What length curtains do I need?

Word on the street is that your curtains need to graze the floor. But windows are different sizes! Apartment windows are different from penthouse windows and so on.

You’ll need to properly measure up the length of your requirement and get enough fabric for the perfect length. But when it comes to measuring: where do you start?

Here’s a tip: you want to go about 10 inches wider than your window. In terms of length, you want the rod to start 12 to 24 inches above the window trim.

Standard Curtain Lengths

If you don’t want to invest a large sum of money in custom-made curtains, you can always go with one of the standard curtain lengths! The sizes you will come across in the standard market are:

  • 63 inches
  • 84 inches
  • 94 inches
  • 108 inches
  • and 120 inches.

This doesn’t mean you don’t have to take measurements. It just means rounding off to the closest standard size that’s available.

It’s the 108 inches and 96 inches that work well in most homes. Anything lower usually ends up looking funny.

Pro tip: you want a look of high and might with long curtains because it adds drama and accentuates high ceilings.

Before we dip into sizes, you must know the terms of the market. A relaxed gather in your curtains refers to those spread widely across the rod. There won’t be as many folds, so you’ll need relatively less material.

But a full gather will have more folds on the rod and require more fabric. Now let’s look at the curtain length size chart to get the exact idea.

Curtain Length Rules

Here are some more tips to keep in mind about the curtain length rules. However, remember that it also depends on the window size you’re working with.

1. Do not hang them too low.

Sure, puddle curtains are a thing. But not if you’re not able to keep up with the high maintenance it requires. You want yours to be half an inch above the floor.

That is enough to cover unwanted toddler paintings on the wall and ugly radiators. A short height can reduce the appearance of the ceiling by half instantly.

2. Make them wide enough

Length is surely an issue, but width is even more so. Don’t go and bring the exact width of your window in curtain width too! Remember, they will fold over and sway in the breeze. You’re looking for something at least 5 inches wider than your window on either side.

3. Install the rod correctly

The rod also shouldn’t be the exact width of the window. It should be higher from the window by at least 12 inches and wider than your window frame. If you decide to open up a window one day and the rod comes in the way, you know you’ve gone too low.

4. Modify where required

Apron drapes are those that are worn like skirts on only the bottom halves of windows. These are more common around the kitchen areas. They can be placed in nooks and corners where light is more acceptable during the day. It includes places like a living room nook or dining table where you aren’t seated that long.

5. Don’t hold up on the fabric

You’re going to need as much as it is needed to cover the windows and add a dramatic flair. Since the rods will be placed higher up, your measurements need to add a couple more inches. It’s done to ensure the fabric doesn’t end up short.

6. Make sure they match the hardware and curtain rods

You’ll want a type and design that matches the hardware and curtain rods. Drapery should show the fullness of the curtains and window treatments provide. It should create a space where you feel at home, as if a designer lives there. The curtain panels play a role as well.

You might even make sure the linen, furniture, and pillows match. Pinterest is a great place to get inspiration, examples, & help. When you’re working with curtains, you’ve got more leeway than when you’re working with blinds.

Your options are many, depending on whether they’re for entryways or high-ceiling areas. Floor-length can be popular in bedrooms.

Some thing will look good on 14-foot ceilings, while others look better with 9-foot ceilings.

Here’s how you can get started:

Time needed: 5 minutes.

How to choose the right curtain length?

  1. Mark up!

    You’ll need to decide if you want puddle length, aprons, window sills, or just plain floor length. Mark the wall with chalk where you want the bottom of the curtain to end. Now mark where you want the rod to go a couple of inches from the top of the window.marking up curtains

  2. Measure up!

    Get a metal measuring tape ready, and keep a ladder or stool handy. Now depending on what look, you’re going to start measuring from the top to the top of the window where the rod will go. Make sure to have a steady footing and not end up on the floor.measuring curtains

  3. Side to side!

    Now that the length is all set up, you can move on to the width. Decide whether you want a relaxed gather or a full gather in your panels. This will decide how much coverage you need. Make your marks for the width a couple of inches extra on either side of the window as curtains will never sit straight. They’re meant for flying! Now measure up and note down your measurements.side view of curtains

  4. Round up

    If you’re going for a customized drape, you can simply hand over these measurements to your upholstery shop with some added inches considering the gathering. Maybe you are going towards a standard cut to save the money and hassle. You’re going to need to round up to the closest standard size available.

How wide should they be?

Consider that they should cover your window neatly and still put up a nice flair in the room with its gathered folds. They should be more than the measurement of the window.

As a rule of thumb, if you plan to close them during the night, get the fabric in double or even 2.5x the width of the window. It will drape nicely, and you won’t find yourself pulling them tightly shut at the slightest breeze.

If you plan to keep your drapes open and are just planning to do up the window a little, you can buy fabric that is 1.5 times the width of the window.

Here are some burning questions everyone has about their upholstery. Do you want to-the-floor ones? We hope this blog’s information has helped spice up your home’s curtains and decor! Keep reading on this site for more inspiration on different types. We hope you have a pleasant experience!

Where should curtains fall?

They should ideally fall about 1/2 inch above the floor. This makes it seem like they are floor length but also don’t get dirty because they aren’t touching the floor. There are other styles that ignore this rule—for instance, the apron style or puddle fall. Short ones are also rule breakers and are more practical for bedrooms and bathrooms.

Puddle curtains will be extra long and will run a couple of inches of fabric on the floor for an accented look. These are great if you want to create a romantic or vintage vibe. They are quite common in heritage hotels for the same reason.

What lengths do curtains come in?

Standard-length curtains are a great option if you want to renovate your home for less money and quickly.
You can get short ones like a 63″ or an 84″. However, the suitable ones are usually 96″ and 108″ since they are the appropriate lengths. Others generally end up looking awkwardly short.

How much longer should the curtains be than the window?

Width-wise, the curtain rod should extend well beyond the window. It is usually 4-5 inches on either side. In terms of length, you will want to have something nearly touching the floor. So that means about half an inch above the floor, so they don’t get dirty. If you’re going for a puddle-gathered look, they will extend 4-5 inches on the floor for an accentuated look.

How far should the curtain hang below the windowsill?

It depends on where the window is and what look you are going for. If you’ve got a bedroom window, you can have short curtains extending slightly off the windowsill. That means around 1-2 inches. It can also be applied to kitchens, where you can employ the use of apron curtains that only cover half the window. This enables you to keep an eye on the kids playing in the front yard while doing the dishes.

How high should you hang curtains?

Your rod should not go directly above the window frame. Instead, it should be put up a couple of inches above the frame to make the windows look bigger and the ceiling looks higher. As a rule of thumb, you can install the rod about 3-6 inches above the window frame. No more than 6 inches is recommended. They might otherwise look off, especially when the bright light filters through them.

Should curtains touch the floor?

Unless you’re going for a puddle gather like in hotels, castles, and mansions, your curtains should not touch the floor. If you let them slide on the floor, there’s no end to the errands you’ve just added to your list of usuals. You will need to wash them more often because the floor will make their edges dirty. You will also need to vacuum and clean more strenuously in that area. Trash and dust are likely to gather behind and stick to the curtains.

Can you use short curtains on tall windows?

You certainly can! But remember that they shouldn’t be trailing off at an awkward length. In kitchens and bathrooms, it’s more common to have short curtains on a small window. The length is only about one or two inches extra of the window sill.

Can you use long curtains on small windows?

Yes! This is a trick often adopted to give off the impression of larger windows. Although you shouldn’t keep the curtains too oversized, it’s a good idea to keep them high above. If you have got different-sized windows in the same room, pick one size and stick to it. Your rod can settle around 5-6 inches above the window frame, but all of them should ideally end at the same point.

How do I clean curtains?

This depends on the fabric you have. You can easily spin them in the machine if it’s light satin. But they will probably need a dry cleaning session if these are heavier. Although most light fabrics are super easy to clean, they cannot be put in the wash directly. You will need to take out any hooks and any other metal fittings. Anything with grommets will need additional care, and it’s best you hand wash them.

When should you not hang curtains?

If you’ve got a breathtaking view that shouldn’t be missed, you can probably skip the curtains. Maybe you live in a relatively stranded area like a farmhouse. You can skip them since privacy won’t be a concern, especially in the living room. You could also go without them if you haven’t got too much natural light. If you live in a blocked apartment with little sun, it’s probably a good idea to let the sun in and skip the curtains.

If you’re going for a modern contemporary vibe, you can skip them too. Penthouses with large open spaces and glass windows from floor to ceiling are common. Curtains would certainly get in the way of that view!

What to consider when buying curtains?

The first one on the list is the purpose. If you know the purpose of the curtain is to block out light, you’ve got to go for the heavier fabric. Plain, old satin won’t do. A sheer curtain works nicely if you’re only looking for decorative purposes. Your purpose decides the fabric. But you should also consider the room in question. What is the size of the room? Do you need to make it look larger or taller? That will decide the size.

The color is tricky. If you’ve got strong shades of wall colors, it’s best to stick to something neutral in the curtains. But they can just as easily become focal points if you don’t have one. Pair velvet ones with sheer ones, and your windows will look straight out of a fairytale.
