How to Choose Curtains for a Room: A Simple Guide for Real Homes

Choosing curtains sounds easy, until we hang them and something feels wrong.
Maybe they look too short. Maybe the colour changes in daylight. Maybe the room feels darker or colder than we expected.

Curtains do much more than cover glass. They affect light, privacy, warmth, and how big or small a room feels. When we know how to choose curtains for a room, we save money, avoid stress, and get a space that feels right.

What Curtains Change in a Room

Before we start shopping, it helps to know what curtains really do. They can change:

How much natural light comes in
Daytime and night‑time privacy
How warm or cool the room feels
How high the ceiling seems
How wide the window looks
How soft and “finished” the room feels
How much outside noise we hear with some fabrics

Once we understand these points, it becomes easier to choose curtains that match the way we live, not just the way a room looks in a photo.

Step 1: Measure Your Windows the Right Way

Many people guess their curtain size and regret it later. Good measurements are the first step when we decide how to choose curtains for a room.

How wide should curtains be?

Curtains should be wider than the window. If they match the window width, they look flat and tight.

A simple rule:

Measure the window width.
Multiply that number by 1.5 to 2.

Example:

Window width: 60 inches
Minimum curtain width: 90 inches (60 × 1.5)
Ideal curtain width: 120 inches (60 × 2)

This gives the fabric enough fullness so panels look soft, not stretched.

How high should we hang the curtain rod?

Rod height changes how tall the room feels.

In most rooms, install the rod about 4–6 inches above the window frame.
In rooms with low ceilings, many of us like to go closer to the ceiling line.

Raising the rod draws the eye up and makes the room feel taller.

How long should curtains be?

We can choose from a few common lengths:

Sill length – Ends right at the window sill (often used in kitchens).
Apron length – Ends a few inches below the sill.
Floor length – Most popular for living rooms and bedrooms.
Puddle length – Extra fabric resting on the floor for a formal look.

For most homes, floor‑length curtains that just touch the floor, or sit about half an inch above it, give a neat and modern feel.

Step 2: Pick the Right Fabric

Fabric choice can change everything about how a room feels. When we think about how to choose curtains for a room, fabric is one of the first big decisions.

Here is a simple table to compare common options:

Curtain type	Light control level	Best rooms	Main benefit
Sheer curtains	Low	Living rooms, dining areas	Soft daylight and gentle privacy
Linen or cotton	Medium	Most bedrooms and living areas	Natural look and easy everyday use
Blackout curtains	High	Bedrooms, nurseries, media rooms	Darker room and better sleep
Thermal curtains	Medium–High	Bedrooms, living rooms	Extra warmth and comfort

Sheer curtains

Let in soft, filtered light.
Provide privacy in the day, but not at night when lights are on.
Work well in living rooms or layered in front of blinds.

Linen or cotton curtains

Give medium light control.
Bring a relaxed, natural texture.
Work in most rooms, especially where we want a calm look.

Blackout curtains

Block a large amount of light.
Help people who are light‑sensitive, night‑shift workers, or parents with young children.
Often used in bedrooms and media rooms.

Thermal curtains

Include extra lining to slow heat loss and heat gain.
Add weight and help rooms feel steadier in temperature.
In colder places, such as Edmonton winters, they can make a room feel more comfortable when the temperature drops outside.

Studies on window coverings show that well‑fitted curtains and blinds can reduce heat loss through windows by around a quarter, which can help with energy bills and comfort in cooler seasons.

Step 3: Match Curtains to the Room’s Purpose

Each room has a different job, so curtains should match that job.

Living room

Often needs both light and privacy.
Many people like layered window treatments: sheer curtains for daytime, plus heavier panels for evenings.
If the room faces a busy street, thicker fabrics can help soften traffic noise a little.

Bedroom

Dark, quiet spaces work better for sleep.
Blackout or thermal curtains are helpful, especially in summer months or near streetlights.
Layering with blinds gives more fine‑tuned control.

Home office

We want natural light but less glare on screens.
Light‑filtering fabrics like cotton, linen, or lined sheers work well.

Small rooms

Light colours keep the room from feeling cramped.
Floor‑length panels hung a bit higher can make walls seem taller.
Simple patterns or plain fabrics are easier on the eye in tight spaces.

In many Edmonton homes, we see large living room windows and cooler seasons, so choosing curtains that balance light control with warmth is very helpful.

Step 4: Choose the Right Colour

Colour completely changes the mood of a room.

We can go in two main directions:

Blend: Pick a curtain colour close to the wall colour for a calm, soft look.
Contrast: Pick a darker or bolder colour that stands out as a feature.

Light colours:

Help rooms feel larger and brighter.
Work well in small spaces or north‑facing rooms that get less sun.

Dark colours:

Add depth and a cosy feel.
Work well in large rooms or where we want a bit more drama.

It is smart to test curtain fabric in the actual room, near the window, during the day and at night. Store lighting often makes colours look quite different from how they look at home.

Step 5: Avoid Common Curtain Mistakes

A few simple errors can spoil an otherwise good choice. Here are the main problems we see:

Panels that are too short for the window and wall
Not enough width, so curtains do not look full
Rods hung too low, which make ceilings feel shorter
Very heavy fabric in an already dark room
No thought for warmth or cooling needs
Forgetting about night‑time privacy on busy streets

When we avoid these issues, our window treatments feel more “designed” and less like an afterthought.

Should We Pair Curtains with Blinds?

Using both blinds and curtains on the same window gives more control.

For example:

Blinds handle daily light level and privacy.
Sheer curtains soften the look of the window and filter daylight.
Darker or blackout panels on top help at night or when we want a darker room.

This layered style works especially well in bedrooms, living rooms, and front rooms that face the street.

Quick Curtain Buying Checklist

Before we buy, it helps to go through a short checklist:

Window width measured correctly
Curtain width set to about 1.5–2 times the window width
Rod height chosen and marked
Curtain length (sill, apron, floor, or puddle) decided
Fabric chosen based on light and privacy needs
Colour tested in room lighting, not just in the store

If we can tick these boxes, we are in a strong place to choose curtains for a room with confidence.

Frequently Asked Questions

How do we know what size curtains to buy?

Measure the window width and multiply that number by 1.5 to 2 for fullness. Then measure from the planned rod height down to the length you want (sill, apron, or floor).

Should curtains touch the floor?

Floor‑length curtains are the most common choice in living rooms and bedrooms. They can just touch the floor or sit about half an inch above for easier cleaning.

What curtains make a room look bigger?

Light‑coloured, floor‑length curtains hung higher than the top of the window help walls look taller. Keeping patterns simple also makes small rooms feel more open.

Do sheer curtains give enough privacy?

In the daytime, sheer curtains blur the view and give light privacy. At night, when indoor lights are on, they do not offer full privacy on their own.

Are blackout curtains only for bedrooms?

No, many people use them in media rooms, nurseries, or home offices where they want less glare. They also help in rooms that face bright streetlights.

What is the most common curtain mistake?

The most common problem is buying curtains that are too short or not wide enough. Both make the window treatment look unfinished.

Can we use curtains and blinds together?

Yes, many homes mix blinds for fine light control with curtains for style and softness. This mix is popular on larger windows and patio doors.

What colour curtains work best with grey walls?

Soft whites, warm neutrals, and some muted blues or greens often pair well with grey walls. The right choice depends on the flooring and furniture as well.

Are thermal curtains worth it in a cold city like Edmonton?

Thermal curtains help reduce heat loss through glass and make rooms feel less drafty. In long winters, they can be a smart upgrade near older or larger windows.

How often should we replace curtains?

There is no strict rule, but many people change curtains every 5–10 years or when fabric fades, lining breaks down, or style changes. Regular washing or cleaning keeps them fresh in the meantime.

What is the easiest way to measure windows for curtains?

Use a metal tape measure, write down width and height, and decide rod height first. Then add extra width for fullness and decide if you want sill, apron, or floor length.

Which curtain fabrics are easiest to care for?

Cotton and many polyester blends are simple to clean and keep in shape. Heavier fabrics like velvet often need more careful care or professional cleaning.
