Struggling with Small Windows? Find Out What Works Best for Calgary Homes

If you wonder why some windows look clean, tall, and elegant while others feel tight or uneven, that one overlooked detail is– how the blinds are mounted.

Many Calgary homeowners, especially older builds, face the same frustration — windows that feel smaller than they should.

It could be shallow basement windows, character homes with unusual trims, older wood trims, uneven frames, or narrow openings that never seem to let in enough light. And when you start looking for window blinds in Calgary, the first big choice you’re asked to make is one most people don’t expect: inside mount or outside mount window blinds? 

This single decision changes how large your windows look, how much light your room gets, and how finished the space feels.

Let’s make this simple, clear, and designed around real Calgary homes for you to understand how each mount works, when to choose one over the other, and how the right installation makes all the difference.  

Inside Mount Window Blinds

An inside mount is when the blind or shade fits within the window frame, sitting flush with the trim.

Why homeowners love it:

• Clean, minimalist look
  
• Ideal for layered looks with curtains
  
• Showcases beautiful wood trim
  
• Fits well if you already have deep frames
  

What to check before choosing an inside mount:

• Do you have enough depth for the blind?
  
• Are the window edges straight, not uneven?
  
• Is the frame wide enough to hide small gaps?
  

Inside mounts work beautifully in newer Calgary homes, condos, and spaces where the window trim is symmetrical.

Outside Mount Window Blinds

An outside mount is installed on the wall or on the window frame, sitting in front of the frame with a slight overlap around the edges. This style is often chosen for its ability to create a larger, more balanced look, or when the window doesn’t have enough depth for an inside mount.

Why this is a game-changer for small spaces:

• Makes small windows look wider
  
• Adds height to low or squat windows
  
• Covers uneven frames and gaps
  
• Reduces side light leaks
  
• Perfect for shallow or old window casings
  

This option works especially well in many Calgary homes built before the early 2000s — homes that often have limited depth, narrow trims, or frames that aren’t perfectly even.

Inside vs Outside Mount: Which One Makes Windows Look Bigger?

If you want to make a window look taller, wider, or more balanced, then an outside mount offers the strongest visual lift.

Here’s how:

1. Adds Height

Mounting blinds above the trim draws the eye upward.
This simple shift adds a sense of height — suitable for basements or homes with lower ceilings

2. Adds Width

If your windows feel narrow, extending the blind a few inches past each side creates the impression of a broader frame and makes the room feel more open.
This works especially well on older windows with thick trims or recessed edges.

3. Cleaner Lines

Outside mounts create a smooth rectangle that hides uneven wood or older trim.
This helps reduce visual noise and makes the window area look newer and neater.

On the Contrary, Inside Mount Preserves the Real Shape

Inside mounting doesn’t hide the true size of the window, so it works best only if the frame is already well-proportioned and deep.

Which Mount Is Better for Calgary Basement Suites?

Calgary basements often have:

• Smaller windows
  
• Limited frame depth
  
• High light-contrast
  
• Privacy concerns
  

Outside mounting window blinds almost always offers better results here.

It helps soften the harsh outline of small basement windows and lets in more light when raised. As mentioned, an outside-mounted blind placed slightly above the window gives the illusion of a larger opening — making the space feel less confined.

Which Mount Works Best for Older Calgary Homes?

Many older homes in Calgary have:

• Shallow trims
  
• Uneven casing
  
• Warped wood over time
  
• Limited space for hardware
  

Inside mount often becomes impractical.
Outside mount solves these issues instantly by bypassing the frame entirely and creating a clean, straight, balanced look.

Inside Mount: When It’s Still the Best Choice

Inside mount blinds are a great option when your window has:

• Enough depth for brackets
  
• Even trimming
  
• Clean edges
  
• A shape worth highlighting
  

This style works well with roller blinds, pleated blinds, honeycomb shades, and zebra blinds.
It’s elegant in spaces where simplicity matters — like modern living rooms or minimalist bedrooms.

Outside Mount: A Practical Choice for Many Calgary Homes

Calgary has many older houses with framed windows that aren’t perfectly straight.
You’ll also find shallow sills, basement windows set close to the ceiling, and narrow openings split by mullions.

Outside mount solves these issues without renovation.

When an outside mount shines:

• Basement windows with little depth
  
• Uneven or warped trim
  
• Bright south-facing rooms needing blackout
  
• Rooms that feel closed-in
  
• Windows set low on the wall
  
• Spaces that could benefit from added height
  

It’s not just a design trick — it improves light control too.

Light Control: Inside vs. Outside Mount Blinds Performance

Inside Mount

• Softer light filtering
  
• Clean daytime glow
  
• Slight light gaps on the sides
  

Outside Mount

• Better for blackout needs
  
• Reduces glare from Calgary’s summer sun
  
• Covers more area for improved privacy
  
• Ideal for bedrooms and media rooms
  

If you’re sensitive to light or if the room faces long summer daylight hours, outside mount is often the more reliable choice.

Privacy: What Calgary Homeowners Should Know

For homes closer to the street or with neighboring houses overlooking, outside mount blinds give wider coverage, reducing visibility from angles.

Inside mount also offers privacy, but may leave small gaps depending on frame shape.

How to Measure for Each Mount (Simplified Guide)

Inside Mount Requires:

• Accurate frame width at top, middle, bottom
  
• Depth measurement
  
• Straight framing
  

Outside Mount Requires:

• Desired width (usually 2–4 inches beyond frame)
  
• Desired height (often 3–6 inches above frame)
  
• Enough wall or trim surface for secure installation
  

Professional measurement ensures proper alignment, light coverage, and fabric tension — especially helpful for Calgary’s varied window types.

Which Window Blinds in Calgary Styles Best for Each Mount?

Inside Mount Friendly:

• Pleated blinds
  
• Zebra blinds
  
• Roller blinds
  
• Honeycomb blinds
  

Outside Mount Friendly:

• Blackout roller blinds
  
• Pleated blinds for small windows
  
• Zebra blinds for wider coverage
  

Most window blinds can go either way, but the look and function change depending on how they’re mounted.

Common Window Setups & Ideal Mount Choices

Shallow basement window → Outside mount

Older window with aging trim → Outside mount to hide irregularities

Tall modern window with deep frame → Inside mount

Narrow bedroom window that needs blackout → Outside mount

Decor-focused living room with curtains → Inside mount

South-facing room with glare → Outside mount for coverage

Local architecture, daylight patterns, and your home’s layout all play a great role — which is why understanding your window’s structure matters.
