 centimeters and a width of 60 to 72 inches or around 152 to 183 centimeters. 

For this size, choose a curtain rod 80 inches or 203 centimeters in length to accommodate a door width of up to 72 inches. The lengths are more versatile and will depend on what hang-style you are looking for, but getting coverings longer than the door length of 80 inches is always a safe place to start. 

How To Size Curtains? 

The most important thing to choose the right panel size for your home is to learn how to measure your windows for curtains, and here is how. The first thing to consider is the window’s width. 

You measure the width by taking a tape measure or any measuring device and stretching it from one side to the other. Typically, a homeowner will use at least two or three times the material to achieve a fuller, thicker look. To illustrate, if you have a window width of 36 inches, multiply this size by two at 72 inches per side. 

Standard curtain fullness will have you multiplying the width by two times; multiply by 2.5 times if you want a fuller width when bunched up to the sides. You can always multiply the width by three for optimum fullness. 

For the length, it will only entail measuring from the curtain rod to the bottom whether they want it at floor-length or pooling to the floor. No fixed length will matter since it will depend on a homeowner’s preferences, plus the rod can also be adjusted easily. 

What Size of Curtains Do I Need? 

There are three factors a homeowner will need to consider to figure out what size of curtain they need: style choice, determine window width, and the number of panels they want to use. 

Style choice for window treatments will depend on whether a homeowner wants it at floor or window sill length or if they want their drapery puddling at the end. Once that decision is made, it will be easy to determine their desired size from top to bottom. 

The second is the window width, which has been discussed in detail under how to measure for curtains. The width will determine how full the whole fabric material will look, whether bunched up on the side or not. The more the window width is multiplied, the more “waves” it will have, making it look beautiful and complete.  

Aside from the width, the number of panels a homeowner wants to use will decide how full and beautiful it will look. 

Curtain Rod Sizes 

Curtain rod sizes

Curtain rods come in many sizes to fit any window width. On average, any homeowner can get rods from 24 inches or 61 centimeters to 170 inches or 432 centimeters. 

For smaller windows, there are 24 to 48 inches or 61 to 122 centimeters of curtain rods for laundry areas or guest bathrooms. Regular-sized picture windows benefit from rods at 48 to 84 inches or 122 to 213 centimeters. 

There are more oversized rods, 120 to 170 inches or 305 to 432 centimeters. Oversized rods will be perfect for homes with high ceilings and broader-than-average windows. Visit our curtain rod sizes guide for more details.

Should My Curtains Touch The Floor? 

How a homeowner will hang their drapes will depend on how they want their space to look and other circumstances. Although these coverings look their best when touching the floor (this drape style is sometimes known as kiss length), considerations like pets and how much cleaning a homeowner does at home are essential. 

Panels can only stop at the window sill, especially bay windows with a reading nook or seating. At the same time, coverings for smaller windows like laundry rooms or kitchens will not be able to meet the floor at all. See pictures of kitchen window curtains on this page.

How Far Should Curtains Be Off The Floor? 

Similar to whether or not a curtain should meet the floor, how far from the floor one will hang is dependent on the homeowner’s personal preference. However, some use these installing and decorating tips and tricks to decide.

Curtain Length Style Distance from the Floor Visual Style Practical Considerations
Floating 0.5 to 1 inch above Neat, tailored Easy maintenance & helps avoid dust
Kissing Touches floor Clean design Requires accurate measurement
Puddling Several inches to 1 foot on the floor Elegant, traditional Harder to clean, not for high-traffic areas
To the sill/Below the sill (does not reach the floor) Casual & functional Kitchens/bathrooms & easy to maintain

For homeowners who want to achieve a long and taller look for their space, the best trick is to ensure the wall and not the window will determine their panel length.

Many do this trick by hanging their coverings two to three inches lower than their ceilings. This will add texture to the walls for aesthetic effect and make your space seem taller. See our article about how high to hang curtains on this page.

What Is The Proper Length For Living Room Curtains?

Curtain living room length sizes

Any size coverings you choose for your living will be appropriate, but if you can avoid it, do not choose the standard length of 84 inches or 213 centimeters unless you have low ceilings.

What would work for your living room and make the walls look more extended will be curtains at 96 to 108 inches or 244 to 274 centimeters. 

The golden rule is always longer rather than having it awkwardly short if that is not the look a homeowner is going for. 

Should You Hang Curtains Above Window?

Hanging curtains above the window is an excellent trick if a homeowner wants to make it seem that they have higher ceilings. Some decorators even recommend installing rods close to the ceiling to achieve this effect. So, installing rods and panels above the top is acceptable, especially if they are not planning to add a valance to their curtain setup. 

Should Curtains Sit On Window Sill?

If a homeowner prefers their curtains to hang just by their window sill, they can do that, especially for bathroom windows, kitchen sinks, or other smaller windows around the house. A prime example of curtains sitting on top of the sill is café windows or those near radiators, mostly seen in city apartments.
