How We Size Windows:

Here’s a simple step-by-step list you can use for how to choose the right window sizes in Boise. We can help you with this and walk you through the entire process!

1. Measure the opening (width x height)

Use a tape measure and measure the inside of the window opening in three spots (top, middle, bottom for width; left, center, right for height). Write down the smallest numbers.

2. Check Boise building codes & egress rules

For bedrooms and basements especially, make sure the window size meets local egress requirements for safety and resale value.

3. Match the style to the room’s function

Match room styles with these ideas:

Large picture windows for views/light
Double-hung or sliders where you need airflow
Casement or awning windows for tight spaces (like over sinks)

4. Consider Boise’s climate when sizing

Bigger windows mean more light, but also more potential heat loss in winter and heat gain in summer. Strike a balance between your desire for views and energy efficiency.

5. Look at wall space and furniture layout

Ensure the window size won’t conflict with furniture, beds, or TVs, and that you’ll have sufficient room for blinds or curtains.

6. Check standard vs. custom sizes

If your opening is close to a standard size, you’ll usually save money. Odd-sized or huge openings may require custom windows.

7. Think about curb appeal from the street

Ensure that window sizes align with each other and appear balanced on the front of your Boise home.

8. Ask a local pro to confirm your measurements

Before you order, have a Boise window specialist like us (Legacy Roofing) double-check sizing so you don’t get stuck with windows that don’t fit.

What Are the Best Window Styles for Boise Homes?

Did you search “How to choose window sizes Boise” in hopes of finding a guide to help you with the best styles and sizes? Just being honest, Boise’s weather doesn’t make it easy on windows.

Summers can hit the 90s while winters drop below freezing. That’s why the best window styles for local homes are those built to handle both extremes while still keeping energy bills manageable. Below are the top-performing options that combine function, beauty, and value, and how we typically explain windows to our clients!

1. Double-Hung Windows

These are the classic two-sash windows that slide up and down. They allow airflow from both the top and bottom, making them perfect for controlling ventilation in Boise’s dry summers. Easy to clean and widely available, double-hung windows work well for most home designs and budgets.

2. Casement Windows

Casement windows open outward with a crank, sealing tightly when closed. They’re among the most energy-efficient styles available and are great for catching cross breezes. Their tight seal makes them ideal for winter insulation and noise reduction near busy streets.

3. Picture Windows

Picture windows don’t open, but they deliver panoramic views and natural light. They’re perfect for scenic Boise neighborhoods such as the Foothills or Eagle, where the landscape deserves to be framed. Combine them with smaller operable windows nearby for airflow.

4. Sliding Windows

Sliding windows operate on a horizontal track, which makes them easy to open and maintain. They’re a strong fit for modern or mid-century homes and let in generous daylight. Their simplicity keeps costs reasonable while still offering solid energy performance.

5. Awning Windows

These hinge at the top and open outward from the bottom, allowing ventilation even during light rain. They’re often placed above sinks or bathrooms where privacy and airflow matter most. Their design also helps shed water away from the window opening, adding extra protection.

Simple Window Style Diagram

Which window style is best for your home? It really depends on your budget and the current windows in your home. Below is a straightforward layout that helps visualize how each window type functions:

Window Type	Opening Direction	Ideal Use	Key Benefit
Double-Hung	Vertical (up and down)	Bedrooms, living rooms	Balanced airflow
Casement	Outward (side hinge)	Kitchens, windy areas	Energy-efficient seal
Picture	Fixed (non-opening)	Living rooms, scenic areas	Maximum light and view
Sliding	Horizontal (side to side)	Modern homes, patios	Smooth operation
Awning	Outward (top hinge)	Bathrooms, above sinks	Ventilation during rain

Choosing a mix of these styles can balance airflow, insulation, and light in every season while complementing your home’s structure.

Which Window Styles Match Boise’s Unique Architectural Designs?

Boise homes range from craftsman bungalows to sleek modern builds. Each benefits from a window style that complements its structure and climate.

Craftsman or Bungalow Homes: Double-hung and casement windows keep the classic charm while improving airflow and insulation.
Modern or Contemporary Homes: Picture and sliding windows highlight clean lines and open up the view.
Farmhouse or Country Homes: Tall double-hung windows bring in natural light and preserve traditional character.

Matching your window style to your architecture enhances curb appeal, improves energy performance, and promotes comfort without clashing with your home’s design.

How Do Picture, Awning, and Bay Windows Enhance Boise Homes?

What window will add curb appeal and value to your home? Picture Windows are not as functional, but these three window types are favorites for homeowners who want both form and function.

Picture Windows: Fixed glass panels that frame Boise’s landscapes while keeping drafts out. Great for energy efficiency and scenic views.
Awning Windows: Open from the bottom, allowing airflow even during rain. Ideal for kitchens and bathrooms.
Bay Windows: Extend outward, creating more interior space and adding architectural interest. Perfect for reading nooks or living areas.

Each adds natural light, boosts value, and creates visual appeal that stands out in Boise’s diverse neighborhoods.

When Should You Consider Specialty, Sliding, or Egress Windows in Boise?

These window types serve specific needs that many homeowners overlook.

Specialty Windows: Custom shapes or designs used for accent walls or high ceilings. Ideal for adding light without sacrificing privacy.
Sliding Windows: Ideal for modern layouts or tight spaces where vertical openings are impractical. Simple to use and easy to maintain.
Egress Windows: Required for basements and bedrooms to meet safety codes. They also add to the resale value and provide natural light below ground level.

Choose these options when function, safety, or design flexibility are your top priorities.

How Do You Determine the Right Window Size for Boise Houses?

Window sizing is a combination of part math, part logic, and a bit of visual sense. Follow these steps to keep your home bright, balanced, and efficient:

Measure the Wall Space. Start with the opening width and height, not just the frame. This prevents fitting issues later.
Account for Framing and Trim. Subtract roughly half an inch from both dimensions to allow for leveling and insulation gaps.
Consider Room Purpose: Living rooms benefit from larger windows to allow for more light and a better view. Bedrooms and bathrooms need privacy and moderate ventilation.
Factor in Sun Direction: South-facing walls in Boise get more heat. Choose slightly smaller or shaded windows there to reduce glare and energy use.
Check Code and Structure Limits. Some exterior walls can’t support oversized windows without added framing.

Disclosure: Certain measurements, structural checks, and installations should always be confirmed by a licensed contractor or window professional.

What Is the Golden Rule for Window Sizing in Boise Homes?

In Boise, the golden rule is to keep the window area around 15 to 20 percent of the room’s floor space. That ratio brings in daylight without turning your home into a greenhouse. Large south-facing windows capture winter warmth, while shaded or smaller north windows prevent summer glare. Balanced sizing looks intentional, performs well, and keeps your home comfortable throughout the year.

How Do You Accurately Measure Windows for Replacement in Boise?

Even the best window will fail if it’s mismeasured. Here’s how pros get it right every time.

Step 1: Measure Width in Three Places. Take readings at the top, middle, and bottom of the frame. Always use the smallest number as your final width.

Step 2: Measure Height in Three Places. Check both sides and the center, then choose the option with the smallest height to ensure a snug fit.

Step 3: Don’t forget to measure the depth from the inside trim to the exterior stop. This helps confirm if you need a standard or custom frame.

Step 4: Record and Double-Check Write each number clearly, and repeat the process. A quarter inch can make or break your installation.

Expert Tip: Always measure from the interior side of the window. It’s the most accurate way to capture the true frame size and avoid ordering a window that doesn’t fit.

What Are Standard vs. Custom Window Sizes for Boise Residences?

Remember the scene in Goldilocks and the Three Bears? One chair was too big, one too small, and one just right. Windows work the same way. Standard sizes are designed to fit most openings in newer Boise homes and are less expensive to install. Custom sizes, on the other hand, are tailored for older houses or unique designs where no two openings match. The standard is affordable and straightforward; the custom option is perfect when precision, symmetry, or style matter most.

Choosing between them depends on your priorities. If you’re updating a modern build, standard windows often deliver outstanding performance at a lower cost. However, if your home has settled walls, curved frames, or vintage trim, custom windows provide a cleaner fit and improved efficiency. In short, the right size isn’t about budget alone; it’s about matching your window to your home’s story.

Why Is Professional Window Installation Important for Boise Homes?

Hiring a pro for your window installation is like hiring a trusted mechanic instead of watching a tutorial and hoping for the best. Boise homeowners get peace of mind and long-term savings for several good reasons:

Properly fitted and Sealed Professionals ensure the window sits square, sealed, and supported, preventing leaks and air gaps.
Energy Efficiency: A tight fit helps your home maintain temperature, lowering heating and cooling costs year-round.
Code Compliance Boise has specific building codes for egress and insulation. Certified installers know them and handle the permits correctly.
Warranty Protection Manufacturers often void warranties if certified pros don’t install windows. It’s insurance for your investment.
Safety and Structural Integrity Pros have the right tools and training to prevent damage to walls, siding, or glass during installation.

How Does Professional Installation Improve Window Performance?

Changing your own windows might sound easy until gravity disagrees. A bad install can turn a tight seal into a leaky mess. Professional installers know how to balance precision and safety, just as a pilot handles turbulence. They level each frame, secure insulation evenly, and test every latch before calling it done. That accuracy improves energy savings, reduces noise, and prevents long-term wear and tear. In short, skilled installation keeps your windows functioning like new for years, not just months.
